Operation
Observe the instructions in section 3, "Safety instructions", in section 9, "Faults, causes and remedy", and
in section 10, "Maintenance and repair"!

General
To achieve a satisfactory and troublefree operation of the equipment, be certain to observe the operating
values specified in section 1, "Technical Data", as well as the information given in the operating instructions
of the oilsupply system, if applicable.
During operation the gear unit must be monitored for:
•
Excessive operating temperature
•
Oil pressure of the oilsupply system
•
Change in gear noise
•
Possible oil leakage at the housing and shaft seals
•
Correct oil level (see also section 7 "Startup")
8.2
Oil level
To check the oil level, stop operation of the gear unit.
When the oil is hot, the oil level may slightly exceed the upper mark of the oilsight glass of
angular oillevel indicator.
It must not be allowed to fall below the lower mark. If necessary, top up to the correct
level.
8.3
Irregularities
The drive unit must be switched off at once,
– if irregularities are found during the operation
or
– if the pressure monitoring device in the oilcooling system triggers alarm
(only with correspondingly equipped gear unit).
Determine the cause of the fault, using table 9, "Faults, causes and remedy"
(see item 9.2).
Table 9, "Faults, causes and remedy", contains a list of possible faults, their causes
and suggested remedies.
If the cause cannot be found, a specialist from one of our customerservice centres
should be called in (see section 2, "General notes").
Unless otherwise agreed, the gear unit is designed
for continuous operation at an operating
temperature of:
80 °C (applies to mineral oil)
Shortterm temperatures of up to
90 °C are permitted; see section 10.
(min. 1.5 bar).
