OPERATIONAL INFORMATION 0005
Machine Operation – Transmission, Speed, and Steering Control 0005
WARNING
• To prevent injury, make sure that no maintenance work is being performed on or near machine.
• Keep machine under control at all times in order to prevent injury. Reduce engine speed when you maneuver in tight quarters or when you break over a rise.
• Select gear range that is appropriate before you start downhill. Do not change gears when you are going downhill. Do not allow engine to overspeed when you are unloaded and moving down a slope. Watch tachometer and use service brakes. Use service brakes near the top of slope to prevent excessive engine speed.
• When you drive down a grade, use same gear used when driving up the grade.
• Machine will turn (counter-rotate) when transmission is in NEUTRAL, parking brake is disengaged, and left joystick (steering lever) is pushed forward or pulled rearward.
• Ensure all personnel are clear of machine before disengaging parking brake.
• Engage parking brake to lock left joystick and prevent machine movement.
• Do not allow riders on machine.
• If machine begins to sideslip, discard load and turn machine downhill.
• Whenever possible, operate machine up and down slopes, not across slope.
• Failure to follow these warnings may result in injury or death to personnel.
WARNING
Always use a ground guide when moving machine up or down a ramp when loading/
unloading. Failure to use a ground guide may result in an accident, causing death or injury to personnel or damage to equipment.
1. After engine is warmed up, raise bulldozer blade and ripper to clear any unexpected obstacles (WP 0004).
2. Hold service brake pedal down and disengage parking brakes (WP 0004).
NOTE
When parking brake is engaged, transmission defaults to neutral. When parking brake is disengaged, transmission will stay in neutral until desired direction and gear are selected.
