WARNING: Some dust created by power sanding, sawing, grinding, drilling and
other construction activities contains chemicals known to cause cancer, birth
defects or other reproductive harm. 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 exposure to these chemicals, work in a well-ventilated area
and work with approved safety equipment such as those dust masks that are
specially designed to filter out microscopic particles.
WARNING: To avoid electrical hazards, fire hazards or damage to the pad
sander, use proper circuit protection.
The pad sander is wired at the factory for 120 V operation. It must be connected to a
120 V, 15 A time delayed fuse or circuit breaker. If the power cord is damaged, it
must be replaced by a similar cord or a special joint supplied by the manufacturer or
by its authorized service agent.

GENERAL POWER TOOL SAFETY
WARNINGS
WARNING: Read all safety
warnings and instructions. Failure to
follow the warnings and instructions may
result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for
future reference.
WORK AREA SAFETY
Keep your 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.
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 type 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). Use of a
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 dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.

PERSONAL SAFETY –cont’d
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.
Remove any adjusting key or wrench
before turning the power tool on. A
wrench or key that is 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 jewelry. Keep your hair,
clothing and gloves away from moving
parts. Loose clothing, 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 properly and used. Use of
dust collection can reduce dust-related
hazards.
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 when used 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 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 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 power tools with sharp
cutting edges are less likely to bind and are
easier to control.
Use the power tool, accessories and 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 condition.
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.
POWER TOOL SAFETY

Make sure your extension cord is the
proper size. When using an extension
cord, be sure to use one heavy enough to
carry the current the tool will draw. An
undersized cord will cause a drop in line
voltage resulting in loss of power and
overheating. The table on at right shows
the correct size to use according to cord
length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The
smaller the gauge number the heavier the
cord.
Be sure your extension cord is properly
wired and in good condition. Always
replace a damaged extension cord or have
it repaired by a qualified electrician before
using it. Protect your extension cord from
sharp objects, excessive heat and damp or
wet areas.
Use a separate electrical circuit for your
power tools. This circuit must not be less
than 14 gauge wire and should be
protected with either a 15A time delay fuse
or circuit breaker. Before connecting the
power tool to the power source, make sure
the switch is in the OFF position and the
power source is the same as indicated on
the nameplate. Running at lower voltage
will damage the motor.
WARNING: Repair or replace
damaged or worn extension cords
immediately.
Select the appropriate extension cord
gauge and length using the chart below.
When operating a power tool outdoors,
use an outdoor extension cord marked
“W-A” or “W”. These cords are rated for
outdoor use and reduce the risk of electric
shock.
WARNING: Keep the extension
cord clear of the working area. Position
the cord so it will not get caught on the
workpiece, tools or any other
obstructions while you are working with
the power tool.

WARNING: Always wear safety
goggles or safety glasses with side
shields when operating your sander.
Failure to do so could result in foreign
objects being thrown into your eyes
resulting in possible serious eye
damage.
Always wear an appropriate dust mask
and hearing protection when using your
sander.
SANDPAPER SELECTION
Selecting the correct grit and type of
sandpaper is extremely important 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 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 best 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. Fine grit
should be used for finishing the surface.
Always continue sanding with each grit until
the surface is uniform.
Have you read “POWER TOOL
SAFETY”, “PAD SANDER
SAFETY”, “GUIDELINES FOR
EXTENSION CORDS” and
“SYMBOLS” on pages 3, 4, 5 and
6 of this Manual? If not, please do
so now before you operate this
sander. Your safety depends on it!
Every time you use the sander
you should verify the following:
1. Sander cord is not damaged.
2. Safety glasses and dust mask
are being worn.
3. Sandpaper is the correct type
for the job.
4. Sandpaper is in good
condition and properly
installed.
Failure to adhere to these safety
rules can greatly increase the
chances of injury.

SANDING
Clamp or otherwise secure your workpiece
to prevent it from moving under the sander
while being sanded.
WARNING: Unsecured workpiece
could be thrown toward the operator
causing injury.
Place sander on the workpiece so that the
complete sandpaper surface is in contact
with the workpiece. Turn the sander ON by
pressing on the side of the ON/OFF switch.
Move the sander slowly over workpiece
making successive passes in parallel lines,
circles or crosswise movements. Because
the orbital motion of the sanding pad moves
in tiny circles, it is not necessary to move
the sander with the grain or in the same
direction for successive passes (see
Fig. 5).
Upon completion of the sanding operation,
turn sander OFF by pressing on the other
side of the ON/OFF switch. Wait until the
sanding pad comes to a complete stop
before removing from the workpiece.
WARNING: Your sander should only
be turned ON when the entire surface of
the sanding pad is in contact with the
workpiece. Failure to follow this
sanding procedure could result in loose
sandpaper which could result in
possible injury.
NOTE: Hold the sander using the pad
grip on top of the sander. Be careful
NOT to cover the cooling vents with
your hand. Motor damage may occur
from over heating if the cooling vents
are covered.
DO NOT FORCE THE SANDER. The
weight of the sander usually provides
adequate pressure. Let the sander and
sandpaper do the work. Applying added
pressure will slow the motor, increase the
wear on the sandpaper and greatly reduce
sander speed. Motor damage may occur if
excessive downward pressure is applied. It
will also create an inferior finish on sanded
work. Any finish or resin on wood will soften
from the frictional heat, causing sandpaper
to become clogged quickly. Do not sand in
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, wait until the sanding pad
comes to a complete stop and remove it
from the workpiece. Check to make sure
your hand has not been covering the
cooling vents. Let the motor cool before
continuing sanding operation.

WARNING: When servicing, use
only identical original equipment parts.
Use of any other part may create a
hazard or cause product damage.
CLEANING
DO NOT use solvents when cleaning
plastic parts. Most plastics are susceptible
to damage from various types of
commercial solvents and may be damaged
by their use. Use clean cloth to remove dirt,
dust, oil, grease, etc.
WARNING: Do not at any time
allow brake fluids, gasoline, petroleum-
based products, penetrating oils, etc. to
come in contact with plastic parts. They
contain chemicals that can damage,
weaken or destroy plastic.
It has been found that electric tools are
subjected to accelerated wear and possible
premature failure when they are used on
fiberglass boats and sports cars, wallboard,
spackling compounds or plaster. The chips
and grindings from these materials are
highly abrasive to electric tool parts such as
bearings, brushes, commutators, etc.
Consequently, it is not recommended that
this tool be used for extended work on any
fiberglass material, wallboard, spackling
compounds or plaster. During any use on
these materials it is extremely important
that the tool is cleaned frequently by
blowing out with an air jet.
WARNING: Always wear safety
goggles or safety glasses with side
shields during all sanding operations. It
is critical that you also wear safety
goggles or safety glasses with side
shields and a dust mask while blowing
dust out of the sander with an air jet.
Failure to take these safety precautions
could result in permanent eye or lung
damage.
LUBRICATION
All of the bearings in this sander are
lubricated with a sufficient amount of high
grade lubricant for the life of the unit under
normal conditions. Therefore, no further
lubrication is required.
