9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi-
tion. Conductor size should be in accor-
dance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause
a drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace exten-
sion cords if they become damaged.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubri-
cating and changing accessories.
15. DISCONNECT TOOLS before servicing
and changing accessories, such as blades,
bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTION-
AL STARTING. Make sure switch is in off
position before plugging in. Also, the mag-
netic switch on this machine may start if the

SECTION 2: CIRCUIT REQUIREMENTS
220V Single-Phase
Grounding
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur-
rent. This tool is equipped with an electric cord
that has an equipment-grounding conductor
which must be properly connected to a grounding
plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
The Model G1066/G1066Z/G1079 features 220V
single-phase motors. The G1066/G1066Z 5 HP
motor will safely draw about 25 amps under load.
The G1079 2 HP drum motor requires 12 amps
for safe operation. All sanders feature 1/4 HP feed
motors that draw approx. 3 amps under load.
The Model G1066/G1066Z should be fused at 30
amps. The Model G1079 should be fused at 15
amps. Make sure the wiring in your circuit is rated
to handle the amperage draw from your machine.
If frequent circuit failure occurs when using the
sander, contact our Service Department. The
sander must be connected to its own dedicated
circuit and should not share a circuit with any
other machine. A standard 2-pole breaker is nec-
essary for use with the sander.
Improper connections of the electrical-grounding
conductor can result in the risk of electric shock.
The conductor with green or green and yellow
striped insulation is the electrical-grounding con-
ductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the
equipment grounding conductor to a live terminal.
We recommend using a NEMA-style L6-30 plug
and outlet for the Model G1066/G1066Z, and an
L6-15 for the Model G1079. You may also “hard-
wire” the sander directly to your panel, provided
you place a disconnect near the machine. Check
the electrical codes in your area for specifics on
wiring requirements.
This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no cir-
cumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.

Extension Cords
Wiring Diagram
The Model G1066/G1066Z/G1079 comes pre-
wired for 220 volt operation. Wiring diagrams are
provided at the back of this manual should it be
necessary to repair or revise the wiring. Always
consult a qualified electrician when doing any
electrical work on this equipment.
We do not recommend the use of extension
cords on 220V equipment. It is much better to
arrange the placement of your equipment and the
installed wiring to eliminate the need for exten-
sion cords. Should it be necessary to use an
extension make sure the cord is rated Hard
Service (grade S) or better. Refer to the chart in
Section 1: Safety to determine the minimum
gauge for the extension cord. The extension cord
must also contain a ground wire and plug pin.
Always repair or replace extension cords when
they become worn or damaged.
We have covered some basic electrical
requirements for the safe operation of your
Sander. These requirements are not neces-
sarily comprehensive. You must be sure
that your particular electrical configuration
complies with local and state codes.
Ensure compliance by checking with your
local municipality or a licensed electrician.

Clean Up
Site Considerations
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship-
ment. Remove this protective coating with a sol-
vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. Avoid chlo-
rine-based solvents as they may damage painted
surfaces should they come in contact. Always fol-
low the manufacturer’s instructions when using
any type of cleaning product.
FLOOR LOAD
Your new drum sander represents a large weight
load in a moderate sized footprint. Most shop
floors will be adequate for the weight of the drum
sander; however, some floors may require addi-
tional support. Contact an architect or structural
engineer if you have any question about the abil-
ity of your floor to handle the weight.
WORKING CLEARANCES
Working clearances can be thought of as the dis-
tances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands and/or work tables. Also consider the rel-
ative position of each machine to one another for
efficient material handling. Be sure to allow your-
self sufficient room to safely run your machines in
any foreseeable operation.
Do not use gasoline or
other petroleum-based
solvents to clean with.
They have 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.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or exten-
sion cords are not obstructing high-traffic areas.
Be sure to observe local electrical codes for prop-
er installation of new lighting, outlets or circuits.
Do not smoke while using
solvents. A risk of explo-
sion or fire exists and may
result in serious personal
injury.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Always work in well-
ventilated areas far from
potential ignition sources
when dealing with sol-
vents. Use care when dis-
posing of waste rags and
towels to be sure they do
not create fire or environ-
mental hazards.
Make your shop “child safe.”
Ensure that your workplace
is inaccessible to children by
closing and locking all
entrances when you are
away. Never allow visitors in
your shop when assembling,
adjusting or operating equip-
ment.

