They are flammable • and vapors are explosive. – Use only an approved container.
Slope Operation • Do not touch parts that may be hot from operation. Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. • Avoid operating this machine on slopes, if possible. • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction. • Avoid starting or stopping the machine on a slope.
Communication Line Safety • Keep your body and hands away from pin hole leaks or nozzles that eject high-pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks; never use your hands. Hydraulic fluid escaping under pressure can penetrate skin and cause injury, requiring surgery within a few hours by a qualified surgeon; otherwise, gangrene may result. CAUTION If you damage the fiber-optic cable and look into the exposed highly-intense light, you may harm your eyes.

Operation cold flow characteristics, which aid in starting the engine and help prevent clogging the fuel filter. Note: Determine the left and right sides of the machine from the normal operating position. Using summer-grade fuel above 20° F (-7°C) contributes toward a longer fuel pump life and increased power compared to using winter-grade fuel.
Using Biodiesel Fuel 2. Fill the fuel tank to the bottom of the neck to allow the fuel room to expand. 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: Note: The fuel tank capacity is 75.7 L (20 US gal). 3. Install the fuel tank cap and tighten it securely by hand.
High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46 (cont'd.) 11 or better FZG, Fail stage Water content (new fluid) Industry Specifications: Vickers I-286-S (Quality Level), Vickers M-2950-S (Quality Level), Denison HF-0 Note: Many brands of hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (0.68 oz) bottles. One bottle is sufficient for 15.1 to 22.7 L (4.0 to 6.0 US gal) of hydraulic oil.
Note: If the machine is equipped with a backhoe, ensure that the engine shutoff control is pulled up. specified hydraulic fluid to raise the fluid level up to the Full mark, and install the fill cap/breather. 6. Pull the throttle lever out to the 1/2 Throttle position.

Breaking in a New or Rebuilt Engine • To increase the engine speed, push the throttle center button while pulling out the throttle (Figure 24). During the first 20 hours of operation of a new or rebuilt engine, do the following: • Keep the engine at a normal operating temperature. • Do not run the engine at low idle speeds for long periods of time. • Operate the machine with normal loads for the first 8 hours. • Do not use special “break-in” lubricating oil.
Driving and Stopping the Machine 2. The machine comes with a maintenance-free battery. If you use a different battery and add water to it when the temperature is below 0ºC (32ºF), ensure that you charge the battery or run the engine for about 2 hours to prevent the battery from freezing. Using the Traction Control Pedal 3. Inspect the battery cables and terminals. Clean the terminals, and apply a coat of grease on each terminal to prevent corrosion.
Operating the Transmission Note: Move the lever completely forward or rearward for the maximum speed. 3. Release the lever. Operating the Drive Mode Switch Note: The lever is held in place front-to-rear by friction in order to maintain a constant speed. This toggle switch (Figure 27) controls the mode for the hydraulic motor and has 2 positions: Transport and Work. Select the desired operating position.
• Ensure that the ROPS and the seat belt are properly installed and in good working order. • Ensure that all instruments, the controls-in-neutral light, and the all warning lights are working properly. • Ensure that all controls are working properly in a clear, open area. Note: The controls-in-neutral light will turn on when the key switch is in the On position and the utility-traction lever is in the Neutral position. 1. Warm up the engine. Figure 28 1. Low range 2.
To operate the backfill blade, do the following: • To raise the backfill blade: Move the joystick rearward. • To lower the backfill blade: Move the joystick partially forward. • To angle the backfill blade to the right: Move the joystick G023080 to the right. Figure 30 • To angle the backfill blade to the left: Move the joystick to the left. 10. Fasten the rear of the machine to the trailer using chains and a binder (Figure 30).
Note: If you do not have a rigid drawbar, use 2 towing machines. Attach a tow chain each to the front and rear towing machines. Use the front towing machine to move the non-functioning machine and the rear towing machine to stop the non-functioning machine. 6. Disconnect the hand pump and connect the hose to the parking brake cylinder before transporting or making any repairs. Note: This machine has hydrostatic braking. When you stop the engine, the brakes automatically engage. 1.
