244 Actuator: Maintenance

The series 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

The series 298 Hydraulic Service Manifold requires the filter be changed

periodically.
