7.7.4 Filling the grease container on the
uppercarriage
Unscrew the cover (181/1) of the grease con-
tainer and fill with grease. The container holds
approx. 4 kg of multi-purpose grease.
It is also possible to fill the grease container
via the filler nipple (181/2) up to the overflow.
h Use the following grease: Chapter

67HFuels, 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.
Grease must be free from impurities and its vis-
cosity should not change over time. Lubricating
additives, such as molybdenum disulfide, must
not be mixed in.
Additional lubrication may need to be trig-
gered after filling to achieve complete venting.

lubrication pulse
7.7.4.1 Triggering an additional lubrica-
tion pulse
An "additional lubrication pulse" for additional
lubrication of the uppercarriage can be trig-
gered in the function menu using the pushbut-
ton function (182/101). The additional lubrica-
tion pulse then runs automatically.
An "additional lubrication pulse" for additional
lubrication of the undercarriage (optional) can
be triggered in the function menu using the
pushbutton function (182/107). The additional
lubrication cycle then runs automatically.
