tions for future reference.
1. Be familiar with the controls and proper use of
the equipment.
2. Cutting elements continue to rotate after the
motor is switched o󰀨.
3. Never allow children or people unfamiliar with
the instructions to use the machine. Local reg-
ulations may restrict the age of the operator.
4. Stop using the machine while people, espe-
cially children, or pets are nearby.
5. Only use the machine in daylight or good
articial light. Avoid using the machine in bad
weather conditions especially when there is a
risk of lightning.
6. Before using the machine and after any

tted for trimming the lament line length.
After extending new cutter line always return
the machine to its normal operating position
before switching on.
8. Never t metal cutting elements.
9. This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they
have been given supervision or instruction
concerning use of the appliance by a person
responsible for their safety. Children should be
supervised to ensure that they do not play with
the appliance.
10. Use the tool with the utmost care and
attention.
11. Operate the tool only if you are in good phys-
ical condition. Perform all work calmly and
carefully. Use common sense and keep in mind
that the operator or user is responsible for
accidents or hazards occurring to other people
or their property.
12. Never operate the tool when tired, feeling ill or
under the inuence of alcohol or drugs.
13. The tool should be switched o󰀨 immediately if
it shows any signs of unusual operation.
14. Keep ngers away from switch trigger when
not operating the tool and when moving from
one operating position to another.
Intended use of the tool
1. Use right tool. The cordless grass trimmer is
only intended for cutting grass, light weeds. It
should not be used for any other purpose such
as hedge cutting as this may cause injury.
Personal protective equipment
►Fig.1
►Fig.2
1. Dress Properly. The clothing worn should be
functional and appropriate, i.e. it should be
tight-tting but not cause hindrance. Do not
wear either jewelry or clothing which could
become entangled with high grass. Wear pro-
tective hair covering to contain long hair.
2. When using the tool, always wear sturdy shoes
with a non-slip sole. This protects against
injuries and ensures a good footing.
3. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.
Electrical and battery safety
1. Avoid dangerous environment. Don't use the
tool in damp or wet locations or expose it to
rain. Water entering the tool will increase the
risk of electric shock.
2. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of
re when used with another battery pack.
3. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
4. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a re.

9ENGLISH
5. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, seek medical help. Liquid
ejected from the battery may cause irritation or
burns.
6. Do not dispose of the battery(ies) in a re. The
cell may explode. Check with local codes for
possible special disposal instructions.
7. Do not open or mutilate the battery(ies).
Released electrolyte is corrosive and may
cause damage to the eyes or skin. It may be
toxic if swallowed.
8. Do not charge battery in rain, or in wet
locations.
Starting up the tool
►Fig.3
1. Make sure that there are no children or other
people within a working range of 15 meters
(50 ft), also pay attention to any animals in the
working vicinity. Otherwise stop using the tool.
2. Before use always check that the tool is safe
for operation. Check the security of the cutting
tool and the guard and the switch trigger/lever
for easy and proper action. Check for clean
and dry handles and test the on/o󰀨 function of
the switch.
3. Check damaged parts before further use of
the tool. A guard or other part that is damaged
should be carefully checked to determine
that it will operate properly and perform its
intended function. Check for alignment of
moving parts, binding of moving parts, break-
age of parts, mounting, and any other condi-
tion that may a󰀨ect its operation. A guard or
other part that is damaged should be properly
repaired or replaced by our authorized ser-
vice center unless indicated elsewhere in this
manual.
4. Switch on the motor only when hands and feet
are away from the cutting tool.
5. Before starting make sure that the cutting
tool has no contact with hard objects such as
branches, stones etc. as the cutting tool will
revolve when starting.
6. Make sure there are no electrical cables, water
pipes, gas pipes etc. that could cause a hazard
if damaged by use of the tool.
Method of operation
1. Never operate the machine with damaged
guards or without the guards in place.
2. Only use the tool in good light and visibility.
During the winter season beware of slippery
