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 blade and an upper blade. The respective polished blades (fig. 6) must be located on top of each
other for clipping. The blades are assembled as follows: Loosen the tensioning screw (fig. 3, pos. 1, direction A) and place the machine
onto a hard surface, the screws of the lower blade pointing upwards (fig. 5). Loosen the screws and remove the worn blades. Ensure that
the new shear blades are clean. Place the upper blade onto the tapers of the pressure fork (fig. 3, pos. 2) and lightly oil the polished sur-
faces. Then push the lower blade between the loosened screws (fig. 4) until they abut the adjustment plates. Now tighten the screws of the
lower shear blade. Turn the machine around, so that the tensioning nut points upwards. Ensure that the tapers of the pressure fork fit into
the holes of the upper blade (fig. 3, pos. 2). Ensure that the teeth tips of the upper shear blades are located approximately 1,5 – 3,5 mm
behind the polished area of the lower shear blades (fig. 8). Use of the original adjustment plates ensures optimal distance between the
upper and lower blades. Ensure that the lower shear blade is not askew. Firmly tighten both lower shear blade screws (fig. 5) once the
blades have been correctly adjusted.

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. 4–5). 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. 17) and on the drive unit (spare parts list pos. 37) at least at 2 opposite locations with ball bearing grease (viscosity max. 80 mm 2 /s
according to DIN 51562 T1)Lubricate the clipper head according to 3.3 after careful assembly.
