RECOMMENDED OIL TYPE

_crankcase

Using the proper type and weight of oil in the 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 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 100 ml (3.4 oz,) bottle of SAE 30 SF, SG, SH oil (Fig. 17).

NOTE: Save the bottle to measure the correct amount for future oil changes, See Changing the Oil

Pg. 21.

NOTE: Your new 4-Cycle trimmer is shipped for operation in conditions above 4°C (40°F). For cold weather operation, temperatures below 4°C (40°F) use a high-quality SAE 10W30 weight oil of API

(American Petroleum Institute) service class SF,

SG, SH.

RECOMMENDED FUEL TYPE

Old fuel is the primarj reason for the unit not running properly. Be sure to use fresh, clean, unleaded Petrol (gasoline).

NOTE: This is a four cycle engine. In order to avoic_ damage to the unit, do not mix oil with Petrol

(gasoline).

Definition of Blended Fuels

Today's fuels are often a blend of petrol [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 (leas 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 petrol (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 _armful deposits in the carburetor for up to six (6) months. Add 23 ml

(0.8 oz.) of fuel additive per gallon of fuel according to the instructions on the container. NEVER add fuel additives directly to the unit's petrol (gasoline) tank.

FUELING UNIT

WARNING:

Petrol (gasoline) is extremely flammable and its vapors can explode if ignited. To avoid serious personal injury, always stop the engine and allow it to cool before filling the fuel tank. Do not smoke whilst filling the tank. Keep sparks and open flames away from the area.

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. 28) whilst operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended.

Line release becomes more difficult as cutting ine becomes shorter

Each time the head is bumped, about 25.4 mm (1 inch) of trimming line is released. A blade in the cutting attachment guard will cut the line 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 in tall grass, the engine may stall. Always keep the tdmming 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 whilst the unit is running.

CAUTION:

Do not remove or a ter the line cutting blade assembly.

Excessive line length will make the clutch overheat.

This may lead

to serious personal injury or damage to the unit.

Some line breakage wiU 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

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 200 mm (8 inches) 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 a forwardbackward or side-to-side motion. Cutting shorter lengths produces the best results.

• Tdm 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 wall as opposed to trimming around a tree.

Fig, 28

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing al!

vegetation around trees; posts, fences, etc.

Rotate the whole unit so that the Cutting attachment is at a 30 ° angle to the ground (Fig. 29).

WARNING:

Do not use the cutting blade for to yourself or others can occur.

Before operating the unit with the cutting blade stand in the operating position (Figs. 30). Refer to Holding the

Trimmer, Pg. 17.

Cutting Blade Operating Tips:

To establish a rhythmic cutting procedure:

• Plant feet firmly, comfortably apart.

• Bring the engine to full throttle before entering the matedal to be cut. The blade has maximum cutting power at full throttle and is less likely to bind, stall, or cause kick back, which can result in serious personal injury to the operator or others.

i_k,

ARNING:

Kick back may occur when the does not immediately cut. Kick back can be violent enough to cause the unit and/or operator to be propelled in any direction, and possibly lose control of the unit. Kick back can occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut.

Cut whilst swinging the upper part of your body from right to left.

• Always release the throttle trigger and allow the engine to return to idle speed when not cutting.

• When done always unsnap unit from harness before taking harness off.

I_hl

the engine is turned off, The coasting blade

WARNING:

The blade continues to spin after] can seriously cut you if accidentally touched.

• Swing the unit in the same direction as the blade spins, which increases the cutting action.

* Move forward to the next area to be cut after the return swing and plant feet again.

• The cutting blade is designed with a second cutting edge, which can be used by removing the blade, turning it upside down, and reinstalling it.

WARNING:

Do not sharpen the cuffing blade. Sharpening the blade can cause the

blade tip to break off whilst in use. This can

result in severe personal injury to yourself

others. Replace the blade.

To reduce the chance of material wrapping around the blade, follow these steps:

Cut at full throttle.

g Swing the unit into material to be cut from your right to your left (Fig. 31).

• Avoid the material just cut as you make the return swing.

WARNING:

Do not clear away cut material

with the engine running or blade turning.
