11.5 Maintenance schedule
11.5.1 Normal maintenance schedule
Daily (after each use) : Daily maintenance § 11.5.3
Every 50 hours : Maintenance after 50 hours § 11.5.4
Every 100 hours (six-monthly) : Maintenance after 100 hours § 11.5.5
Every 200 hours (or annuall y) : Maintenance after 200 hours § 11.5.6
11.5.2 Special maintenance
A. Special maintenance of the blades
After inserting the blades into the rotor, the blades will bed-in after a brief period. This can cause
the tension on the bolts to decrease, with the risk that the blades m ay become dislodged between the
blade plates. This can cause irrevocable fatigue failure of the blade shaft. This must be prevented by
scheduling extra maintenance after the brief bedding-in period.
When: Within the first five operating hours after starting up the new machine
Within the first 5 hours after rotating the blades
Within the first 5 hours after changing the blades
What: Check all blade bolts for correct torque loading and retighten if considered necessary.
(torque loading : 40 Nm )
Warning :
Failure to perform this special maintenance will compromise the safety of the
operators and bystanders and can cause serious damage to the machine.
B. Special maintenance of the drive belt
The belt that transfers the power from the engine to the blade shaft is long. During the bedding- in
period, the belt will stretch naturally to a certain extent. This stretching will reduce the belt
tension. Using the machine when the belt tension is too low will cause the belt to sli p, twist or wear
down. These three possibiliti es have a detrimental effect on a new belt.
When: Within the first 10 operating hours after starting up the new machine
Within the first 10 hours after changing a belt
What: Check the belt tension (see Chapter 11.4. 4)
