4 Servicing

Before starting any servicing work, disconnect the power supply; remove the terminal clamps
from the storage battery.
Even with the machine switched off, do not handle the area round the shearing blades as
long as the machine is still connected to a power source. Whenever working on the shearing
blades/shearing head, always remove the terminal clamps from the battery first.

4.1 Cleaning

Cleaning the Shearing Head and Shearing Blades
After shearing, remove all oil from the machine by rubbing it down with a dry cloth and
carefully clean the shearing head and shearing blades with a dry brush. Then oil the parts to
prevent rusting. Even the smallest rust spots on the blades can adversely affect shearing or
make it completely impossible.

4.2 Fitting the Shearing Blade

A pair of shearing blades consists of a comb plate (Illustration 5, Item 2) and an cutter (Illust-
ration 5, Item 1). When fitting the blades care should be taken to ensure that the correct
surfaces come to rest against each other. The blades are fitted as follows:
Illustr. 5
Loosen the tension nut (Illustration 6) and place the machine on a hard surface so that the
blade fixing screws lie uppermost. Slacken off the screws and remove both the old shearing
blades.
Illustr. 6/7
Ensure that the new shearing blades are clean. Particular care should be taken to ensure that
the ground surfaces are free of dirt; if not, even newly ground shearing blades will not shear
satisfactorily.
Place the new cutter in the pressure yoke's carrier cones (Illustrations 8 + 3, Item 2) and push
the new comb plate between the loosened screws (Illustration 9). Now tighten the blade
fixing screws until you can just move the new comb plate sideways by hand.
Now turn the machine over so that the tension nut is again uppermost.
What is now important is that you rest the blades against each other in such a way that the
Illustr.
ground surface of the comb plate projects approx. 1.5 - 2.0 mm beyond the tips of the
8/9/10
upper blade (Illustration 10).
Once you have adjusted the shearing blades, set the position of the comb plate and tighten
up the blade fixing screws.
Check that the shearing blades have been correctly fitted and that the pressure yoke's carrier
cones (Illustration 3, Item 2) are situated in the holes provided in the cutter. Now tighten up
the tension nut until the cutter is pressed against the comb plate and you can feel a slight
resistance.
