Ignition Switch Length: This switch is used to start the mower engine and has three positions: Start, Run and Off. Motion-Control Levers The motion-control levers are used to drive the machine forward, reverse, and turn either direction. The neutral-lock position is used with the safety-interlock system to engage and to determine neutral position. Close the fuel-shutoff valve (under the seat) when transporting or storing the mower.
Operation DANGER In certain conditions during fueling, static electricity can cause a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • Always place gasoline containers on the ground away from your vehicle before filling.
Breaking in a New Machine Filling the Fuel Tank 1. Park the machine on level ground. 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. 2. Shut the engine off and set the parking brake. 3. Clean around the fuel-tank cap and remove it.
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 fully 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 operator’s 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.
