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

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.

Machine Placement

Cleaning Machine

•

Floor Load: This machine distributes a

heavy load in a small footprint. Some shop

floors may require additional bracing to

support both machine and operator.

The upper sanding drum on this machine is

coated with a waxy grease that protects it from

corrosion during shipment. Clean this grease off

with a solvent cleaner or citrus-based degreaser.

DO NOT use chlorine-based solvents such as

brake parts cleaner or acetone—if you happen to

splash some onto a painted surface, you will ruin

the finish.

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 wide-belt sander.

NEVER clean with gasoline

or other petroleum-based

low flash points, which

make them extremely

flammable. A risk of

explosion and burning

exists if these products

are used. Serious personal

injury may occur if this

warning is ignored!

Electrical: Electrical circuits must be

dedicated or large enough to handle

amperage requirements. Outlets must be

located near each machine, so power or

extension cords are clear of high-traffic

areas. Follow local electrical codes for

proper installation of new lighting, outlets,

or circuits.

•

Dust Collection: Place this machine as

close to your dust collector as possible to

eliminate long runs of large ducting and

improve dust collection from the machine.

Dust Collection

��

An efficient and clean dust collection system is essential

to the proper function of the sander. Ensuring a healthy

work environment is also dependent upon cleaning and

maintaining your dust collection system. We recommend

connecting this wide-belt sander to a cyclone dust

collector rather than a bag type dust collector, since

a cyclone will handle fine dust particles better and

experience fewer clogging problems.

Figure 9. Regulator knob.

Recommended CFM at Machine (W1756): 1500 CFM Min.

Recommended CFM at Machine (W1757): 2000 CFM Min.

Do not confuse this CFM recommendation with the rating

of the dust collector. To determine the CFM at the

machine, you must take into account many variables,

including 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.

Figure . Regulator knob.

DO NOT operate this machine with-

out an adequate dust collection sys-

tem. This machine creates substantial

amounts of wood dust while operating.

Failure to use a dust collection system

can result in short and long-term respi-

ratory illness.

To hook up a dust collection system, do these steps:

1. Install the dust ports (Figure 10) to the mounting

locations on the top of the sanding unit with the

supplied M6-1 x 10 Phillips head screws, or install a

wide-belt sander dust hood.

Hose Clamp

2. Using 4" hose clamps, secure the hoses from your

dust collection system to the dust ports (Figure 10).

Pressure Roller Height

The pressure rollers have been set at the factory, but to

ensure safety, you should verify that they are set below

the level of the sanding roller.

It is absolutely essential to keep the

pressure rollers set below the level

of the sanding roller. If the pressure

rollers are even with or higher than

the sanding roller, the wood may be

propelled from the sander at a high

rate of speed. This situation could

cause serious kick-back injury.

To check the pressure roller height, do these steps:

1. DISCONNECT THE SANDER FROM THE POWER SOURCE!

2. Place a piece of scrap wood of uniform thickness

across the table so it spans both the front and the

rear pressure rollers at the same time.

3. With the air pressure connected and the sanding belt

installed and tensioned, manually raise the table and

verify that the board touches both pressure rollers

before it touches the sanding belt.

Note: If the board does not touch both pressure

rollers before it touches the sanding belt, then the

pressure rollers must be adjusted before operation.

See Pressure Rollers on Page 39 for step-by-step

instructions.

Breather Pin

The Model W1756/W1757 has a breather sealing pin

installed in the fill plug for the feed belt gear reducer.

Remove this pin before using your sander (see Figure 13);

otherwise, the gear oil will expand with heat and the

seals in the gear reducer may leak due to the pressure

build up.

You may want to retain this pin if you plan on storing your

sander for a long period of time.

Test Run

Once the assembly is complete, test run your machine

to make sure it runs properly and is ready for regular

operation.

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

motor powers up and runs correctly, 2) the stop button

safety feature works correctly, and 3) the feed belt motor

turns the correct direction.

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.

