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 parking brake
Warning
If the parking brake is incorrectly adjusted,
the device can roll away.
► Make sure that the parking brake is al-
ways functioning properly.
1. Place the device on a surface with a good
grip (e.g. concrete or asphalt).
2. Switch off the engine.
3. Turn the switching lever to idling.
4. Try to pull the device backwards.
If the rear wheels lock up, the parking brake is
set correctly. If the device can be pushed, the
parking brake must be readjusted by an au-
thorised service centre.
Checking the blade
Warning
Wear or damage on the blades and the
fastening elements can result in the blades
or the fastening elements coming off.
► Check the blades and all fastening ele-
ments according to the following instruc-
tions.
Warning
There is a considerable risk of injury due to
improperly mounted and maintained blades.
► Work at blades must be carried out by an
authorised service centre.
Use solid gloves when you check
the blade.
Work on the blade requires specific expertise
because an imbalance inspection is necessary
and torques must be observed.
Blades that are sharpened improperly increase
the workload of the device and can result in vi-
bration cracks or breaks.
Check the blade and all fastening elements for
wear, damage and cracks
– each time before and after you mow.
– in case of noticeable changes or unusual vi-
brations.
Contact an authorised service centre if you de-
tect faults or damage during inspection.
All shown blade parts and their fastening ele-
ments must be changed
– if damage or cracks are detected.
– if unusually strong vibrations occur.
– at least once a year or every 50 operating
hours, no matter if wear does exist or not.
