machine oil (see Figure 29):
( 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.)
( E ) — Lip Cylinder pins.
( F ) — Side Shift Cylinder pins.
• Lubricate the following areas with white lithium
grease (see Figure 29):
( C )( G ) — Hoist cylinder grease fittings and pins.
( D ) — Cam roller bearing grease fittings.
Failure to properly lubricate the dock leveler will
cause abnormal operation of the leveler.
• Inspect the following for damage/abnormal wear:
• Check welds for cracks.
• Coils for cracks and/or bent valves.
• Lower pin and mounting holes.