If, during the test run, you cannot easily locate the source

of an unusual noise or vibration, stop using the machine

immediately, then review Troubleshooting on Page 55.

W1756/W1757 43" Wide-Belt Sander

General

This sander will perform many types of operations that

are beyond the scope of this manual. Many of these

operations can be dangerous or deadly if performed

incorrectly. This sander is only designed to sand wood—

not metal, fiberglass, or plastics.

The instructions in this section are written with the

understanding 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!

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!

If you are an inexperienced operator, we strongly

recommend that you read books, trade articles, or seek

training from an experienced wide-belt sander operator

before performing any unfamiliar operations. Above all,

your safety should come first!

Setting Feed Speed

The dial attached to the side of the feed belt motor

cover (Figure 17) adjusts the feed rate of the sander.

To change the feed belt speed, do these steps:

Always wear safety glasses and a

respiratorwhenoperatingthismachine.

Failure to comply may result in serious

personal injury, allergic reactions, or

respiratory problems.

1. Start the feed belt.

2. Turn the dial clockwise to decrease the feed rate

and counterclockwise to increase it.

Note: Never adjust the feed rate dial unless the

feed belt is running, otherwise you can damage the

control.

Determining Ideal Feed Rates

Softwoods typically require a faster feed rate than

hardwoods; however, there is no definitive rule to follow

when determining the best feed rate. As a general rule,

always start with the slowest feed rate and work your

way up. We always recommend testing the feed rate

using scrap wood similar to your workpiece. Be sure

to monitor the amperage meter (see Page 25) when

adjusting the feed rate. Decrease the feed rate if the

load begins to slow the motor RPM.

Figure 17. Variable feed rate dial.

Choosing Sandpaper

When selecting sandpaper, keep in mind that the Model

W1756/W1757 accepts only 43" wide by 60" long belts.

The grit you choose will depend on the type of work, the

species of wood and the stage of finishing. When choosing

which sandpaper to use, use these grit numbers as a

general guide to sandpaper type:

Grit

Type

60 or less..................................................Coarse

80-100 .................................................. Medium

120-150.......................................................Fine

We recommend using aluminum oxide sanding belts for

the best results. The general rule of thumb is to sand a

workpiece with progressively higher grit numbers, with

no one grit increase of more than 50; however, the type

of wood and desired finish will determine the best grit to

use.

Note: When used on wide-belt sanders, sandpaper finer

than 150 grit will often be problematic and load up or

burn workpieces.

Amp Draw Meter

The amperage draw meter (Figure 18) is used to keep

the machine from being overloaded during sanding

operations.

As a general rule, always start with a small load and work

your way up. DO NOT work your machine to its maximum

load, or where you can hear the motor lose RPM; instead,

make multiple passes or install a coarser grit sandpaper.

Amp load will be directly affected by many factors such

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

and workpiece width. If the amp load is in the red load

range, the machine is overloaded and motor damage may

soon occur. Use the amp load chart on the meter to keep

the amp load in the green range during operation.

Figure 18. Amp draw meter.

NOTICE

DO NOT VOID MACHINE WARRANTY!

Keep the amp draw within the GREEN

zone shown on the AMP LOAD CHART.

If you operate the sander in the RED

zone, motor damage may occur and

will not be covered under warranty.

19, stops the electricity to the motors and also applies an

air-disc brake to stop the sander immediately.

To use the emergency stop plate, push and hold it until

the sander has come to a complete stop.

KEEP the sanding drum V-belts correctly tensioned

(refer to Page 41). Otherwise, the sanding drum

pulley will slip when the emergency brake is applied

and not immediately stop the machine in the event

of an emergency!

Sanding Workpiece

To achieve the best sanding results experiment with

conveyor feed rate, sanding depth, various grits of

sandpaper, and oscillation speed. Also, make sure the

workpiece has been jointed and planed before sanding.