Sander to function properly, the sanding drums
must be aligned in two directions: (1) perpendic-
ular to feed direction (Figures 5 and 6) and (2)
parallel to the conveyor belt.

3. Tighten the lock nuts and recheck the align-
ment using the same hardwood block.
Tightening the lock nuts will pull the drum
downward slightly. Be sure to adjust to com-
pensate for this movement. Do not over
tighten the lock nuts. The bearing blocks
can break if over tightened.
3. Repeat the measurements with the rear
drum and brace. If the measurements are
1
not within ⁄8", the drums can be moved by
loosening the lock nuts on the bearing blocks
and moving one end of the drum forward or
backward as necessary in the slotted holes.
If the drums are not perpendicular to feed
direction, the sandpaper will creep toward
one end of the drum. After you have adjust-
ed the drums, do not forget to tighten the
lock nuts and recheck the alignment.
4. For Models G1066/G1079 repeat steps 1-3
for the other drum. Tighten the lock nuts.
Model G1066Z has micro-adjustment knobs
on the sides of the machine for rear drum
adjustments. See Figure 9. Both drums
should now be properly adjusted. Do not
change the table height until the lock nuts
are tight.
To adjust the drums parallel to the conveyor
belt:
1. Disconnect the sander from the power
source!
Use care when tightening lock nuts. While
they are made of durable cast metal, the
bearing blocks are susceptible to breakage if
the metal is fatigued by excess tension
caused by overtightening.
2. For this step, you will need a 24" long block
of wood. A quality 2x4 will work fine (See
Figure 10).
Micro-Adjust Lock Knob
Figure 10. Dimensions of gauge block.
3. Start with the front sanding drum. Lower the
table so the block will slide easily under the
pressure bars. Slide the block over to one
side of the table, with the front edge lined up
to the front of the table. (It is important to line
up the block carefully to ensure that the
same part of the 2x4 is used to set the drum
heights.) Raise the table up so the board
barely touches the front pressure roller.
Micro-Adjustment Knob

adjustment control.
To adjust the drums perpendicular to the feed
direction:
1. Disconnect the sander from the power
source!
4. Raise the table one full turn of the hand-
wheel. Adjust the height of that side of the
front sanding drum so it just touches the
board and is able to rock back and forth with
moderate resistance.
2. First measure the distance between the out-
side of the front drum and the inside of the
front brace. The distances should be within
1
⁄8" of each other at each end of the drum.

5. Stop and mark the location of the table ele-
vation handle with a felt pen or piece of tape.
In the same manner, mark the height of the
table in relation to the body of the sander.
Both of these marks will indicate this exact
table position (we will refer to it as reference
height #1). Having reference height #1
marked is crucial to all subsequent steps.
9. Repeat steps 5-6 until both sides of the rear
drum are the same. (Note: the G1066Z has
external height adjustment knobs for the rear
drum. These are located on each side of the
machine. Other than this difference, the pro-
cedure for setting the drum height is the
same.)
10. While the rear drum should always be slight-
ly lower than the front drum, the actual differ-
ence will vary depending on wood type, feed
rate, sandpaper grits, etc. Once you are
familiar and comfortable with the adjustment
procedures, you should experiment to arrive
at the best settings for your specific applica-
tion.
6. Lower the table exactly 2 turns. Remove the
block and re-insert it on the other side, taking
care to line it up with the front of the table just
as it was on the previous side. Raise the
table exactly 2 turns to bring it back up to ref-
erence height #1.
7. Set the height of that end of the drum to the
board. Rock the drum back and forth again.
It should feel and sound the same as it did on
the other end. If the sound and rolling action
are not identical, adjust the bearing block
height. Continue this procedure, going back
and forth, until both sides of the drum sound
and feel the same.
In addition to premature wear and failure of
sandpaper, improper drum alignment could
cause the possibility of an uncontrolled exit
of material from the machine—which could
result in damage to property or potential
operator injury.
8. To adjust the rear drum, lower the table by
turning the handwheel counter-clockwise
1
/8th of a turn from reference #1. Make a sec-
ond mark. This will be reference #2 and will
be used for setting up the rear drums.

