MAINTENANCE
Return the bolts to their original position as described in (b) above.
NOTE: If machine sits outside longer than 30 days
and is exposed to rain and humid air, the Torque
Limiter should be removed from machine and
stored in a dry area. Torque Limiter facings will soak
up moisture and cause the metal plates to rust
badly. When this occurs, the break-away torque
increases greatly and damage to gearbox, driveline,
or tractor PTO can occur.
