Adjusting the Bowden cables

The Bowden cables of your strimmer are factory-adjusted.
If the position of the "bike grip" handle is changed signifi-
cantly, this can cause the Bowden cable to stretch, result-
ing in malfunctioning 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 (Fig. 10-1).
Correct functioning of the throttle is then assured once
again.
Caution!
Risk of injury from rotating cutting head!
„ Only adjust Bowden cables with the engine switched
off.
„ Only check the function with the strimmer lying down.
