7.5.3.1 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 (275/66), and for the undercar-
riage (optional) using (275/73). The additional
lubrication pulse then runs automatically.
7.5.3.2 Lubrication when lubricating
pump is faulty
If the lubricating pump is defective,
it may cause serious bearing
damage. The lubricating pump
must therefore be repaired imme-
diately.
If the loading machine starts running again on
its own accord for a short period of time, the
lubrication system behind the lubricating
pump should be supplied with grease manual-
ly.
Lubrication interval: every 4 operating hours
►
Attach filler pump to grease nipple (276/1).
►
Pump in lubrication grease until fresh lubri-
cation grease escapes from the boom
bushings and dipperstick bearing, creating
a collar of grease.
If the machine has been operated for several
days without the lubricating pump, grease
must be pumped in until fresh grease escapes
on all bearing points.
7.5.4 Cab door
To ensure that the door can be opened in all
weather conditions, the door seals must be
brushed with talcum or silicone oil at least every
two months or more frequently if required.
Grease the door hinges and door locks regular-
ly. It is essential to wear safety goggles and
suitable protective clothing during maintenance
work.
