NOTICE
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.
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 eyeglasses 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.
-8-
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.
13. USE A GROUNDED EXTENSION CORD RATED FOR THE MACHINE AMPERAGE. Undersized cords overheat 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 conditions 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.
-9-
SAFETY
12. KEEP WORK AREA CLEAN AND WELL LIT. Clutter and dark shadows may cause accidents.
W1772/W1773 37" Drum Sander
Additional Safety for Drum Sanders
SAFETY
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 followed. 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 feeding 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 operations. 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.

ELECTRICAL
The machine must be properly set up before it is
safe to operate. DO NOT connect this machine to the
power source until instructed to do so in the "Power
Connection" portion of this manual.
The Model W1772 is wired for 220V single-phase operation.
Figure 2. Locking shutoff switch.
This machine must be hardwired to a locking shutoff
switch (Figure 2) by a qualified electrician. Since hardwiring involves a permanent installation with conduit
runs, this task can only be safely accomplished 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.
W1772 Electrical
Specifications
DO NOT work on your electrical system
if you are unsure about electrical
codes and wiring! Seek assistance from
a qualified electrician. Ignoring this
warning can cause electrocution, fire,
or machine damage.

W1773 220V/440V 3Phase Operation
The Model W1773 is prewired for 220V 3-phase operation,
but may be rewired for 440V 3-phase operation (see Page
13).
Figure 3. Locking shutoff switch.
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.
Phase Converter
Attempting to connect this machine to
the power source without a qualified
electrician greatly increases the risk
of electrocution, fire, or machine
damage.
The power from the manufactured power leg (wild wire)
of a phase converter fluctuates, which may damage electrical 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.

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.
•
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.
The Model W1772/W1773
is an extremely heavy
machine. Serious personal injury may occur if
safe moving methods are
not followed. To be safe,
you will need assistance
and power equipment
when moving the shipping crate and removing
the machine from the
crate.
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, adjusting or operating equipment.

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 hardware is not included.
Figure 14. Lifting the sander.
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.
NOTICE
Anchor studs are stronger and more permanent alternatives 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.
Lag Screw and Anchor

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.

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, 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.
We recommend using a dust collection system that produces 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.

SET UP
To connect the dust ports to a dust collector, do these
steps:
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
lift off the face plate.

OPERATIONS
General
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 sanding conditions, the depth should not exceed 1/64" (approx.
3
/4 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.
OPERATIONS
2.
Start the conveyor and sanding drums and feed the
workpiece into the sander. SLOWLY raise the conveyor 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.
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.
NOTICE
Adjusting the variable speed when the
conveyor motor is OFF can damage the
V-belt and the adjusting mechanism.
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) counterclockwise to increase the feed speed, or clockwise
to decrease the feed speed.
Figure 25. Variable speed knob.
-24-
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 sanding 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 energize, and capacitor or motor damage will occur.
Amp load is directly affected by many factors such as
feed rate, depth of cut, wood type, sandpaper grit, and
workpiece width.

2.
Start the dust collector, the drum motor, and the
feed motor.
3.
Feed the workpiece through the sander while standing to the side and monitor the amp meter; if it
approaches the maximum amp load, lower the conveyor table.
4.
Run wide stock through two or three times without 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.

Close all covers and panels before
starting the drum sander. Failure to
do so could result in severe personal
injury.
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

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 prevent 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
/16" to prevent damage to the workpiece and the
drum sander.
OPERATIONS
1
•
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 sanding 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 sanding 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 scratches for the finish passes.

W1772/W1773 37" Drum Sander
Choosing Sandpaper
There are many types of sanding belts to choose from.
We recommend Aluminum Oxide for general workshop
environments. To the side is a chart that groups abrasives
into different classes, and shows which grits fall into each
class.
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.
The Model W1772/W1773 allows you to place a different grit sandpaper on each drum. The front drum should
have a coarser grit than the rear. Usually this translates
into combinations of successive group types. A common
selection for stock that is planed before being sanded is a
100/150 grit combination.

Regular periodic maintenance on your Model W1772/
W1773 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.
Worn switch.
Worn or damaged cords and plugs.
Worn or damaged sandpaper.
Damaged V-belts.
Any other condition that could hamper the safe
operation of this machine.
OFF
MAKE SURE that your machine is
unplugged during all maintenance
procedures! If this warning is ignored,
serious personal injury may occur.
Cleaning
Cleaning the Model W1772/W1773 is relatively easy. From
time to time, vacuum wood dust off of the internal components, especially the motor.
Grease
Fitting
Lubrication
MAINTENANCE
Moving parts, such as chains, should be lubricated periodically 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.
Figure 32. Location to lubricate pillow
bearing.
Gearbox: Change the oil in the gearbox every 500 hours
with new 80-90W automotive grade gear oil.

