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.
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) ensur-
ing the tabs (A) are pointing downwards as illustrated,
ensure it clicks firmly into its airtight position.

WARNING: when the engine is switched off
rotating parts, blade or nylon string head, will
keep on rotating for a few seconds. Hold the
machine until all parts come to a standstill.
N.B. In an emergency the above mentioned
delay in stopping may be shortened by
touching blade parallel on the ground.
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.
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 Dealer every 100 working
hours.
This will reduce the possibility 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.
