Gasoline and Oil Recommended Gasoline Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. POTENTIAL HAZARD • In certain conditions gasoline is extremely flammable and highly explosive. WHAT CAN HAPPEN IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.
Gasoline and Oil Stabilizer/Conditioner Filling the Fuel Tank Add the correct amount of gas stabilizer/conditioner to the gas. Using a stabilizer/conditioner in the machine: 1. Shut the engine off and set the parking brake. 2. Clean around each fuel tank cap and remove the cap. Add unleaded regular gasoline to both fuel tanks, until the level is 1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand.
Operation Think Safety First Parking Brake Please carefully read all the safety instructions and symbols in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. Always set the parking brake when you stop the machine or leave it unattended.