Table Lift Screws: Should be cleaned with mineral spirits
and painted with lithium grease every six months. Then,
move the table up or down to spread the grease thoroughly over the threads. Do not overlubricate.
Worm Gear: Paint a light coat of lithium grease on the
worm gear threads (Figure 36) once a year.
Failure to routinely inspect your drum sander for
damage and wear could result in unsatisfactory work
results, premature component or machinery failure,
or operator injury. We recommend you create a
checklist 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!

Gauge Blocks
The gauge blocks described here will be required to complete 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.
MAKE SURE that your machine is
unplugged during all service procedures!
If this warning is ignored, serious
personal injury may occur.
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 opposite side to square up the two edges of the 2x4, as
shown in Figure 38.
3.
Figure 37. Edge jointing on a jointer.
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.
Note: Save one of the 6" pieces for making a small
gauge block in Drum Adjustments on Page 38.

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 inspected and re-tensioned if necessary.
OFF
Proper tension is important for optimum power transmission. 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.
Figure 39. Checking V-belt tension with a
straightedge and a ruler.
To adjust V-belt tension, do these steps:
1.
DISCONNECT POWER TO THE SANDER!
2.
Remove the table height handwheel and open the
pulley cover.
3.
Using a 19mm wrench, turn the motor mount nuts in
the direction shown in Figure 40 to loosen or tighten
the V-belts.

Removal/Replacement
Replace the V-belt if you notice fraying, cracking, glazing, 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 pulleys, replacing them with a MATCHED set, then re-tensioning them.
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 optimum performance.
-33-
SERVICE
Note: A matched set means both the V-belts are the same
size and also have the same serial number.
W1772/W1773 37" Drum Sander
Each pulley can be adjusted by loosening the set screw
that secures the pulley to the shaft, sliding the pulley in/
out, and retightening the set screw to lock the pulley in
place.
OFF
To align the pulleys, do these steps:
1.
DISCONNECT POWER TO THE SANDER!
2.
Remove the table height handwheel, open the pulley
cover, and remove the V-belts.
3.
Place a straightedge across the face of the motor pulley and the front drum pulley to check the alignment.
The straightedge should sit evenly on the top and bottom part of both pulleys, as shown in Figure 41.
4.
Repeat Step 3 with the straightedge placed against
the motor pulley and rear drum pulley.
5.
Loosen the pulleys and adjust them as necessary until
they are all coplanar with each other.

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.
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 conveyor 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.
This step will aid you in keeping track of the rotations
as you turn the bolts, so the bolts remain as even as
possible.

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 tighten 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 correct.

W1772/W1773 37" Drum Sander
Drum Adjustments
There are three adjustments for the sanding drums: 1) the
drums must be perpendicular to the feed direction (parallel 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 approximately 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 perpendicular 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.

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 parallel to the machine frame).

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 adjustment. 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 sanding 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:
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 conveyor table and position them under the drums, as
shown in Figure 55.
4.
Raise the table up until the gauge blocks are approximately 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".

Note: The 0.017"–0.025" setting is a recommended
range and includes the 0.010" setting on the rear
drum and the additional 0.007" to 0.015" height from
Step 12 (See Figure 58). Some trial-and-error may
be needed to find the optimal setting based upon the

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 adjustable 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 reducing 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 happens, 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.
SERVICE
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.

Scale Pointer Calibration
For the scale pointer to be accurate, it must be calibrated.
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.
2.
Sand a workpiece with the drum sander and measure
the thickness of the sanded workpiece.
Figure 61. Scale pointer screw.
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:
1.
DISCONNECT POWER TO THE SANDER!
2.
Remove the handwheel and open the pulley cover.
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.

Table Lift Scews
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.
-43-
SERVICE
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.
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.
SERVICE
To adjust the table lift screws, do these steps:
Figure 63. Marking sprocket tooth and
chain.
1.
DISCONNECT POWER TO THE SANDER!
2.
Open the side cover.
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.
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 setting.
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 conveyor within 0.002" side-to-side.
