General Power Tool Safety
Warnings
GEA005-3
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.
2
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.
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 30 mA 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 tools with 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 wrench or a key left
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 power 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.

Lapping (grinding) blade
• When the cylinder blade loses sharpness, perform
lapping (grinding) in the following way. Note that
lapping is a simple form of sharpening, so it will not
restore the blades to their new state. If the cylinder
blade and/or the fixed blade is/are worn down greatly,
replace both cylinder and fixed blades as one set.
• The leading edges of the spiral-shaped blades on the
cylinder blade are coated in red paint. It is
recommended that the cylinder blade be replaced once
these red sections disappear. (As a rule, this is after
two or three lapping sessions.)
