Ignition Switch Product Overview The ignition switch has 3 positions: OFF, RUN, and START. The key turns to START and moves back to RUN upon release. Turning the key to the OFF position stops the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine (Figure 5). Throttle Control The throttle controls the engine speed and it has a continuous variable setting from the SLOW to FAST position (Figure 5).
Operation G014521 Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • Ethanol: Gasoline with up to 10% ethanol (gasohol) 1 or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
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. DANGER In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.
Think Safety First CAUTION This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. Wear hearing protection when operating this machine. DANGER Operating the machine on wet grass or steep slopes can cause sliding and loss of control.
Testing the Safety-Interlock System Starting the Engine Note: A warm or hot engine may not require choking. Important: Do not engage the starter for more than 5 seconds at a time.
