Traction Controls Important: The traction control pedal, the utility-traction lever, and the attachment control lever must be in the Neutral position before you can start the engine. Important: You must sit in the operator seat to move the traction controls from the Neutral position and move the machine; otherwise, the engine will stop in 1 second. Note: Operation of the traction control pedal overrides operation of the utility-traction lever.
Transmission Range Switch • Pull the joystick back to raise the blade. The transmission range switch (Figure 13) is used to control the gear reduction range of the transmission, and it has 2 positions (high and low). • Push the joystick to the right (away from you) to swing the blade to the right. • Pull the joystick to the left (toward you) to swing the blade to the left. Important: Do not shift between the transmission ranges while the machine is moving.

Fast forward chain speed 4. Slow reverse chain speed or slow plow vibration 2. Slow forward chain speed 5. Fast reverse chain speed or fast plow vibration The seat interlock system requires the operator to sit in the operator seat while operating this machine.
Specifications Seat Belt Note: Specifications and design are subject to change without notice. WARNING Operating the machine without the rollover protection system (ROPS) securely in place can result in serious injury or death if the machine rolls over. Basic Machine Dimensions and Weight Data • Ensure that the roll bar is securely in place. • Always wear a seat belt with the ROPS in place. • Ensure that the operator seat is properly secured to the machine.
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 Note: Remove the cap slowly to reduce the air pressure buildup. 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 must meet specification ASTM D6751 or EN14214. • The blended fuel composition should meet ASTM D975 or EN590. • Biodiesel blends may be damage painted surfaces.
High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46 (cont'd.) Pour Point, ASTM D97 -37°C (-34°F) to -45°C (-49°F) 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.
Note: If the machine is equipped with a backhoe, ensure that the engine shutoff control is pulled up. 4. If the hydraulic fluid level is below the Add mark, remove the fill cap (Figure 21), add the specified hydraulic fluid to raise the fluid level up to the Full mark, and install the fill cap. 6. Pull the throttle lever out to the 1/2 Throttle position. Note: In extreme hot or cold weather, take the necessary precautions; refer to Operating the Machine in Extreme Conditions (page 26).
Breaking in a New or Rebuilt Engine • To increase the engine speed, push the throttle center button while pulling out the throttle (Figure 22). 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 25) 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 26 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 28 • 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 28).
Completing the Work for the Day If you must tow the machine, perform the following steps using caution: 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. When you complete your work for the day, do the following: 1. Backfill the spoils in the part(s) of the trench in which you are finished working. 2.
