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.

Work area safety

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

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 safety

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 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

3

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.

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to grinder safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal
injury.

1. Safety Warnings Common for Grinding,
Sanding, Wire Brushing, or Abrasive
Cutting-Off Operations:

2. This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool.
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.

3. Operations such as polishing 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.

4. 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.

5. 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.

6. 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.

7. The arbour size of wheels, flanges, 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.

8. Do not use a damaged accessory. Before each

use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. 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.

9. 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 abrasive or
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.

10. 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.

11. 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.

12. Position the cord clear of the spinning
accessory. If you lose control, the cord may be
