result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, COULD

result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, MAY

result in minor or moderate injury.

This symbol is used to alert the user to useful information about proper

operation of the equipment, and/or a situation that may cause damage

to the machinery.

NOTICE

Standard Safety Instructions

1. READ THROUGH THE ENTIRE MANUAL BEFORE STARTING MACHINERY. Machinery presents serious

injury hazards to untrained users.

2. ALWAYS USE ANSI APPROVED SAFETY GLASSES WHEN OPERATING MACHINERY. Everyday eye-

glasses only have impact resistant lenses—they are NOT safety glasses.

3. ALWAYS WEAR AN NIOSH APPROVED RESPIRATOR WHEN OPERATING MACHINERY THAT PRODUCES

DUST. Wood dust is a carcinogen and can cause cancer and severe respiratory illnesses.

4. ALWAYS USE HEARING PROTECTION WHEN OPERATING MACHINERY. Machinery noise can cause

permanent hearing damage.

5. WEAR PROPER APPAREL. DO NOT wear loose clothing, gloves, neckties, rings, or jewelry which may

get caught in moving parts. Wear protective hair covering to contain long hair and wear non-slip

footwear.

6. NEVER OPERATE MACHINERY WHEN TIRED, OR UNDER THE INFLUENCE OF DRUGS OR ALCOHOL.

Be mentally alert at all times when running machinery.

7. ONLY ALLOW TRAINED AND PROPERLY SUPERVISED PERSONNEL TO OPERATE MACHINERY. Make

sure operation instructions are safe and clearly understood.

8. KEEP CHILDREN AND VISITORS AWAY. Keep all children and visitors a safe distance from the work

area.

9. MAKE WORKSHOP CHILD PROOF. Use padlocks, master switches, and remove start switch keys.

W1772/W1773 37" Drum Sander

10. NEVER LEAVE WHEN MACHINE IS RUNNING. Turn power off and allow all moving parts to come to

a complete stop before leaving machine unattended.

11. DO NOT USE IN DANGEROUS ENVIRONMENTS. DO NOT use machinery in damp, wet locations, or

where any flammable or noxious fumes may exist.

12. KEEP WORK AREA CLEAN AND WELL LIT. Clutter and dark shadows may cause accidents.

13. USE A GROUNDED EXTENSION CORD RATED FOR THE MACHINE AMPERAGE. Undersized cords over-

heat and lose power. Replace extension cords if they become damaged. DO NOT use extension cords

for 220V machinery.

14. ALWAYS DISCONNECT FROM POWER SOURCE BEFORE SERVICING MACHINERY. Make sure switch is

in OFF position before reconnecting.

15. MAINTAIN MACHINERY WITH CARE. Keep blades sharp and clean for best and safest performance.

Follow instructions for lubricating and changing accessories.

16. MAKE SURE GUARDS ARE IN PLACE AND WORK CORRECTLY BEFORE USING MACHINERY.

17. REMOVE ADJUSTING KEYS AND WRENCHES. Make a habit of checking for keys and adjusting

wrenches before turning machinery ON.

18. CHECK FOR DAMAGED PARTS BEFORE USING MACHINERY. Check for binding and alignment of

parts, broken parts, part mounting, loose bolts, and any other conditions that may affect machine

operation. Repair or replace damaged parts.

19. USE RECOMMENDED ACCESSORIES. Refer to the instruction manual for recommended accessories.

The use of improper accessories may cause risk of injury.

20. DO NOT FORCE MACHINERY. Work at the speed for which the machine or accessory was designed.

21. SECURE WORKPIECE. Use clamps or a vise to hold the workpiece when practical. A secured

workpiece protects your hands and frees both hands to operate the machine.

22. DO NOT OVERREACH. Keep proper footing and balance at all times.

23. MANY MACHINES WILL EJECT THE WORKPIECE TOWARD THE OPERATOR. Know and avoid condi-

tions that cause the workpiece to "kickback."

24. ALWAYS LOCK MOBILE BASES (IF USED) BEFORE OPERATING MACHINERY.

25. BE AWARE THAT CERTAIN DUST MAY BE HAZARDOUS to the respiratory systems of people and

animals, especially fine dust. Make sure you know the hazards associated with the type of dust you

will be exposed to and always wear a respirator approved for that type of dust.

