(Ö 8.5)
● Loosen handlebar screw
fastening/quick clamping device (2)
and fold down upper handlebar (3) to

place in the service position as shown.
● First, remove accumulated clipping
deposits in the housing using a stick.
● Clean the entire machine, especially
the mowing blade and engine, using
little water, with a brush or with a cloth.
Never spray water (high-pressure
cleaner) onto engine components,
seals and bearing points, never use
aggressive cleaning agents.
12.2 Checking blade wear
Maintenance interval:
Before each use.
Checking procedure
● Place the machine in the service
position. (Ö 12.1)
● Clean mowing blade (1).
● Use slide calliper (2) to measure blade
thickness (A) at several points.
● Measure permissible grinding (B).
Place ruler (3) against the front blade
edge as shown for this purpose.
Wear limits
Blade thickness (A):
> 2,5 mm
Permissible grinding (B):
< 5 mm
The blade must be replaced if the
measured values are achieved at one or
more points or are outside the permissible
limits.
12. Maintenance
Risk of injury!
Carefully read the section "For your
safety" (Ö 4.), particularly the
subsection "Maintenance and
repairs" (Ö 4.7), and follow all
safety instructions exactly before
performing any maintenance or
cleaning operations on the
machine.
Allow the machine to
cool and detach the
spark plug socket before
performing any
maintenance or cleaning
operations.
Risk of injury!
Stop the engine, allow the machine
to cool and detach the spark plug
socket.

Clean the lawn mower in the
described position only. This
ensures that no fuel or engine oil
can escape.
Risk of injury!
Blades are subjected to differing
degrees of wear depending on the
location and duration of use. If you
use the machine on sandy ground
or use it frequently under dry
conditions, the blade will be
subjected to greater loads and will
wear more quickly than the
average.
A worn blade may break off and
cause serious injuries. The
instructions for blade maintenance
must therefore always be
observed.
