7.9.2 Lifter gears for lifting rollers
Check the oil level of the gear units (3 units) on the lifting unit daily.
For this purpose, fully lower the lifting unit.
Change the oil for the first time after 50 operating hours. Please find the subsequent
oil change intervals in the maintenance table.
Change the oil only with the gear oil at operating temperature.
For all gear units of the lifting unit:
Lower the lifter as far as possible for the left front lifter gears, and lower the lifter as far
as possible for the rear lifter gears and let the oil drain through the oil drain screws into
a sufficiently large oil-proof container. Reinsert the oil drain screws and tighten them.
Lower the lifter completely.
Fill in fresh gear oil through the oil filling screw until the inspection glasses are half
filled up.
Close the oil filling openings with the screw plugs.
