4. Maintenance

Turn the machine off and pull the power supply plug before beginning maintenance work. Always disconnect the power supply first before
working on the shear blades/clipper head. Do not touch the shear blade area even if the machine is switched off as long as the clipper is still
connected to the current supply.

4.1 Cleaning

After having finished clipping wipe the oil off the machine, clipping head and shear blades with a dry cloth and remove the hairs with a dry
paintbrush or brush. Then lightly oil all parts to prevent rusting. Note that even the smallest rust spots impair clipping considerably or even
render this completely impossible.

4.2 Shear blade assembly

The shear blade set consists of a lower plate and an upper plate (fig. 4). When assembling the shear blades pay attention that the correct
plates lie on top of one another. Assemble the blades as follows: Loosen the clipper tension screw (fig. 5) and put the clipper onto a hard
surface, so that the blade fastening screws look upwards. Loosen the blade fastening screws (fig. 6) and remove the two old blades. Ensure
that the new shear blades are clean. Pay particular attention to the fact that the sharpened areas are dirt-free; it is otherwise impossible
to achieve a satisfactory clipping result even with newly sharpened shear blades. Put the new upper plate into the swing head guides and
then put some drops of oil onto the sharpened areas (fig. 7). Now push the new lower plate in between the released screws (fig. 8). It is
important that the blades lie on each other in such a way that the sharpened area of the lower plate projects over the tips of the upper plate
by approximately 3.0 - 5.0 mm (fig. 8)! As soon as you have adjusted the shear blades, fixate the lower plate position and tighten the blade
fastening screws.

4.3 Resharpening the blades

Resharpening shear blades correctly is only possible with special machines and by the specialised trade. Only use sharp shear blades.
Defective blades with broken off teeth or blunt blades must be replaced.

4.4 Cleaning the air supply cap

The air supply covers are located on both rear sides of the machine drive unit. Dismantle the air filters for cleaning. Grasp the hollow in the
housing and push the air supply covers out to the rear (fig. 7). Blow out the filter fabric in the supply air cover from inwards to outwards.
Align the covers on the upper edge of the drive housing and slide on.It is essential to clean the air filters regularly to ensure sufficient motor
cooling. Make sure that no foreign matter gets into the machine when cleaning the air filter. Never use the clipper without an air filter.

4.5 Storing the clipper

Between clippings always keep the well-cleaned and lubricated clipper in the supplied case in a dry location, which is not accessible to
children. Do not switch the machine on, if you suspect that liquids could have entered. There is danger of an electric shock or short-circuit.
Have the machine serviced!

4.6 Cleaning the clipper head

Clean the clipper head after a few days use. Dismantle the cutter plates (fig. 5-8). Release both screws (spare parts list pos. 22) (Phillips
screwdriver Ph2 not contained in the scope of delivery) and remove the clipper head from the drive unit. Now clean the interior of the clipper
head and the other components thoroughly with a brush and a paintbrush. Grease the gears on the eccentric shaft (spare parts list
pos. 8) and on the drive unit (spare parts list pos. 37) at least at 2 opposite locations with ball bearing grease (viscosity max. 80 mm /s
2
according to DIN 51562 T1). Lubricate the clipper head according to 3.3 after careful assembly.
