HI-LEAD® SCREW LUBRICATION
21.1.
OVERVIEW
21.1.1.
The Hi-Lead® Screw
(“screw”)
drives the lift platform up and down and must be lubricated at
minimum once per year or more frequently if the VPL is used in extremely hot or cold
locations (FIG. 21.1).
21.1.1.1.
Use Chevron Ulti-Plex® Synthetic Grease EP, NLGI Grade 1.5, or equivalent.
Failure to use the correct grease and or keep the screw properly lubricated can cause
equipment failure.
21.1.2.
Remove the power head cover
(“hood”), per
instructions in SECTION 5.
21.1.3.
Remove either the front or rear cover panel (FIG. 21.1).
21.1.3.1.
The screw is more easily accessed by removing the rear cover panel (removing both
rear cover panels on lifts taller than
72”
is required).
21.1.4.
Use a brush or similar tool to work the grease into the screw threads, even the sections above
and below where the carriage travels.
21.1.5.
Move the lift platform up or down approximately 1-foot and grease the previously inaccessible
screw area where the carriage was located.
21.1.6.
Cycle the VPL up and down a couple of times to help spread the grease. Add grease to any
areas which appear unlubricated.
21.1.7.
Reinstall cover panel(s) and hood.
21.1.8.
Tighten all fasteners securely.