Additional Safety for Drum Sanders

READ and understand this

entire instruction manual

before using this machine.

Serious personal injury

may occur if safety and

operational information is

not understood and fol-

lowed. DO NOT risk your

safety by not reading!

USE this and other machinery with caution

and respect. Always consider safety first,

as it applies to your individual working

conditions. No list of safety guidelines can

be complete—every shop environment is

different. Failure to follow guidelines could

result in serious personal injury, damage

to equipment or poor work results.

1. FEEDING STOCK. Do not stand in the direct path of a workpiece at the infeed end when feed-

ing your stock. Never sand more than one piece of stock at a time. DO NOT jam the workpiece

into the machine during operation. Firmly grasp the workpiece in both hands and ease it into the

machine using light pressure.

2. MINIMUM STOCK DIMENSIONS. Do not sand any stock thinner than ¹/16", narrower than 2", or

shorter than 9". Do not sand thin stock by using a “dummy” board under your workpiece.

3. SAFETY COVERS. All covers must be closd and in place before starting machine.

4. CLOTHING. Do not wear loose clothing while operating this machine. Roll up or button long

sleeves at the cuff.

5. HAND PROTECTION. Do not place hands near, or in contact with, sanding drums during operation.

DO NOT allow fingers to get pinched between board and conveyor belt during operation. This may

pull the operator’s hand into the machine and cause serious injury or death!

6. INSPECTING WORKPIECES. Always inspect one workpiece at a time for nails, staples, knots, and

other imperfections that could be dislodged and thrown from the machine during sanding opera-

tions. Do not use workpieces with these defects.

7. DUST COLLECTION SYSTEM. Never operate the sander without an adequate dust collection system

in place and running.

8. BE ATTENTIVE. Never leave the machine running unattended.

9. REPLACING SANDING PAPER. Replace sanding paper when it becomes worn or damaged.

10. EXPERIENCING DIFFICULTIES. Any problem, with the exception of conveyor belt tracking, that

is concerned with any moving parts or accessories, must be investigated and corrected with the

power disconnected, and after all moving parts have come to a complete stop.

11. MAINTENANCE AND ADJUSTMENTS. Never attempt to adjust conveyor belt tracking when the

sanding drums are running. Perform machine inspections and maintenance service promptly when

called for. Disconnect power before performing maintenance or adjustments to the sander.

12. RESPIRATOR AND SAFETY GLASSES. Always wear a respirator and safety glasses while operating

the machine. Dust and chips are created when sanding. Some debris will be ejected, becoming

hazards to the eyes and lungs.

Figure 3. Locking shutoff switch.

The Model W1773 is prewired for 220V 3-phase operation,

but may be rewired for 440V 3-phase operation (see Page

13).

This machine must be hardwired to a locking shutoff

switch by a qualified electrician. Hardwiring involves a

permanent installation with conduit runs that can only be

accomplished safely by a qualified electrician. As always,

observe all applicable electrical codes when connecting

this machine to power.

This machine must be grounded! Verify the ground before

connecting this machine to the power source.

Attempting to connect this machine to

the power source without a qualified

electrician greatly increases the risk

of electrocution, fire, or machine

damage.

Phase Converter

The power from the manufactured power leg (wild wire)

of a phase converter fluctuates, which may damage elec-

trical components if connected to the wrong incoming

power terminal. If you must use a phase converter for

3-phase power, only connect the "wild wire" to the L1

terminal. The wire from the L1 terminal can handle some

fluctuation because it goes directly to the motor. The

power going to the L2 and L3 terminals connects to the

controls and must be consistent to prevent damage.

W1772/W1773 37" Drum Sander

Machine Placement

•

Floor Load: This machine distributes a heavy load in

a small footprint. Some residential floors may require

additional bracing to support both machine and

operator.

The Model W1772/W1773

is an extremely heavy

machine. Serious per-

sonal injury may occur if

safe moving methods are

not followed. To be safe,

you will need assistance

and power equipment

when moving the ship-

ping crate and removing

the machine from the

crate.

