Running-in instructions
General
IMPORTANT
Check oil pressure and temperature often.
During the running-in period, that is to say the first 100 hours, the
machine must be operated with a certain amount of care. The rea-
son for this is that all bearing surfaces should acquire hard, smooth
surfaces which increase the service life considerably.
The following running-in instructions and intervals apply during the
running-in period.
Engine
The oil should be changed and the oil filters replaced
every 500
hours.
The conditions for the 500 hour interval between oil changes
are:
— The oil filters should be replaced each time the oil is changed.
— The oil filters should meet Volvo Construction Equipment spec-
ifications, which is the case with genuine parts from Volvo Con-
struction Equipment.
— The sulphur content of the engine fuel must not exceed 0.3 per-
cent by weight.
— The oil should be of a quality grade according to
Recommend-
ed lubricants
on page 211.
— The correct oil viscosity for the ambient air temperature is se-
lected according to diagram. See
Recommended lubricants
on page 211.
If any of these conditions cannot be met, or if the machine op-
erates in an acidic or particularly dusty environment, the oil
should be changed and the filters replaced every 250 hours.
Hydraulic system
— The hydraulic return filter, drain filter and servo filter must be
changed after 250 hours operation.
Thereafter drain filter and should be changed every 500 hours,
return filter and servo filter should be changed every 1000
hours.
— The oil of swing drive case and track drive case should be
changed after 500 hours operation.
Thereafter the oil of swing drive case should be changed every
1000 hours.
The oil of track drive case should be changed every 2000
hours.
