12. BLADE SHARPENING
13. LUBRICATION
Every 3-4 working days, it is necessary to lubricate the
pair of gears. To carry out this operation, remove
protective plug “A” located on the motor support of
the cutting unit and fill it with lubricating grease Rasor
®
.
Screw plug “A” again few turns. Screw plug “A” some
turns every 2-3 working days (see picture 11).
The blade must never be dirty with grease or oil.
WARNING
After many hours of a continuative use of the cutting
unit or if it would not be able to cut anymore, it is
necessary to sharpen the blade.
To carry out this operation, start the blade and press
sharpener “2” located on it 3-4 seconds (by pressing
push button “1”, as shown in picture 9).
Repeat the operation 2-3 times.
If the sharpening operation is not effective, check the
wear of emery grinding wheel “3” (see picture 10).
If grinding wheel “3” is too worn or dirty, replace it.
14. MOTOR BRUSH REPLACEMENT
Worn motor brushes could create a cutting unit malfunction (no starting, intermittent start,
etc.), therefore it should be better to verify their wear periodically.
Open the motor cover by unscrewing 4 screws “4” on the cutting unit head (see picture 12).
Remove the metal contacts that close the brushes with a slotted screwdriver (see picture 13).
Remove the brushes and check their wear: if the graphite has a lenght shorter than 15 mm or
it is uneven, replace it (see picture 14).
Close the metal contacts again by making sure that they adhere well to the metal part of the
brush. Finally close the motor cover again.
