INJURY. Check and maintain the proper oil level in the crank case; it is important and cannot be overemphasized, Check the oil before each use and change it as needed.

See Changing the Oil.

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 SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE

NOTE: This unit is shipped without oil. In order to avoid damage to the unit, put oil in the crankcase before you attempt to start the unit.

Your unit is supplied with one 3.4 fluid oz. (100 ml.) bottle of SAE 30 SF, SG, SH oil (Fig. 7).

NOTE: Save the bottle of oil. It can be used to measure the correct amount during future oil changes.

RECOMMENDED FUEL TYPE

Old fuel is the primary reason for improper unit performance.

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 fue! additive per gallon of fuel according to the instructions on the container.

NEVER add fuel additives directly to the unit's gas tank.

and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position

(Fig. 17). Check for the following:

The operator is wearing eye protection and proper clothing

With a slightly-bent right arm, the operator's hand is holding the shaft grip

The operator's left arm is straight, the left hand holding the J-handle

The unit is at waist level

The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend over

Fig. 17

ADJUSTING TRIMMING LINE LENGTH

The Bump Head

TM cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 18) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended.

Line release becomes more difficult when the cutting line gets shorter.

NOTE: Do not rest the Bump Head

TM while the unit is running.

on the ground

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 cutting blade assembly. Excessive line length

CAUTION: Do not remove or alter the line will make the clutch overheat. This may lead to serous persona njury or damage to the un t.

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 efficiency and may overload the engine.

Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

Cut from right to left whenever possible. Cutting to the left 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 a forwardbackward 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 trimming techniques

What vegetation is being cut

Where vegetation is cut

For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.

Rotate the whole unit so that the cutting attachment is at a 30 ° angle to the ground (Fig. 19).

Fig. 18

Each time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in the cutting attachment shield will cut the line to the proper length if any excess line is released.

For best results, tap the bump knob on bare ground or hard soil. if you attempt a line release in tall grass, the engine may stall. Always keep the trimming line fully extended.

Line release becomes more difficult when the cutting line gets shorter.

Drain and refill the tank with fresh fuel prior to making any adjustments.

Refer to Oil and Fuel

Information.

18

Clean Air Filter

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow. 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 during idle speed adjustments.

Wear

WARNING: The cutting attachment may spin instructions to prevent serious personal injury,

If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

1, Start the engine and let it run at a high idle for a minute to warm up. Refer to StaKJng/Stopping Instructions.

2.

Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips or flat blade screwdriver into the hole in the air filter/muffler cover (Fig. 40). Turn the idle speed screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

NOTE: The cutting attachment should not rotate when the engine idles.

3, If the cutting attachment rotates when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a time (as needed), to reduce idle speed.

Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems.

If not and all of the following are true:

• the engine will not idle

• the engine hesitates or stalls on acceleration

• there is a loss of engine power
