To adjust the idle speed, however, proceed as fol-
lows:
With engine running and warm, slowly turn screw
‘T’ clockwise until the engine runs smoothly with
a consistent noise level but without making the
cutting head rotate.
If the cutting attachment does move or the engine
runs too fast, slowly turn screw ‘T’ in an anti-
clockwise direction until the correct speed is
obtained.
Precise numerical engine speed settings are men-
tioned in the technical detail chart in the front of
the owner’s manual.
L. Carburettor adjustment
M. Regular maintenance
From time to time ensure all screws are tight.
Replace damaged, worn, cracked or warped
blades. Always make sure nylon string head or
blade have been assembled correctly (see sec-
tions NYLON STRING HEAD and BLADE
ASSEMBLY) and blade fastener is tightened.
1) AIR FILTER CLEANING
(at least every 25 working hours).
A dust clogged air filter may cause carburetor
problems.
This may prevent the engine from reaching its
maximum speed and cause high fuel con-
sumption and/or difficult starting.
Remove filter cover as shown in figure 1.
Carefully clean the inside of filter box. The filter
can also be cleaned with compressed air.
N.B. Slide the air filter back into its location (C)
ensuring the tabs (A) are pointing downwards as
illustrated, ensure it clicks firmly into its airtight
position.
2)
Every 50 working hours inject the gearcase with
gear grease under high pressure through hole
(C).
3) SPARK PLUG
From time to time (at least every 50 hours)
remove and clean the spark plug and check
the electrode gap (0,5/0,6 mm.). Replace spark
plug about every 100 working hours or whenever
it is extremely encrusted. Heavily encrusted
electrodes can result from wrong fuel mixture
(too much oil in the petrol) or a poor quality of
oil in the fuel mix. Check and correct.
4) FUEL FILTER
To change fuel filter remove the tank cap and
pull out the filter with a piece of bent wire or
long forceps. Contact your Service Station for
general servicing and cleaning of internal parts
at least once a year.This will reduce the possi-
bility of unexpected problems and will ensure
maximum product life and efficiency.
REGULARLY: it is important, in order to avoid
engine overheating, to remove dust and dirt
from slots, gaps and from in between cylinder
fins using a wooden scraper.
LONG STORAGE: empty fuel tank and run
engine until dry.
Store trimmer in a dry place.
STARTING A WARM ENGINE
Position the on/off switch to the I (ON) position.
Squeeze the primer bulb (C) several times until
you see fuel begin to return back through tube
(D) to the fuel tank. Push the decompression
valve (B) down if your model is fitted with one.
Pull the starter handle until the engine runs.
5) STOPPING THE ENGINE
Push the on/off switch to the STOP position.
WARNING: After the engine has been
switched off, the rotating cutting attachment,
blade or string head, will continue to rotate for
a few seconds due to their inertia. Continue to
hold the machine firmly off the ground until it
stops completely. Keep your hands away whilst
it is moving.
N.B. In an emergency, the cutting
attachment can be stopped quickly by
touching it parallel to the ground after
moving the switch to the «STOP» position.
