Operation

The voltmeter measure the voltage output of the alternator. Both high and low voltages will potentially damage the battery.

Glow Plug Switch and Light

Located on the right fuel tank.

Depress and hold the switch to heat the glow plugs. The glow plug light comes on when the glow plug switch is depressed. The glow plug light indicates the glow plugs are preheating the combustion chamber.

Low Oil Pressure Light

Located on the right fuel tank.

Light will come on when engine oil pressure is low or lost.

Warning Buzzer

Located behind the seat under the air deflector on the electrical panel.

The buzzer is a warning signal that the engine is overheating or the oil pressure is low. See the Troubleshooting section.

Pre-Start

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.

Determining 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.

Use summer grade diesel fuel (No. 2-D) at temperatures above 20°F (-7°C) and winter grade diesel fuel (No. 1-D or No. 1-D/2-D blend) below 20° F (-7° C). Use of winter grade diesel fuel at lower temperatures provides lower flash point and pour point characteristics, therefore easing startability and lessening chances of chemical separation of the fuel due to lower temperatures (wax appearance, which may plug filters).

Use of summer grade diesel fuel above 20°F (-7°C) will contribute toward longer life of the pump components.

Important: Do Not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur.

Observe the following precautions:

The biodiesel portion of the fuel meet specification ASTM D6751 or EN14214.

The blended fuel composition should meet ASTM D975 or EN590.

Painted surfaces may be damaged by biodiesel blends.

Use B5 (biodiesel contend of 5%) or lesser blend in cold weather.

Monitor seals, hoses, gaskets in contact with fuel as they may be degrade over time.

Fuel filter plugging maybe expected for a time after converting to biodiesel blends.

Contact your distributor if you wish for more information on biodiesel.

Filling the Fuel Tank

1.Shut the engine off and set the parking brake.

2.Clean around each fuel tank cap and remove the cap. Add fuel to both fuel tanks, until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This space in the tank allows the fuel to expand. Do Not fill the fuel tanks completely full.

3.Install fuel tank caps securely. Wipe up any fuel that may have spilled.

4.If possible, fill the fuel tank after each use. This will minimize possible buildup of condensation inside the fuel tank.
