OPERATION

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.

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 3.2 oz. per gallon (US). Do not use automotive lubricant or 2-cycle outboard lubricant.

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).
