MAINTENANCE
Regular maintenance must be performed on a
weekly and quarterly schedule.
Weekly Maintenance
• Operate the dock leveler through the complete
operating cycle to maintain lubrication.
NOTE: To thoroughly inspect the platform hinge
area, put the platform in the full below-dock
position.
• 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 cause abnormal operation.

this area may damage air bag components,
causing abnormal operation.

platform hinges when platform is at the full
below-dock position)
