Controls or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Moving the control levers outward from the center position engages the parking brake and allows the operator to exit the machine (Figure 13). Always position the motion control levers into the brake position when you stop the machine or leave it unattended.
Recommended Gasoline Operation Use UNLEADED Regular Gasoline suitable for automotive use (87 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Note: Determine the left and right sides of the machine from the normal operating position. Think Safety First 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.
Add the correct amount of gas stabilizer/conditioner to the gas. In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.
