GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Power tools create sparks which may ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
2. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.
CALIFORNIA PROPOSITION 65 WARNING
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities may contain
chemicals, including lead, known to the State of Califor-
nia to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies depending on
how often you do this type of work. To reduce your ex-
posure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

2.3A 18 gauge 16 gauge 16 gauge 14 gauge
3. Check with a licensed electrician or service personnel if you do not completely under-
stand the grounding instructions or whether the tool is properly grounded.
4. Use only three-wire extension cords that have three-pronged plugs and outlets that
accept the tool’s plug. Repair or replace a damaged or worn cord immediately.
CAUTION! In all cases, make certain the outlet in question is properly grounded. If you
are not sure, have a licensed electrician check the outlet.
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding provides the path of least resistance for an electric current
and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding
conductor and 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.
1. Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a licensed electri-
cian.
2. Improper connection of the equipment grounding conductor can result in electric shock. The conductor with the
green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of
the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a live terminal.
1. Examine extension cord before use. 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.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A 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.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
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 ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.

UPPER GUARD
Install the upper guard (Fig. 8 - 2) onto the belt sanding arm
using the upper guard locking knob (Fig. 8 - 3) to secure it
in place.
BELT TRACKING
Belt tracking means adjusting the belt to ride in the center
of the rollers so that it runs true (does not wander left or
right during operation). The sander is equipped with a belt
tracking adjustment knob (Fig. 8 - 1).
To adjust the belt tracking:
1. Remove the upper guard locking knob (Fig. 8 - 3) and the
upper guard (Fig. 8 - 2).
2. While holding the side cover in place, remove the three
screws and washers holding the cover in place (Fig. 8 - 5.
Fig. 9 - 1 & 2). Remove the side cover.
3. Rotate the sanding disc with your hand. This causes the
belt to slowly rotate. Watch to see if it starts to move left or
right (toward or away from the body of the sander). If the
belt wanders from the belt rollers, use the belt tracking ad-
justment knob (Fig. 8 - 1) to adjust the angle of the rollers.
Keep rotating the disc with one hand while turning the belt
tracking knob until the belt rides in the center of the rollers.
3. Re-install the side cover, upper guard, and upper guard
locking knob. Connect the cord to the power source. Turn
the sander ON and then quickly OFF to verify that the belt is
riding true in the center of the rollers. If it does not, repeat
the above steps to adjust the belt tracking.
SQUARING THE TABLE
The best results are obtained when the tables are square
(exactly 90°) with the belt and the disc sanding surfaces.
1. Make sure the switch is in the OFF position and the cord
is disconnected from the power source.
2. Loosen the locking knobs for the disc table or the locking
lever for the belt table. Place a square (not included) on the

BELT SANDER PLATEN
The platen (p. 13, Fig. 8 - 4) is the steel support plate that
is positioned behind the sanding belt and underneath the
sanding belt table. It rises from the body of the sander to
a point several inches above the belt table’s surface. The
platen provides the necessary support to the workpiece
during sanding operations. It should be adjusted so that it
is almost touching the back of the sanding belt.
To adjust the platen:
1. Make sure the switch is in the OFF position and the cord
is disconnected from the power source.
2. You will need to remove the locking lever and belt table
to access the hex screws that hold the platen in place.
3. Loosen the two hex screws (Fig. 10) that secure the
platen to the sander’s frame. Adjust the platen so that it is
almost touching the back of the belt. Re-tighten both hex
screws.
TESTING THE MACHINE
Once you have properly assembled the machine, perform a test run to see that everything powers up and runs cor-
rectly.
All of the tools for assembly and adjustments should be removed and cleared away before turning on the machine.
During the test run, make sure the ON/OFF switch along with all safety features are working properly before apply-
ing a load.
After connecting the machine to the correct power source, stand to the side of the machine and power it on. During
the test run, take note of any unusual noises, vibrations or rattling. If any of these occur, turn off the machine and
unplug it from the power source immediately. Check all the parts you have assembled and try to find the problem.

ON/OFF SWITCH
1. To start the sander, push the switch to the ON position.
2. To stop the sander, push switch to the OFF position.
SURFACE SANDING ON THE BELT
Hold the workpiece firmly with both hands. Keep fingers away from sanding belt. Keep the workpiece flat against the
belt table and move it slowly across the sanding belt. Apply enough pressure to remove material; excessive pressure
will reduce sanding efficiency.
END SANDING AND OUTSIDE CURVE SANDING ON THE DISC
Use for sanding the ends of small and narrow workpieces and outside curved edges. Always work on the left side of
the disc (downward rotation side), holding the workpiece firmly with light pressure against the sanding disc.
The disc sander rotates counterclockwise, downward toward the table on the left side of the disc and upward from
the table on the right side of the disc. Always use the left side of the disc; using the right side of the disc could cause
the workpiece to fly up or kickback and could result in injury.
MITER GAUGE - DISC SANDER
A miter gauge is supplied with your sander, and can be used on the disc table. The miter gauge head can be set
anywhere up to 45° (right or left) by loosening the locking knob, setting the miter gauge head to the desired angle,
and retightening the locking knob.
Use of the miter gauge is recommended for sanding small end surfaces on the sanding disc.
NOTE: Always move the workpiece across the sanding disc from the center of the disc to the left side, and be sure
to hold the workpiece down tightly onto the table surface.
OPERATION
WARNING! Use extra caution when sanding very thin pieces, and apply only enough pressure to allow the
sanding belt to remove the material.
WARNING! To avoid personal injury and/or damage to the workpiece, become familiar with the rotation of
the belt and disc sanding surfaces.

16

SANDING BELT REPLACEMENT
1. Make sure the switch is in the OFF position and the cord is
disconnected from the power source.
2. Remove the upper guard locking knob (Fig. 11 - 3) and the
upper guard (Fig. 11 - 2).
3. While holding the side cover in place, remove the three
screws and washers holding the cover in place (p. 13, Fig.
8 - 5. Fig. 9 - 1 & 2). Remove the side cover.
4. Push the shaft guard (Fig. 11 - 1) forward towards the
work table. (This will shift the middle roller forwards and
create slack in the belt.) While pushing the shaft guard for-
wards, slide the belt off of the rollers with your other hand.
5. Place a new belt on the rollers. Check that the arrow on
the back of the new belt is pointed in the direction of travel.
7. Adjust tracking (instructions on p. 13) accordingly and
reinstall the side cover, upper guard, and upper guard lock-
ing knob.

2. Remove the sanding disc table by removing the two locking knobs on either side of the sanding disc. Remove the
disc dust port by removing the three screws and washers. See figures on p. 12.
3. Remove the used sanding disc. A WEN Heat Gun (Model Number 2020 or HG1022) can help to soften up the
adhesive to make for an easier, cleaner removal. Wipe the sanding disc plate clean.
4. Peel the backing from the new sanding disc, align the disc with the plate and press the sanding disc firmly on to
the plate.
5. Reinstall the disc dust port, work table, and locking knobs.