To provide increased operator control, the Model
G1066Z features height adjustment controls for
the feed roller. These controls are located on the
underside of the roller pressure spring controls
and consist of a hex bolt and jamnut setup, exact-
ly like the roller pressure spring tension controls.
Pressure Rollers
The spring tension of the pressure rollers can be
adjusted to reduce snipe. (Note: roller pressure is
also affected by the drum height.)
To adjust the pressure roller height on the
Model G1066Z:

3. Loosen the jamnuts on the hex bolts. Turn
the hex bolts downward to increase the pres-
sure roller spring tension. See Figure 11.
Increasing the tension will increase the pres-
sure of the board on the conveyor belt, but
will also be less forgiving of irregularities in
the board and could cause jamming. You will
need to determine experimentally the optimal
tension for your stock.

Dust Scoop
V-Belt
The Model G1066/G1079 is equipped with a dust
scoop located next to the rear sanding drum. The
Model G1066Z features a dust scoop for each
drum. Dust scoops reduce the amount of dust
that accumulates on the workpiece as it travels
through the sander. Dust scoops are adjustable
and should be set approximately ⁄32'' above the
bottom of the rear drum for optimum effective-
ness.
The sanding drums are driven by two V-Belts on
the Models G1066 & G1066Z and one V-Belt on
the Model G1079. The V-Belts must have proper
tension for proper power transmission. Proper
tension is achieved when the V-Belts can be
deflected about 3⁄4" with moderate finger pressure
at the midpoint between the drum sheaves
(sheaves are integral on the Model G1079) and
the motor sheave. To adjust V-Belt tension,
loosen the motor mounting bolts and slide the
motor accordingly. Ensure that the pulleys stay in
line with each other and tighten the motor mount-
ing bolts. Re-check V-Belt tension and alignment.
1
To adjust a dust scoop:
1. Unplug the sander from its power source!
2. Place two 2x4’s of equal height under the
rear sanding drum and the dust scoop. Raise
the table until the 2x4’s just touch the drum.
To check alignment, ensure that the machine is
on a level floor. Hold a straightedge against the
side of the rear contact drum sheave. The contact
drum and motor sheaves are in alignment when
the straightedge also barely touches the side of
the motor sheave.
3. Loosen the dust scoop mounting bolts locat-
ed at each end of the scoop as shown in
Figure 12.
To align the sheaves, loosen the motor from the
motor mounting plate and shift the motor in the
desired direction. Tighten the motor mount bolts
and re-check alignment and tension.
4. Move the scoop up or down until it is approx-
imately 1⁄32'' above the 2x4’s. Some flexing of
the sheet metal assembly may be needed to
get the proper clearance. Retighten the
mounting bolts and remove the 2x4’s.
If the sheaves will not come into alignment by
adjusting the motor, the motor sheave can be
moved directly along the motor shaft. Loosen the
setscrew on the motor sheave and move it in or
out accordingly.
Dust Scoop
Mounting Bolt
Always inspect V-belts for damage or deteri-
oration when adjusting for tension or align-
ment. Should you find evidence of cracking,
abrasion or damage from wood chips or
other foreign materials, replace the belt
immediately. Belt breakage could lead to
mechanical damage or operator injury.

4. Unwind the old sandpaper and use it as a
pattern or use the pattern in Figure 14 to cut
a piece of 6" wide sandpaper of the desired
grit. It is necessary to cut a triangular portion
of the paper away at each end.
Paper Replacement
G1066/G1079
The Model G1066/G1079 is designed for 6" wide
sandpaper rolls. The outfeed sanding drum is
wrapped in felt to slightly increase the drum diam-
eter and to provide a smooth sanded surface.
The felt should be 1" from the edge of the drum
to allow room for the tape to adhere.
To change the paper:
1. Disconnect the machine from the power!
2. Take the sheet metal cover off.
3. Remove the tape from around the right side
of the drum and the clip that attaches the
sandpaper to the left side of the drum (See
Figure 13).
Figure 14. Illustrates paper preparation.
5. Starting at the left side of the drum, fold the
corner of the sandpaper into the spring clip,
then install the clip onto the tensioner. You
may need to tap the clip with a hammer or
mallet to ensure that it is seated; however,
you do not have to drive clip completely on,
just make sure it is secure. Too much force
will break the clip! Also, do not fold paper
over tensioner and then install the clip—the
paper may tear as a result.
Be careful that the tension wheel does not
pinch your fingers when the pressure is
released and it snaps back to a relaxed posi-
tion.
Tension Wheel
6. Pull the paper until the tension wheel spring
has bottomed out in its travel.
7. This step is possible to accomplish alone, but
it is easier with an assistant. While one per-
son rolls the drum, the other tightly spirals
the paper onto the drum, ensuring that there
are no bubbles or overlapping edges.
IMPORTANT: Try to leave a uniform 3⁄16" gap
between the spirals as you wind the paper
around the drum. This will allow the paper to
move and stretch slightly and will decrease
the likelihood of tearing and overlapping.

