tool or while using the tool.

e. Wipe up all fuel spills before starting engine,

d. Do not smoke or allow smoking near fuel or the

f. Move at least 10 feet away from fueling site

before starting engine. Stop engine before removing fuel cap.

3. USE THE FOLLOWING ONLY:

(16 parts gasoline to I part oil)

-p

J 1

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 that cause hardstartingand damage in 2-cycleengines.

• The correct measure of gasoline to oil is very

important. Toomuch oil in the mixture willfoul the

spark plug.

4. DO NOT USE:

• BIA OIL (Boating Institute of America) --

-- Does not have proper additives for air-cooled,

2-cycleengines andcan 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 regular unleadedgasolineto beused

intoan approved, marked container. Do not mix

gasoline and oil directly in the 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. Add remainder of gasoline.

ICAUTION:I TOOlittle oilwill cause the engine to

overheat and seize,

• Always mix the fuel thoroughly in a container

sincegasolineand oildonotreadilycombine.Donot

mixgasoline and oildirectlyin thefuel tank.

f. Cover container tightly and shake again.

h. Slowlyremovethefuel cap.Referto"Specifications"

for fuel cap location. i. Fillthetank usinga spoutor funnel. j. Reinstallthe fuel cap securely.
