LUBRICATION: Most electric step manufacturers recommend not using WD-40 or a silicone-based lubricant. A good quality moisture and heat resistant penetrating grease should be used every 30 days after a through cleaning.
Clean salt, mud and road grime from all moving parts. Spray the step moving parts with fresh water and let dry. Lubricate the square shaft bearings, bushing-in-bushings, and any bearings under a removable cover.
Electrical connections should be protected with a dab of dielectric grease. Replace corroded connections with an automotive type connector – preferably with heat shrink protection.
Cam stops may be need adjusted if your steps feel loose. See your owner’s manual for the proper adjustment. With the steps fully extended, the step should not move inward.
ELECTRICAL: Note: Disconnecting the power wire may produce a spark, this is normal. Control unit is not shutting off– Disconnect the power to the step and request technical help. Your step motor will burn up if left on.
Erratic Operation: Check the vehicle battery for low voltage (12.6 no load amps); a bad ground or convertor not capable of providing 30 amps of power. If you are capable electrical tester = test the door switch, battery disconnect switch, override switch and related fuses. Refer to your owner’s manual for locations. Each of these items is tested according to your Owners Manual.
