Service and Maintenance
8.2 Grease Point
With the exception of the rotator hanger bearing, pivot points
on the grapple do not require lubrication. The bearings
are made of a self-lubricating composite material that is
designed for heavy loads.
For the rotator hanger bearing, use an SAE multipurpose, high-
temperature grease with extreme pressure (EP) performance.
Also acceptable is an SAE multipurpose lithium base grease.
Lubricate the rotator hanger bearing every 50 hours of use.
• Use a hand-held grease gun. Wipe grease fitting with a
clean cloth before greasing to avoid injecting dirt and grit.
• Replace and repair broken fittings immediately.
• If fitting does not take grease, remove and clean thoroughly.
Also clean lubricant passageway. Replace fitting if
necessary.
