GENERAL SAFETY RULES
WARNING!
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 warnings listed below
refers to your mains operated (corded) power tool or
battery operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit.
Cluttered and 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 of 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.
3) Personal safety
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) Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal
injuries.
c) Avoid accidental starting. Ensure the switch is in the
off position before plugging in.
Carrying power tools with your finger on the
switch or plugging in 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
jewellery. Keep your hair, clothing and gloves away
from moving parts.
Loose clothes, jewellery or long hair can be caught
in moving parts.
g) 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.
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 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 tools
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 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 different from
intended could result in a hazardous situation.
5) Service
a) 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.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.

1. Mounting
(1) Attach the washer nut on the rubber pad.
(2) While pushing the lock lever with one hand, lock the
spindle by turning the rubber pad slowly with the
other hand.
Tighten the washer nut by using the supplied wrench.
(3) Cover the rubber pad with the wool bonnet. (optional
accessory)
Pull the string of the wool bonnet, (optional accessory)
let it contact the rubber pad, and tie the string up.
Then, tuck the knot and the remainder of the string
into the wool bonnet. (optional accessory) (See Fig.

CAUTION
䡬 Improper fitting of the wool bonnet may cause
vibration.
䡬 Confirm that the lock lever is disengaged by pushing
lock lever two or three times before switching the
polisher on.
2. Dismounting
To remove the wool bonnet, follow the above
precedures in reverse.
PRACTICAL POLISHER APPLICATIONS
1. Curved surface as well as plain one is treated for
finishing. It is recommended to hold the polisher
without pushing on the material, and make the best
of the weight of the machine alone. As the excessive
pressure on the polishing surface will not only bring
unsatisfactory result but also apply overload on the
motor.
CAUTION
When using the tool at any value except the full
speed (Dial scale 6), the motor cannot be sufficiently
cooled due to the decreased number of revolution.
This could result in the risk of burning and damaging
the motor before an overload protective mechanism
starts to function.
Make sure that you use the tool by lightly applying
it to the surface of material when you use it at any
value except the full speed (Dial scale 6).
2. Depending on the finishing degree of the surface,
use the polishing compound or wax. In order to
attain the maximum polishing effect, first polish the
surface with the fine sand paper using the sander,
than polish it with the polishing compound using the
wool bonnet, and than finish with wax. Apply a small
quantity of the compound and wax to the surface,
and polish with the wool bonnet.
3. Don’t let the cord touch the wool bonnet during its
operation, for the rotating wool bonnet may catch
the cord and get caught it in.
4. Switching on the polisher
Pulling the trigger of switch and push the stopper, it
keeps the switched-on condition and it is convenient
for the continuous operation. When switched off, the
stopper can be disengaged by means of pulling the
trigger again.
5. Precaution after use
Do not lay the polisher down immediately after using
on a place where there are many shavings, much dirt
and dust until it has completely stopped revolving.
CAUTION
When the polisher is not in use, the power source
should be disconnected.
MAINTENANCE AND INSPECTION
1. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
2. Maintenance of the motor
The motor unit winding is the very “heart” of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
3. Inspecting the carbon brushes (Fig. 5)
The Motor employs carbon brushes which are consumable parts. When they become worn to or near
the “wear limit”, it could result in motor trouble.
When an auto-stop carbon brush is equipped, the
motor will stop automatically. At that time, replace
both carbon brushes with new ones which have the
same carbon brush Number shown in the figure.
In addition, always keep carbon brushes clean and
ensure that they slide freely within the brush holders.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
