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: Make sure the limit switch is clear of debris.
• 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.
Quarterly Maintenance
• Lubricate the following areas with light weight
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 in the
stored position and lip is folded)
(B)— Platform hinge area (apply oil to top of all
platform hinges when platform is in the stored
position)
(C)— Apply a light oil to the Storage prop pins.
(D)— Grease the hoist cylinder grease fitting
(E)— Apply a light oil to the Lip Cylinder pins.
NOTE: Apply grease to lip hinge grease fittings if
equipped.
M — Reservoir
N — 2 in. (51 mm) (From Top of
Reservoir)
P — Breather Cap
Q — Fluid Level
• Check reservoir fluid level (Q):
1. The leveler must be in the stored position with
the lip lowered.
2. Turn OFF all electrical power to the leveler.
3. Remove breather cap (P).
4. Measure fluid level. The fluid level should be
approximately 2 in. (51 mm) (N) from top of
reservoir (M) with platform at the below-dock
position.
5. Add hydraulic fluid if necessary. Use only
recommended fluid.
6. Install breather cap
7. Turn ON electrical power to the leveler.
8. Return the lip to the raised position.
IMPORTANT
Failure to properly lubricate the dock leveler will
cause abnormal operation of the leveler.
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.
