Safety-Interlock Indicators If the system detects a problem or fault, the malfunction indicator light (MIL) illuminates. There are symbols on the hour meter indicate with a black triangle that the interlock component is in the correct position (Figure 6). The MIL is the red light located in the right console panel. Battery Indicator Light If the MIL illuminates, perform the initial troubleshooting checks; refer to the MIL section in Troubleshooting (page 72).
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 extra 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 40). 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.
