ELECTRICAL SAFETY
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 120V AC operation. It must be connected
to a 120V AC, 15 A circuit that is protected by a time-delayed fuse or circuit
breaker. To avoid shock or fire, replace power cord immediately if it is worn,
cut or damaged in any way.
GENERAL SAFETY WARNINGS
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals that are
known to cause cancer, birth defects, or other genetic abnormalities. These
chemicals include:
Lead from lead-based paints
Crystalline silica from bricks, cement, and other masonry products
Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies, according to how
often this type of work is performed. In order to reduce exposure to these
chemicals, work in a well-ventilated area, and use approved safety
equipment, such as a dust mask that is specifically designed to filter out
microscopic particles.

GENERAL SAFETY RULES
WARNING: Read and understand all
instructions. Failure to follow all instructions
listed below may result in electric shock, fire
and/or serious personal injury.
WORK AREA
Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
Do not operate power tools in potentially
explosive environments, such as in the
presence of flammable liquids, gas or dust.
Power tools create sparks that may ignite dust
or fumes.
Keep bystanders, children and visitors away
while operating the tool. Distractions can cause
the operator to lose control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will only fit into a polarized plug
one way.
If the plug does not fit into the outlet properly,
reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet.
Do not alter the plug in any way. Double
insulation eliminates the need for the three-
pronged grounded power cord and grounded
power supply system.
Avoid contact between the operator's body and
grounded surfaces such as pipes, radiators,
ranges, and refrigerators. There is an increased
risk of electric shock if the operator's body is
grounded.
Do not expose power tools to rain or wet
conditions. Water entering the power tool will
increase the risk of electric shock.
Do not abuse the cord. Do not use the power
cord to carry the tool or to pull the plug out of
the outlet. Keep the power cord away from heat,
oil, sharp edges, and moving parts. Replace a
damaged power cord immediately. A damaged
power cord increases the risk of electric shock.
When operating a power tool outdoors, use an
outdoor-rated extension cord type
“W-A” or “W”. These cords are rated for outdoor
use and they reduce the risk of electric shock.
PERSONAL SAFETY
Stay alert, be aware of the surroundings, and
use common sense when operating a power
tool. Do not use a power tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating a power tool may result in serious
personal injury.
Dress properly. Do not wear loose clothing or
jewellery.
Contain long hair. Keep hair, clothing, and
gloves away from moving parts. Loose clothing,
jewellery, or long hair can get caught in moving
parts.

PERSONAL SAFETY –cont’d
Avoid accidental start-ups. Verify that the switch
is in the OFF position before plugging in the
tool. Carrying a power tool with a finger on the
switch or plugging in a tool that has the switch in
the ON position invites accidents.
Remove adjusting keys and wrenches before
turning the tool ON. A wrench or key that is left
attached to a rotating part of the tool may result
in personal injury.
Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
allows the operator to maintain better control of
the tool in unexpected situations.
Use safety equipment. Always wear eye
protection.
Use a dust mask, non-skid safety shoes, a
hardhat, or hearing protection when appropriate.
USE AND CARE OF POWER TOOLS
Use clamps or another practical means to
secure and support the workpiece to a stable
platform. Holding the work in a hand or against
the body is not stable, and may lead to loss of
control.
Do not force the tool. Use the correct tool for the
application. The correct tool will do the job better
and safer when used at the rate that it was
designed to work at.
Do not use a power tool if it cannot be turned
ON or OFF using the power switch. A tool that
cannot be controlled using the switch is
dangerous, and must be repaired.
Disconnect the plug from the outlet before
making any adjustments, changing accessories,
or storing the tool. Such preventive safety
measures reduce the risk of accidental start-
ups.
When power tools are not in use, store them out
of the reach of children or untrained persons.
Tools are dangerous in the hands of untrained
users.
Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to
bind, and are easier to control.
Inspect the tool for misalignment or binding of
moving parts, broken parts, and any other
condition that may affect the operation of the
tool. If it is damaged, have the tool serviced
before using it. Many accidents are caused by
poorly maintained tools.
Use only accessories that are recommended by
the manufacturer for this model. Accessories
that are suitable for one tool may become
hazardous when used with another tool.
SERVICE
Tool servicing must be performed by qualified
personnel. Service or maintenance performed
by non-qualified personnel could result in a risk
of injury.
When servicing a tool, use only identical
replacement parts. Follow the instructions in the
Maintenance section of this Manual. The use of
unauthorized parts or failure to follow the
instructions in the Maintenance section of this
Manual may create a risk of electric shock or
injury.

