• Only allow service personnel trained in safety and
maintenance on this winch to perform maintenance.
• After performing any maintenance on the winch, test
winch to 125% of its rated capacity before returning to
service. Testing to more than 125% of rated capacity
may be required to comply with standards outside the

Maintenance Intervals
The Maintenance Interval chart is based on intermittent
operation of the winch eight hours each day, five days per
week. If winch operation exceeds eight hours per day, or
use is under HEAVY or SEVERE conditions, more
frequent maintenance should be performed. Refer to
‘Periodic Inspection’ in the “INSPECTION” section for
interval guidance.
