11.2.1. Special maintenance
a. Special maintenance of the blades
After inserting the blades into the shaft, they will need a short running-in period. This could
lead to a loosening of the bolts. The blades could even come loose over time and become
wedged between the blade discs if they are not checked regularly. This could cause irrepa-
rable damage to the blade shaft. This must be prevented by scheduling extra maintenance
after the brief running-in period.
When:
• Within the first 5 operating hours after starting up the new machine.
• Within the first 5 hours after turning the blades.
• Within the first 5 hours after replacing the blades.
What:
• Check all blade bolts for correct torque and adjust if necessary.
(see Section 17.2, page 83)
Warning: Failure to perform this special maintenance will compromise the safe-
ty of operators and bystanders, and can cause serious damage to the machine.
b. Special maintenance of the drive belt
The belt that transfers power from the engine to the blade shaft is long. During the running-
in period, the belt will stretch naturally. This stretching will reduce the tension of the belt.
Using the machine when the belt tension is too low will cause the belt to slip, twist or come
off the pulleys. These three possibilities will 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:
• Ensure correct belt tension. (see Section 11.5.4, page 69)
c. Special maintenance related to replacing the engine oil
All wear-and-tear particles and manufacturing dirt that is created or is still present in the
engine will be captured by the oil filter. Fine particles that have not been captured by the oil
filter will be rinsed away by this special maintenance.
When:
• Within the first 5 operating hours after starting up the new machine.
What:
• Change the engine oil. (see Section 11.4.2, page 57)
