Replacing top horizontal cutter belt
Check top cutter drive belt tension after first 20 hours of operation and every 50 hours of
operation thereafter.
1. Remove covers as shown on the figure below (1, 2, 3, 4 and 5).
2. Loosen four mounting bolts (A). Two for each side of the moulder.
3. Tighten the tension bolts (B). The motor will be lifted and the belt will be loosened.
4. Mount the new belt.
5. Loosen the tension bolts to lower the motor and tighten the belt. Do not over-tighten the
belt. Properly tightened belt should be deflected by 6 mm with a force of 1,4 kg.
6. Check motor and top cutter pulleys alignment. Both pulleys should be in line to avoid pre-
mature drive belt wear. Loosen pulley screw on the motor shaft to move pulleys. After pul-
leys alignment, recheck the belt tension.
7. Install all covers.
