GENERAL SAFETY RULES
Safety is a combination of common sense, staying alert and knowing how your item works. SAVE THESE
SAFETY INSTRUCTIONS.
WARNING: To avoid mistakes and serious injury, do not plug in your tool until the following
steps have been read and understood.
1. READ and become familiar with this entire instruction manual. LEARN the tool’s applications, limitations,
and possible hazards.
2. AVOID DANGEROUS CONDITIONS. Do not use power tools in wet or damp areas or expose them to
rain. Keep work areas well lit.
3. DO NOT use power tools in the presence of flammable liquids or gases.
4. ALWAYS keep your work area clean, uncluttered, and well lit. DO NOT work on floor surfaces that are
slippery with sawdust or wax.
5. KEEP BYSTANDERS AT A SAFE DISTANCE from the work area, especially when the tool is operating.
NEVER allow children or pets near the tool.
6. DO NOT FORCE THE TOOL to do a job for which it was not designed.
7. DRESS FOR SAFETY. Do not wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) when
operating the tool. Inappropriate clothing and items can get caught in moving parts and draw you in. ALWAYS
wear non-slip footwear and tie back long hair.
8. WEAR A FACE MASK OR DUST MASK to fight the dust produced by sawing operations.
WARNING: Dust generated from certain materials can be hazardous to your health. Always
operate the tool in a well-ventilated area and provide for proper dust removal. Use dust collection
systems whenever possible.
9. ALWAYS remove the power cord plug from the electrical outlet when making adjustments, changing parts,
cleaning, or working on the tool.
10. KEEP GUARDS IN PLACE AND IN WORKING ORDER.
11. AVOID ACCIDENTAL START-UPS. Make sure the power switch is in the OFF position before plugging
in the power cord.
12. REMOVE ADJUSTMENT TOOLS. Always make sure all adjustment tools are removed from the saw
before turning it on.
13. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to OFF. Do not leave
the tool until it has come to a complete stop.

4
14. NEVER STAND ON A TOOL. Serious injury could result if the tool tips or is accidentally hit. DO NOT store
anything above or near the tool.
15. DO NOT OVERREACH. Keep proper footing and balance at all times. Wear oil-resistant rubber-soled foot-
wear. Keep the floor clear of oil, scrap, and other debris.
16. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow instruc-
tions for lubricating and changing accessories.
17. CHECK FOR DAMAGED PARTS. Check for alignment of moving parts, jamming, breakage, improper
mounting, or any other conditions that may affect the tool’s operation. Any part that is damaged should be properly
repaired or replaced before use.
18. MAKE THE WORKSHOP CHILDPROOF. Use padlocks and master switches and ALWAYS remove start-
er keys.
19. DO NOT operate the tool if you are under the influence of drugs, alcohol, or medication that may affect your
ability to properly use the tool.
20. USE SAFETY GOGGLES AT ALL TIMES that comply with ANSI Z87.1. Normal safety glasses only have
impact resistant lenses and are not designed for safety. Wear a face or dust mask when working in a dusty environ-
ment. Use ear protection such as plugs or muffs during extended periods of operation.
GENERAL SAFETY RULES
WARNING: Do not operate the spindle sander until it is completely assembled and installed according
to the instructions.
1. Know your spindle sander; if any part is missing, bent, broken, or otherwise does not function properly, replace
it before using the spindle sander.
2. Be familiar with the type of work to be performed when operating any power tool, including the spindle sander.
3. Hold the workpiece securely to the sander table with both hands to protect yourself and your project.
4. Be aware of the direction of the spindle’s rotation. Be certain to feed the workpiece against the rotation of the
spindle.
5. Always keep your hands out of the path of the sander and away from the sanding sleeves. Avoid hand positions
where a sudden slip could cause your hand to move into the spindle. Do not reach underneath the workpiece or
around the sanding sleeve while the spindle is rotating.
6. Disconnect the sander after turning off the power switch. Wait for the spindle to stop rotating before performing
maintenance. The sander must be disconnected when not in use or when changing parts and accessories.
7. Make sure there are no nails or other foreign objects present in the area of the workpiece to be sanded.
SPECIFIC RULES FOR THE SPINDLE SANDER

5
SPECIFIC RULES FOR THE SPINDLE SANDER
8. Do not use the spindle sander for wet sanding. Failure to comply may cause electric shock leading to injury or
death.
9. Use only identical replacement parts when servicing the sander.
10. Wait until the spindle comes to a complete stop before touching the workpiece.
11. Take precautions when sanding painted surfaces. Sanding lead-based paint is NOT RECOMMENDED. The
contaminated dust is too difficult to control, and could cause lead poisoning. When sanding paint:
• Protect your lungs. Wear a dust mask or respirator.
• Do not allow children or pregnant women in the work area until the paint sanding job is finished
and the clean-up is completed.
• Do not eat, drink, or smoke in an area where painted surfaces are being sanded.
• Use a dust collection system when possible. Seal the work area with plastic. Do not track paint dust
outside of the work area.
• Thoroughly clean the area when the paint sanding project is completed.
ELECTRICAL INFORMATION
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.
GUIDELINES FOR USING EXTENSION CORDS
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting
in loss of power and overheating. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected
with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF
position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a
lower voltage will damage the motor.
WARNING: Although this tool is double-insulated, it must still be grounded while in use to protect the
operator from electric shock.

