MAINTENANCE
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. Look for cracks in the welds
or damage. Build-up of foreign material in this area
may damage air bellows components, causing
abnormal operation.
• Inspect warning decals and placards. Replace if
damaged or missing.
• Check Kill Frost level and refill if required.
• Drain water from the regulator and the compressor.
• Verify line pressure is at 95 PSI.
Quarterly Maintenance
• Complete Weekly Maintenance.
• Inspect the following for damage/abnormal wear:
• Check welds for cracks.
• Lip hinge pins and rear hinge pins.
• Check full range toe guards (if equipped) for
free movement.
• Inspect air lines.
• Control box and conduit for damage.
• Bumpers for more than 1” of wear. Replace
worn, loose, damaged or missing bumpers.
• Side and rear weather seals (if equipped).
• Lubricate the following areas with light weight
machine oil (see Figure 23):
(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).
(C)— Lip link pivots.
(B)— Lip maintenance prop pivot.
(G)—Safety leg linkage pivots.
• Lubricate the following areas with white lithium
grease:
(E)— Lip assist pin.
Note: Apply grease to lip hinge grease fittings if
equipped.
Failure to properly lubricate the dock leveler will
cause abnormal operation of the leveler.