Working Clearances: Consider existing and

anticipated needs, size of material to be processed

through the machine, and space for auxiliary stands,

work tables or other machinery when establishing

a location for your drum sander (see Figure 13 for

minimum working clearances).

•

Lighting: Lighting should be bright enough to

eliminate shadow and prevent eye strain.

Electrical: Electrical circuits must be dedicated or

large enough to handle amperage requirements.

Follow local electrical codes for proper installation of

new lighting, outlets, or circuits.

Use lifting straps with a combined

minimum of 2000 lbs. lifting capacity.

If lifting straps break, serious personal

injury may occur.

MAKE your shop “child safe.” Ensure

that your workplace is inaccessible

to youngsters by closing and locking

all entrances when you are away.

NEVER allow untrained visitors in

your shop when assembling, adjust-

ing or operating equipment.

W1772/W1773 37" Drum Sander

Lifting Sander

To place the sander in a permanent location, do these

steps.

1. Unbolt the sander from the pallet.

2. Position the forklift forks directly above the sander.

Place two lifting straps with hooks on the ends over

the forklift forks and slide the hooks into the eye-

bolts shown in Figure 14.

3. Lift the sander and move it to your predetermined

location. DO NOT lift it any higher than is necessary

to clear the floor.

Figure 14. Lifting the sander.

Mounting to Shop Floor

Although not required, we recommend that you mount

your new machine to the floor. Because this is an optional

step and floor materials may vary, floor mounting hard-

ware is not included.

Anchor Stud

Bolting to Concrete Floors

Lag shield anchors with ³/8" lag bolts or anchor studs

(Figure 15) are two popular methods for anchoring an

object to a concrete floor. We suggest you research the

many options and methods for mounting your machine

and choose the best that fits your specific application.

Lag Screw and Anchor

NOTICE

Anchor studs are stronger and more permanent alter-

natives to lag shield anchors; however, they will stick

out of the floor, which may cause a tripping hazard if

you decide to move your machine at a later point.

Figure 15. Typical fasteners for mounting

to concrete floors.

Bolting to Wood Floors

��

The most secure method of mounting this drum sander to

a wood floor is using ³⁄8" hex bolts with flat washers, and

securing the bolts from under the floor with flat washers,

lock washers and hex nuts, as shown in Figure 16. Use lag

bolts with washers only if you do not have access to the

underside of the floor.

W1772/W1773 37" Drum Sander

Dust Collection

Recommended CFM at Sander: ................. 1600 CFM

Do not confuse this CFM recommendation with the rating

of the dust collector. To determine the CFM at the dust

port, you must take into account many variables, includ-

ing the CFM rating of the dust collector, the length of

hose between the dust collector and the machine, the

amount of branches or Y's, and the amount of other open

lines throughout the system. Explaining this calculation

is beyond the scope of this manual. If you are unsure of

your system, consult an expert or purchase a good dust

collection "how-to" book.

We recommend using a dust collection system that pro-

duces a minimum of 2000 CFM. A fine layer of dust will

be present on your stock as it comes out of the sander.

This is normal.

Figure 17. Dust port locations.

To connect the dust ports to a dust collector, do these

steps:

1. Attach 4" dust collection hoses to the dust ports

shown in Figure 17 and secure them with hose

clamps.

Power Connection

Before connecting to power, read through the

ELECTRICAL section on Page 11 to check that your

setup follows the safety and circuit requirements for this

machine. Be sure to also have your electrician on hand

for the "Test Run" in case the power is connected out of

phase (Model W1773 only).

To connect the sander to the power source, do these

steps:

1. Remove the screws securing the control panel and

Attempting to connect this machine to

the power source without a qualified

electrician greatly increases the risk

of electrocution, fire, or machine

damage.

2. Feed the power wires through the strain relief on

the bottom of the control panel, tighten the strain

relief, connect the cord to the terminals shown in

Figure 18 or 19, and reinstall the control panel face

plate.

Note (Model W1773 Only): When using a phase con-

verter, connect the manufactured power leg to the

L1 terminal (Figure 19). The L1 terminal can handle

power fluctuation because it is wired directly to the

motor. The other wires connect to the controls and

must be consistent to prevent damage.

Test Run

Once the assembly is complete, test run your machine to

make sure it runs properly and is ready for regular opera-

tion.

