1.The powered A-frame jack motor is sealed and
maintenancefree.
2.Before each use, inspect jack tubes and replace if
bent or damaged.
3.Ensure all connections are tight and free of corrosion
and that the jack is properly ground with the coupler
(metal to metal contact).
4.If necessary, wash with mild soap and water and rinse
thoroughly. The motor ground screw and mounting bolts
must also be cleaned if a ground continuity problem
occurs.
Fully extend the jack and clean the inner jack tube once
per year. After cleaning, coat the tube with a light
grease or silicone spray lubricant.
