Choke Length: 60 inch Deck Use the choke to start a cold engine. Pull the choke knob up to engage it. Blade-Control Switch (PTO) 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. Neutral-Lock Position The neutral-lock position is used with the safety-interlock system to engage and to determine neutral position.
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. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck-bed liners may insulate the container and slow the loss of any static charge.
Filling the Fuel Tank chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 1. Park the machine on level ground. 2. Shut the engine off and set the parking brake. 3. Clean around the fuel-tank cap and remove it. Add regular unleaded gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This space in the tank allows the gasoline to expand. Do not fill the fuel tank completely full; refer to (Figure 7).
Checking the Engine-Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level (page 41). Breaking in a New Machine 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.
g029797 Figure 9 g000963 Figure 10 1. Mower deck 1. Safe Zone—use the Z Master here on slopes less than 15 degrees or flat areas. 2. Danger Zone—use a walk-behind mower and/or a hand trimmer on slopes greater than 15 degrees and near drop-offs and water.
