5.2.3.4 Oil level tanks (Option: OT)
NOTICE!
Damage to the gear unit due to low oil level
An oil level below the Min marking may indicate a leak. This may result in damage to the gear unit.
• Find and correct the reason for the low oil level
Check the oil level prior to commissioning. A gear unit which is in operation must be shut down at least
20 to 30 minutes before checking the oil level.
The oil level must be checked with the gear unit at a standstill and with foam-free oil in the installation
position stated on the name plate.
If the oil level is below the minimum level (lower edge of the inspection window), the oil level must be
corrected by topping up with lubricant.
a. Oil level tank and dipstick (standard configuration) (characteristic: cylindrical container): The oil
level must be checked with the aid of the dipstick plug (thread G1¼) in the oil tank. The
sequence is as described in the previous section.
b. Oil level tank and oil level indicator (standard configuration) (characteristic: rectangular
container): The oil level can be seen directly in the window. The correct oil level is the middle of
the oil level indicator.
After correction of the oil level, oil level screws, dipsticks, vents and oil drain screws which have been
unscrewed must be screwed in again and tightened with the appropriate torques (see section 7.4
"Screw tightening torques").
