Engine Coolant Temperature Warning Light This light glows and the powered attachments will stop if the engine coolant temperature is high. But the engine will continue to run. If the machine is not stopped and the coolant temperature rises another 20° F, the engine will stop.
Fuel Gauge Operation The fuel gauge (Figure 7) indicates the quantity of fuel remaining in the fuel tanks. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel The engine runs on clean, fresh diesel fuel with a minimum octane rating of 40. Purchase fuel in quantities that can be used within 30 days to ensure fuel freshness. Combined tank capacity: 11.5 US gallons (43.5 l) Use summer grade diesel fuel (No.
• Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time. In certain conditions during fueling, static electricity can be released causing a spark which can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property. • Fuel filter plugging may be expected for a time after converting to biodiesel blended. • Contact your distributor if you wish for more information on biodiesel.
Operating on icy or steep slopes can cause sliding and loss of control. A track dropping over an edge can cause a rollover, which may result in serious injury, death, or drowning. Figure 8 Always use the seat belt. 1. Bottom of the filler neck Read and follow the rollover protection instructions and warnings. 5. Install the fuel tank caps securely. Wipe up any fuel that may have spilled. To avoid loss of control and possibility of rollover: Note: If possible, fill the fuel tanks after each use.
