General Power Tool Safety
Warnings
WARNING Read al l saf ety warni ngs and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
Do not dispose of electric equipment
together with household waste material!
In observance of European Directive
2002/96/EC on waste electric and
electronic equipment and its
implementation in accordance with
national law, electric equipment that
have reached the end of their life must
be collected separately and returned to
an environmentally compatible recycling
facility.
ENE052-1
ENF002-2
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. Avoi d b ody c onta ct with earthed or grou nded
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.
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
GEA005-3

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 residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always
recommended.
Personal safety
11. 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.
12. 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.
13. 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 to ols wi th
your finger on the switch or energising power tools
that have the switch on invites accidents.
14. Remove any adjusting key or wrench before
turning the power tool on. A w renc h or a k ey l eft
attached to a rotating part of the power tool may
result in personal injury.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16. 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.
17. 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
18. 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.
19. Do not use the power tool if the switch does
not turn it on and off. Any po wer tool that cannot
be controlled with the switch is dangerous and
must be repaired.
20. 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.
21. 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.
22. 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.
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. 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
25. 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.
26. Follow instruction for lubricating and
changing accessories.
27. Keep handles dry, clean and free from oil and
grease.

BELT SANDER SAFETY
WARNINGS
1. Hold power tool by insulated gripping
surfaces, because the belt may contact its own
cord. Cutting a "live" wire may make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.
2. Ventilate your work area adequately when you
perform sanding operations.
3. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.
4. Always use the correct dust mask/respirator
for the material and application you are
working with.
5. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT safety
glasses.
6. Hold the tool firmly with both hands.
7. Make sure the belt is not contacting the
workpiece before the switch is turned on.
8. Keep hands away from rotating parts.
9. Do not leave the tool running. Operate the tool
only when hand-held.
10. This tool has not been waterproofed, so do not
use water on the workpiece surface.
SAVE THESE INSTRUCTIONS.

CAUTION:
• The tool should not be in contact with the workpiece
surface when you turn the tool on or off. Otherwise
a poor sanding finish or damage of the belt may
result.
Hold the tool firmly with both hands. Turn the tool on and
wait until it attains full speed. Then gently place the tool
on the workpiece surface. Keep the belt flush with the
workpiece at all times and move the tool back and forth.
Never force the tool. The weight of the tool applies
adequate pressure. Excessive pressure may cause
stalling, overheating of the motor, burning of the
workpiece and possible kickback.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
