Jack
As necessary, grease the jack lead screw using the following procedure:
1. Fully extend the jack and apply grease to the lead screw through the grease port
(hole) in the side of the jack body.
2. Cycle the jack up and down several times to distribute the grease on the screw.
The following three sub-sections pertain to trailers with tilt decks-
Cushion Cylinder
The fluid in the cylinder should be changed if the cylinder has leaked or if the deck
action has become jerky and/or sluggish. Fully collapse the cylinder, and then remove
the filler plug and drain out the old fluid. Add 10W hydraulic fluid until the cylinder is full
and all the air has been expelled.
Deck Latch
If the latch becomes difficult to operate apply some penetrating lubricant to the
moving parts. Should the deck develop a rattle, adjust the hook receiver assembly on
the tilt deck.
Deck Hinge Assembly
The hinge assembly is highly stressed during loading and unloading, and so check
it for cracked welds frequently.
Every six months, or sooner if service dictates, grease the deck hinges. Apply grease
to the fittings (one per side) until fresh grease becomes visible.
