Hour Meter Product Overview The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance (Figure 6). Fuel Gauge The fuel gauge is located with the hour meter, and the bars light up when the ignition switch is in the On position (Figure 6). The indicator light appears when the fuel level is low (approximately one gallon remaining in the fuel tank).
Choke Neutral-Lock Position Use the choke to start a cold engine. Pull the choke knob up to engage it. The neutral-lock position is used with the safety-interlock system to engage and to determine the neutral position. Blade-Control Switch (PTO) Fuel Shutoff Valve The blade-control switch (PTO) is used to engage the electric clutch and drive the mower blades. Pull the switch up to engage the blades and release.
Operation DANGER 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. • Always place gasoline containers on the ground away from your vehicle before filling.
Add the correct amount of gas stabilizer/conditioner to the gas. 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. Filling the Fuel Tank g029938 Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand. 1. Park the machine on level ground. 2.
