OPERATION INSTRUCTIONS

FUEL AND REFUELING
IMPORTANT: Gasoline is extremely flamma-
ble and can be explosive under certain condi-
tions, c reating the potential for serious burns.
Turn the ignition switch to "OFF". Do not
smoke.
Make sure the area is well-ventilated and f ree
from any source of flame or sparks; this inc
ludes any appliance with a pilot light.
ATTENTION: Running on gasoline only will
cause the engine to seize. Use gasoline-oil mix-
ture.
2-stroke Engines requires a gasoline-oil mix-
ture. Gasoline and engine oil mixing ratio is
40:1 (Gasoline; 40, 2-stroke engine Oil; 1).
Pour the 2-stroke en-
gine oil and the gaso-
line into an appropri-
ate container with the
ratio shown above,
and shake it thor-
oughly 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 mix-
ture stored for long periods of time causes the
oil to seize, this can cause serious damage to
the components or the engine.
Fuel type and octane rating
Use clean, fresh unleaded gasoline with etha-
nol volume content not more than 10% and
an octane rating equal to or higher than that
shown in the table.

Rating
ATTENTION: Do not use any fuel that contains
more ethanol or other oxygenates than speci-
fied for E10 fuel* in this engine. Damage to
the engine and fuel system, or engine starting
and/or performance problems may result from
the use of improper fuel.
* E10 means fuel containing up to 10% etha-
nol as specified by European directive.
STARTING THE ENGINE
FUELING
Level the engine before fueling.
• Open the fuel tank cap and fill the fuel tank
with 40:1 gas/oil pre-mixed fuel.
• Pour slowly to avoid "spill back" and allow
air to escape from the fuel tank.
• Close the tank cap securely by turning it
clockwise as far as it will go.
IMPORTANT: Never fill the tank so the fuel
level rises into the filler neck. If the tank is
overfilled, heat may cause the fuel to expand
and overflow through the vents in the tank
cap. After refueling, make sure the fuel tank
cap is closed securely. If gasoline is spilled on
the fuel tank, wipe it off immediately.
STARTING
NOTE: To minimize load on engine during
starting and warmup, trim excess trimming
line to 13 cm.
STARTING A COLD ENGINE
1. Place trimmer on firm flat surface.
2. Move ignition switch to the "RUN (l)" posi-
tion.
