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.
• Inspect the area under the platform, around and
under the air bellows. Build-up of foreign material
in this area may damage air bellows components,
causing abnormal operation.

machine oil:
(A)— Lip hinge area unless equipped with grease
fittings (apply oil to the top of the entire length
of lip hinge when platform is at the full below-
dock position and lip is folded)
(D)— Platform hinge area (apply oil to top of all
platform hinges when platform is at the full
below-dock position)
(E)— Lip lifter and lift cylinder pin
NOTE: Apply grease to lip hinge grease fittings if
equipped.
