Maintenance Recommendations

The Series 244 Actuator is designed for extended periods of operation without extensive maintenance
requirements.

Warning:

Changing the servovalve/actuator configuration will impact the actuator’s maximum attached
mass for cushion design limit.

Operating an actuator outside of its design limit can result in injury to personnel or damage to
the equipment.

Do not alter the given servovalve/actuator configuration.

The routine maintenance procedures are listed below:

Weekly

Clean exposed areas of the actuator piston rod with a clean, dry, lint-free rag. If the actuator is continually
exposed to a dirty operating environment, clean the piston rod on a daily basis.

Monthly

Inspect actuator piston rod and seals for excessive wear or leakage. Small scratches in the axial direction of
the piston rod or polishing of the rod surface is considered normal operating wear.

Yearly

Change actuator seals if necessary. Actuator assemblies may require more or less frequent seal changes
depending on usage. External oil leakage or decreased performance are indicators of seal wear.
