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 fig. 12
• 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. 30 degrees to the left (it
is easier if you loosen the loop handle and adjust it) See
fig. 13.
• Do not do this if there is the slightest risk of something
being flung up and injuring people or animals standing
within a radius of 30 metres.
8.3 Adjusting the trimmer line
Adjust the trimmer line like this:
1. Run the engine at full speed whilst carrying out points 2-4.
2. Bang the trimmer head on the ground and lift it up again. See fig. 14.
3. 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 fig. 15.
