Maintenance
Periodic lubrication of Thrust Rod
After 20,000 operating cycles, re-lubricate the actuator thrust rod.
Make sure it is safe to depressurize the system. Move the setup knob to the Operate Pulse mode and
pressing the Jog Dn button, retract the thrust rod to its most retracted position (Zero output pressure
from the pressure regulator). To expose the thrust rod remove the four bolts that attaches the pressure
regulator to the actuator housing. Remove the pressure regulator and Thrust Rod Cap exposing the
Thrust Rod. With the setup knob to the Operate Pulse mode and pressing the Jog Up button, extend the
thrust rod to its most extended opposition. Apply Dow Corning G-n lubricant to the exposed thrust rod
thread. Using the Jog Dn button, retract the thrust rod to its most retracted position. Re-install the
thrust rod cap and pressure regulator.
Caution
•
Shutting off Motor Set Pressure Regulator and disconnecting associated equipment can cause
dangerous system conditions to exist. Ensure the System is properly prepared for maintenance to
be performed on the unit before taking it out of service.
