If a taper lock adapter assembly is found to be in need of tightening after checking the bearing locknut by performing
steps 1 and 2 of the 40 hour maintenance schedule above, then the following action must be taken:
1. Bend the locking tang of each bearing lock washer out to free the bearing locknut.
2. Loosen the bearing locknut with the spanner wrench included with this product.
3. Retighten the bearing locknut until finger tight.
4. Use the spanner wrench to tighten the locknuts an additional 1-1/4 turns and, if necessary, continue tightening until
the first time when one tang of the bearing lock washer is aligned with a notch on the locknut.
5. Bend that tang of the bearing lock washer back into the notch on the locknut.
6. Replace and properly secure the appropriate drive shield(s).
CHAIN TENSION ADJUSTMENT
If the chain is found to be in need of tightening after checking the chain tension by performing steps 1 and 3 of the 40
hour maintenance schedule on the maintenance page, then the following action must be taken:
1. Shut off your
power unit’s engine, remove the starter key, wait for all moving parts to come to a stop, and relieve all
pressure in the hydraulic lines.
2. Remove cover over rotor drive chain.
3. Check chain to see if adjustment is needed: Remove (1) link if possible (It may be necessary to add back in 1/2 link).
There should be at least 1/4” of movement in the chain. The height of the motor mount weldment may also be
adjusted to change chain tension.
4. Replace and properly secure the appropriate drive shield(s).
Brush Drive Side
1. Shut off your power unit’s engine, remove the starter key, wait for all moving parts to come to a stop, and relieve all
pressure in the hydraulic lines.

4. Adjust the brush leaving a 1/4” of movement in the chain and a maximum of 5/16” between the brush and the drum. If
the is more than 5/16” between the brush and the drum, then remove a 1/2 link from the chain. Be sure to adjust both