Important Tips For Changing Sandpaper
1. Disconnect the sander from the power
source!
•
Replace the paper on each drum individual-
ly. Once paper is removed from both drums,
they can be slippery and hard to rotate.
2. Remove the top cover to expose the drums.
3. One drum at a time, unwind the old sandpa-
per and notice the direction that it was
wrapped around the drum.
•
•
•
Always fold the paper into the spring clip and
then insert it.
The spring clip does not have to be driven
completely on.
4. Use the old sandpaper as a pattern to cut out
the new sandpaper.
Changing sandpaper is easier with the help
of another person.
5. Wrap the sanding drum with the new sand-
paper. Make sure to wrap the sandpaper
tight and try to keep the gaps to a minimum.
6. Tape both ends with 3⁄4" strapping tape, mak-
ing at least two complete passes so that the
second layer is directly on top of the first.
See Figure 15. Repeat steps 3-5 with the
other drum.

Dust Collection
DO
NOT
operate
the
Model
G1066/G1066Z/G1079 without an adequate
dust collection system. This machine creates
substantial amounts of wood dust while in
operation. Failure to use a dust collection
system can result in short and long-term res-
piratory illness.
The dust collection ports are located on the top of
the sanding head cover and each measures 4" in
diameter. It will be necessary to attach 4" dust
collection pipes over these ports. Flex-hose is
recommended because it will ease removal of the
sanding head cover when paper changes and
adjustments are necessary. Grizzly offers 4" flex-
hose to connect this machine to a dust collection
system. The flex-hose easily attaches with a 4"
hose clamp. Please refer to our catalog for cur-
rent price and ordering information.
Always wear a dust mask
in addition to using a
dust collector. Dust
masks filter out the
smaller particles of dust
that dust collectors can-
not trap.
Your dust collector must be able to move 450
cfm at the Drum Sander. If you have a remotely
located dust collector or you are operating more
than one machine at a time, ensure that your dust
collector has the capacity and power to meet this
requirement. A fine layer of dust will be present
on your stock as it comes out of the sander. This
is normal.

2. If the conveyor belt tracks toward the right
side, turn the adjustment bolt located at the
infeed right corner. Turning this bolt counter-
clockwise will make the sanding belt move to
the left.
Conveyor Belt
The conveyor belt tension and tracking adjust-
ments are controlled by the adjustment bolts
located at each end of the front and rear convey-
or rollers. If the conveyor belt is too loose or
tracks off to one side, adjust as follows:
3. After you have made the adjustment, run the
machine for approximately 15 minutes to
observe the tracking adjustment you made.
Be patient, the belt tracks slow.
1. If the conveyor belt is slipping, turn both
infeed adjustment bolts counter-clockwise.
See Figure 16.
4. If the conveyor belt tracks too far to the left,
loosen the adjustment bolt. Turning this bolt
clockwise will move the sanding belt to the
right.

The main power switch features an important
safety device that is very important to remember.
A twist-and-pull design in the knob helps to avoid
accidental starts; yet, in the event of an emer-
gency, the knob can be pushed straight down to
stop the machine.
NOTICE
Another important point to remember about the
control panel is that the feed conveyor motor and
the drum motor operate independently from each
other.
The following section was designed to give
instructions on the basic operations of this
drum sander. However, it is in no way com-
prehensive of every drum sander applica-
tion. WE STRONGLY RECOMMEND that you
read books, trade magazines, or get formal
training to maximize the potential of your
drum sander.
The load meter and the variable speed dial are
very important to the operation of the Model
G1066Z. Please read the “Load Meter” and the
“Variable Speed” instructions in this section
before sanding any stock.

