SAFETY GUIDELINES
SAFETY GUIDELINES:
WARNING!
Safety symbols in this Instruction Manual are used to flag possible dangers. The safety
symbols and their explanations require your full understanding. The safety warnings do
not, by themselves, eliminate any danger, nor are they substitutes for proper accident
prevention measures.
WARNING!
This Safety Alert Symbol indicates caution, warning, or danger. Failure to obey a safety
warning can result in serious injury to yourself or others. To reduce the risk of injury, fire,
or electric shock, always follow the safety precautions.
KNOW YOUR TOOL
To operate this tool, carefully read this Instruction Manual and all labels affixed to the sheet sander
before using. Keep this instruction manual available for future reference.
IMPORTANT
This tool should only be serviced by a qualified service technician. For more information, call the toll-
free helpline at 1-800-689-9928.
READ ALL INSTRUCTIONS THOROUGHLY.
SAVE THESE INSTRUCTIONS.
GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result in electric
shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or
fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.

SAFETY GUIDELINES
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
any adaptor plugs with earthed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, 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.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common 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 inattention while operating power tools may result in
serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment
such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate
conditions will reduce personal injuries.
• 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 energising power tools that have the
switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away
from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• 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.
• Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe injury
within a fraction of a second.

SAFETY GUIDELINES
POWER TOOL USE AND CARE
• 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.
• 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.
• Disconnect the plug from the power source and/or remove the battery pack,
if detachable, 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.
• 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 users.
• Maintain power tools and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
• Use the power tool, accessories, tool bits, etc., in accordance with these instructions,
taking into account the working conditions and the work to be performed. Use of the
power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
SERVICE
• 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 maintained.

OPERATING INSTRUCTIONS
WARNING!
• Always disconnect the sander from its power supply before attaching or removing sanding paper.
FPO
OPERATING INSTRUCTIONS
SANDING PAPER
This sander uses 1/4 sheet sanding paper, which can be cut from standard (228 x 280 mm) sanding
paper. For rough sanding, use coarse grit sanding paper. For smooth or final sanding, use fine grit
sanding paper.
ATTACH THE SANDING PAPER ( fig 1)
1. Unplug the sander.
2. Disengage the sanding-paper-clamp lever on one
side of the sanding pad by pushing the wire lever
towards the sander’s body.
3. Line up the edge of the sanding paper with the edge
of the sanding pad. Insert the sanding paper under
the clamp. Re-engage the sanding-paper-clamp
lever to lock the sanding paper in place.
4. Disengage the sanding-paper-clamp lever on the
other side of the sander. Stretch the sanding paper tightly over the foam pad and insert the outer edge of the
sanding paper under the clamp at the rear of the sander.
5. Line up the edge of the sanding paper with the edge of the sanding pad.
6. To lock the sanding paper in place, engage the sanding-paper-clamp lever.
USE THE PUNCH PLATE
After the sanding paper has been clamped to the sanding pad, use the punch plate to punch the dust-
collection holes.
1. Align the punch plate with the sanding pad and push down on the sander until the punch plate pierces the
sanding paper.
2. Remove the punch plate from the sanding pad.
NOTICE: In order for the dust-collection system to function properly, it is necessary that holes are punched in the sanding
paper such that the holes on the sanding paper align with the holes on the sanding pad.

OPERATING INSTRUCTIONS
INSTALL THE MICROFILTER DUST
CANISTER (fig 2)
Your sander is supplied with a dust canister to help
you keep the working area clean. The dust canister
is ideal for smaller jobs. For maximum efficiency, the
dust canister should be emptied frequently during
operation.
1. Disconnect the sander from the power source.
2. Align the slot on the dust canister with the rib on
the tool, and then push the dust canister onto the
tool until it locks into place.
REMOVE THE MICROFILTER DUST CANISTER (fig 2)
1. Disconnect the sander from the power source.
2. Simply pull the dust canister away from the tool.
ATTACH THE VACUUM HOSE (fig 3)
Directly attach the 1 1/4”(3.2 cm) vacuum hose to
the dust port, and then connect the opposite end of
the vacuum hose to a vacuum cleaner.
fig 3
WARNING!
• Collected sanding dust from sanding surface coatings (polyurethane, linseed oil, etc.) can self-ignite in dust
canister or elsewhere and cause fire. To reduce risk, empty dust canister frequently and strictly follow the
sander manual and coating manufacturer’s instructions.

OPERATING INSTRUCTIONS
CLEAN AND EMPTY THE DUST CANISTER
(fig 4 )
1. Remove the dust canister from the tool.
2. Hold the dust-canister body and remove the
microfilter by rotating it counter-clockwise.
3. Pour dust from the dust-canister body.
4. Knock excess dust out of the microfilter
or remove dust with a soft brush. You may
notice that all the dust may not come out of
the microfilter. This will not affect sanding
performance, but it will reduce dust collection
efficiency.
SELECT THE CORRECT SANDING PAPER
Available grades are: coarse, medium, and fine. Use
a coarse grit to sand down rough finishes, medium
grit to smooth the work, and fine grit to finish off.
It is best to make a trial run on a scrap piece of
material to determine the optimum grades of
sanding paper for a particular job.
TURN THE SANDER ON AND OFF (fig 5)
1. Connect the plug on the sander’s power cord to a
standard household outlet.
2. Start the sander by pushing the “on/off” switch
to the “I” position.
3. Turn the sander off by pushing the “on/off”
switch to the “O” position.
NOTICE:
• Do not switch from a coarse grit to a very fine grit in one step, because it may be difficult to remove the marks made by the
coarse grit. Use the coarsest grits for the roughing operation, and finish by using successively finer grits.
• The microfilter should not be rinsed with water.

SANDING TIPS
1. When starting and stopping sanding, contact the workpiece with the tool only after it has reached
full speed and remove it from the workpiece before turning off the switch. Operating in this manner will
prolong switch and motor life and will greatly increase the quality of your work.
2. Excessive pressure to the sander may result in an uneven sanding job and premature grit wear. Constant
and excessive pressure can cause overheating and possible damage to the motor, as well as premature
wear out of the pad.
a. Light pressure: recommended for fine work.
b. Moderate pressure: recommended for rough work.
c. Heavy pressure: does not allow the sanding paper to rotate properly.
3. If the surface is rough, start sanding with a coarse grit, then medium grit, and then finish with a fine or
extra-fine grit. This procedure will vary with different types of materials and work.
4. Continue to sand with each grit until the surface looks uniform.
5. To remove the greatest amount of stock, use a coarse grit and move the sander steadily over the entire
surface against the grain as well as with the grain. DO NOT REMAIN IN ONE SPOT TOO LONG. It may
remove too much material and uneven sanding will result.
6. Sanding with the grain of the wood gives the smoothest final finish.
