GENERAL POWER TOOL SAFETY WARNINGS
(For All Power Tools)
WARNING! Read and understand all instructions.
Failure to follow all instructions listed below may result in electric
shock, fire and/or serious personal injury.
Save all warnings and instructions for future reference.
The term “power tool”in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
Work Area Safety
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
4. Power tool plugs must match the outlet. Never modify the plug in
anyway. Do not use any adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
5. Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk o electric
shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
7. 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.
8. 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.
9. If operating a power in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
NOTE: The term “residual current device (RCD)” may be replaced by the term
“ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
Personal Safety
10.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.
11.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.
12.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.
13.Remove any adjusting key or wrench before turning the tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
14.Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
15.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.
16.If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Power Tool Use and Care
17.Do not force the power tool. Use the correct power tool for your
-1- -2-

application. The correct power tool will do the job better and safer at the rate
for which it was designed.
18. Do not use tool if switch does not turn it on or off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
19. 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.
20. 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.
21. 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.
22. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
23. 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.
Service
24. 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.
VOLTAGE WARNING:
Before connecting the machine to a power source (receptacle, outlet, etc.), be
sure the voltage supplied is the same as that specified on the nameplate of the
machine. A power source with voltage greater than that specified for the machine
can result in SERIOUS INJURY to the user, as well as damage to the machine. If
in doubt, DO NOT PLUG IN THE MACHINE. Using a power source with voltage
less than nameplate rating is harmful to the motor.

Installing or Removing Abrasive Paper
CAUTION:
Always be sure that the tool is
switched off and unplugged before
installing or removing the paper.
To install the abrasive paper, first turn
the lever clip to the position showed in
Fig.1.
Then insert one paper end between
the base and the paper clamp and
keep paper end parallel with the base
side. (Fig.2)
Once inserted well, return the lever
clip to the original position. Overcast
the pad with the paper and repeat the
same process for the other end of the
base, maintaining the proper paper
tension. (Fig.3)
Make sure the abrasive paper is
clamped securely or the sanding
maybe uneven caused by loosen or sliding of abrasive paper.
Switch Operation
CAUTION:
Before plugging in the tool, always check
to see that the trigger switch actuates
properly and returns to the “OFF”position
when released.
To start the tool, simply pull the trigger.
Release the trigger to stop. For continuous
operation, pull the trigger and then push in
the lock button. To stop the tool from the
locked position, pull the trigger fully, and
then release it. (Fig. 4)
Sanding Operation
Hold the tool firmly. Turn the tool on and
wait until it attains full speed. Then gently
place the tool on the workpiece surface.
Keep the pad flush with the workpiece and
apply slight pressure on the tool. (Fig. 5)
An orbital sander is generally used to
remove only a small amount of material at
a time. Since the quality of the surface is
more important than the amount of stock
removed, do not bear down on the tool.
You can put a high polish on furniture or other fine surfaces by using a cloth under the
tool.
CAUTION:
Do not block motor vent with your finger or hand.
Never run the tool without paper. You may seriously damage the pad.
Never force the tool. Excessive pressure may decrease the sanding efficiency,
