Risk of injury!
Operation of the blade brake clutch
must be checked before each use.

never be disabled, e.g. by tying it to
the handlebar.

The mowing blade can only be engaged as
follows with the engine running:
Press one of the two blade stop levers (2)
with one hand and, while keeping it
pressed, pull the blade clutch lever (6)
10
upwards with the other hand and allow it to
engage. ( 11.3)

When the handlebar is released, the
mowing blade is disengaged and braked to
a standstill within a maximum of three
seconds, while the engine continues to
run. ( 11.4)
10. Notes on working with
the machine
A perfect, thick lawn is achieved by
– Mowing at low driving speeds.
– Mowing regularly and keeping the grass
short.
– Not cutting the lawn too short in hot, dry
conditions as it will be burnt by the sun
and become unsightly.
– Using a sharp mowing blade – mowing
blade should therefore be sharpened
regularly (specialist dealer).
– Changing the cutting direction regularly.