Tip

For best results when finish sanding,

feed each piece through the sander

two or three times without adjusting

the depth of cut. Turn the workpiece

180˚ and feed it through two or three

more times at this same depth. As

always, use your best judgement. If

you no longer hear the sanding belt

making contact with the workpiece

on successive cuts, then no further

passes are needed at that depth.

Typically, no more than 0.5mm (approx. ¹⁄64") of material

is removed during each pass. Attempts to remove too

much material can cause jamming, wood burning, rapid

sandpaper wear or tearing, poor finish, short motor life,

and belt slippage.

To sand a workpiece, do these steps:

1. Measure the workpiece and record the thickest spot.

2. Put on safety glasses, a dust mask, and hearing

protection!

3. Make sure the sander is connected to power and

compressed air and turn ON the dust collector and

the sander.

4. Raise the table to the thickness of the workpiece

and make an initial pass to eliminate any high spots.

5. Continue to raise the table 0.0625" between each

successive pass until the sander begins to sand the

entire workpiece.

6. Type in the thickness of your workpiece using the

numeric key pad (Example: for a 2" thick workpiece

type 2.000"), and press the table start key. Note:

The upper left corner Input LED will illuminate (See

Figure 20), and the display numbers will flash when

entering measurements.

7. Measure the sanding depth needed. Example: let’s

say you need ¹⁄64 ".

8. Convert ¹⁄64" fraction to a 0.016" decimal

measurement using the conversion table on the

sander.

9. Calculate the resulting workpiece thickness (2.000"—

0.016" = 1.984"), and type that thickness (1.984") on

the key pad.

10. Press the table start key: The table will raise to the

new setting. Note: The computer rounds the sanding

thickness measurements in increments of 0.005",

and if you want to move the table up in 0.005"

increments, just tap the up arrow. The same holds

true for the down button.

Note: The lower left corner Run LED will illuminate

and the display numbers will glow steadily when

measurements have been accepted and the table is

auto-adjusting. When the correct sanding depth is

achieved, the lower left corner Run LED will turn

off and the final resulting workpiece thickness is

displayed.

11. Start the feed belt, stand to the side as shown in

Figure 21, and feed the workpiece into the sander.

12. Observe the amp draw meter, and press the table

down arrow key on the key pad to reduce the

sanding depth if the amp load meter indicates motor

overload, or reduce the feed rate.

13. Remove the workpiece from the outfeed side, which

is now sanded down ¹⁄64". Re-sand the workpiece

a couple of times more at this depth to ensure a

consistent sanding depth.

Figure 21. Operator feeding workpiece at

correct body position and out of the way

of potential kickback.

14. Add a new sanding depth the same way as in Steps 9

and 10, and sand again.

Platen Adjustment

Your sander is equipped with an adjustable felt platen and

graphite slip for those extra sensitive sanding operations.

The platen position allows for three basic types of

sanding. These different positions can be adjusted by

rotating the height lever shown in Figure 22.

Height

Scale and

Lever

Pointer

The three basic platen positions:

Lock

Lever

Platen Up: The platen is raised above the level of the

sanding rollers. This position allows the front roller to

remove large amounts of material quickly, but leaves a

rough finish. The best belt grit for this position is #100 or

coarser.

Platen Even: The platen is set even with the sanding

rollers. The rollers work together with the platen to

produce intermediate/final finishing. The best belt grit for

this position is #100-#150.

Figure 22. Platen controls.

Platen Down: The platen is lowered below the sanding

rollers. The majority of the work is accomplished by the

platen pressure on the workpiece. The result is a smooth,

flat finish. The best belt grit for this position is #150.

Avoid lowering the platen more than 0.2 mm below the

sanding belt rollers, or you will prematurely wear the

platen.

Note: The platen scale is in millimeter increments.

MAINTENANCE

General

Regular periodic maintenance on your machine will ensure

its optimum performance. Make a habit of inspecting your

machine each time you use it.

Check for the following conditions and repair or

replace when necessary:

•

Loose mounting bolts.

Damaged sanding belt.

