4.4 Actuator Maintenance

The actuator is not a regularly serviced item. It is recommended, that the
actuator be disassembled annually. The actuator should be thoroughly
cleaned and all the internal parts inspected for wear.
If the actuator does not appear to be functioning properly, first check the
actuator for air leaks. There should never be air leaking from the bottom
area of the actuator. With the jet on there should be no air leaking from
the exhaust vent. Air leaks indicate that o-rings need to be replaced.
Over time, abrasives can accumulate inside the housing. The o-rings, will
show wear and the springs may lose some of their force. Replace all worn
parts: springs, exhaust vent, piston seal and o-rings.

Actuator Housing Disassembly

1. Remove the air fitting from the top of the
actuator.
2. Remove the Retainer cap from the bottom of the
actuator.
3. Place the actuator in a large vise and tighten the
vise just enough to apply slight compression to
the actuator springs.
4. Use a locking type snap ring pliers to close
(compress) the retaining ring that secures the
Actuator Cap into the Housing.
5. Carefully open the vise while verifying that the
Cap is coming free from the Housing.
NOTE: The actuator contains high force springs
and should be serviced with caution!
