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 lug and the lip lug 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.
Quarterly Maintenance
• Lubricate the following areas with light weight
machine oil:
(B)(D)- Platform lug area (apply oil to top of all
platform hinges when platform is at the full
below-dock position)
• Lubricate the following areas with white lithium
grease:
(A)— Lip lug area (apply oil to each of lip and
platform lugs when platform is at the full
below-dock position and lip is folded)
(C)(E) - Both Hoist and Lip cylinder trunnions
• Check reservoir fluid level (Q):
1. Put the dock leveler platform at the full
above-dock position, engage prop.
2. Turn OFF all electrical power to the leveler.
3. Measure fluid level. The fluid level should be
approximately 3 in. (76.5 mm) (N) from top of
reservoir (M) with platform raised on the
maintenance prop.
4. Add hydraulic fluid if necessary. Use only
recommended fluid.
5. Turn ON electrical power to the leveler.
6. Return the platform to the cross-traffic position.
Before performing any maintenance under the
dock leveler, lock the electrical power source in
OFF position and lock the maintenance prop in the
service position using an approved locking device.
(See Service Dock Leveler Safely in this section.)
Failure to follow these instructions may result in
serious personal injury or death.

IMPORTANT
A low fluid level or the use of hydraulic fluids not
equivalent to the fluid types recommended, will
cause abnormal operation of the leveler and WILL
void warranty.
