5. Assembly
The shafts (5a), (5b), the loop handle (4) and the trimmer safety guard must be assembled
before use.
Joining the shafts (5a) and (5b)
1. Insert the lower shaft (5b) into the upper shaft (5a) until the ball-lock secures it in place.
. Tighten the shaft locking knob.
Assembly of secondary handle (4)
1. Loosen the screws and washers on the secondary handle.
. Take hold of the secondary handle (4), (together with
the enclosed side handle) on the upper shaft (5a) and
attach with washers and screws. The side handle can
be assembled either on the left or right side to adapt the
trimmer to right or left-handed users.
. Adjust the position of the secondary handle (160 – 00 mm
in front of the throttle lever) and screw together.
Assembly of the trimmer guard (3)
Warning! The trimmer guard must be assembled correctly to protect the operator and to
limit the length of the trimmer line. There is a cutter on the guard that cuts the line to the
right length.
1. The trimmer head should be disassembled
before assembling the trimmer guard ().
. Hold the trimmer head and use your hand
or the enclosed key to loosen the trimmer
head nut. See gure 4.
. Remove the trimmer head from the spindle.
4. Slide the trimmer guard over the shaft and
align the holes in the guard with holes in
the bracket. See gure 5.
5. Pass the bolt through the trimmer
guard from the side with the hexagonal
countersink and assemble the washer and
nut. See gure 6.
6. Reassemble the trimmer head on the
spindle. See gure 7.

ENGLISH
6. Fuel and lubrication
Warning! Petrol is highly ammable. Avoid smoking close to where fuel is handled, do not
cause any sparks embers or naked ames either. Switch off the grass trimmer and let it
cool before refuelling it. Refuel outdoors and always move at least 3 metres away from the
refuelling site before starting the trimmer.
Mix petrol (unleaded 95 octane without added ethanol) with a good quality -stroke oil intended
for air-cooled -stroke engines. Recommended mixture: Petrol/oil 40:1 (.5 %).
• The engine is designed to be used with unleaded fuel.
• Use at least 87 octane fuel.
• Use unleaded fuel to protect the environment and your health.
• Bad quality fuel or oil can damage seals, fuel lines or the fuel tank.
6.1 Mixing the fuel
Note! Be precise with the mixture.
1. Measure out the petrol and oil precisely before mixing.
. Pour a small amount of the petrol into a clean fuel can.
. Pour in all of the oil and shake the fuel can.
4. Pour in the rest of the petrol and shake the fuel can for at least a minute. Certain oils do not
mix well; therefore it is important that the fuel can be agitated to mix the oil and petrol. The
engine will last longer if the fuel is well mixed, if the fuel is not mixed properly the mixture
will be too lean and the engine may be damaged.
5. Label the fuel can clearly, to avoid the risk of misidentication.
6. Fuel containing oil is only intended for -stroke engines, pure petrol is for 4-stroke engines,
it is therefore very important to label the fuel cans clearly.
Note! Do not mix too much fuel; it should be used within 90 days.
Warning!
Only use fuel containing oil for 2-stroke engines, using pure petrol without the addition
of oil will soon cause engine damage which is not covered by the guarantee.
6.2 Refuelling the grass trimmer
1. Unscrew and remove the fuel cap.
. Fill with fuel until the tank is roughly 80% full.
. Replace and tighten the fuel cap then wipe up any spilt fuel on or around the grass trimmer.
Warning!
1. Refuel outdoors and on the ground.
. Always move at least metres away from the refuelling site before starting the trimmer.
. Switch off the grass trimmer and let it cool before refuelling it. Only refuel when you are
sure that the fuel can contains -stroke fuel!