Test Run
G1066/G1079
Once the assembly is complete and the adjust-
ments are done to your satisfaction, you are
ready to test the machine.
Your new Model G1066/G1079 Drum Sander is a
relatively simple piece of equipment to set up and
run. Under most sanding conditions, a normal cut
is no more than 1⁄64". This depth can be achieved
Turn on the power supply at the main panel.
Press the START button. Make sure that your fin-
ger is poised on the STOP button, just in case
there is a problem. The drum sander should run
smoothly, with little or no vibration or rubbing
noises. Strange or unnatural noises should be
investigated and corrected before operating the
machine further. To avoid injury or damage to the
machine, DO NOT attempt to make adjustments
to the machine without turning it off and unplug-
ging it from its power source.
1
by approximately ⁄4 turn of the table height han-
dle. Attempts to remove too much can cause jam-
ming, wood burning, rapid paper wear or tearing,
poor finish and belt slippage. We recommend that
wide stock be sent through two to three times
without adjusting the table height. Turn the stock
180° to ensure an even cut. The following is the
correct start-up and operating procedure for
either of these machines.
1. Start the dust collector.
If noises occur that cannot be found by visual
inspection, feel free to contact our Service
Department for help.
2. Make thickness adjustment. Place workpiece
on the conveyor table and turn the table han-
dle until the workpiece can be sanded and
fed through smoothly. Turning the handle
clockwise will raise the conveyor table.
Turning the table handle counter-clockwise
will lower the conveyor table.
DO NOT attempt to investigate or adjust any
features of the machine while it is running.
Wait until the machine is turned off,
unplugged and all working parts have come
to a rest before you do anything! Failure to
do so could result in severe injury or dam-
age to equipment.
3. Remove the workpiece from the conveyor
belt.
4. Start the Drum Sander and feed your stock.
Retrieve by standing at the side–not at the
outfeed end.
5. Check the sanded piece. Is the piece
smooth? Mark a squiggly pencil line on a
board and sand it to test for even sanding.
Look for uniform removal of the line. If the
line is not removed uniformly, refer to the
adjustment section earlier in the instruction
manual.
DO NOT sand more than one board at a time.
Minor variations in thickness can cause one
board to be propelled by the rapidly spin-
ning sanding drum and ejected from the
machine. NEVER stand directly in front of
the outfeed area of the machine. Failure to
do so could result in severe personal injury.
NOTICE
We strongly recommend sending wide
stock through the sander two or three times
without adjusting the height. This is an
important method for preventing burning
your wood or ruining sandpaper.

Operation
G1066Z
Under most sanding conditions, a normal cut is
no more than 1⁄64". This depth can be achieved by
approximately ⁄4 turn of the handle. Excessively
heavy cuts can cause jamming, wood burning,
rapid paper wear, poor finish and belt slippage.
1
Your new Model G1066Z Drum Sander provides
a great amount of operator control during opera-
tion. To utilize this control, you should be familiar
with the variable speed and the load meter before
using the drum sander.
We recommend that wide stock be sent through
two to three times without adjusting the table
height—this is important for preventing burned
wood or ruined sandpaper. Also, turn the stock
180° to ensure an even cut. The following is the
correct start-up and operating procedure for this
model.
Variable Speed
The variable speed dial located on the control
panel allows you to increase the feed rate from 0-
20 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 stock.
1. Start the dust collector.
2. Place stock on the conveyor table and turn
the table handle to raise the conveyor table
until the stock barely touches the pressure
bar.
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.
3. Start the drum motor and the feed motor.
Pass the stock through the sander and slow-
ly raise the conveyor table while listening for
stock-to-drum contact. As soon as you hear
contact, stop raising the table and watch the
load meter (if it gets too high, immediately
lower the conveyor table). Retrieve your
workpiece by standing to the side of the
sander—NOT directly behind it.
Load Meter
The load meter located on the control panel dis-
plays the current amperage draw of the drum
motor. The needle rises when you increase the
load on the sanding drums and decreases when
you decrease the load. Use this meter to avoid
overloading your machine with too heavy of a cut.
NEVER exceed 25 amps—this is the maxi-
mum that your machine can safely handle!
4. Without moving the table, make multiple
passes and check your workpiece.
5. Check the sanded piece. Is the piece
smooth? Mark a squiggly pencil line on a
board and sand it to test for even sanding.
Look for uniform removal of the line. If the
line is not removed uniformly, refer to the
Adjustments section earlier in the instruction
manual.
Since various types of stock will react differently
with various loads, use trial-and-error to deter-
mine the best settings for your applications. As a
general rule, always start with a small load and
work your way up. We recommend that you do
not push your machine to its maximum load;
instead, make multiple passes or install a coars-
er grit paper.

