Read instruction manual.
Only for EU countries
Do not dispose of electric equipment
together with household waste material!
In observance of European Directive
2002/96/EC on waste electric and elec-
tronic 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.
Intended use
Thetoolisintendedforushtrimmingandprolingof
wood, plastic and similar materials.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. This
tool should be grounded while in use to protect the oper-
ator from electric shock. Use only three-wire extension
cords which have three-prong grounding-type plugs and
three-pole receptacles which accept the tool's plug.
General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and instruc-
tionsmayresultinelectricshock,reand/orserious
injury.
Save all warnings and instruc-
tions 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 atmo-
spheres, such as in the presence of ammable
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.Unmodied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 elec-
tric shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet con-
ditions. 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 inuence of drugs, alcohol or med-
ication. 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 o󰀨-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
yourngerontheswitchorenergisingpowertools
that have the switch on invites accidents.

3ENGLISH
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,jewel-
lery 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 o󰀨. 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
21. Store idle power tools out of the reach of chil-
dren 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 a󰀨ect 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, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
foroperationsdi󰀨erentfromthoseintendedcould
result in a hazardous situation.
Service
25. Have your power tool serviced by a qualied
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 chang-
ing accessories.
27. Keep handles dry, clean and free from oil and
grease.
TRIMMER SAFETY WARNINGS
1. Hold power tool by insulated gripping sur-
faces, because the cutter may contact its own
cord. Cutting a "live" wire may make exposed
metal parts of the power tool "live" and shock the
operator.
2. Use clamps or another practical way to secure
and support the workpiece to a stable plat-
form. Holding the work by your hand or against
the body leaves it unstable and may lead to loss of
control.
3. Wear hearing protection during extended
period of operation.
4. Handle the bits very carefully.
5. Check the bit carefully for cracks or damage
before operation. Replace cracked or damaged
bit immediately.
6. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
7. Hold the tool rmly.
8. Keep hands away from rotating parts.
9. Make sure the bit is not contacting the work-
piece before the switch is turned on.
10. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate improperly
installed bit.
11. Be careful of the bit rotating direction and the
feed direction.
12. Do not leave the tool running. Operate the tool
only when hand-held.
13. Always switch o󰀨 and wait for the bit to come
to a complete stop before removing the tool
from workpiece.
14. Do not touch the bit immediately after opera-
tion; it may be extremely hot and could burn
your skin.
15. Do not smear the tool base carelessly with
thinner, gasoline, oil or the like. They may
cause cracks in the tool base.
16. Use bits of the correct shank diameter suitable
for the speed of the tool.
17. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
18. Always use the correct dust mask/respirator
for the material and application you are work-
ing with.
