Unfortunately old man winter is slowly creeping up on us and its time to prepare our actuators for it. I have my dishes at their extreme western limit with the actuator arm extended as much as possible. Many use different types of lubricant but I choose to use white lithium grease lubricant for my motors. Just spray the whole arm of the actuator and make sure you check all screws to make sure they are tight- tough to do at -20 and with snow on the ground. Once applied, I send my dishes to their eastern limit to make sure that the lubricant is well spread over the arm. Process takes like 5 minutes but keeps your motor in great shape to withstand whatever mother nature can throw at you.