The test run consists of verifying the following: 1) The

motors power up and run correctly, 2) the motors turn

the correct direction (machine is not wired out of phase

(W1773 only), and 3) the stop button safety feature works

correctly.

Loose hair and clothing could get

caught in machinery and cause serious

personal injury. Keep loose clothing

rolled up and long hair tied up and

away from machinery.

General

The Model W1772/W1773 will perform many types of oper-

ations that are beyond the scope of this manual. Many of

these operations can be dangerous or deadly if performed

incorrectly.

OFF

DO NOT investigate problems or adjust

the machine while it is running. Wait

until the machine is turned OFF,

unplugged and all working parts

have come to a complete stop before

proceeding!

The instructions in this section are written with the under-

standing that the operator has the necessary knowledge

and skills to operate this machine. If at any time you are

experiencing difficulties performing any operation, stop

using the machine!

If you are an inexperienced operator, we strongly recom-

mend that you read books, trade articles, or seek training

from an experienced Drum Sander operator before per-

forming any unfamiliar operations. Above all, your safety

should come first!

Always wear safety glasses and a

respiratorwhenoperatingthismachine.

Failure to comply may result in serious

personal injury, allergic reactions, or

respiratory problems.

W1772/W1773 37" Drum Sander

Depth of Cut

The optimum depth of cut will vary based on the type of

wood, feed rate, and sandpaper grit. Under most sand-

ing conditions, the depth should not exceed ¹/64" (approx.

turn of the handwheel). Each full turn of the table

height handwheel raises the conveyor table approximately

0.020". Attempts to remove too much material can cause

jamming, wood burning, rapid paper wear or tearing,

poor finish and belt slippage.

To set the depth of cut, do these steps:

1. Rotate the table height handle (Figure 24) until the

table is too low, then raise the table, allowing a gap

between the workpiece and the sanding drum.

Note: When adjusting the table to sand a thicker

workpiece, lower and then raise the table to remove

backlash from the adjustment mechanism.

2. Start the conveyor and sanding drums and feed the

workpiece into the sander. SLOWLY raise the con-

veyor table until the workpiece makes light contact

with the sanding drums. This is the correct height to

begin sanding the workpiece.

Figure 24. Table height handwheel.

Variable Speed

The variable speed knob allows you to increase the feed

rate from 6–18 FPM. The correct speed to use depends on

the type of stock you are using (hardwood vs. softwood)

and the stage of finish you are at with that workpiece.

NOTICE

Adjusting the variable speed when the

conveyor motor is OFF can damage the

V-belt and the adjusting mechanism.

As a general rule, a slower feed rate will sand the surface

smoother, but runs the risk of burning the wood; a faster

feed rate will remove material faster, but runs the risk of

overloading the motor. Use trial-and-error to determine

the best settings for your specific applications.

To adjust the conveyor speed, do these steps:

1. Start the conveyor (DO NOT adjust conveyor speed

when the conveyor motor is OFF).

2. Rotate the variable speed knob (Figure 25) counter-

clockwise to increase the feed speed, or clockwise

to decrease the feed speed.

W1772/W1773 37" Drum Sander

Using the Amp Draw

Meter

The amp draw meter (Figure 26) is used to keep

the machine from being overloaded during sanding

operations.

As a general rule, always start with a shallow sand-

ing depth and carefully increase the sanding depth.

Keep the amp load in the green range during operation.

Generally, the normal depth of cut is no more than ¹⁄64"

or 0.016" for a 36¹/2" wide board using coarse sandpaper.

DO NOT work your machine in the red zone as shown on

the Amperage Load Chart. If operated in the red zone,

the motor will lose RPM, the start capacitor will ener-

gize, and capacitor or motor damage will occur.

Figure 26. Amp draw meter.

��

Amp load is directly affected by many factors such as

feed rate, depth of cut, wood type, sandpaper grit, and

workpiece width.

Sanding

��

To sand a workpiece, do these steps:

1. Adjust the table height according to the instructions

in Depth of Cut on Page 24.

Figure 28. W1773 amp load chart.

2. Start the dust collector, the drum motor, and the

feed motor.

