in section 10, "Maintenance and repair"!
8.1 General
The coating must not carry an electrostatic charge!
The operator must ensure that highly effective mechanisms which can set up a charge
in the coating are safely avoided.
To achieve a satisfactory and troublefree operation of the equipment, be certain to observe the working
values specified in section 1, "Technical data".
During operation the gear unit must be monitored for:
Oil temperature The gear unit is designed for an operating temperature
in continuous operation of:
100 °C (synthetic oil only)
Shortterm temperatures of up to 130 °C are permitted;
see also section 10.
Correct oil level (see section 7, "Startup")
Changes in gear noise
Possible oil leakage at the housing and shaft seals
Bearing vibrations with present measuring sequence.
If any safety device has triggered, it must only be possible to start the drive again after
releasing the reclosing interlock. The operator must ensure this.
8.2 Oil level
To check the oil level, stop operation of the gear unit.
Depending on the features the following oil levels apply :
– Middle of the oilsight glass
– Upper mark on the oil dipstick
When the oil is hot, the oillevel marks may be slightly exceeded. It must in no case be
allowed to fall below the 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 oilsupply system triggers alarm
(only with correspondingly equipped gear units).
Determine the cause of the fault, using table 11, "Faults, causes and remedy"
(see item 9.2).
Table 11, "Faults, causes and remedy", contains a list of possible faults, their causes
and suggested remedies.