Hook & Loop Sandpaper
Choosing Sandpaper
Although hook & loop sandpaper is convenient
and easy to install, care must be taken not to
overload it while sanding by taking excessively
heavy cuts.
There are many types of sanding belts to choose
from. We recommend Aluminum Oxide for gener-
al workshop environments. Below is a chart that
groups abrasives into different classes, and
shows which grits fall into each class.
Excessively heavy cuts will cause the underlying
hooks and loops to slightly depress and deform
under the sandpaper, resulting in small surface
grooves and ridges on all subsequently sanded
pieces. If this should happen, the only way to cor-
rect the situation is to unwrap and then re-wrap
the sandpaper around the drum to “reset” the
hooks and loops.
Grit
Type
60
Coarse
80-100
120-180
220
Medium
Fine
Simply stated: DO NOT take excessively heavy
cuts. If you need to remove material faster, switch
to a coarser grit of sandpaper.
Very Fine
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50.
The Model G1066/G1066Z/G1079 allows you to
place two different grit sandpapers on each
drum.The first drum should have a coarser grit
than the second. Usually this translates into com-
binations of successive group types. A common
selection for stock that is planed before being
sanded is a 100/150 grit combination.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types to
install on your sander.

SECTION 7: MAINTENANCE
Lubrication
Disconnect power to the
machine when perform-
ing any adjustments or
maintenance. Failure to
do this may result in seri-
ous personal injury.
Bearing blocks must be lubricated every 20 hours
of operation. Use a high-quality, lithium-based
grease. The grease fittings are located on the top
of each bearing block.
Other moving parts such as chains should be
lubricated periodically with a light machine oil.
Motor bearings need no lubrication.
General
Use only adequate lubrication. Too much lubri-
cant will attract dirt and sawdust and will clog the
chain mechanism.
Make a habit of inspecting your Model
G1066/G1066Z/G1079 each time you use it.
Check for the following conditions and repair or
replace when necessary.
•
•
•
•
•
Loose mounting bolts.
Worn switch.
Failure to routinely inspect your drum
sander for damage and wear could result in
unsatisfactory work results, premature com-
ponent or machinery failure, or operator
injury. We recommend you create a check-
list for routine inspection and maintenance.
Remember to always disconnect the drum
sander from its power source before
attempting to inspect, adjust, or repair this
machine!
Worn or damaged cords and plugs.
Damaged V-belt.
Any other condition that could hamper the
safe operation of this machine.
DO NOT attempt to investigate or adjust any
features of the machine while it is running.
Wait until the machine is turned off,
unplugged and all working parts have come
to a rest before you do anything!

Bearing Replacement
NOTICE
Make sure, when installing the new bearing,
that the lubrication groove in the bearing
will match the groove and grease fitting in
the housing once it is in place.
The tools necessary for this job are a large round
shaft screwdriver and a bench vise. Replace
bearing as follows:
1. Remove the roller housing from the drum
sander and clamp it tightly in a bench vise.
2. Insert the screwdriver into the center hole of
the bearing as shown in Figure 18. Lever the
bearing until it turns perpendicular to the
housing. Once the bearing is turned 90° from
the housing, it should slide free with little
effort. The housing is designed with notches
that allow the bearing to be inserted and
removed. It is important that you lever the
bearing so it turns in alignment to those
notches.
Figure 19. Matching bearing tab to notch.
Figure 18. Detaching bearing from housing.
3. Once the old bearing is removed, clean the
bearing housing. Insert the new bearing into
the notches in the housing as shown in
Figure 19. Twist the bearing clockwise 90°
after it reaches into the housing as far as it
will go as shown in Figure 20.
Figure 20. Inserting bearing into housing.
6. Re-attach the sanding head cover before
operating the sander.
4. Insert the screwdriver through the bearing,
as in step 2 and lever the bearing into its
proper position in the housing.
NOTICE
Lubricate the bearings sparingly after about
two months of sander operation. The bear-
ing requires very little grease, so avoid the
temptation to over-lubricate.
5. Press or tap the bearing and housing back
into place on the drum shaft. Re-adjust the
drum as necessary.

6. Board contains too much moisture
7. Sandpaper worn out
Sandpaper tearing
1. Drums not perpendicular to feed direction
2. Drums not parallel to conveyor table
3. Sandpaper edges overlapped
4. Tape is slipping
5. Too much material is removed at once

2. Uneven wear of sanding paper
Stock Slips on the Conveyor Belt
1. Too much material is removed at once
2. Too much dust on the conveyor belt surface
3. Worn conveyor belt
Shiny Spots on Sanded Surface
Marks on Sanded Surface
1. Sanding paper too old
2. Drums too high