Close all covers and panels before

starting the drum sander. Failure to

do so could result in severe personal

injury.

3. Feed the workpiece through the sander while stand-

ing to the side and monitor the amp meter; if it

approaches the maximum amp load, lower the con-

veyor table.

4. Run wide stock through two or three times with-

out adjusting the table height. Turn the stock 180°

between passes to ensure an even cut. Do not sand

more than one workpiece at a time side-by-side.

DO NOT sand more than one board at

a time side-by-side. Minor variations

in thickness can cause one board to

be propelled by the rapidly spinning

sanding drum and ejected from the

machine. NEVER stand directly in front

of the machine. Failure to do so could

result in severe personal injury.

Sanding Tips

•

Replace the sandpaper with a higher grit to achieve

a finer finish.

Raise the table with a maximum of ³/4 turn of the

height handle until the workpiece is the desired

thickness.

•

Reduce snipe when sanding more than one board of

the same thickness by feeding them into the sander

with the front end of the second board touching the

back end of the first board.

Feed boards into the sander at different points on

the conveyor to maximize sandpaper life and pre-

vent uneven conveyor belt wear.

•

Replace the sandpaper with a higher grit to achieve

a finer finish.

Raise the table with a maximum of ³/4 turn of the

height handle until the workpiece is the desired

thickness.

•

DO NOT sand boards less than 9" long or less than

¹/16" to prevent damage to the workpiece and the

drum sander.

•

Extend the life of the sandpaper by regularly using a

PRO-STICK® sanding pad (Page 29).

When sanding workpieces with irregular surfaces,

such as cabinet doors, take very light sanding passes

to prevent gouges. When the drum moves from sand-

ing a wide surface to sanding a narrow surface, the

load on the motor will be reduced, and the drum

will speed up, causing a gouge.

•

DO NOT edge sand boards. This can cause boards to

kickback, causing serious personal injury. Edge sand-

ing boards also can cause damage to the conveyor

belt and sandpaper.

•

When sanding workpieces with a bow or crown,

place the high point up (prevents the workpiece

from rocking) and take very light passes.

Feed the workpiece at an angle to maximize stock

removal and sandpaper effectiveness, but feed the

workpiece straight to reduce sandpaper grit scratch-

es for the finish passes.

The general rule of thumb is to sand a workpiece with

progressively higher grit numbers, with no one grit

increase of more than 50. Avoid skipping grits; the larger

the grit increase, the harder it will be to remove the

scratches from the previous grit.

into combinations of successive group types. A common

selection for stock that is planed before being sanded is a

100/150 grit combination.

Cleaning the Model W1772/W1773 is relatively easy. From

time to time, vacuum wood dust off of the internal compo-

nents, especially the motor.

Grease

Fitting

Lubrication

Moving parts, such as chains, should be lubricated peri-

odically with a light machine oil. Motor bearings need no

lubrication.

Pillow Bearing: Must be lubricated every 20 hours of

operation. Use a high-quality, lithium-based grease. A

grease fitting (Figure 32) is located on the top of each

pillow bearing. Give only one to two pumps of the grease

gun. Too much grease can pop seals out.

If this warning is ignored, serious

personal injury may occur.

The gauge blocks described here will be required to com-

plete most of the service procedures in this section. After

you have made them, they can be conveniently stored

inside of the sander cabinet for future use.

To make the gauge blocks, do these steps:

1. Edge joint the concave edge of a 7' long 2x4 flat on

a jointer, as shown in Figure 37.

2. Place the jointed edge of the 2x4 against the table

saw fence and rip cut just enough off the oppo-

site side to square up the two edges of the 2x4, as

shown in Figure 38.

Figure 37. Edge jointing on a jointer.

3. Using a miter saw or circular saw, cut 6" off each

end of the board to remove any portions with slight

snipe from jointing. Then cut the 2x4 into two even

pieces to make two 36" long wood gauge blocks.

V-Belt Service

Tension

New V-belts often stretch and loosen up during the first

16 hours of use. After this period, they should be inspect-

ed and re-tensioned if necessary.

OFF

Proper tension is important for optimum power transmis-

sion. However, too much tension may cause premature

bearing failure.

