Fuel and Oil
Type:
The fuel is mixture of gasoline and oil. A
50 to 1 mixture is recommended (50
parts gasoline to 1 part oil). Mix it thor-
oughly before pouring it into the hand-
held edger fuel tank.
CAUTION
Alcohol or "gasohol" may damage the
engine.
The handheld edger is
designed to run on a 50-to-1 mixture of
unleaded regular gasoline (87 octane)
and quality JASO FC class 2-stroke oil
for air-cooled engines.
The octane rating of gasoline is a meas-
ure of its resistance to detonation or
"knocking". Use a gasoline with an
octane rating equal to or higher than that
shown in the table below. The Antiknock
Index is an average of the Research
Octane No. (RON) and the Motor Octane
No. (MON). The Antiknock Index is post-
ed on service station pumps in the
U.S.A. If the Antiknock Index is not post-
ed, be sure the Research Octane No. is
adequate.

WARNING
Gasoline is highly flammable and can
be explosive under certain circum-
stances.
Never overfill tank so that fuel rises into
filler neck. Heat may cause fuel to
expand and overflow through vents in
tank cap. After re-fueling, make sure
cap is closed securely. If gasoline is
spilled on engine or tank, wipe it off
immediately.
Move handheld edger at least 3 m (10
feet) from the fueling place before start-
ing the engine.
Pour the measured amount of 2-stroke oil
into an gasoline container and add gaso-
line to the specified container amount.
Minimum
Rating
Do not use the gasoline that has been
⃝
stored longer than two months.

To ensure proper starting at low ambi-
⃝
ent temperatures, fresh winter grade
fuel must be used.

Filling the Tank:
Level the engine before fueling.
●
Open the fuel tank cap and fill the tank
●
with 50:1 gas/oil pre-mixed fuel.
Pour slowly to avoid "spit back" and
●
allow air to escape from the tank.
Gasoline is a toxic substance. Dispose of
gasoline properly. Contact your local
authorities for approved disposal methods.
