For simplicity and best engine performance, mix 8 ounces (250 ml) of Lawn-Boy Generation II, 2-Cycle Ashless Oil with two gallons (8 liters) of fresh, unleaded regular gasoline. Pour one gallon (4 liters) of gasoline into an approved gasoline container and add the correct amount of 2-cycle oil. Install cap on gasoline container and shake to mix oil and gasoline thoroughly (Fig. 4). Slowly remove the cap and add the remaining gasoline.

Use clean, fresh lead-free gasoline with an octane rating

The equipment engine must be free from defects in materials and workmanship which cause it to fail to conform with U.S. EPA standards for the first two years of engine use from the date of sale to the ultimate purchaser. Lawn-Boy must warrant the emission control system on your utility/lawn/garden equipment engine for the period of time listed above provided there has been no abuse, neglect or improper maintenance of your utility/lawn/garden equipment engine.

Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and catalytic converter. Also included may be hoses, belts, and connectors and other emission related assemblies.

Where a warrantable condition exists, Lawn-Boy will repair your engine at no cost to you including diagnosis, parts and labor.