Worn or damaged wires.

Water collection cups filled with water.

Dust trap.

Safety features.

Any other condition that could hamper the safe

operation of this machine.

OFF

Makesurethatyourmachineisunplugged

during all maintenance procedures! If

this warning is ignored, serious personal

injury may occur.

Lubrication

Wipe off all sawdust and abrasives from grease fittings

and plugs before lubrication. When lubricating machine

parts, your goal is to achieve adequate lubrication to

prevent rust, and a thin layer of lubricant to prevent

metal-to-metal friction. Too much lubrication will attract

dirt and sawdust, causing machine parts to bind.

Grease

Fittings

Lubricate the following areas according to frequency of

use:

Weekly. Give one or two pumps of a multi-purpose

automotive grease to the grease fittings (Figure 23 & 24)

located on the feed belt roller axles and the sanding belt

roller axles. They are identified with yellow labels.

Cleaning Sanding Belts

To increase the working life of your sanding belts, clean

them whenever they decrease in performance due to

heavy loading. Use a Model D3003 Pro-Stik^®Cleaning Pad

as shown in Figure 28.

To clean the belts, simply set your table to the thickness

of the cleaning pad, and run the pad through the sander

two or three times. DO NOT take too deep of a cut—

the belt should barely touch the cleaning pad!

Air System

The air system is durable and reliable; however,

components do wear with age. If you suspect that an item

in your air system may be having problems, see the Air

System Diagram on Page 48 for troubleshooting locations.

If a component in the air system is

malfunctioning, bleed all air from the

system, and fix the problem before

you resume sanding.

Verify or set the following:

•

Adjust regulator to 75 PSI.

Carefully inspect all air lines for cracks, pinches, or

hardening. Replace faulty hoses.

•

Check the air connections for leaks. A small amount

of soapy water in a questionable area will bubble if

there is a leak.

Make sure lines are not clogged. Remove a

questionable line and blow through it as a test.

Dust and Water Traps

Three collection traps on this wide-belt sander need to

be emptied when they become half full. One water trap

is attached to the bottom of the air regulator, and two

dust traps are attached on the air diaphragm assemblies.

DO NOT allow the water trap and dust bowls to become

full.

MAKE SURE that your machine is

unplugged during all service proce-

dures! If this warning is ignored, seri-

ous personal injury may occur.

Table Calibration

Feed a test board through the sander and measure it in

many locations on both sides along the length to test the

accuracy of the digital thickness gauge.

To calibrate the digital thickness scale, do these steps:

1. Using a properly set-up planer, plane a board to

uniform thickness.

2. Adjust the sander table far enough to place the

planed board under the sander roller.

3. Using the handwheel, manually raise the table until

the board just touches the sandpaper.

4. Remove the board without changing the table

height. This ensures the table will be properly

adjusted for the first sanding pass.

5. Run the board through the sander several times at

the initial height setting. Manually raise the table

0.020" and pass the board through the sander several

more times. Monitor the amperage meter and the

resulting load on the sander.

6. Measure the thickness at various points around the

board using a precise micrometer or set of calipers.

7. Continue sanding the board at that height until the

average thickness measurement is within ⁺⁄- 0.003".

Note: These final passes should be done without

adjusting the table height. This ensures the most

consistent average thickness.

8. Observe the digital display read-out, it should

indicate the average thickness of the sanded wood.

— If it does, the sander is properly calibrated and

accurate to the nearest 0.005".

— If it does not, you must recalibrate the digital

thickness scale.

To recalibrate the digital thickness scale, do these

steps:

1. Without moving the table height, enter the

numerical measurement of the average thickness

of the sanded wood into the digital key pad on the

control panel.

Note: The average thickness of the sanded wood

should now be flashing on the digital read-out.

2. Press and hold the SET key until the display stops

flashing. The sander is now correctly calibrated.

