MAINTENANCE
Weekly Maintenance
• Operate the dock leveler through the complete
operating cycle to maintain lubrication.
• Inspect the platform hinge and the lip hinge areas.
The hinge areas must be kept free of dirt and
debris. Build-up of foreign material in the hinge
areas will increase wear and cause abnormal
operation.
• Inspect warning decals and placards. Replace if
damaged or missing.
• Check bumpers for more than 1” of wear. Replace
worn, loose, damaged or missing bumpers.
