When trimming, a bump guard (1) limits the cutting range of
the mowing line and helps prevent unwanted damage to
vegetation in certain circumstances (see illustration).
Always remove the battery before mounting or adjusting the
bump guard.
Observe all applicable laws, regulations, standards and
ordinances.

16.2 Adjusting the Nylon Line

WARNING
To reduce the risk of personal injury from unintended
activation, always switch off the motor and remove the
battery before manually adding or adjusting the nylon line.
► While pressing the trigger switch, tap the rotating mowing
head on the ground.
Approximately 1.2 in. (30 mm) of fresh nylon line will be
advanced with each tap.
The line limiting blade in the deflector trims the mowing line
to the proper length.
The bump feed mechanism will not advance additional line
if the mowing line is shorter than 0.1 in. (25 mm). To feed
additional line manually:
► Switch off the trimmer and remove the battery.
► Depress and hold the button on the mowing head.
► Pull out the mowing line by hand.
► If the mowing line cannot be pulled out to the required
length, install a new spool of line.
STIHL recommends keeping nylon line or polymer blades in
a water bath for at least 12 to 24 hours before use to
1
increase their useful life.