Oscillation Timing

NOTICE

When the oscillation is correctly adjusted, the sanding

belt oscillates to the left and to the right at the same

speed. If the sanding belt makes contact with a limit

switch, as shown in Figure 34, the emergency braking

system will activate and stop the sander immediately.

The oscillation adjustments have been

performed at the factory and should

require no further attention. However,

we recommend verifying the settings.

To check the sanding belt oscillation, do these steps:

the roller should pivot back to the left.

8. Reinstall the sanding belt.

9. Test the oscillation by running the sander. Make note

of the time it takes for the belt to oscillate from

left-to-right and from right-to-left.

When correctly timed, the oscillation should take a

similar amount of time to oscillate from side-to-side.

Figure 37. Oscillation adjustment knobs.

— If the oscillation time to the right is 2 seconds,

but the oscillation time to the left is longer,

loosen the oscillation adjustment knob (Figure 37)

and move it to the left (counterclockwise) until

proper tracking is achieved. Tighten down the

oscillation adjustment knob when satisfied.

— If the oscillation time to the left is 2 seconds, but

the oscillation time to the right is longer, loosen

Tighten the oscillation adjustment knob when

satisfied.

10. Continue to the next page to adjust the oscillation

speed.

Oscillation Speed

Lock Nut

The oscillation speed of the sanding belt is adjustable.

Different oscillating speeds yield different sanding results.

We recommend trying various speeds on a scrap piece of

wood similar to the final workpiece.

To adjust the oscillation speed, do these steps:

1. Loosen the lock nut on the speed control adjustment

knob (Figure 38).

Table Parallelism

The corners of the table can be independently adjusted

up or down. By disconnecting the chain and turning the

pertinent table elevation screw sprocket (Figure 39),

table parallelism can be achieved.

NOTICE

The table has been adjusted at the

factory and should require no further

attention. However, we recommend

verifying that it is parallel with the

sanding roller.

Adjusting the table parallelism can be a very tedious task

that takes a great amount of patience. DO NOT adjust the

table unless you have trouble sanding your workpiece to a

uniform thickness.

If a table adjustment is needed, take precise notes on the

positioning of the table elevation screws. This will allow

the original setting to be re-established.

To adjust the table parallelism, do these steps:

Elevation Screw

Sprockets

1. Pass a 43" wide board through the sander until the

entire surface of the board is making contact with

the sanding belt.

2. Measure the thickness of the board at various points

around the edge.

3. If there is a variation of thickness, the table can be

adjusted accordingly.

— For minor adjustment, loosen the table mounting

bolts, shown in Figure 40, and rotate the

elevation screw flange.

NOTICE

When adjusting the left front elevation

screw, make the same adjustment to

the left rear elevation screw. This

ensures the height from the front to the

back of the table remains unchanged.

Do the same when adjusting the right

elevation screws.

Pressure Rollers

To adjust the pressure rollers, do these steps:

NOTICE

1. DISCONNECT THE SANDER FROM THE POWER SOURCE!

The pressure rollers has been adjusted

at the factory and should require

no further attention. However, we

recommend verifying that they are

parallel with each other, the sanding

drum, and the feed belt table surface.

2. Plane a 6' long 2x4 to a uniform thickness and cut

it in half. Place one board along the length of the

feed belt on the right-hand side and place the other

board on the left-hand side.

3. With the sanding belt tensioned (Figure 41), move

the sanding rollers by hand and manually raise the

table until you hear the sandpaper just contact the

surface of the wood. DO NOT continue to raise the

table beyond that point.

of the product within two years, and provides Woodstock International, Inc. reasonable opportunity to

verify the alleged defect through inspection. If it is determined there is no defect, or that the defect

resulted from causes not within the scope of Woodstock International Inc.'s warranty, then the original

owner must bear the cost of storing and returning the product.

This is Woodstock International, Inc.'s sole written warranty and any and all warranties that may be

implied by law, including any merchantability or fitness, for any particular purpose, are hereby lim-

ited to the duration of this written warranty. We do not warrant that Shop Fox machinery complies
