cles (objects like wire, stones, threads or
glass) that might be flung up into the air.
 Press the release button.
 Push the power switch, device starts.

 Guide the brush cutter over the uncut

Setting the string length

When mowing, the string of the string trim-
mer will be subject to wear and tear - it will
fray, be torn off and therefore become
shorter.
A string that is too short will result in unsat-
isfactory mowing results.
NOTICE
The string length can be extended during
operation.
 To extend the string automatically, tap
the base of the cutting head briefly.
NOTICE
If the string is no longer extended automat-
ically, it will have to be replaced.