as well as the specific potential hazards
related to this tool. Following this rule will
reduce the risk of electric shock, fire or serious
injury.
Always wear eye protection. Any
power tool can throw foreign
objects into your eyes and cause
permanent eye damage.
ALWAYS wear safety goggles (not glasses) that
comply with ANSI safety standard Z87.1.
Everyday glasses have only impact resistant
lenses. They ARE NOT safety glasses.
WARNING: Wearing glasses or goggles
that do not comply with ANSI Z87.1 could
cause serious injury if they break.
Always wear hearing protection and a dust
mask when sanding. Use only in a well-
ventilated area. Using personal safety devices
and working in a safe environment reduces the
risk of injury.
WARNING: Always unplug the tool from
the power source before changing the
sanding disc or buffing pad and when
cleaning the tool.
Do not wear gloves, neckties or loose clothing.
Secure workpiece. Use clamps or a vice to hold
the work when practical. It is safer than using
your hand and it frees both hands to operate the
tool.
Do not sand material too small to be securely
held.
Make sure there are no nails or foreign objects
in the part of the workpiece to be sanded.
Always keep hands out of the path of the
sanding pad. Avoid awkward hand positions
where a sudden slip could cause your hand to
move into the path of the sanding pad.
To avoid injury from accidental starting, always
remove the plug from the power source before
installing or removing a sandpaper or dust box.

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.

1. The sander cord is not damaged.
2. Sander and sanding disc are the
correct type for the job.
3. Sanding disc is in good condition.
4. Safety glasses, hearing protection
and dust mask are being worn.
Failure to observe these safety rules will
significantly increase the risk of injury.
WARNING
!

13
SANDING DISC SELECTION –cont’d
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 most material.
Fine 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.
NOTE: Where the sanding disc grits are shown
numerically, higher numbers indicate finer grit
and lower numbers indicate coarser grit.
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.
SANDING
Clamp or otherwise secure your workpiece to
prevent it from moving under the sander while
being sanded. Secure the workpiece in a vice if
possible.
WARNING: Any unsecured workpiece could
be thrown toward the operator causing injury.
Set the speed control to the desired speed.
Higher speeds tend to cut faster and produce a
smoother finish. Place the sander on the
workpiece so the complete sanding disc surface
is in contact with the workpiece. Turn the sander
ON by pressing on the right hand side of the
ON/OFF switch. Move the sander slowly over
workpiece making successive passes in parallel
lines, circles or crosswise movements. Because
the random orbital motion of the sanding disc
moves in tiny circles, it is not necessary to move
the sander with the grain or in the same
direction for successive passes (Fig. 7).
NOTE: Hold the sander using the handle (1) on
top of the sander (Fig. 8). Be careful NOT to
cover the cooling vents (2) with your hand.
Covering the cooling vents could cause the
motor to be damaged by overheating.

SANDING –cont’d
DO NOT FORCE THE SANDER. The weight of
the sander usually provides adequate pressure.
Let the sander and the sanding disc do the
work. Applying added pressure will slow the
motor, increase the wear on the sanding disc
and greatly reduce the sander speed. Excessive
pressure will overload the motor causing
possible damage from the motor overheating. It
will also create an inferior finish on sanded
work. Any finish or resin on wood will soften
from the frictional heat, causing sanding disc 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 disc comes to a
complete stop and remove it from the
workpiece. Check to make sure your hands
have not been covering the cooling vents.
Remove the plug from the power source and let
the motor cool before continuing the sanding
operation. Check to make sure the motor
cooling vents are not blocked with sanding dust.
Upon completion of the sanding operation, turn
sander OFF by pressing on the left side of the
ON/OFF switch. Wait until the sanding disc
comes to a complete stop before removing it
from the workpiece.
WARNING: Your sander should only be
turned ON when the entire surface of the
sanding disc is in contact with the workpiece.
Failure to follow this sanding procedure could
result in a loose sanding disc, which could result
in possible injury.
GENERAL
WARNING: When servicing, use only
identical replacement parts. The use of any
other part may create a hazard or cause
product damage.
DO NOT use solvents when cleaning plastic
parts. Plastics are susceptible to damage from
various types of commercial solvents and may
be damaged by their use. Use a clean cloth to
remove dirt, dust, oil, grease etc.
WARNING: Do not allow brake fluids,
gasoline, petroleum-based products,
penetrating oils, etc. to come into contact
with plastic parts. They contain chemicals
that can damage, weaken or destroy plastic.
Remove accumulated dust and debris regularly
using a soft DRY brush.
WARNING: Use safety goggles when
using an air jet to blow dust out of the
sander.
DO NOT abuse power tools. Abusive practices
can damage the tool and the workpiece.
WARNING: DO NOT attempt to modify
tools or create accessories. Any such
alteration or modification is misuse and
could result in a hazardous condition leading
to possible serious injury. It will also void
the warranty.
LUBRICATION
All of the bearings in this tool 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.
