MAINTENANCE AND CARE
Air filter

Never operate the device without an air
filter. Clean the air filter regularly. Exch-
ange the filter if damaged.

filter. Severe engine damage may result.

tainer.
3. Pull the filter out of the tank with a wire hook.
4. Remove the filter with a twisting motion.
5. Exchange the filter.
Adjusting the Bowden cables
see Figure 9
The Bowden cables of your strimmer are fac-
tory-adjusted. If the position of the “bike grip”
handle is significantly changed, this can cause the
Bowden cable to stretch, resulting in malfunction-
ing of the throttle.
If the cutting head does not come to a standstill
after the strimmer has been started and the half
throttle lock has been released, the Bowden cable
must be adjusted by means of the adjusting screw
(1) . Correct functioning of the throttle is then as-
sured once again.