The correct V-belt tension is achieved when the V-belts

can be deflected ¹/2"–³/4" when pushed in the middle with

moderate pressure. See Figure 39 for an example of how

to perform a V-belt deflection test with a straightedge

and ruler.

4. Close the pulley cover and reinstall the handwheel.

Removal/Replacement

Replace the V-belt if you notice fraying, cracking, glaz-

ing, or any other damage. A worn/damaged V-belt will not

provide optimum power transmission from the motor to

the drums.

Figure 40. V-belt tension controls.

V-belt removal and replacement is simply a matter of

loosening the V-belts until you can roll them off the pul-

leys, replacing them with a MATCHED set, then re-ten-

sioning them.

Note: A matched set means both the V-belts are the same

size and also have the same serial number.

Pulley Alignment

Pulley alignment is another important factor in power

transmission and belt life. The pulleys should be parallel

to each other and in the same plane (coplaner) for opti-

mum performance.

Conveyor Tensioning &

Tracking

Tensioning

The conveyor may slightly stretch with continued use and

will eventually need to be tensioned. This is most obvious

if the conveyor starts slipping on the rollers.

When you tension the conveyor, focus on turning the

adjustment bolts in even increments. Tensioning one side

more than the other will cause tracking problems, which

will require you to take additional steps to get the sander

operating correctly.

Loose hair and clothing could get

caught in machinery and cause serious

personal injury. Keep loose clothing

rolled up and long hair tied up and

away from machinery.

To tension the conveyor, do these steps:

1. Using a 19mm wrench, loosen the lock nut (see

Figure 47) on both sides of the conveyor.

2. Measure the distance from the frame to the convey-

or roller on both sides. Turn the adjustment bolts so

the distance between the frame and conveyor roller

is identical on both sides. Do not overtighten the

conveyor. Your goal is to reach a ³/4" gap between

the underside of the conveyor and the belt, as

shown in Figure 48.

3. Use a magic marker, white out, or fingernail polish to

mark the front of the conveyor tensioning bolt on both

sides.

& tracking controls (guard removed for

clarity).

4. Turn both of the conveyor adjustment bolts clock-

wise one full turn at a time until the conveyor belt

no longer slips during operation.

— If the conveyor starts tracking to one side, imme-

diately turn the drum sander OFF and perform the

tracking instructions.

5. Tighten the lock nuts to lock the conveyor adjust-

ment bolts in place.

Tracking

If the conveyor tracks to either side, then the tracking

must be corrected or the conveyor will load up to one

side and could rip or tear and have to be replaced.

Replacing a damaged conveyor is a big job. Always be

careful to make sure that the belt does not travel too far

to one side or the other.

Tracking the conveyor is a balancing process that takes

patience and some trial-and-error. Usually you must tight-

en the loose side (the side the belt is tracking towards)

to make the conveyor move to the middle of the rollers,

then loosen that same side to make the conveyor stay in

position. If you adjust the bolt too much either way, then

you have to repeat the process until the conveyor rides in

the middle and stays there during continuous operation.

Loose hair and clothing could get

caught in machinery and cause serious

personal injury. Keep loose clothing

rolled up and long hair tied up and

away from machinery.

To track the conveyor, do these steps:

1. Make sure the drums are perpendicular to the feed

direction (parallel with the conveyor roller). Go to

Page 38.

2. Turn the conveyor ON and watch it track.

3. Determine which side the conveyor is tracking towards

(the loose side) and tension the adjustment bolt on

that side until the conveyor tracks in the opposite

direction. Note: Tracking changes may take up to

three minutes before they are noticeable.

4. When the conveyor is near the middle of the rollers or

table, loosen the adjustment bolt until the conveyor

stops moving and tracks straight.

— If the conveyor tracks too far to the other side,

then adjust the bolt as necessary to bring it back

and repeat Steps 2 & 3 until the tracking is cor-

rect.

Drum Adjustments

There are three adjustments for the sanding drums: 1) the

drums must be perpendicular to the feed direction (par-

allel with the conveyor roller, Figure 49); 2) the drums

must be parallel to the top of the conveyor belt (Figure

54, Page 40); 3) the rear drum must be set approximate-

ly 0.007" to 0.015" below the front drum (Figure 58, Page

41).

