12.4 Oil change angular gearbox
1. Dismantle the transport device if necessary.
Maintain the tension in the extension spring
by inserting a retaining screw in the frame,
swivel the transport device up and disman-
tle.
2. Dismantle the cover underneath the
gearbox.
3. Place a container under the angular
gearbox.
4. Remove the bleed screw.

12.5 Ventilate the friction clutch
After long periods of disuse and before using
it for the first time, "ventilate" the friction
clutch as follows:
1. Dismantle the friction clutch from the
gearbox input shaft.
2. Precisely measure the fitting length a of the
springs and write it down.
3. Relieve the springs by loosening the nuts.
4. Crank the clutch manually. This loosens
any deposits caused by rust or moisture
between the friction surfaces.
5. Tighten the nuts until the the compression
springs have the indicated fitting length a.
6. Push the friction clutch onto the gearbox
input shaft and fasten.
7. Refasten the all-round protective cover.
High humidity, large amounts of dirt or cleaning
the machine with high-pressure cleaners in-
crease the likelihood of thermal distortion of the
friction linings.
