GENERAL SAFETY RULES GEA001-3

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 battery­operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Wor k a re a sa fe ty

1. Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

2. Do not operate power tools in explosive atmos-

pheres, 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 oper-

ating 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 condi-

tions. 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.

Personal safe ty

9. 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.

10. 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.

11. 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.

12. 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.

13. Do not overreach. Keep proper footing and bal­ance at all times. This enables better control of the

power tool in unexpected situations.

14. 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.

15. 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.

Power tool use and care

16. 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.

17. 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.

18. Disconnect the plug from the power source and/
or the battery pack from the power tool before

3

making any adjustments, changing accessories,
or storing power tools. Such preventive safety

measures reduce the risk of starting the power tool
accidentally.

19. 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.

20. 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.

21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

22. 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 those
intended could result in a hazardous situation.

Service

23. 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.

24. Follow instruction for lubricating and changing
accessories.

25. Keep handles dry, clean and free from oil and
grease.

GEB021-1

5. This tool has not been waterproofed, so do not
use water on the workpiece surface.

6. Ventilate your work area adequately when you
perform sanding operations.

7. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala­tion and skin contact. Follow material supplier
safety data.

8. Use of this tool to sand some products, paints
and wood could expose user to dust containing
hazardous substances. Use appropriate respi­ratory protection.

9. Be sure that there are no cracks or breakage on
the pad before use. Cracks or breakage may
cause a personal injury.

SAVE THESE INSTRUCTIONS.

WARNING:

MISUSE or failure to follow the
safety rules stated in this instruction
manual may cause serious personal
injury.

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.

1. Hold power tools by insulated gripping sur­faces when performing an operation where the
cutting tool may contact hidden wiring or its
own cord. Contact with a “live” wire will make

exposed metal parts of the tool “live” and shock the
operator.

2. Always use safety glasses or goggles. Ordinary
eye or sun glasses are NOT safety glasses.

3. Hold the tool firmly.

4. Do not leave the tool running. Operate the tool
only when hand-held.
