Servicing - Heiniger C12 Instruction Manual

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 clipper blades as long
as the machine is still connected to a power source. Whenever working on the clipper blades/
clipper head, always remove the terminal clamps from the battery first.
4.1 Cleaning
Cleaning the Clipper Head and Clipper Blades
After clipping, remove all oil from the machine by rubbing it down with a dry cloth and care-
fully clean the clipper head and clipper blades with a dry brush. Then oil the parts to prevent
rusting. Even the smallest rust spots on the blades can adversely affect clipping or make it
completely impossible.
4.2 Fitting the Clipper Blade
A pair of clipper blades consists of a lower blade (Illustration 5, Item 2) and an upper blade
(Illustration 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 pressure adjusting screw (Illustration 6) and place the machine on a hard surface
so that the blade fixing screws lie uppermost.
Loosen the two blade fixing screws (Illustration 7) and remove the two old blades.
Illustr. 6+7
Ensure that the new clipper blades are clean. Particular care should be taken to ensure that the
ground surfaces are free of dirt; if not, even newly ground clipper blades will not clip satisfac-
torily.
Place the new upper blade in the guide points of the driving carrier; then place a few drops
of oil on the ground surfaces (Illustration 8). Now push the new lower blade between the loo-
sened screws (Illustration 9).
What is now important is that you adjust the blades against each other in such a way that the
ground surface of the lower blade projects approx. 1.5 - 2.0 mm beyond the tips of the upper

blade (Illustration 10).

Once you have adjusted the clipper blades, set the position of the lower blade and tighten up
the blade fixing screws.
4.3 Resharpening the Clipper Blades
Only work with sharp clipper blades. Replace blunt blades or those with missing teeth. Proper
resharpening can only be done with a special machine and by a trained technician contactable
through your service centre.
