Store tool and fuel in an area where fuel vapors

cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces,

_,. FUEL MXXTU_E

Your tool 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-cycle, air cooled engines.

The internal design of the 2-cycle engine requires lubrication of moving parts Lubrication is provided when the recommended mixture of gasoline and oil is used

Gasoline must be clean and fresh.After

a short period of time, gasoline wilt chemically break down and form compounds that cause hard starling and damage in 2-cycle engines, o The correct measure of gasoline to oil is very important.

Too much oi! in the mixture wilt fnul the spark plug

IcA_ Too little oil or incorrect oil will cause the engine to overheat and seize.

o Always mix the fuel thoroughly in a container since gasoline and oil do not readily combine Do not

mix gasoline and oil directly in the fuel tank

3. USE THE _'_LLOWINtG :

(16 parts gasoline to I part oil)

WARNING: Alcohol blended fuels, called gasohot

(using ethanol or methanol), can attract moisture which teads to separation and formation of acids during storage.

Acidic gas can damage the fuel system of an engine while in storage, To avoid engine problems, empty the fuel tank before storing for' :30 days or' longer. Use up fuel teft in the carburetor by star_:ing the engine and letting it run until it stops, Use flesh fuel after taldng your unit out of storage_ Never use engine or' carburetor cteane_ products in the fuel tank or permanent engine damage may occm_ See the Storage section for additional information

4. DO NOT riSE: o BIA OIL (Boating Institute of America) --

-- Does not have proper additives for aii-cooled

2-cycle engines and can cause engine damage o AIYrOMO'I IVE OIL --

-- Does not have proper additives for 2-cycle engines and can cause damage

5. HOW TO MLX FUEL AND FNLIL T_K a Pour 1/2 of the regular unleaded gasoline to be used into an approved, marked container'.

_S_U_IONS

1, Bring the engine to cutting speed beforeentering the material to be cut° a Do not run the engine at a higher speed than

necessary. The cuaing line will cut efficiently when the engine is run at less than flail throttle, At lower speeds, there is less engine noise and vibration.

The trimmer line will last longer and will be less likely to "weld" on the spool.

time the bottom of the trimmer head is tapped on the

ground with the engine running at full throttle.

o The most eWmient line length is the maximum length allowed by the line limiter,

o Airways keep the shield in place when the tool is being operated.

To ad_ance line:

1 Operate the engine at full throttle

2 Hold trimmer head parallel to and above the grassy area

3 Lightly tap the bottom of the trimmer head on the ground one time, See Figure 15 Approximately

2 inches of line will be advanced with each tap°

NOTE: If the line is worn down to two inches or less, more than one tap will be required to obtain the most efficient line length

NOTE: Scalping can occur when tapping the bottom of the trimmer head on the ground.

To avoid scalping in critical locations, tap the bottom of the trinamer head in an inconspicuous area when advancing the trimmer line.

The line will easily remove grass and weeds from

also can cut the tender bark of trees or shrubs and scar fences.

To help avoid damage to vegetation or trees with tender bark, shorten line to 4-5 inches and use less than full throttle
