Routine Maintenance Overview Checklist
Maintenance
244 Actuator: Maintenance
The 244 Actuator is designed for extended periods of operation without extensive
maintenance requirements.
A summary of the routine maintenance procedures is 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 and/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 can require more or less
frequent seal changes depending on usage. External oil leakage and/or decreased
performance are indicators of seal wear. Seal replacement is considered a service
procedure; contact you MTS Service Engineer for additional information.
298 HSM: Maintenance
