5.1
Checking the oil level
Before startup, make sure that the oil level corresponds to the mounting position. Ob-
serve section "Checking the oil level and changing the oil" (page 89).
If the gear unit is equipped with an oil sight glass, you can also determine the oil level at
the oil sight glass.
1. Observe the notes in chapter "Preliminary work regarding inspection/maintenance".
2. Check the oil level at the oil sight glass according to the following figure:
3. Proceed as follows if the oil level is too low:
– Open the respective oil fill plug, see chapter "Inspection/maintenance for the gear
unit".
– 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 section "Checking the oil level and changing the oil" (page 89).
5.2
Pseudo-leakage at shaft seals
Due to their operating principle, seals between moving surfaces at shaft passages can-
not be completely tight, as a lubricant film must form during operation. The lubricant film
between shaft and sealing lip keeps the development of heat and wear on the sealing
system to a minimum and ensures the intended service life. The optimum sealing prop-
erties are only achieved after the run-in phase.
NOTICE
Damage to the gear unit due to oil leaking from the oil sight glass.
Possible damage to the unit.
•
Attach a suitable protective device to exclude damage to the oil sight glass as a
result from shock or blows.
