Check for binding
Your trailer legs should be cleaned and checked for debris on a regular basis. Sand and dirt will cause legs to bind.

Extend landing legs as far as possible, clean drop tube and inner ram tube. Coat exposed surface of tubes with silicone spray lubricant.
Coat inside of handle alignment tube with silicone spray lubricant.
Oil shaft bushing in gear box and leg gear heads with SAE 30 oil.
Lubricate gears in gear box and landing leg gear heads with extreme pressure grease.
*Do NOT open motor to lubricate as this voids warranty.
Check for damage to legs
Any damage to the legs such a bending or denting will cause binding.
Check power to system
Check that your batteries and power supplies are at full levels to prevent damage to the motor.
Check wiring connections at battery. Clean terminals with a solution of baking soda and water.
Cover with a thin coat of grease.
Check wiring harness fuse, if blown replace with appropriate fuse.
Do not exceed weight limit of landing gear system
Do not use the landings legs to lift the trailer during tire changes, axle work or trailer servicing (the trailer weight will exceed the capacity of the landing legs).
The landing legs are designed to stabilize a portion of the trailer’s weight.
Support the front end of the trailer with structural stands rated for the GVWR of the trailer.
