11.5 Maintaining the mowing
blade
Removing the mowing blade:
For removal, use a wooden block (1)
(approx. 60 x 60 mm) to counterhold the
mowing blade (2).
● Loosen and unscrew the blade
fastening screw (3). Remove the blade
fastening screw (3), washer (4) and
mowing blade (2).
Sharpening the mowing blade:
● Cool the mowing blade when
sharpening, e.g. with water. The blade
must not be allowed to display blue
colouring, as this would reduce its
cutting quality.
● Sharpen blades evenly to prevent
vibration due to imbalance.
● The cutting angle of 30° must be
observed.
● Observe the wear limits when
sharpening.
Installing the mowing blade:
For installation, use a wooden block (1) to
counterhold the mowing blade (2).
● Secure the blade fastening screw (3)
with Loctite 243.
● Fit the mowing blade (2) with the curved
edges pointing upwards onto the blade
bushing (5).
● Fit the retaining washer (4) and tighten
with the blade fastening screw (3) to
60 - 65 Nm.
11.6 Storage (winter break)
Note the following points when storing the
machine for long periods (winter break):
● Clean all external parts of the machine
with care.
● Thoroughly lubricate/grease all moving
parts.
● Empty the fuel tank and carburettor
(e.g. by running empty).
● Unscrew the spark plug (see engine
instruction manual) and pour approx.
3 cm³ of engine oil into the engine via
the spark plug hole. Turn the engine
several times with the spark plug
removed (pull the recoil starter rope).
● Screw the spark plug back in (see
engine instruction manual).
● Perform an oil change (see engine
instruction manual).
