General Power Tool Safety
Warnings
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
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 any way. 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 of
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.

3
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 tool in a damp location is
unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
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 power 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 application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
18. 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.
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.
25. Follow instruction for lubricating and
changing accessories.
26. Keep handles dry, clean and free from oil and
grease.

SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to sander safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal
injury.
Safety Warnings Common for Sanding Operation:
1. This power tool is intended to function as a
sander. 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.

4
2. Operations such as grinding, wire brushing,
polishing 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 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 backing
pad for cracks, tear or excess wear. 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 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 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.
17. Kickback and Related Warnings
Kickback is a sudden reaction to a snagged
rotating backing pad or any other accessory.
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.
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.
a) 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.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) 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.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging

5
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
e) 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:
18. 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.
19. Check the backing pad carefully for cracks,
damage or deformity before operation.
Replace cracked, damaged or deformed pad
immediately.
20. NEVER use tool with wood cutting blades or
other sawblades. Such blades when used on a
sander frequently kick and cause loss of
control leading to personal injury.
21. Hold the tool firmly.
22. Keep hands away from rotating parts.
23. Make sure the abrasive disc is not contacting
the workpiece before the switch is turned on.
24. When sanding metal surfaces, watch out for
flying sparks. Hold the tool so that sparks fly
away from you and other persons or
flammable materials.
25. Do not leave the tool running. Operate the tool
only when hand-held.
26. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
27. Check that the workpiece is properly
supported.
28. Pay attention that the wheel continues to
rotate after the tool is switched off.
29. This tool has not been waterproofed, so do not
use water on the workpiece surface.
30. Ventilate your work area adequately when you
perform sanding operations.
31. Use of this tool to sand some products, paints
and wood could expose user to dust
containing hazardous substances. Use
appropriate respiratory protection.
32. Always be sure that the tool is switched off
and unplugged before carrying out any work
on the tool.
33. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure
operator safety.
34. Do not use the tool on any materials
containing asbestos.
35. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.
36. Always use the correct dust mask/respirator
for the material and application you are
working with.
37. Ensure that ventilation openings are kept clear
