7.7.3 Grab spherical plain bearing (op-
tional)
The facility for lubricating the spherical plain
bearing is intended for machines that are
usually operated with a grab. If the machine is
being operated without a grab, the lube fitting
should be removed. To prevent the central
lubrication system's monitoring facility from
outputting a fault warning, the lube fitting must
not be sealed.
â–º
Place the lube fitting inside a strong plastic
bag and seal up the bag with an elastic
band by wrapping it around the lube fitting.
â–º
Attach the bag containing the lube fitting
securely to the boom.
â–º
Empty the bag at regular intervals.
