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 Specifications Use the choke to start a cold engine. Pull the choke knob up to engage it. Note: Specifications and design are subject to change without notice. Width Blade-Control Switch (PTO) Use 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.
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 18). 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.
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 the machine on wet grass or steep slopes can cause sliding and loss of control. • Do not operate on slopes greater than 15 degrees. • Reduce speed and use extreme caution on slopes. g000963 Figure 9 • Do not operate the machine near water. 1. Safe zone—use the machine here on slopes less than 15 degrees or flat areas. 2.
Setting the Parking Brake WARNING Parking brake may not hold machine parked on a slope and could cause personal injury or property damage.
