OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

WARNING: It has been proven that fuel containing greater than 10% ethanol will likely damage this engine and void the warranty.

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. It forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 60 days old).

USING BLENDED FUELS

If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:

•Always use the fresh fuel mix explained in the operator's manual

•Always agitate the fuel mix before fueling the unit

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

USING FUEL ADDITIVES

CAUTION: For proper engine operation and maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

WARNING: Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 9). 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 D-handle
• The unit is at waist level
•	The cutting head is parallel to the ground and easily contacts the grass	Fig. 9
	without the need to bend over

WARNING: Do not remove or alter the line cutting blade assembly. Excessive line length will cause premature engine failure and / or unit damage.

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting head allows the release of trimming line without stopping the engine. To release more line, lightly tap the cutting head on the ground (Fig. 10)

while operating the unit at high speed.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

Each time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in the cutting head 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

attempting a line release in tall grass, the engine may stall. Always keep Fig. 10

the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter. NOTE: Do not rest the Bump Head™ on the ground while the unit is running.

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

TIPS FOR BEST TRIMMING RESULTS

•Keep the cutting head parallel to the ground.

•Do not force the cutting head. 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 unit into and out of the cutting area at the desired height. Move either in a 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 the cutting line is dependent upon:

• Following the trimming techniques

• What vegetation is being cut

• Where vegetation is cut Fig. 11

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, etc.. Rotate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 11).
