JACK MAINTENANCE
The following procedures should be performed at least annually.
SIDE-WIND MODELS
•
The internal gearing and bushings of the jack must be kept lubricated. Apply a small amount of automotive
grease to the internal gearing by removing the jack cover, or if equipped, use a needle nose applicator or
standard grease gun on the lubrication point found on the side of the jack near the crank. Rotate the jack
handle to distribute the grease evenly.
•
A lightweight oil must be applied to the handle unit at both sides of the tube.
•
If equipped, the axle bolt and nut assembly of the caster wheel must also be lubricated with the same light
weight oil.
TOP-WIND MODELS
•
Apply a lightweight oil to the screw stem.
