12. BLADE SHARPENING AND SHARPENER ADJUSTMENT
The blade sharpening is carried out with the cutting
unit on, by lowering the proper lever (1, Pict. 9), until
the cutting edge of the rotating blade is reached and
the external edge is sharpened.
Repeat this procedure 3-4 times, for 3-4 seconds.
To carry out a good sharpening, lower the lever
progressively (1, Pict. 9), by avoiding abrupt movements
and an extreme pressure on the lever itself, in order to
protect the emery wheel from wear or damage. The
sharpening procedure must be carried out carefully in
particular when a worn blade is replaced with a new
one. In this case, an extreme pressure on the sharpening
lever may damage the cutting profile of the new blade,
compromising its correct use. Therefore, we suggest
adjusting the emery wheel as follows, after assembling
a new blade on the cutting unit:
·
Disconnect the device from the power supply.
·
Manually lower the sharpener so that the emery
comes into contact with the cutting blade profile (Pict.9).
·
By means of a screwdriver, loosen the screw (2, Pict.10)
·
Manually rotate the threaded bush (3, Pict. 10) bringing the emery and the blade closer.
·
Tighten the screw (2, Pict. 10) and sharpen the blade as previously described.

13. LUBRICATION
Every 3-4 working hours, it is necessary to lubricate the
pair of gears. To carry out this operation, remove the
protective plug “A” located on the motor support of the
cutting unit and fill it with lubricating grease Rasor. Screw
plug “A” again a few turns. Screw plug “A” a few turns
every 2-3 working hours (see picture 11).
The blade must never be dirty with grease or oil.

14. MOTOR BRUSH REPLACEMENT
Since worn motor brushes may cause cutting unit malfunctions (non-start, intermittent start),
check motor brushes periodically. Open the motor cover by unscrewing the 4 screws on the
cutting unit head. Remove the brush metal contacts by means of a flat screwdriver. Remove
brushes and check them: if the graphite has a lenght shorter than 15 mm or it is uneven,
replace it. Close the metal contacts again making sure that they adhere well to the metal
part of the brush. Finally close the motor cover again.
