FUEL REQUIREMENTS
Use good quality unleaded petrol. The lowest
recommended octane grade is 90 (RON).
IMPORTANT
FUELING ENGINE
Use of alcohol blended fuels (more than 10% al-
cohol) can cause major engine performance
and durability problems.
WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
petrol. Before operation, petrol must be mixed
with a good quality 2--cycle air--cooled engine oil
designed to be mixed at a ratio of 40:1. A 40:1
ratio is obtained by mixing 5 liters of unleaded
petrol with 0,125 liter of oil. DO NOT USE auto-
motive oil or marine oil. These oils will cause en-
gine damage. When mixing fuel, follow instruc-
tions printed on oil container. Once oil is added
to petrol, shake container momentarily to assure
that the fuel is thoroughly mixed. Always read
and follow the safety rules relating to fuel before
fueling your unit.
WARNING: Incorrect use of fuel and/
or lubricants will cause problems such as:
improper clutch engagements, overheat-
ing, vapor lock, power loss, lubrication defi-
ciency, deterioration of fuel lines, gaskets
and internal carburetor components, etc.
Alcohol blended fuels will cause a high ab-
sorption of moisture in the fuel/oil mixture,
causing the separation of oil and fuel.

CARBURETOR ADJUSTMENT
WARNING: Keep others away when
making idle speed adjustments. The trimmer
head will be spinning during most of this pro-
cedure. Wear your protective equipment and
observe all safety precautions. After making
adjustments, the trimmer head must not
move/spin at idle speed.
The carburetor has been carefully set at the
factory. Adjustments may benecessary if you
notice any of the following conditions:
7. With your finger between the lines, wrap
the lines evenly and firmly around the
spool in a clockwise direction.
S Engine will not idle when the throttle is re-
leased.
8. Position the lines in the guide slots.
S The trimmer head moves/spins at idle speed.
12
Make adjustments with the unit supported so
the cutting attachment is off the ground and
will not make contact with any object. Hold
the unit by hand while runningand making ad-
justments. Keep all parts of your body away
from the cutting attachment and muffler.
Idle Speed Adjustment
Allow engine to idle. Adjust speed until engine
runs without trimmer head moving or spinning
(idle speed too fast) or engine stalling (idle
speed too slow).
S Turn idle speed screw clockwise to in-
crease engine speed if engine stalls or dies.
S Turn idle speed screw counterclockwise to
decrease engine speed if trimmer head
moves or spins at idle speed.
If you require further assistanceor are unsure
about performing this procedure, contact an
authorized service dealer.
WARNING: Recheck the idle speed
after each adjustment. The trimmer head
must not move or spin at idle speed to avoid
serious injury to the operator or others.
STORAGE
ENGINE
WARNING: Perform the following
steps after each use:
S Remove spark plug and pour 1 teaspoon of
