SAVE THESE INSTRUCTIONS.
General instructions
1. Do not allow persons unfamiliar with the string
trimmer or these instructions to operate the
tool. String trimmers are dangerous in the hands
of untrained users.
2. Be sure that anyone who is to operate the
string trimmer has rst read the instruction
manual.
3. Use the string trimmer with the utmost care
and attention.
4. Operate the string trimmer only if you are in
good physical 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.
5. Never operate the string trimmer when tired,
feeling ill or under the inuence of alcohol or
drugs.
6. Avoid accidentally starting:
— Ensure the switch is in the off posi-
tion before installing the battery pack.
Inserting the battery pack into the string
trimmer with the switch on invites accidents.
— Carrying the string trimmer with your
nger on the switch invites accidents.
7. The string trimmer should be switched off
immediately if it shows any signs of abnormal
operation.
8. Disconnect the battery from the string trimmer
before making any adjustments, changing
accessories or storing. Such preventive safety
measures reduce the risk of starting the sting
trimmer accidentally.
9. Don't force the tool. It will do the job better and
with less likelihood of a risk of injury at the rate for
which it was designed.
10. Don't overreach. Keep proper footing and
balance at all times.
11. Stay Alert - Watch what you are doing. Use
common sense. Do not operate appliance
when you are tired.
12. Store idle appliances indoors.
Intended use of the tool
1. Use right tool. The cordless string trimmer
is only intended for cutting grass and light
weeds. It should not be used for any other
purpose such as edging or hedge cutting as
this may cause injury.
2. Use only the manufacturer’s recommended
accessories and attachments. Use of any other
accessories and attachments may increase the
risk of injury.
Personal protective equipment
1. Dress Properly. The clothing worn should be
functional and appropriate, i.e. it should be

3. Always wear a helmet where there is a risk of
falling objects. The protective helmet is to be
checked at regular intervals for damage and
is to be replaced at least every ve years. Use
only approved protective helmets.
4.
Use safety glasses. The visor of the helmet (or alter-
natively goggles) protects the face from ying debris
and stones. During operation of the tool always wear
goggles, or a visor to prevent eye injuries.
5. Wear adequate noise protection equipment
to avoid hearing impairment (ear muffs , ear

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 specied 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 specically 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.
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.

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 nylon
cutting head and the guard and the switch
trigger/lever for easy and proper action. Check
for clean and dry handles and test the on/off
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

other part that is damaged should be properly
repaired or replaced by our authorized service center unless indicated elsewhere in this
manual.
4. Switch on the motor only when hands and feet
are away from the nylon cutting head.
4 ENGLISH
5. Before starting make sure that the nylon cutting head has no contact with hard objects
such as branches, stones etc. as the nylon
cutting head will revolve when starting.
6. Remove any adjusting key, wrench or blade
cover before turning the power tool on. An
accessory left attached to a rotating part of the
power tool may result in personal injury.
Method of operation
1. Only use the tool in good light and visibility.
