Inverter-operated gearmotors
For gear units with servomotor, the maximum and r.m.s. values of project planning
must be observed during startup. The buyer is obliged to make the data available to
the user.

Checking the oil level
Before startup, make sure that the oil level corresponds to the mounting position. Ob-
serve chapter "Checking the oil level and changing the oil" (→
If the gear unit is equipped with an oil sight glass, you can also determine the oil level
at the oil sight glass.
NOTICE
Damage to the gear unit due to oil leaking from the damaged oil sight glass.
Possible damage to the unit
•
Attach a protective device to prevent the oil sight glass from being damaged by
mechanical impacts.
1. Observe the information at the beginning of chapter
"
2. Check the oil level at the oil sight glass according to the following figure:

4158756363
[1]
The oil level must be within this range.
3. Proceed as follows if the oil level is too low:
•
Open the respective oil fill plug, see chapter
Inspection/maintenance for the
118).
•
Fill in new oil of the same type via the oil fill plug up to the mark.
•
Screw in the oil fill plug.
Before startup, make sure that the oil level corresponds to the mounting position. Ob-
serve chapter "Checking the oil level and changing the oil" (→

Pseudo-leakage at shaft seals
Due to their operating principle, seals between moving surfaces at shaft passages
cannot be completely tight, as a lubricant film must form during operation. The lubric-
ant film between shaft and sealing lip keeps the built-up of heat and wear on the seal-
ing system to a minimum and ensures the intended service life. The optimum sealing
properties are only achieved after the run-in phase.
