A. FUELING YOUR ENGINE
1. FUEL SAFETY
a. Use only recommended fuel mixtures.
b. Mix and pour fuel outdoors and where there are
no sparks or flames.
c. Use a container approved for fuel.
d. Do not smoke or allow smoking near fuel or the
tool or while using the tool.
e. Wipe up all fuel spills before starting engine,
f. Move at least 10 feet away from fueling site
before starting engine.
.
h.
Stop engine before removing fuel cap.
Empty the fuel tank before storing the tool.
Use up fuel left in the carburetor by starting
the engine and letting the engine run until
it stops.
Store tool and fuel in an area where fuel
vapors cannot reach sparks or open flames
from water heaters, electric motors or swit-
ches, furnaces, etc.
2. FUEL MIXTURE
e Your toot is powered by a two-cycle engine
which requires a fuel mixture of regular
unleaded gasoline and a high quality engine oil
specially made for 2-cycte, air cooled engines.
The internal design ofthe 2-cycle engine requires
lubricationofmoving parts. Lubricationis provided
whenthe recommended mixture ofgasolineandoil
isused.
• Gasoline must be clean and fresh. Aftera short
periodoftime,gasolinewillchemicallybreak down
and form compounds thatcause hardstartingand
damage in 2-cycleengines.
• The correct measure of gasoline to oil is very
important. Toomuch oil in the mixture willfoul the
spark plug.
ICAUTION:I TOOlittle oilwill cause the engine to
overheat and seize,
• Always mix the fuel thoroughly in a container
sincegasolineand oildonotreadilycombine.Donot
mixgasolineand oildirectlyin thefuel tank.
3. USE THE FOLLOWING ONLY:
(16 parts gasoline to I part oil)
-p
4. DO NOT USE:
• BIA OIL (Boating Institute of America) --
-- Does not have proper additives for air-cooled,
2-cycleengines and can causeenginedamage.
• AUTOMOTIVE OIL-
- Does not have proper additives for 2-cycle
engines and cancause damage.
5. HOW TO MIX FUEL AND FILL TANK
a. Pour l/2ofthe regularunleadedgasolineto beused
intoan approved, marked container. Do not mix
gasoline and oil directly inthe fuel tank.
b. Add entire measure of engine oil.
c. Cover container tightly and shake for one minute.
d. Slowly remove fuel container cover.
e. Addremainder of gasoline.
f. Cover container tightly and shake again.
h. Slowlyremovethefuelcap.Referto"Specifications"
for fuel cap location.
i. Fillthetank usinga spoutor funnel.
j. Reinstallthe fuel cap securely.

!CAUTION: JThe air filter must be fitted into the
corners of the housing and under the center tabto
avoid engine damage.
B. FUEL TANK
Never use gasoline that is more than 2 months old
in a fuel mixture. Gasoline begins tobreak downafter
a short,period of time and will form compounds that
cause hard starting and damage in 2-cycle engines.
1. Inspect the unit for fuel leaks each time it is used.
Repair or replaceparts as necessary.
2, Using a fuel mix orgasoline over2 months old will
cause the engine to be difficult or impossible to
start.
° 3. Drain all fuel from the unit or allow unit to run
out of fuel before storing.
