GREASING THE BALL-SCREW
It is important to grease the ball-screw mechanism annually to prevent signicant corrosion. The ball-
screw must be greased immediately prior to winter storage. To grease the ball-screw, lower the lift bed
completely. With the bed lowered, the grease tting should be visible. It may be necessary to raise the
lift slightly to align the grease tting in the hole. Use a high quality extreme pressure lithium grease and
a grease gun tted with a ush style grease tip as shown in Fig. 73 below. A lithium grease that meets
these specications is AeroShell Gadus S2 V220 2. Apply at least six pumps of grease per greasing.
Cycle lift completely up and back down to apply a coat of grease to the ball-screw.
Flush Style Fitting
This tting allows mess-free greasing access to
the ball-screw mechanism.

Flush-Style Grease Gun Tip
Use a ush style coupler grease tip like the
one included in your tool kit for your grease
gun. Similar adapters are available through
NAPA automotive parts stores.

GREASING THE THRUST BEARING
It is important to grease the thrust bearing mechanism annually to prevent signicant corrosion. See maintenance
