GENERAL SAFETY INSTRUCTIONS
WARNING! Read all safety warnings and
all 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. The term “power tool” in the warnings
refers to your mainsoperated (corded) power tool or
battery-operated (cordless) power tool.
1) WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2) ELECTRICAL SAFETY
a. 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.
b. 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.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d. 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.
e. 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.
f. If operating a power tool in a damp
location is unavoidable, use an earth
leakage circuit breaker. Use of an earth
leakage circuit breaker reduces the risk of
electric shock.
3) PERSONAL SAFETY
a. a) 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.
b. b) 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.
c. 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.
d. 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.
e. Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
f. 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.
g. If devices are provided for the connection
of dust extraction and collection facilities,

4
ensure these are connected and properly used.
Use of dust collection can reduce dust-related
hazards.
4) POWER TOOL USE AND CARE
a. 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.
b. 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.
c. 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.
d. 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.
e. 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g. 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 situation.
5) 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.

SAFETY WARNINGS COMMON FOR
SANDING OR POLISHING OPERATIONS
1. This power tool is intended to function as
a sander or polisher. 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.
2. Operations such as grinding, wire
brushing, or cutting-off are not
recommended to be performed with this
power tool. Operations for which the power
tool was not designed may create a hazard
and cause personal injury.
3. Do not use accessories which are not
specifically designed and recommended
by the tool manufacturer. Just because the
accessory can be attached to your power
tool, it does not assure safe operation.
4. The rated speed of the accessory must
be at least equal to the maximum
speed marked on the power tool.
Accessories running faster than their rated
speed can break and fly apart.
5. The outside diameter and the thickness
of your accessory must be within the
capacity rating of your power tool.
Incorrectly sized accessories cannot be
adequately guarded or controlled.
6. The arbour size of wheels, flanges,
backing pads or any other accessory
must properly fit the spindle of the
power tool. Accessories with arbour holes
that do not match the mounting hardware
of the power tool will run out of balance,
vibrate excessively and may cause loss of
control.
7. Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
backing pad for cracks, tear or excess wear,
wire brush for loose or cracked wires. If
power tool or accessory is dropped,
inspect for damage or install an
undamaged accessory. After inspecting
and installing an accessory, position
yourself and bystanders away from the
plane of the rotating accessory and run
the power tool at maximum no-load
speed for one minute. Damaged
accessories will normally break apart during
this test time.
8. Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations . The dust
mask or respirator must be capable of
filtrating particles generated by your
operation. Prolonged exposure to high
intensity noise may cause hearing loss.
9. Keep bystanders a safe distance away
from work area. Anyone entering the
work area must wear personal protective
equipment. Fragments of workpiece or of a
broken accessory may fly away and cause
injury beyond immediate area of operation.
10. Hold power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory
may contact hidden wiring or its own
cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the
power tool "live" and shock the operator.
11. Position the cord clear of the spinning
accessory. If you lose control, the cord may
be cut or snagged and your hand or arm may
be pulled into the spinning accessory.
12. Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the surface
and pull the power tool out of your control.
13. Do not run the power tool while
carrying it at your side. Accidental

6
contact with the spinning accessory could
snag your clothing, pulling the accessory into
your body.
14. Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the
housing and excessive accumulation of
powdered metal may cause electrical
hazards.
15. Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
16. Do not use accessories that require
liquid coolants. Using water or other
liquid coolants may result in electrocution or
shock.
FURTHER SAFETY INSTRUCTIONS FOR
ALL OPERATIONS
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or any
other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in
turn causes the uncontrolled power tool to be
forced in the direction opposite of the accessory’s
rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can dig
into the surface of the material causing the wheel
to climb out or kick out. The wheel may either
jump toward or away from the operator,
depending on direction of the wheel’s
movement at the point of pinching. Abrasive
wheels
may also break under these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking proper
precautions as given below.
1. Maintain a firm grip on the power tool and
position your body and arm to allow you
to resist kickback forces. Always use
auxiliary handle, if provided, for
maximum control over kickback or
torque reaction during start-up. The
operator can control torque reactions or
kickback forces, if proper precautions are
taken.
2. Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
3. Do not position your body in the area
where power tool will move if kickback
occurs. Kickback will propel the tool in
direction opposite to the wheel’s movement
at the point of snagging.
4. Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp
edges or bouncing have a tendency to snag
the rotating accessory and cause loss of
control or kickback.
5. Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of control.
SAFETY WARNINGS SPECIFIC FOR
SANDING OPERATIONS
Do not use excessively oversized sanding
disc paper. Follow manufacturers
recommendations, when selecting sanding
paper. Larger sanding paper extending beyond
the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc or
kickback.
SAFETY WARNINGS SPECIFIC FOR POLISHING
OPERATIONS
Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment
strings. Loose and spinning attachment strings

