9.10.3 Changing the Oil
9.10.3.1 Main Gear
The oil in the main gear must be changed after the first 250 operating hours and sub-
sequently every 1000 operating hours or once a year.
To carry out an oil change, the oil had better be as warm as possible
from operating.
To change the oil:
Shut down the rotary drive.
Place the rotary drive such that drain screws
(1) are in their lowermost position.
Unscrew filler screws (2).
Have an oil collecting container ready.
Fit a plastic tube or hose of suitable size and
length from the drain to the container!
Unscrew drain screw(s) (1) and let the oil out.
Danger of scalding!
Hot gear oil can cause severe injury!
Inspect magnets on all drain screws and on magnetic sticks for gear abrasives, and
clean the screws (see also sect. "Oil Sampling").
Check the mounting bolts of the hollow shaft (see sect. "Hollow Shaft
Mounting Bolts").
