6. MAINTENANCE
The Hawk actuator is designed to provide robust and precise operation while keeping maintenance to a
minimum. However, adequate preventative maintenance procedures are paramount to extending the life
of any mechanical device, including the Hawk, and are highly recommended.
6-1 Quarterly Inspection/Maintenance

correctable mechanical issues. Quarterly inspection checks should include, but not be limited to, the
following:

 Are mounting bolts and screws fastened correctly
 Is there hydraulic fluid pooling on or below the actuator
 Are cable connections secure at both the HPS and Control Enclosure
 Are there cuts or excess wear in cables
 Is there moisture or dirt in the HPS or Control Enclosure
 Is the HMI responding accurately to user input
 Is the actuator hunting or unable to hold a position
 Is the actuator responding accurately to control signals
 Is the position feedback signal accurate and stable
6-2 Five Year Inspection/Maintenance

performed at five (5) year intervals:
 Quarterly visual inspection
 Install soft goods repair kit (includes cylinder, manifold, and HPS soft goods)
