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).
Blade-Control Switch (PTO) Neutral-Lock Position 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. To disengage the blades, push the blade-control switch (PTO) down or move a motion-control lever into the neutral-lock position. The neutral-lock position is used with the safety-interlock system to engage and to determine the neutral position.
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.
Breaking in a New Machine of varnish deposits in the fuel system, use fuel stabilizer at all times. New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance. Filling the Fuel Tank Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck.
Think Safety First Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. DANGER Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. There is no rollover protection when the roll bar is down. Always keep the roll bar in the raised and locked position and use the seat belt.
Releasing the Parking Brake CAUTION This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. The use of protective equipment for eyes, ears, feet, and head is recommended. g027335 1 2 Figure 12 Operating the Mower Blade-Control Switch (PTO) G009027 Figure 10 1. Wear safety glasses 2.
