GENERAL SAFETY RULES  
Avoid accidental starting. Be sure switch is off be-  
fore plugging in. Carrying tools with your finger on the  
switch or plugging in tools that have the switch on invites  
accidents.  
WARNING:  
Read and understand all instructions. Failure to fol-  
low all instructions listed below, may result in electric  
shock, fire and/or serious personal injury.  
Remove adjusting keys or wrenches before turning  
the tool on. A wrench or a key that is left attached to a  
rotating part of the tool may result in personal injury.  
SAVE THESE INSTRUCTIONS  
WORK AREA  
Do not overreach. Keep proper footing and balance  
at all times. Proper footing and balance enables better  
control of the tool in unexpected situations.  
Keep your work area clean and well lit. Cluttered  
Use safety equipment. Always wear eye protection.  
Dust mask, nonskid safety shoes, hard hat, or hearing  
protection must be used for appropriate conditions.  
benches and 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.  
Do not wear loose clothing or jewelry. Contain long  
hair. Loose clothes, jewelry, or long hair can be drawn  
into air vents.  
Keep bystanders, children, and visitors away while  
operating a power tool. Distractions can cause you to  
lose control.  
Do not use on a ladder or unstable support. Stable  
footing on a solid surface enables better control of the  
tool in unexpected situations.  
ELECTRICAL SAFETY  
TOOL USE AND CARE  
Double insulated tools are equipped with a polarized  
plug (one blade is wider than the other). This plug  
will fit in a polarized outlet only one way. If the plug  
does not fit fully in the outlet, reverse the plug. If it  
still does not fit, contact a qualified electrician to in-  
stall a polarized outlet. Do not change the plug in any  
Use clamps or other practical way to secure and sup-  
port the workpiece to a stable platform. Holding the  
work by hand or against your body is unstable and may  
lead to loss of control.  
Do not force tool. Use the correct tool for your appli-  
cation. The correct tool will do the job better and safer at  
the rate for which it is designed.  
way. Double insulation  
eliminates the need for the  
three-wire grounded power cord and grounded power  
supply system.  
Do not use tool if switch does not turn it on or off.  
Any tool that cannot be controlled with the switch is dan-  
gerous and must be repaired.  
Avoid body contact with grounded surfaces such as  
pipes, radiators, ranges, and refrigerators. There is  
an increased risk of electric shock if your body is grounded.  
Disconnect the plug from power source before mak-  
ing any adjustments, changing accessories, or stor-  
ing the tool. Such preventive safety measures reduce  
the risk of starting the tool accidentally.  
Don’t expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of elec-  
tric shock.  
Do not abuse the cord. Never use the cord to carry  
the tools or pull the plug from an outlet. Keep cord  
away from heat, oil, sharp edges, or moving parts.  
Replace damaged cords immediately. Damaged cords  
increase the risk of electric shock.  
Store idle tools out of the reach of children and other  
untrained persons. Tools are dangerous in the hands of  
untrained users.  
Maintain tools with care. Keep cutting tools sharp and  
clean. Properly maintained tools with sharp cutting edges  
are less likely to bind and are easier to control.  
When operating a power tool outside, use an outdoor  
extension cord marked “W-A” or “W”. These cords are  
rated for outdoor use and reduce the risk of electric shock.  
Check for misalignment or binding of moving parts,  
breakage of parts, and any other condition that may  
affect the tool’s operation. If damaged, have the tool  
serviced before using. Many accidents are caused by  
poorly maintained tools.  
PERSONAL SAFETY  
Stay alert, watch what you are doing and use com-  
mon sense when operating a power tool. Do not use  
tool while tired or under the influence of drugs, alco-  
hol, or medication. A moment of inattention while oper-  
ating power tools may result in serious personal injury.  
Use only accessories that are recommended by the  
manufacturer for your model. Accessories that may be  
suitable for one tool, may become hazardous when used  
on another tool.  
Dress properly. Do not wear loose clothing or jew-  
elry. Contain long hair. Keep your hair, clothing, and  
gloves away from moving parts. Loose clothes, jew-  
elry, or long hair can be caught in moving parts.  
Keep the tool and its handle dry, clean and free from  
oil and grease. Always use a clean cloth when cleaning.  
Never use brake fluids, gasoline, petroleum-based prod-  
ucts, or any strong solvents to clean your tool. Following  
this rule will reduce the risk of loss of control and deterio-  
ration of the enclosure plastic.