UNPACKING
Carefully unpack the spindle sander and all its parts, and compare
against the list below (Fig. 1). Do not discard the carton or any packag-
ing until the spindle sander is completely assembled. If any parts are
missing or damaged, contact the WEN customer support line.
This spindle sander requires some assembly. For your safety, completely
assemble the oscillating spindle sander before connecting it to the power
or switching it on.
DUST COLLECTION
A 1-1/2” dust port is located at the rear of the machine as seen on page
6 (Item H) or in Fig. 2 to the right. This can be connected to a dust-
collection system (not included).

ASSEMBLY AND ADJUSTMENTS
SELECTING A SANDING SLEEVE
Select a sleeve that is an appropriate size for sanding your workpiece, and install the corresponding throat plate.
THROAT PLATE SELECTION (Fig. 5)
WARNING: Failure to install the correct throat plate for the sleeve size being used can lead to both
personal injury and damage to the spindle sander.
Use the throat plate with the smallest amount of clearance between the plate and the spindle sleeve (Fig. 5). Use
the chart below to help you determine which throat plate and upper spindle washer to use with each spindle sleeve.
Sanding Throat plate Upper spindle
sleeve diameter size washer size
1/2" .5" small
3/4" .75" medium
1" 1" medium
1 1/2" 1.5" large
2" 2" large
3" 3" large
SPINDLE SANDER MOUNTING (Figs. 3 and 4)
To mount the spindle sander permanently, choose a solid benchtop. If the sander is to be used portably, mount
the sander to a mobile mounting board and use clamps to secure it to a solid surface (Fig. 4). When mounting the
sander on either a board or a benchtop, use the corner holes as guides (Fig. 3) and secure the sander using bolts (not
included). Lag bolts should go far enough into the bench in order to secure the sander, while machine bolts must
pass through the benchtop completely.

ASSEMBLY AND ADJUSTMENTS
INSTALLING A SANDING SLEEVE (Fig. 6)
All sleeves with the exception of the 1/2” sleeve fit over a rubber sanding drum. To install a sleeve:
1. Place the lower spindle washer (2) over the spindle (1) with the fin side facing down.
2. Select a sanding sleeve (5) for the job that you are planning. Select the corresponding rubber sanding drum (4).
Note: Do not use a sanding drum with the 1/2” sanding sleeve.
3. Select the throat plate (3) that provides the smallest clearance between the sanding sleeve (5) and the opening in
the throat plate.
4. Place the throat plate (3) over the spindle (1), and fit it into the opening in the table.
5. Place the sanding drum (4) over the spindle.
6. Slide the sanding sleeve (5) over the sanding drum (4).
7. Place the appropriate upper spindle washer (6) over the spindle (1).

against the sanding sleeve (5). Do not overtighten (Fig. 7).
Fig. 6
Fig. 7

ON/OFF SWITCH (Fig. 8)
The keyed switch is intended to prevent unauthorized use of the sander.
WARNING: Remove the safety key whenever the sander is not in use. Place the key in a safe place
and out of the reach of children.
1. To turn sander ON, insert the safety key (1) into the key slot (2) in the center of the switch.
2. Push key firmly into the slot, then push switch to the ON position to start the sander.
3. To turn the sander OFF push switch to the OFF position.
4. Remove the safety key when the sander has come to a complete stop by gently pulling it forward and out.
Note: If the safety key is removed while the sander is running, the sander can be turned OFF, but it cannot be
restarted without inserting the safety key.
OPERATING THE SANDER (Fig. 9)
WARNING: Do not sand metal with the spindle sander. Sanding metal will create sparks that present
a serious fire hazard.
The spindle rotates in a counterclockwise (1) direction.
1. Make sure the hex nut (2) on top of the spindle is fastened securely.
2. Turn the sander ON, and let the motor reach full speed.
3. Feed the workpiece gradually against the sanding sleeve.
• Do not force the workpiece.
• Guide the workpiece from the right to left (3). If you guide the workpiece in the opposite direction, the
rotation forces of the spinning sanding sleeve will tend to throw or bounce the workpiece away from the
sanding sleeve.

MAINTENANCE
WARNING: For your own safety, turn the switch OFF and remove the plug from the electrical out-
let before adjusting or performing maintenance or lubrication work on the belt/disc sander.
Before using, check to make sure parts are not damaged, missing, or worn. Check for alignment of
moving parts, binding of moving parts, improper mounting, or any other conditions that may affect the sander
operation. If any of these conditions exist, do not use the sander until parts are replaced or the sander is properly
repaired. Frequently blow or vacuum dust from all sanding parts and motor housing.
WARNING: Any attempt to repair or replace electrical parts on this tool may be hazardous. Repairs
should be done by a qualified service technician.
LUBRICATION
Ball bearings are grease packed at the factory and require no further lubrication. Use a spray lubricant on all mov-
ing table parts to ensure smooth operation.
CLEANING
Frequently blow away or vaccuum all sander parts and the motor housing. Periodically, remove the throat plate
and lower spindle washer and remove any dust accumulation in the throat plate area.
WARNING: Never use flammable or combustible solvents around power tools. When servicing,
use only identical WEN replacement parts. Use of other parts may be hazardous or induce product
failure.
TROUBLESHOOTING
1. Over time, if the performance of the tool diminishes, or it stops working completely, it may be necessary to re-
place the Carbon Brushes by removing the Brush Holder. This procedure should only be completed by a qualified
technician. If the Carbon Brushes are not worn down, try cleaning the Carbon Brush tips with an ink eraser.
2. If the Sanding sleeve stops rotating when you touch it or press the stock material against it, turn off the machine
at once. Unplug the machine and check to make sure that the Hex Nut is threaded on tight to the Spindle.
