Part C Maintenance
C3.2 Check fluid level in oil tank
If fluid volume is too low
– the operating temperature increases,
– which leads to air inclusions,
– and results in the hydraulic cylinder
being extended jerkily.
Therefore:
– keep the oil level display device clean.
– continually monitor the oil level.
– immediately refill the missing hydraulic
oil.
– determine the cause of excessive oil
consumption.
C3 Maintenance and Repairs
C3.3 Check oil temperature and oil
level
–
The operating temperature of the
hydraulic oil increases with an in-
crease in the outside temperature.
–
Switch off the hydraulic pump if
the oil temperature goes over 70 °C.
–
Determine the cause of the over-
heating (e.g. no pressureless flow,
outside temperature is too high).
3.5
Fig. 21: Oil temperature and oil level
The thermometer (3.5) gives the
following readings:
– operating temperature of the oil.
– regularly check the oil temperature
during operations.
– oil level indicator.
– The oil level can vary depending on the
type, quantity and size of the consumer.
– Recommended operating temperature
of the hydraulic oil: 45° C (average
temperature of the hydraulic oil in the
tank).