EXTENSION CORDS  
DOUBLE INSULATION  
When using a power tool at a considerable distance from a  
power source, be sure to use an extension cord that has the  
capacitytohandlethecurrentthetoolwilldraw.Anundersized  
cord will cause a drop in line voltage, resulting in overheating  
and loss of power. Use the chart to determine the minimum  
wire size required in an extension cord. Only round jacketed  
cords listed by Underwriter’s Laboratories (UL) should be  
used.  
Double insulation is a concept in safety in electric power  
tools, which eliminates the need for the usual three-wire  
grounded power cord. All exposed metal parts are isolated  
from the internal metal motor components with protecting  
insulation.Doubleinsulatedtoolsdonotneedtobegrounded.  
WARNING:  
The double insulated system is intended to protect the  
user from shock resulting from a break in the tool's  
internal insulation. Observe all normal safety precau-  
tions to avoid electrical shock.  
When working outdoors with a tool, use an extension cord  
thatisdesignedforoutsideuse.Thistypeofcordisdesignated  
with "WA" on the cord's jacket.  
Before using any extension cord, inspect it for loose or  
exposed wires and cut or worn insulation.

SANDING DISC SELECTION  
BACKING  
PAD  
Selecting the correct size grit and type sanding disc is an  
extremely important step in achieving a high quality sanded  
finish. Aluminum oxide, silicon carbide, and other synthetic  
abrasives are best for power sanding. Natural abrasives,  
such as flint and garnet are too soft for economical use in  
power sanding.  
In general, coarse grit will remove the most material and

grit and finer grit used for finishing of the surface. Always  
continue sanding with each grit until surface is uniform.

REMOVING SANDINGDISCBEFORESTORAGE  
Do not store your sander with the sanding disc installed.  
Heat generated from sanding causes the pressure sensitive  
adhesive to flow and form a tight bond between the backing  
pad and sanding disc.  
WARNING:  
The tool should never be connected to power supply  
when you are assembling parts, making adjustments,  
assembling or replacing sanding disc, cleaning, or when  
notinuse.Disconnectingyoursandercanpreventaccidental  
Removing the sanding disc soon after you have finished a  
sanding operation avoids letting the adhesive set up. If the  
sanding disc is left on the backing pad for an extended period  
of time after use, the adhesive will set up and cause the  
sanding disc to become difficult to remove.  
starting that could cause serious personal injury.  
It may also tear when removing. When this situation occurs,  
it becomes difficult to clean the backing pad for the next  
sanding disc.  
TO ATTACH PRESSURE SENSITIVE  
ADHESIVE SANDING DISC  
See Figure 2.  
NOTE: If you forget to remove the sanding disc after a  
sanding operation, sand for a few minutes to soften the  
adhesive backing before attempting to remove sanding disc.  
Unplug your sander.  
Carefully peel paper backing from the pressure sensitive  
adhesive type sanding disc.  
Align holes in sanding disc with holes in backing pad,  
then carefully press sticky side of disc against pad as  
tight as possible.  
NOTE: Holes in sanding disc must line up with holes in  
the backing pad in order for the dustless feature of your  
sander to function properly.  
NOTE: It is recommended that you clean backing pad  
occasionally by brushing lightly with a small brush. Dust  
buildup on backing pad could cause sanding disc not to  
stick properly.

DO NOT FORCE. The weight of the unit supplies adequate  
pressure, so let the sanding disc and sander do the work.  
Applying additional pressure only slows the motor, rapidly  
wears sanding disc and greatly reduces sander speed.  
Excessive pressure will overload the motor causing possible  
damage from motor overheating and can result in inferior  
work. Any finish or resin on wood may soften from the  
frictional heat. Do not allow sanding on one spot too long  
as the sander's rapid action may remove too much material,  
making the surface uneven.

Extended periods of sanding may tend to overheat the  
motor. If this occurs, turn sander off and wait until sanding  
disc comes to a complete stop, then remove it from  
workpiece. Remove your hand from vent area, remove  
sanding disc, then with your hand removed from vent area,  
turn sander on and run it free without a load to cool motor.  
Flush sanding can be performed with your sander. As  
shown in Figure 7, the front edge of your sander allows  
flush sanding. Upon completion of sanding operation, turn  
sander off and wait until sanding disc comes to a complete  
stop before removing from workpiece.
