Checking the drive
1. Put the device on a non-slip surface (e.g.
concrete or asphalt).
2. Switch off the engine.
3. Actuate the drive.
4. Try to pull the device backwards.
If the rear wheels lock, the drive is correctly ad-
justed. If you can pull the device, the drive
must be re-adjusted.
Re-adjusting the drive
Turn the adjusting screw (
1
) at the drive so that
the wheels lock, while the drive is actuated,
when the device is pulled. If there is no im-
provement after the adjustment, have the
device checked by an authorised service
centre.
Checking the blade
Danger!
Improperly mounted and maintained
blades pose a severe injury hazard.
Work at the blade shall only be per-
formed by an authorised service
centre.
Use solid gloves when you check
the blade.
Work at the blade requires specific expertise
because an unbalance inspection is necessary
and the torques must be observed.
Check the blade and all fastening elements for
wear, damage and cracks
– each time before and after you mow.
– if there are noticeable changes.
All shown blade parts and their fastening ele-
ments must be changed
– if damage or cracks are detected.
– at least once a year or every 50 operating
hours, no matter if wear does exist or not.
The material weakens, can suffer cracks,
endangering people and material assets.
Vibrations are an indication that
– the blade is worn excessively or on one side
or
– damage to the engine or cutter deck fasten-
ing.
Blades that are sharpened improperly increase
the workload of the devices and can result in
vibration cracks or breaks.
Ejected broken pieces can cause severe injur-
ies.
