4.05 - Belt Replacement
If the belts have been stretched or damaged to the point where the proper tension can
not be obtained they must be changed. All four belts must be changed at the same time.
To replace the belts do the following:
1. With the shredder stopped supported by stands, remove the belt shield. Clean the
belts, pulleys and shield of grass, dust and dirt.
2. Loosen the locking nut and unscrew the adjustment bolt (see fig. 9) .
3. Remove the old belts one at a time and replace them with the new belts using a
screwdriver if needed.
4. Tighten the belts with the adjustment bolt then secure it with the locking nut.
5. Ensure that the belts are at the proper tension
(see fig. 9) .
6. Replace the belt shield.
4.06 - Pulley Alignment
For proper operation and extended belt life the upper and lower pulley of the shredder
need to always work aligned to one another. After replacing the belts, place a straight
edge over two sides of each pulley to check their alignment
(see fig. 10) . If the pulleys
are aligned the straight edge should lay evenly across the surface of both pulleys
