GREASING THE HI-LEAD SCREW:
1. The Hi-Lead ® Screw which drives the lift platform up and down must be lubricated at minimum once per
year or more frequently if the VPL is used in extremely hot or cold locations. Use Chevron Ulti-plex
®
Synthetic Grease EP, NLGI Grade 1.5, or equivalent. (FIG. 14.1)
Failure to use the correct grease and or keep the Hi-Lead ® Screw properly lubricated can cause
equipment failure and will void the warranty.
2. Remove the power head plastic cover and either the front or rear cover panel of the lift tower. (FIG. 4.1)
The Hi-Lead ® Screw is more easily accessed by removing the rear cover panel.
3. Use a brush or similar tool to work the grease into the screw threads and grease the entire Hi-Lead ®
Screw (even the sections above and below where the carriage travels).
4. Move the lift platform up or down approximately 1 foot and grease the previously inaccessible area
where the carriage was located.
5. Cycle the VPL up and down a couple times to help spread the grease and apply additional grease to
any areas which appear ungreased.
6. Reinstall the protective cover panels and power head plastic cover and tighten all screws securely.
