to cool. DO NOT smoke near the replenishment
area.
Make sure that the area is well ventilated and
that there are no flames or sparks, and that
there is no pilot light on any type of device.
ATTENTION: running on gasoline only will cause
the engine to seize. Use gasoline-oil mixture.
2 - stroke Engines requires a gasoline-oil mix-
ture. Gasoline and engine oil mixing ratio is 25:1
(Gasoline; 25, 2 - stroke engine Oil; 1).
Pour the 2 - stroke engine oil and the gasoline
into an appropriate container with the ratio
shown above, and shake it thoroughly to avoid
the separation of them.
And then, pour it into the fuel tank.
IMPORTANT: mix only the amount needed to
work. Prepare a new mix every time you need to
refuel the fuel tank. Leaving the mixture stored
for long periods of time causes the oil to seize,
this can cause serious damage to the compo-
nents or the engine.
FUEL TYPE AND OCTANE RATING
When mixing gasoline with two-cycle engine
oil, use only gasoline that does not contain
ethanol or methanol (types of alcohol). This will
help prevent possible damage to the fuel lines
of the engine and other parts of the engine.
Do not mix gasoline and oil directly in the en-
gine fuel tank.
ATTENTION: use gasoline marked 91 octane or
higher, knowing that it is of good quality.
CHECK THESE POINTS BEFORE OPERATING
1. Check for any missing nuts or bolts.
2. Check the air filter. Clean it in case of dirt be-
fore any work.
3. Check if the protector is properly positioned
and not loose.
4. Check if the fuel does not show any leakage.
5. Check that the blades are not worn.
STARTING THE ENGINE
FUELING
Place the engine on a level surface before add-
ing the fuel.
• Open the fuel filler flap and fill the tank with a
pre-mix of 25 parts of gasoline for 1 oil.
• Pour the mixture slowly to prevent it from
spilling, and thus allow air to escape from the
fuel tank.
• Close the lid firmly.
IMPORTANT: never fill the tank so the fuel
level rises into the filler neck. If the tank is over-
filled, heat may cause the fuel to expand and
overflow through the vents in the tank cap.
E N G L I S H •
After refueling, make sure the fuel tank cap is
closed securely. If gasoline is spilled on the fuel
tank, wipe it off immediately.
WARNING: the engine exhaust of this prod-
uct contains chemicals known to cause cancer,
birth defects or other reproductive harm.
STARTING
COLD START
1. Move the switch (fig. 1-1) to the "START" po-
sition.
2. Press the primer cylinder (fig. 2-1) 7 to 10
times or until you see fuel passing through the
tubes that feed the engine.
3. Move the choke lever (fig. 2-2) to the closed
position .
4. Press the throttle trigger (fig. 1-2) and then
press the throttle lock button (fig. 1-3) to keep
it accelerated.

5. Pull the starter rope until the engine starts
to light.
6. Push the choke lever inwards (excessive start-
ing will cause engine choking, which will make
starting difficult).
7. Pull the ignition cable until the engine starts
completely.
8. When the engine is running, remove the
starter by turning the choke lever to "RUN"
9. Deactivate the throttle lock (if activated) by
briefly pressing the throttle trigger.
10. Allow the engine to warm up for a few min-
utes before using it.
IMPORTANT: pulling the starter rope repeat-
edly with the choke on can choke the engine
and make starting difficult.
NOTICE: if you have choked the engine, re-
move the spark plug and gently pull the starting
rope to remove excess fuel; Then dry the spark
plug electrodes and put them back in the en-
gine.
STARTING THE ENGINE IN HOT
1. Set the choke lever to the RUN position
• If the fuel tank still has fuel, pull the rope from
the starter one to three times and the engine
should start.
• If the fuel tank has been emptied, replenish
and repeat steps 1,2 and 7.