At some point, you may need to readjust the rear drum

parallel to the conveyor if you change the rear drum

height to accomodate for different sandpaper thicknesses

or finish requirements. Make sure the rear drum does not

sit lower than 0.015" below the front drum.

Adjusting Drums Perpendicular to Feed

Direction

��

��^��^��

�

The tolerances for having the drum perpendicular to the

feed direction allow up to ¹⁄8" difference from one side

to the other (see Figure 49). If the drums are not per-

pendicular to the feed direction (in other words, parallel

to the conveyor rollers), they may put a side load on the

conveyor belt during operation, forcing the conveyor to

track off to the side and possibly causing damage.

�

��

To adjust the drums perpendicular to the feed direc-

tion, do these steps:

��

�

1. DISCONNECT POWER TO THE SANDER!

��

2. Check to make sure the conveyor roller is parallel to

the machine frame, and make adjustments if need-

ed. (Refer to Page 36.)

��

3. Open the top and pulley covers and remove the V-

belts (refer to Page 33 for V-belt removal instruc-

tions).

Figure 49. Drum perpendicular to feed

direction.

4. Remove the sandpaper from the drums for best

results.

5. At both ends of the rear drum, measure the distance

between the edge of the rear drum and the rear

upper frame, as shown in Figure 50. The difference

between these two measurements will tell you how

close the drum is to being perpendicular to the feed

direction (assuming that the conveyor roller is paral-

lel to the machine frame).

edge of rear drum and the upper frame.

— If the difference between the two measurements

at each end are within ¹⁄8", skip to Step 8.

Adjusting Drum Height & Drum-to-Conveyor

Parallelism

��

The rear drum can be adjusted parallel to the conveyor

belt in fine increments at the pillow bearings with the

micro-adjust knobs, or the front drum can be adjusted

parallel to the conveyor with the set screws on the pillow

bearings. If, after performing the following procedure,

you cannot adjust the drums parallel to the conveyor belt,

it is possible that the conveyor table needs further adjust-

ment. In that case, follow instructions on Page 43 for

adjusting the table parallel to the drums at the table lift

screws.

��

�

��

�

��

Keep in mind that having the drums parallel to the top of

the conveyor belt (see Figure 54) is critical to the sand-

ing operation. Take care to adjust the drums parallel to

the conveyor surface within 0.002" from one side to the

other.

�

��

�

To adjust the rear drum height and adjust the drums

parallel to the conveyor belt, do these steps:

Figure 54. Drum parallel to conveyor belt.

1. DISCONNECT POWER TO THE SANDER!

2. Open the top and pulley covers, remove the V-belts,

and remove sandpaper from the drums for best

results.

3. Place the gauge blocks (refer Page 32) on the con-

veyor table and position them under the drums, as

shown in Figure 55.

Figure 55. Gauge blocks under drum

rollers.

4. Raise the table up until the gauge blocks are approxi-

mately 0.010" below the rear drum, checking with a

feeler gauge. This setting will be used to determine

rear drum-conveyor bed parallelism. Note: Each full

turn of the table height handwheel raises the conveyor

table approximately 0.020".

Pressure Roller Height

The pressure rollers are factory set at 0.039"–0.078" below

the bottom of the rear sanding drum and are fully adjust-

able either up/down with the lock nuts shown in Figure

59.

Proper pressure on the workpiece helps avoid kickback and

keeps the workpiece from slipping. However, as pressure

increases on the workpiece, snipe also increases (snipe is

normal with all brands of drum sanders).

If snipe becomes a problem, you can minimize it by reduc-

ing pressure (raising pressure roller height). However, you

can only minimize it so much before the workpiece will slip

or kick out, causing a hazard to the operator. If this hap-

pens, you have raised the pressure rollers too high for them

to function as intended—the pressure rollers MUST then be

lowered to prevent injury.

Figure 59. Pressure roller adjustment

nuts.

Note: An additional trick for eliminating snipe is to reduce

pressure on the rear rollers, but not the front rollers.

Conditions will vary with wood types, so use trial-and-error

to find the best results for your application.

These instructions will restore the pressure rollers to the

factory setting.

