● Place the machine on level and firm
ground when performing all the
operations described.
8.2 Folding down the handlebar
The handlebar can be folded down
for space-saving transport and
storage of the mower.
Danger of pinching!
The handlebar can fold down
uncontrolled when the quick-
clamping devices are released. For
this reason, always hold the
handlebar with one hand while
releasing the fastening.
● Detach the recoil starter rope. (
● Hold upper handlebar (1), open left and
right quick-clamping devices (C) and
carefully fold the handlebar downwards
to the front.
8.3 Adjusting the front wheel
Three different settings can be
selected at adjusting element (1).
Danger of burns!
When touching the machine at
wheel fork (2), ensure that you
maintain a safe distance from the
engine and from the silencer – parts
of the engine become hot following
prolonged use.

wheel swivels through 360°" position
and ensure that it engages fully.
8.4 Adjusting the cutting height
Risk of injury!
When adjusting the cutting height,
make sure that the housing is
always parallel to the ground – this
also achieves optimal mowing
results.
The machine has two cutting height
adjustments:
1. Rear wheel cutting height
adjustment (
2. Front wheel cutting height
adjustment (
Five different cutting heights can be set.
Level 1 = 25 mm
Level 5 = 80 mm
Cutting levels 2 to 4 are standard,
especially when using the machine as a
mulching mower. (
STIHL recommends setting the required
cutting height at the rear wheel first and
then adjusting the cutting height at the
front wheel. The cutting height is set
correctly when the housing is parallel with
the ground.
