4 Maintenance
NOTE!
Before commencing any maintenance work disconnect the elec-
trical power supply by pulling out the plug.
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/clipper head, always first disconnect the
power supply.
4.1 Cleaning
Cleaning the shearing head and clipper blades
After finishing the shearing, remove oil from the machine by wiping 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 shearing blades impair shearing or make it completely impossible.
4.2 Mounting the shearing blades
A pair of shearing blades consists of a lower blade (Fig. 6, item 2) and up-
per blade (Fig. 6, item 1). When mounting the blades, make sure that the
correct surfaces are placed on top of each other. The blades are mounted
as follows:
Loosen the shearing pressure adjustment knob (Fig. 7) and place the
X
machine on a hard surface so that the blade fixing screws (Fig. 8) are
facing upwards.
Loosen the screws and remove the two old shearing blades.
X
Make sure that the new shearing blades are clean. In particular, make
X
sure that the sanded surfaces are free of dirt. Otherwise, satisfactory
shearing performance cannot be achieved even with newly sharpened
shearing blades.
Place the new upper blade in the driving cones of the chicken feet
X
(Fig. 9 + Fig. 3, item 2) and push the new comb plate between the loos-
ened screws (Fig. 10).
Now tighten the blade fixing screws until you can just move the new
X
comb plate sideways by hand.
Now turn the machine over so that the shearing pressure adjustment
X
knob is pointing upwards again.
It is now important that you place the blades on top of each other so that
X
the ground surface of the comb blade protrudes approx. 1.5 - 2.0 mm
above the tips of the upper blade (Fig. 11).
Once you have adjusted the shearing blades, fix the position of the comb
X
plate and tighten the blade fixing screws firmly.
