GENERAL SAFETy RULES  
with your finger on the switch or plugging in power tools  
that have the switch on invites accidents.  
WARNING!  
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.  
Read all instructions. Failure to follow all instructions  
listed below may result in electric shock, fire and/or  
serious injury. The term “power tool” in all of the warn-  
ings listed below refers to your mains-operated (corded)  
power tool or battery-operated (cordless) power tool.  
Dress properly. Do not wear loose clothing or jewelry.  
keep your hair, clothing and gloves away from moving  
parts. Loose clothes, jewelry 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 these devices can  
reduce dust-related hazards.  
SAVE THESE INSTRUCTIONS  
WORk AREA SAFETy  
keep work area clean and well lit. Cluttered or dark  
areas invite accidents.  
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 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 children and bystanders 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  
power tool in unexpected situations.  
ELECTRICAL SAFETy  
Power tool plugs must match the outlet. Never modify  
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.  
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.  
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 elec-  
tric shock.  
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  
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.  
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. Check for misalignment or bind-  
ing 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.  
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 exten-  
sion cord suitable for outdoor use. Use of a cord suit-  
able for outdoor use 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.  
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.  
Use safety equipment. Always wear eye protection.  
Safety equipment such as dust mask, non-skid safety  
shoes, hard hat, or hearing protection used for appropri-  
ate conditions will reduce personal injuries.  
Use the power tool, accessories and tool bits etc., in  
accordance with these instructions and in the manner  
intended for the particular type of power tool, taking  
into account the working conditions and the work to  
be performed. Use of the power tool for operations dif-  
ferent from those intended could result in a hazardous  
situation.  
Avoid accidental starting. Ensure the switch is in the  
off-position before plugging in. Carrying power tools

fully. Learn its applications and limitations, as well as  
the specific potential hazards related to this power  
tool. Following this rule will reduce the risk of electric  
shock, fire, or serious injury.  
Make sure your extension cord is in good condi-  
tion. When using an extension cord, be sure to use  
one heavy enough to carry the current your product  
will draw. A wire gauge size (A.W.G.) of at least 16 is  
recommended for an extension cord 50 feet or less  
in length. A cord exceeding 100 feet is not recom-  
mended. If in doubt, use the next heavier gauge. The  
smaller the gauge number, the heavier the cord. An  
undersized cord will cause a drop in line voltage resulting  
in loss of power and overheating.

ELECTRICAL  
DOUbLE INSULATION  
EXTENSION CORDS  
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. Double insulated tools do not need  
to be grounded.  
When using a power tool at a considerable distance from  
a power source, be sure to use an extension cord that has  
the capacity to handle the current the product will draw. An  
undersized 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.  
WARNING:  
When working outdoors with a product , use an extension  
cord that is designed for outside use. This type of cord is  
designated with “WA” on the cord’s jacket.  
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 precautions  
to avoid electrical shock.  
Before using any extension cord, inspect it for loose or  
exposed wires and cut or worn insulation.  
NOTE:Servicingofaproductwithdoubleinsulationrequires  
extreme care and knowledge of the system and should  
be performed only by a qualified service technician. For  
service, we suggest you return the product to your near-  
est authorized service center for repair. Always use original  
factory replacement parts when servicing.

SANDING SHEET SELECTION  
WARNING:  
Selecting the correct size grit and type sanding sheet is an  
important step in achieving a high quality 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.  
Always wear safety goggles or safety glasses with side  
shields when operating power tools. Failure to do so  
could result in objects being thrown into your eyes  
resulting in possible serious injury.  
In general, coarse grit will remove the most material and finer  
grit will produce the best finish in all sanding operations. The  
condition of the surface to be sanded will determine which  
grit will do the job. If the surface is rough, start with a coarse  
grit and sand until the surface is uniform. Medium grit may  
then be used to remove scratches left by the coarser grit and  
finer grit used for finishing of the surface. Always continue  
sanding with each grit until surface is uniform.  
WARNING:  
Do not use any attachments or accessories not  
recommended by the manufacturer of this product. The  
use of attachments or accessories not recommended  
can result in serious personal injury.

Gradually lower sa der o to the workpiece so that all of  
the sanding disc surface is in contact with workpiece.  
Extended periods of sanding may overheat the motor. If this  
occurs, turn the sander off and wait until the sanding sheet  
comes to a complete stop. Remove sander from workpiece.  
Remove your hand from vent area. Turn sander on and run  
it free without a load to cool the motor.  
Move the sander slowly across the workpiece using small,  
circular motions.  
Do not force. The weight of the unit supplies adequate  
pressure to do the work. Applying additional pressure only  
slowsthemotor,rapidlywearsthesandingsheet,andgreatly  
reduces sander speed. Excessive pressure will overload the  
motor causing possible damage from overheating and can  
result in inferior work. Any finish or resin on wood may soften  
from the frictional heat. Do not sand on one spot too long  
as the sander’s rapid action may remove too much material,  
making the surface uneven.  
For detail sanding such as corners and crevices, use the tip  
of the sanding sheet with small, back and forth motions.

OPERATION  
EMPTyING THE DUST bAG  
See Figure 7.  
For more efficient operation, empty the dust bag when it is  
no more than half full to permit better air flow through the  
bag. Always empty and clean the dust bag thoroughly upon  
completion of a sanding operation and before storing.  
WARNING:  
Collected dust from sanding surface coatings such as  
polyurethanes, linseed oil, etc. can self-ignite in the  
sander dust bag or elsewhere and cause fire. To reduce  
the risk of fire, empty the dust bag every 10-15 minutes  
while sanding. Never store or leave a sander without  
totally emptying its dust bag. Also follow the recommend-  
ations of the coatings manufacturers.

plastics are susceptible to damage from various types of  
commercial solvents and may be damaged by their use. Use  
clean cloths to remove dirt, dust, oil, grease, etc.  
CLEANING THE SANDING SHEETS  
WARNING:  
The sanding sheets that came with the sander are made to  
be re-used. Therefore, it is important that they be cleaned  
periodically to remove sanding residue and foreign material  
that can accumulate over time.  
Do not at any time let brake fluids, gasoline, petroleum-  
based products, penetrating oils, etc., come in contact  
with plastic parts. Chemicals can damage, weaken or  
destroy plastic which may result in serious personal  
injury.  
To clean sanding sheets, rub the sheets with a hard rubber  
block.  
Electric tools used on fiberglass material, wallboard, spack-  
ling compounds, or plaster are subject to accelerated wear  
and possible premature failure because the fiberglass chips  
and grindings are highly abrasive to bearings, brushes,  
commutators, etc. Consequently, we do not recommend