To adjust the pressure rollers to the factory setting, do

these steps:

1. DISCONNECT POWER TO THE SANDER!

2. Open the top cover.

3. Place the gauge blocks on the conveyor table and

position them under all the pressure rollers, as shown

in Figure 60.

4. Adjust the conveyor table up so the gauge blocks just

touch the bottom of the rear drum.

5. Rotate the handwheel eight full turns clockwise,

counting from the point of actual table movement so

handwheel freeplay does not affect your count.

6. With all the pressure rollers: 1) Raise one end off of

the gauge block, then move it back down until it just

touches the gauge block; 2) repeat with the other

side; 3) tighten the lock nuts together to make sure

the adjustments are locked in place.

adjusting the pressure roller height.

Scale Pointer Calibration

For the scale pointer to be accurate, it must be calibrat-

ed.

We recommend calibrating your scale pointer any time

you adjust the drum heights or table lift screws.

To calibrate the scale pointer, do these steps:

1. Sand a workpiece with the drum sander and measure

the thickness of the sanded workpiece.

Figure 61. Scale pointer screw.

2. Loosen the screw that secures the scale pointer and

adjust it to the thickness of the workpiece.

Dust Scoops

The dust scoops and metal scoop plates are correctly

positioned on the top cover at the factory, however these

may loosen and move during shipping. Some trial and

error will be needed to adjust the dust scoops so they do

not contact the sanding drums.

Dust Scoops

To adjust a dust scoop, do these steps:

Button Head

Cap Screw

1. DISCONNECT POWER TO THE SANDER!

2. Remove the handwheel and open the pulley cover.

Metal

Scoop

Plate

3. Loosen the button head cap screws and acorn

nuts securing a metal scoop plate to the top cover

(Figure 62), move the scoop up a little, tighten the

cap screws and nuts, close the top cover, and rotate

the V-belt to see if the drum srapes the scoop.

Figure 62. Location to adjust dust scoop.

4. Adjust each scoop in this manner until the sanding

drums do not scrape the scoops, then close the pul-

ley cover and reinstall the handwheel.

Table Lift Scews

The table lift screws are connected by a chain and driven

by the table elevation handwheel. When the chain is

removed from a sprocket on one of the lift screws, that

lift screw can adjust that portion of the table up/down

independently to assist in setting the table parallel to the

drums.

Adjusting the table lift screws will only be necessary if

you need to adjust the drum heights more than allowed

at the pillow bearing adjustments, or if you have removed

the table or chain during a service procedure and you

need to reset the drums parallel to the table.

W1772/W1773 37" Drum Sander

Each tooth on the sprocket represents 0.006" of table

elevation movement. For example, if the rear of the table

was 0.006" low, rotate both rear table lift screws to the

next sprocket tooth in the same chain position. You can

easily rotate the sprockets from the top of the table lift

screws with a flat head screwdriver.

After adjusting the table lift screws, check to make sure

the drums and conveyor are parallel within 0.002" from

one side to the other. If they are not within this range,

then additional fine adjustments should be made at the

drum pillow bearings.

To adjust the table lift screws, do these steps:

1. DISCONNECT POWER TO THE SANDER!

2. Open the side cover.

Figure 63. Marking sprocket tooth and

chain.

3. Raise the table up to at least the 1" mark on the

height scale.

4. At the lift screw that needs to be adjusted, mark the

end of a sprocket tooth and the chain hole where that

tooth is meshed, as shown in Figure 63.

5. Using two 14mm wrenches, loosen the adjustable

idler roller (Figure 64).

6. Carefully move the chain off of only the marked

sprocket.

Figure 64. Adjustable idler roller sprocket.

7. Keep track of the marked chain hole and rotate the

sprocket the necessary number of teeth away from

the marked one to meet the difference in height

needed.

8. Fit the chain back over the sprocket, making sure the

new sprocket tooth is inserted into the marked chain

hole.

9. Re-tension the chain and check the new height set-

ting.

10. Repeat Steps 5–9 as needed until the table height is

parallel to the drums in all four corners, and calibrate

the scale pointer (refer to Page 43).

11. Follow instructions in Drum Adjustments (Refer to

Page 38) for adjusting the drums parallel to the con-

veyor within 0.002" side-to-side.
