Product Overview Controls Become familiar with all the controls before you start the engine and operate the machine. Traction Pedal The traction pedal (Figure 6) controls the forward and reverse operation. Press the top of the pedal to move forward and the bottom to move rearward. Ground speed depends on how far you press the pedal. For no load, maximum ground speed, fully press the pedal while the throttle is in the Fast position. Figure 5 1. Roll bar 3. Hairpin cotter pin 2.
Parking Brake Throttle Lever To engage the parking brake, push down on the brake pedal and press the top forward to latch (Figure 6). To release the parking brake, press the brake pedal until the parking brake latch retracts without contacting the locking mechanism. The throttle lever (Figure 7) controls the speed of the engine. Moving the throttle lever forward toward the Fast position increases the engine speed. Moving it rearward toward the Slow position decreases the engine speed.
Charge Indicator Illuminates when the charging system circuit malfunctions (Figure 7). Oil Pressure Warning Light The oil pressure warning light (Figure 7) glows when the oil pressure in engine drops below a safe level. If low oil pressure ever occurs, stop the engine immediately and determine the cause. Repair the damage before starting the engine again. Fuel Gauge The fuel gauge (Figure 8) indicates the fuel level remaining in the fuel tank. Figure 9 1. Wind shield wiper/washer switch 2.
Operation Note: Determine the left and right sides of the machine from the normal operating position. CAUTION This machine produces sound levels in excess of 80 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Adding Fuel Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40.
• The blended fuel composition should meet ASTM D9751. DANGER • Use B5 (biodiesel content of 5%) or lesser blends in cold weather. 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. • Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time. • Always place fuel containers on the ground away from your vehicle before filling.
4. Add fuel to the fuel tank, until the level is even with the bottom of the filler neck. Do not over fill the fuel tank. 5. Install the fuel tank cap and secure.
