• Adjusting line length when working
This machine is fitted with a "Tap & Go" head.
To release more line, tap the cutting line head against
the round with the engine at top speed: the line will be
released automatically and the knife cut off the excess
length.
End of Operation
When you have finished your work:
- Switch off the engine as indicated above (Chap. 6).
- Wait for the cutting device to stop and fit the blade
guard.
Maintenance and Storage
Correct maintenance is essential to maintain the original
efficiency and safety of the machine over time.
WARNING! During maintenance operations:
- Remove the spark plug cap.
- Wait until the engine is sufficiently cold.
- Use protective gloves when handling the blades.
- Keep the blade protection device on, except when
intervening directly on the blade.
- Never dispose of oils, fuel or other polluting mate-
rials in unauthorised places.
ANGLE TRANSMISSION
Lubricate with lithium-based grease.
Remove the screw (1) and put in the grease, turning the
shaft manually until grease emerges, then replace the
screw (1).
Sharpening the 3 point blade
WARNING! Use protective gloves. If sharpening
is done without removing the blade, disconnect the
spark plug cap.
Sharpening must be done taking account of the type of
blade and cutting edges, using a flat file and working all
the points equally.
The references for correct sharpening are given in Fig. 19:
A = Incorrect sharpening
B = Sharpening limits
C = Incorrect and unequal angles
It is important to retain the correct balance after sharp-
ening.
3 point blades can be used from both sides. When one
side of the points is worn, the blade can be turned and
the other side used.
WARNING! The blade must never be repaired,
but must be replaced as soon as signs of breaking
are noted or the sharpening limit is exceeded.
Head line replacement
- Follow the sequence indicated in the figure.
