7.1 Important notes
Note!
¯ Gearboxes below 200 Nm are lubricated for life.
¯ The mechanical power transmission system is maintenance−free.
¯ Before commissioning remove transport locking devices and keep them for later
transports.
¯ Take safety measures prior to any operation:
– Disconnect the machine from the mains, ensure standstill of the drive system
and avoid any machine movement.
– That the ambient temperature match the data on the nameplate.
7.2 Maintenance intervals
Stop!
For drive systems: Also observe the maintenance intervals for the other
drive components!
Dust deposits prevent heat to be emitted and cause a high housing temperature. The
gearboxes/geared motors must be purified of dirt and dust at regular intervals.
¯ In the case of gearboxes that are not lubricated for life, the lubricant must be
replaced at regular intervals.
– The type of lubricant is indicated on the nameplate. Replace the lubricant only
with the same type of lubricant.
– The lubricant change depends on the lubricant temperature, see Fig. 11.
1. Measure the lubricant temperature at the drain plug,
2. Add 10 °C,
3. Read the changing interval from the diagram.