7
can entangle your fingers or snag on the
workpiece.
SPECIFIC SAFETY RULES
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 and 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, always wear NIOSH/OSHA approved,
properly fitting face mask or respirator when using
such tools
1. Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
2. Keep hands away from rotating parts.
3. Wear eye and hearing protection. Always
use safety glasses. Everyday eyeglasses
are NOT safety glasses.
USE CERTIFIED SAFETY EQUIPMENT.
4. Use of this tool can generate and disburse
dust or other airborne particles, including
wood dust, crystalline silica dust and
asbestos dust. Direct particles away from
face and body. Always operate tool in well
ventilated area and provide for proper dust
removal. Use dust collection system wherever
possible. Exposure to the dust may cause
serious and permanent respiratory or other
injury, including silicosis (a serious lung
disease), cancer, and death. Avoid breathing
the dust, and avoid prolonged contact with
dust. Allowing dust to get into your mouth or
eyes, or lay on your skin may promote
absorption of harmful material. Always use
properly fitting NIOSH/OSHA approved
respiratory protection appropriate for the
dust exposure, and wash exposed areas with
soap and water.

shortest possible cord.
FOREWORD
This Rotary Polisher (also known as a Circular
Polisher) is designed for fast compounding,
polishing, buffing and sanding. The pad spins on
one axis, so much work can be done quickly. In
polishing applications, much heat can be built up
in a small area, which could lead to paint damage.
Therefore, this tool is recommended for use by
professionals only. Anyone new to rotary polishers
should master the craft on scrap car panels,
available at a local salvage yard.
ASSEMBLY
CAUTION: DISCONNECT TOOL FROM POWER
SOURCE.

POLISHING OPERATION
WARNING: If the item to be polished is not
attached to anything and is light enough to be
moved by the spinning polishing pad, it should
be securely clamped or anchored to prevent it
being thrown or flung, resulting in possible
injury.
1. Hold the machine firmly by the main and side
handles, making sure the polishing pad is
clear of foreign objects.
2. Start the machine and lower it at an angle so
that about half of the polishing pad contacts
the work.
3. Move the machine in long continuous
sweeping strokes. DO NOT HOLD POLISHER
IN ONE SPOT Doing so will overheat the
surface and cause swirl marks. It is possible to
damage and burn through the paint very
quickly.
4. Always be sure motor has stopped before
setting the machine down.
MAINTENANCE
Every 50 hours of operation blow compressed
air through the motor while running at no load
to clean out accumulated dust. (If operating in
especially dusty conditions, perform this operation
more often.)
KEEP TOOL CLEAN
Periodically blow out all air passages with dry
compressed air. All plastic parts should be cleaned
with a soft damp cloth. NEVER use solvents to
clean plastic parts. They could possibly dissolve or
otherwise damage the material.
Wear safety glasses while using compressed air.
FAILURE TO START
Should your tool fail to start, check to make sure
the prongs on the cord plug are making good
contact in the outlet. Also, check for blown fuses or
open circuit breakers in the line
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
NOTE: Checking and replacing the carbon
brushes should be entrusted to a qualified
service center.
The carbon brushes furnished will last
approximately 50 hours of running time or 10,000
on/off cycles. Replace both carbon brushes when
either has less than 1/4" length of carbon
remaining.
To inspect or replace brushes, first unplug the
machine.
Caution: Always replace the brushes as a
pair
TO REPLACE
simply remove the brush caps and withdraw the
old brushes. Replace with new brushes (always
replace as a pair) ensuring that they align
properly and slide freely. Then replace the brush
caps.

10
NOTE: To reinstall the same brushes, first make
sure the brushes go back in the way they came
out. Otherwise a break-in period will occur that
will reduce motor performance and increase
brush wear.
If the replacement of the power supply
cord is necessary, this has to be done by the
manufacturer or their agent in order to avoid a
safety hazard.
WARNING: All repairs must be entrusted to an
authorized service center. Incorrectly performed
repairs could lead to injury or death.
