MAINTENANCE AND REPAIR
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.
CYLINDER AND SILENCER
To reduce fire risks, periodically clean the cylinder flaps
with compressed air and clear the silencer area to get rid
of sawdust, branches, leaves or other debris.
STARTING SYSTEM
To avoid overheating and damage to the engine, always
keep the cooling air vents clean and free of sawdust
and debris.
The starter rope must be replaced as soon as it shows
signs of wear.
NUTS AND SCREWS
Periodically check that all the nuts and screws are se-
curely tightened and the handgrips are tightly fastened.
AIR FILTER (Fig. 15)
To clean the air filter:
1. Remove the fixing screw (3) of the air filter cover (1).
2. Clean the filter (2) using soap and water.
Never use petrol or benzene !
3. Let the Filter dry in the air.
4. Now put the filter in again proceeding the other way
round.
NOTE: Replace the filter if it is worn out, damaged or
too dirty.
CARBURETTOR SETTINGS
The carburettor has an optimised setting 'ex works'. If
any further adjustments should be required contact your
competent customer service.
WARNING! The cutting device must not move
when the engine is running idle. If the cutting device
moves when the engine is running idle, contact your
dealer to correctly regulate the engine.
SPARK PLUG
1. Spark plug air gap: 0,5 mm (Fig. 16)
2. Tighten the spark plug with a torque of 12-15Nm. Put
the spark plug connector on the spark plug.
ANGLE TRANSMISSION (Fig. 17)
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 (Fig. 18)
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. 18:
A = Incorrect sharpening
B = Sharpening limits
C = Incorrect and unequal angles
It is important to retain the correct balance after shar-
pening.
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 (Fig. 19)
- Follow the sequence indicated in the figure.
SHARPENING THE CORD CUTTER (Fig. 20)
1. Remove the cutter (1) from the protection cover (3)
(Fig. 20).
2. Put the cutter into a vice and fix it firmly. Sharpen the
cutter using a flat file. File with care and keep the
sharpening angle. Always file in one direction only.
STORAGE
After every work stint, clean the machine thoroughly to
remove all dust and debris, and repair or replace any
faulty parts.
The machine must be stored in a dry place away from the
elements and with the cover correctly fitted.
LONG PERIODS OF DISUSE
IMPORTANT: If you are not going to use the machine for
a period of more than 2-3 months, we recommend you
do a few things before putting it away. This will make it
easier when you want to use the machine again and will
also prevent permanent damage to the engine.
STORAGE
1. Follow all aforementioned maintenance instructions.
2. Thoroughly clean the trimmer and grease the metal
parts.
3. Empty the fuel tank and screw the tank cap back on.
4. After the tank has been emptied, start the engine.
5. Let the engine idle until it stops to free the carburettor
from fuel.
6. Let the engine cool down (about 5 minutes).
7. Remove the spark plug using a spark plug wrench.
8. Fill a tea spoon of pure 2-stroke oil into the combustion
chamber. Pull the starter rope several times slowly to
distribute the oil inside the engine. Put the spark plug
back in.
