7.7.4.2 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
â–º
Attach filler pump to grease nipple (183/1).
â–º
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 sev-
eral days without the lubricating pump,
grease must be pumped in until fresh
grease escapes on all bearing points.
