8. Maintenance
■ BLADES
Oil blades each gas tank filling (MA5).
• Make sure that the blade bolts are well
tightened.
• The blade assembly is designed to
automatically compensate for any play
between the blades.
■ SHARPENING (MA6)
Always keep the file or sharpener at an angle of
45° to the blade, and:
• Always grind in the direction of the cutting edge;
• Note: files cut only in one direction; lift the file
from the blade when returning to start a new
pass;
• Remove all burr from the edge of the blade with
a slip stone;
• Remove as little material as possible;
• Before refitting the sharpened blades, remove
filings and then apply grease.
Do not try to sharpen a damaged blade: change it
or take it to a Service dealer.
■ REDUCTION GEARBOX
Refill gear housing every 20 working hours (MA7).
Use greese pump. Feed greese until it comes out
of the base of blades.
■ PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE
1. Tighten all screws, bolts, and fittings.
2. Check to see if any oil or grease has worked its
way in between the clutch lining and drum, and if
it has wipe it away using oil-free, lead-free
gasoline.
