RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the

_crankcase is extremely important. Check the

oil before each use and change the oil

regularly. Failure to use the correct oil, or

using dirty oil, can cause premature engine wear and

failure.

Use a high-quality SAE 30 weight oil of API (American

Petroleum Institute) service class SG, SF, SH.

ADDING OIL TO CRANKCASE - INITIAL USE

NOTE: This unit is shipped without being filled with oil.

In order to avoid damage to the unit, put oil in

the crankcase before attempting to start unit.

Your unit is supplied with one 3.4 fluid oz. (100 mL)

bottle of SAE 30 SF, SG, SH oil (Fig. 1).

NOTE: Save the bottle to measure the correct amount

for future oi! changes.

1. Open the bottle of oil (Fig. 1).

NOTE: Never add oil to the fuel or fuel tank.

5. Wipe up any oil that may have spilled and reinstall

the oil fill plug /dipstick.

The importance of checking and maintaining the proper

oil level in the crankcase cannot be overemphasized.

Check oil before each use and change as needed. See

Changing the Oil Pg. 17.

RECOMMENDED FUEL TYPE

OId fuel is usually the main reason for the unit

not running properly. Be sure to use fresh,

clean, unleaded Gasoline.

NOTE; This is a four cycle engine. In order to avoid

damage to the unit, do not mix oil with

Gasoline,

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and

oxygenates such as ethanol, methanol or MTBE (ether).

Alcohol-blended fuel absorbs water. As little as 1%

water in the fuel can make fuel and oil separate or form

acids when stored. Use fresh fuel (less than 60 days

old), when using alcohol-blended fuel.

Using Blended Fuels

If you choose to use a blended fuel, or its use is

unavoidable, follow recommended precautions.

•Always use fresh unleaded gasoline

• Use the fuel additive STA-BIL ® or an equivalent.

• Drain tank and run the engine dry before storing unit.

Using Fuel Additives

The use of fuel additives, such as STA-BIL ® Gas

Stabilizer or an equivalent, will inhibit corrosion and

minimize the formation of gum deposits. Using a fuel

additive can keep fuel from forming harmful deposits in

the carburetor for up to six (6) months. Add 0.8 oz.

(23 ml.) of fuel additive per gallon of fuel according to the

instructions on the container. NEVER add fuel additives

directly to the unit's gas tank.

FUELING UNIT

WARNING: Gasoline is extremely flammable

and its vapors can explode if ignited. To

avoid serious personal injury, always stop the

engine and allow it to coot before filling the

fuel tank. Do not smoke while filling the tank.

Keep sparks and open flames away from the

area.

1. Remove gas cap (Fig. 4).

WARNING: Remove gas cap slowly to avoid

injury from gasoline spray.

2. Place spout of gas container into the fill hole on the

gas tank (Fig. 4) and fill tank.

WARNING: Add gasoline in a clean, well -]

ventilated area outdoors. Avoid creating a

source of ignition for spilt fuel.

NOTE: Do not overfill tank.

4Screws

ADJUSTING TRIMMING LINE LENGTH

The Bump Head TM cutting attachment al!ows you to

release trimming line without stopping the engine. To

release more line, lightly tap the cutting attachment on

the ground (Fig. !3) while operating the trimmer at high

speed.

NOTE: Always keep the trimming line fully extended.

Line release becomes more difficult as cutting

line becomes shorter

Fig. 13 ........

Each time the head is bumped, about 1 inch (25.4 mm.)

of trimming line is released. A blade in the cutting

attachment shield will cut the iine to the proper length if

excess line is released.

For best results, tap the Bump Head TM on bare ground

or hard soil. If line release is attempted intall grass, the

engine may stall. Always keep the trimming line fully

extended, Line release becomes more difficult as the

cutting line becomes shorter,

NOTE; Do not rest the Bump Head TM on the ground.

CAUTION: Do not remove or alter the line ]

cutting blade assembly. Excessive line length r

will make the clutch overheat. This may lead |

to serious personal iniury or damage to the

unit. /

Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence

posts

- Fig. 12 ...................

TIPS FOR BEST TRIMMING RESULTS

• Keep the cutting attachment parallel to the ground.

• Do not force the cutting attachment. Allow the tip of

the line to do the cutting, especially along walls.

Cutting with more than the tip will reduce cutting effi-

ciency and may overload the engine.

• Cut grass over 8 in. (200 mm.) by working from top

to bottom in small increments to avoid premature

line wear or engine drag.

• Cut from left to right whenever possible. Cutting to

the right improves the unit's cutting efficiency.

Clippings are thrown away from the operator.

• Slowly move the trimmer into and out of the cutting

area at the desired height. Move either in e forward-

backward or side-to-side motion. Cutting shorter

lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon;

• Following the previous trimming techniques

• What vegetation is being cut

• Where it's being cut

For example, the line will wear faster when trimming

against a foundation wal! as opposed to trimming

around a tree.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all

vegetation around trees, posts, fences, etc,

Rotate the whole unit so that the cutting attachment is at

a 30° angle to the ground (Fig. 14).

unit. An authorized service dealer should make

carburetor adjustments.

Check Fuel Mixture

Old fuel is usually the main reason for the unit not

running properly. Drain and refill the tank with clean,

fresh unleaded fuel prior to doing any adjustments. Refer

to Oil and Fuel Information.

Clean Air Filter

The condition of the air filter is important to the opera-

tion of the uniL A dirty air filter will restrict air flow and

change the air/fuel mixture. This is often mistaken for an

out of adjustment carburetor. Check the condition of the

air filter before adjusting the idle speed screw. Refer to

Air Filter Maintenance.

Adjust Idle Speed Screw

WARNING: The cutting attachment may be

spinning during idle speed adjustment. Wear

protective clothing and observe all safety

instructions to prevent serious personal

injury.
