7.5.2 Grab spherical plain bearing
The facility for lubricating the spherical plain
bearing is intended for machines that are
usually operated with a grab. If the machine is
operated without a grab, the lube fitting for the
spherical plain bearing must be sealed with
the plug supplied in the tool kit.
7.5.3 Filling the grease container on the
uppercarriage
Unscrew the cover (274/1) of the grease con-
tainer and fill with grease. The container holds

grease.
It is also possible to fill the grease container
via the filler nipple (274/2).
h Chapter 7.3 Fuels, lubricants and coolants
If the lubrication system runs completely dry,
you should add a few drops of oil before refilling
it with grease. This will force the air out of the
piston components.
The grease must be free of contamination and
may not change its consistency over time. Lu-
bricating additives, such as molybdenum disul-
fide, must not be mixed in.
Additional lubrication may need to be trig-
gered after filling to achieve complete venting.
