HANDLING THE FUEL

DANGER

The fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury may result.

■ Mix and store in a container approved for storing fuel.
■ DO NOT smoke when handling or close to fuel.
■ DO NOT allow flames or sparks near the fuel.
■ Maintain the pressure in the fuel tank; always loosen the fuel tank cap slowly allowing the pressure to equalize. NEVER refuel a trimmer when the engine is HOT or RUNNING!
■ DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
■ DO NOT overfill the fuel tank and clean up spills immediately.
- Securely tighten the fuel tank cap and close the fuel container after refueling.
■ Check for fuel leakages. If a fuel leakage is present, remove the battery and do not use the

trimmer until the leakage is repaired.

■ Move at least 10 ft (3 m) from refueling location before starting the engine.

FUEL MIXTURE (See Fig. 21)

This trimmer is powered by a 2-cycle engine; the operator is required to use premixed gasoline and 2-cycle lubricant. Prepare a mixture of unleaded gasoline and 2-cycle engine lubricant in a clean container approved for storing gasoline. Only prepare quantities that can be used up within a few days. DO NOT prepare quantities that will need to be stored for more than 30 days.

Recommended Fuel

This engine is certified to operate on unleaded gasoline intended for automotive use.

U.S. EPA regulations make it illegal to use gasoline containing higher than 10% ethanol content in outdoor power equipment like your LawnMaster ^® power equipment and doing so can void your LawnMaster ^® Limited Warranty.

If the proper precautions are taken, however, gasoline containing a 10% quantity of ethanol can safely be used in your LawnMaster ^® products.

Much of the gasoline sold throughout the United States contains ethanol. The maximum ethanol content allowed by law for use in outdoor power equipment is limited to 10% (E10). Most small power equipment engines are designed to use no more than a 10% ethanol gasoline blend.

If you are not sure of the ethanol content in the gasoline you are purchasing, ask the retailer. If they are unsure, purchase your fuel from another retailer that offers gasoline with no more than 10% ethanol.

NOTE: We recommend you use a high-quality synthetic 2-cycle lubricant in this product.

Recommended specification: JASO-FC or above. Mix at 40:1 ratio or 3.2 oz. per gallon (US).

Do not use automotive lubricant or 2-cycle outboard lubricant.

Gasoline to Lubricant Mix - 40 : 1 Ratio
	GASOLINE LUBRICANT
	1.0 gal. (US) (3.8 liter) 3.	2 oz. (95 ml)
	2.5 gal. (US) (9.5 liter) 8.	0 oz. (236 ml)

Mixing Tips

■ Always start by filling an approved fuel container with half of the required amount of gasoline.
■ Then add the entire amount of 2-cycle lubricant. Close the container and shake to mix the lubricant with the gasoline.
■ Add the remaining amount of gasoline, close the fuel container, and shake again.
■ Ensure that the fuel is well mixed by shaking the container before filling the fuel tank (Fig. 21).

WRONG Fig. 21

FILLING THE FUEL TANK (See Fig. 22)

NOTICE: Before each use, ALWAYS shake the fuel container thoroughly to ensure that the fuel is mixed completely.

■ Place the tool on a flat, level surface, outdoors. Ensure the fuel tank and the shaft are in the same level so enough fuel can be filled into the fuel tank.
■ Clean the area around the fuel tank and cap to prevent any contamination.
■ Loosen the fuel tank cap by turning it counter-clockwise and remove (Fig. 22).

Gasket Fig. 22

■ Carefully pour the fuel into the fuel tank, avoiding any spillage. Clean and check the gasket before replacing the cap onto the fuel tank.
■ DO NOT leave the fuel tank unsealed while it contains fuel. Replace the cap immediately after filling and inspecting the tank. Check that the cap is sealed tightly and wipe clean any spillage that may have occurred.

NOTICE: It is normal for smoke to be emitted from a new engine after first use.

WARNING

The operation of this tool requires gasoline, an extremely flammable liquid. Always turn off the engine and allow it to cool completely before fueling. Never remove the fuel tank cap or add the fuel to the tool while it is running or the engine is still hot. Make sure to fuel the tool outdoors on a flat, level surface. After fueling, immediately replace the fuel tank cap and tighten it securely. DO NOT fill the fuel tank on the work site; fueling must occur at least 10 ft. (3m) from where the operator intends to start the engine. Keep the tool away from smoke, open flames and sparks! Failure to follow these instructions could result in an explosion, fire and cause serious personal injury.

TRIMMING (See Fig. 33)

WARNING

The engine housing can become hot when the trimmer is being used. Do not make contact with this part of the tool during use and whilst it is still hot. When holding the trimmer, ensure all body parts are clear of the engine housing. Contact with this part can result in burns or other serious injuries.

WARNING

Always position the trimmer on your right side in order to reduce exposure to hot surfaces which can cause possible serious injuries.

WARNING

Keep the bottom of the engine below waist level during operation to avoid burns from hot surfaces.

■ Hold the grass trimmer firmly with both hands, keeping your right hand on the main handle and left hand on the assist handle.
■ The trimmer should be held at a comfortable position with the rear handle at waist level. If using the shoulder strap (sold separately), put on the shoulder strap and refer to the Installing the Shoulder Strap section (Fig. 33).

■ Keep your balance with your feet apart.
■ Always operate the trimmer in RUN position. When cutting long grass, work in stages from top to bottom in small sections. This will prevent the grass being cut from wrapping around the shaft and the spool head.
■ Hold the grass trimmer head at an angle of approximately 30^ to the ground. Avoid pressing it against the ground as this can ruin the lawn and damage the product.
■ Stop the engine if the grass becomes wrapped around the trimmer head and remove the grass once the cutting attachment has stopped rotating.
■ Extended use of the tool at partial throttle will result in lubricant dripping from the muffler.

TRIMMING TIPS (See Figs. 33-34)

• Keep the tool to the right side and away from your body to avoid making contact with the hot surfaces (Fig. 33).
• Keep the trimmer head lowered, towards the area being cut.
  ■ The straight shaft trimmer cuts best when moving the unit from left to right. Passing the tool in this direction will reduce the amount of debris thrown towards the operator. Avoid cutting in the dangerous area as shown (Fig. 34).
  ■ Use the tip of line to do the cutting; do not force the trimmer head into uncut grass.
  ■ The line can wear quickly and even break when used against solid surfaces such as fences, borders, curbs and walls made of metal, wood, stone and brick. Avoid using the trimmer against these materials.

ADVANCING LINE (See Fig. 35)

This trimmer uses a line advance system which requires the operator to tap or bump the trimmer head on the grass while running the engine at full throttle.

■ Run the engine at full throttle.
■ Tap the trimmer head on the ground to advance the line. With each tap, the line advances further. A firm but gentle motion should be used when tapping the line on the ground (Fig. 35). DO NOT keep the trimmer head pressed against the ground.

NOTICE: The cutting blade on the underside of the debris guard will cut the line to the correct length.

NOTICE: Line that is too short may not advance using the tapping method and may need to be done manually.

To advance the cutting line manually:

■ Stop the engine completely.
■ Push the spool cover in while pulling on the line, until you reach the desired length.

NOTE: After each use, clean the trimmer head with a damp cloth to remove dirt and grime.

CUTTING BLADE (See Fig. 36)

The trimmer line cutting blade is attached to the underside of the debris guard (Fig. 36).

The cutting blade trims the line at a length that yields optimum cutting results. If the engine is running faster than normal, or it appears as though the trimmer is less efficient, advance the line. This will maintain proper performance and keep the line long enough to efficiently cut the grass.
