6.2 Lubricant quantities
Note!
After changing the lubricant, and in particular after the initial filling, the oil level may change
during the first few hours of operation, as the oil galleries and hollow spaces only fill gradually
during operation. The oil level is still within the permissible tolerance.
If at the express request of the customer, an oil inspection glass is installed at an additional
charge, we recommend that the customer corrects the oil level after an operating period of
approx. 2 hours, so that when the gear unit is at a standstill and has cooled down, the oil level
is visible in the inspection glass. Only then, is it possible to check the oil level by means of the
inspection glass.
Note!
The stated filling quantities are guide values. The exact quantities vary according to the exact
gear ratio. When filling, the precise quantity must be observed on the oil level indicator.
Note!
The values in brackets apply for circulation lubrication.
