FILL/ADD OIL:

This Edger/Trimmer was shipped with a 20 ounce container of SAE30 motor oil This

oit must be added to the engine before operating, Remove the oil fiI_cap and fill

the crankcase,, DO NOT OVERFILL,

NOTE: Engine may already contain some residualoil Check frequentlywhen filling

the crankcase. OIL RECOMMENDATIONS

Only use highquality detergent oil rated with API service classificationSG, Select

the oil's SAE viscosity grade according to your expected operating temperature

Although multi*viscosity oils (5W30, t0W30, etc_)improve starting incold weather, these multi-viscosity oiJswiliresult in increased oil

consumption when used above 32°F. Check your engine oil level more frequently

FILL GAS

Fill the fue! tank with clean, fresh, unleaded grade automotive gasoline. Be sure that the container you pour the gasoline from is

clean and free from dust or other foreign

particles° Never use gasoline that may be stale from long periods of storage in the

container.

L_ CAUTION: Never fillthe gas tank while the engine is runningor hot

Immediately wipe offany spilledgasoline

before attempting to startthe engine,,

/_ CAUTION: Gasoline is flammable and caution must be used when handlingor

enclosed area, Keep away from open flame, electricalspark, and do not smoke

while filling the fuel tank Never fillfuel tank completely; but fillthe tank to within 1/4-1/2

therefore, do not use gasoline for any other purpose°Since many children like the smell

of gasoline, keep itout of their reach

because the fumes are dangerous to inhale, as wel! as being explosive°

WARNING: Experience indicates

that alcohol blended fuels called gasohol or using methanol can attract moisture which

fuel system of _n engine while instorage

To avoid engine problems;the fuel system should be emptied before storage of 30

days or longer. Drain fuel tank, start engine

and let _trun untilfuel lines and carburetor are empty Use fresh fuel next season. See

EDGING TIPS

• Edging is best p+erformedwhen conditions are dry. If the soil Jstowet, dirt becomes

packed in and around the blade causing premature belt wear and decreased

performance°

• tf did does become packed around the blade, stop the engine, remove the spark

plug wire, and remove the packed debris before continuingto edge°

CUSTOMER RESPONSIBILITIES _

• tf very deep edging is required, we recommend that a shallow cut be made

first,then cuts at greater depth until the

desired depth is obtalned.

• Uniform edging can be performed when the blade guide rides on and against the

surface whtch you are edging.

• Edging can be customized by varying the number of passes and by the distance

your blade is from the surface you are edging°
