4) Very lightly lubricate the lead screw with white lithium grease.
Caution: Do not over-lubricate the lead screw as this could bind the nut and lead screw.

6) Retract and extend the actuator 20 times to distribute grease along the lead screw.
7) Reinstall the actuator and make sure the actuator shuts off before it reaches a mechanical
stop.
Actuators with limit switches (MX) - LUBRICATION:
1) Press the MANUAL button, then press the OUT button to drive the actuator to its Out limit.
2) Remove the actuator from the positive displacement guide (PDG).
3) Gain access to the lead screw through the top of the actuator next to the cam follower and
spacer. Very lightly lubricate the lead screw with white lithium grease.
Caution: Do not over-lubricate the lead screw as this could bind the nut and lead screw.
4) Reassemble the actuator in the reverse order as disassembly.
5) Retract and extend the actuator 20 times to distribute grease along the lead screw.
6) Reinstall the actuator into the PDG and make sure the actuator shuts off before it reaches a
mechanical stop.
