Caution
:
Always wear suitable clothing for performing this type of maintenance.
• To detach the first belt drive, the belt drive of the blades needs to be detached first.
• To reach the belt, the belt case needs to be removed (see § “15.1 Removing the protective
covers” on page 71)
• Remove the M6 lock nuts (10 mm spanner) and rotate the control guide counter-clockwise a few
times. Use a spanner (size 9) if necessary. This will reduce the belt tension to a minimum.
• The belts will now be loose, and can be removed easily.
• Next, loosen belt 1 (engine crankshaft - angular transmission) by loosening the central nut and
sliding the bolt up as far as possible. The belt will now be loose, and can be removed easily.
•• Before positioning the belts, check whether they are of the same type and length.
• Now re-apply the proper amount of belt tension (see §”11.4.3
Belt tension check
and adjustment” on page 59)
• After calibrating and testing the belt tension, place the protective covers back on.
11.4.5 Replacing the belt tensioning roller
The machine has 1 belt drive that is provided with a decoupling mechanism via a tensioning roller.
After many hours of operation, the tensioning roller may show signs of wear and tear on the
bearing and tread. This may contribute to increased wear and tear on the belts and cause the
machine to break down. To prevent this, the tensioning roller will need to be inspected regularly
and possibly replaced as a precaution.
