HANDLING THE FUEL


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 blower 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 blower until the leakage is repaired.
  • Move at least 10ft. (3m) from refueling location before starting the engine.

FUEL MIXTURE (See Fig. 15)

  • This blower 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.

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 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. 15).
    FUEL MIXTURE

FILLING THE FUEL TANK (See Fig. 16)
