• After reversing or replacing the blades, always check the torque of the blade bolts after the fi rst
5 working hours and adjust, if required.
Caution:
• Incorrectly or poorly installed blades may lead to the machine breaking down
or being damaged. This will also put operators and bystanders in danger.
• Not retightening the blades after the fi rst 5 working hours after reversing or
changing the blades may lead to the machine breaking down or being damaged.
• The damage and consequential damage that may arise from poor maintenance
of the blades will invalidate the warranty.
11.5.4 Adjusting the drive belt tension
The machine is equipped with a long drive belt. The belt will show some sagging (stretching)
after a certain number of working hours, which means that it will lose tension. Insuffi cient ten-
sion on the belt will make the belt slip when the load is heavy, which increases the wear on the
belt and the service life will
be reduced. A belt that is
insuffi cient tensioned, will fl ap
around and, therefore, there
is a risk that the belt will slip
out of the pulley. Regularly
check the belt for correct ten-
sion (every 50 working hours).
Caution:
Tension the new belt for the fi rst time after a break-in period
(run in period) of 10 working hours.
• Always switch off the engine and remove the key from the ignition as should be done for every
maintenance task.
• Fold the right safety guards up for adjusting the tension. (See § AP.A-P1)