7. Starting the engine
Note! Pull the starter handle straight out, if you pull at an angle the starter cord will rub on the
sleeve and soon wear out. Keep hold of the starting handle after pulling it and allow it to return
slowly. Never let go of the starting handle straight after pulling it, it could get tangled or break
something on the trimmer.
Note! See section “Troubleshooting” if the trimmer doesn’t start after several attempts.
7.1 Starting the engine from cold
Cut the trimmer line to a length of 1 cm before starting to
reduce the load while the trimmer warms up.
1. Place the grass trimmer on a level surface.
. The spring switch (6) is always in the position ‘1’ and
does not need to be touched during ignition. See gure
9.
. Turn the choke (9) down to the “COLD START” position.
See gure 10.
4. Push in the primer bulb (10) 6 times. (the primer bulb is
on the upper side of the carburettor.) See gure 11.
5. Take a steady grip of the back handle.
6. Pull on the start line until a resistance is felt (circa 100
mm). See gure 1, then jerk the start line quickly until
the motor starts. This process can be repeated up to six
times in quick succession.
7. When the motor has started, let it run idle for circa 10
seconds and then push the safety catch (1) and the
throttle lever (8) so that the choke lever automatically
returns to the ‘Drive’ position.
8. Before loading, let the motor run on ‘no-load’ for a while
until it responds to throttle increase.

7.2 Starting a warm motor
1. Place the grass trimmer on a at surface.
. The spring switch (6) is always in the position ‘1’ and
does not need to be touched during ignition.
See gure 9.
. Turn the choke lever (9) down to the ‘COLD START’
position and then turn up the choke lever to its original
position. See gure 1.
4. Take a steady grip of the back handle.
5. Pull on the start line until a resistance is felt (circa 100
mm). See gure 11, then jerk the start line quickly until
the motor starts. This process can be repeated up to six
times in quick succession.
6. If the motor does not start repeat all of the steps in ‘Start
of cold motor’.
7.3 Switching the engine off
Release the throttle and let the engine idle, turn the ignition
switch (7) to “STOP”. See gure 14.
Helpful suggestions
Warning! Remove all objects such as cans, bottles and stones from the ground before
starting to use the grass trimmer, otherwise they can be thrown about by the trimmer
line and cause injury or damage the trimmer.
Switch off the grass trimmer at once and check it for damage if you notice that something is
ejected or if the grass trimmer starts vibrating. Do not operate the grass trimmer if it has been
damaged.
Note! Allow the engine to reach full speed before starting to cut the grass, never try to cut
grass at low speed.
Warning! Never raise the trimmer head above knee-height when it is spinning.
Warning! Never use metal or plastic coated metal trimmer line, this could cause serious
accidents.

8. Use
• Hold the grass trimmer in both hands.
• Depress the throttle and let the engine speed up.
• Hold the trimmer head parallel to the ground and swing
the grass trimmer from side to side whilst walking slowly
forwards, do not move forward so much if the going gets
heavy. See g. 15.
• Do not move the trimmer head towards you, always work
away from yourself.
8.1 Trimming round trees and bushes
Lean the trimmer head forward slightly and start trimming from
left to right whilst slowly walking around the tree. Be careful, so
the trimmer line doesn’t cut the bark of the tree or the plants
you want to keep! If you trim grass close to fences, foundations,
rocks etc, the trimmer line will soon wear out.
8.2 Preparing the ground (removing all
vegetation)
• Angle the trimmer head approx. 0 degrees to the left (it is
easier if you loosen the loop handle and adjust it).
See g. 16.
• Do not do this if there is the slightest risk of something being
ung up and injuring people or animals standing within a
radius of 0 metres.
8.3 Adjusting the trimmer line
Adjust the trimmer line like this:
1. Run the engine at full speed whilst carrying out points -4.
. Tap the trimmer head on the ground and lift it up again. See g. 17.
. The line will be fed out automatically.
4. The line will be cut to the correct length by the cutter under the trimmer guard.
5. Switch off the engine and using something like a screwdriver, clean off any grass and
debris from around the guard and trimmer head, otherwise it could impair the cooling of the
drive shaft. See g. 18.
