GEAR 9V9104 - Caterpillar

Be sure no one is working on or near the machine to prevent injury. Keep the machine under control at all times to prevent injury.Reduce engine speed when maneuvering in tight quarters or when breaking over a rise.Select the gear speed necessary before starting downgrade. Do not change gears while going downhill.A good practice is to use the same gear speed going downgrade that would be used to go up the grade.Do not allow the engine to overspeed downhill. Use the service brake pedal to reduce engine overspeed going downhill.When the load will be pushing the machine, put the transmission selector lever in FIRST speed before starting downhill.1. Adjust the operator's seat.2. Fasten the seat belt.3. Raise all lowered attachments enough to clear any obstructions.4. Push down on the service brake pedal to keep the machine from moving. 5. Push the button on the parking brake lever and lower the lever to release the parking brake. 6. Press the left side of the switch to release the transmission neutral lock.7. Move the transmission control lever to the desired direction and gear speed.8. Release the service brake pedal.9. Push down on the accelerator pedal to the desired engine speed.10. Drive the machine forward for best visibility and control.
For operator comfort and maximum service life of power train components, deceleration and/or braking is recommended before any directional shifts are made.
Parking Brake System
Personal injury could result from the sudden stop of the machine. The parking brake is automatically engaged when brake oil pressure drops below an adequate operating pressure.If the brake system oil pressure drops below normal operating pressure, an action alarm will sound and the parking brake alert indicators on the operator's panel will flash. The action light will start flashing.If the pressure drops farther, the parking brake will engage automatically.Be prepared for a sudden stop. Correct the reason for the loss of oil pressure. Do not move the machine without normal brake oil pressure.
Loss of brake oil pressure will cause the brake alert indicators on the operator panel to flash. Loss of oil pressure will cause the parking brake to automatically engage and stop the machine.The action light will also flash when the monitor system lights flash.
Moving the machine with the parking brake engaged can cause excessive wear or damage to the brake. If necessary, have the brake repaired before operating the machine.
Supplemental Steering (If Equipped)
If the primary steering alert indicator flashes, steer the machine immediately to an out-of-the-way location and stop.Have any necessary repairs made before returning the machine to operation.Steering and braking effort will increase with the engine stopped.Supplemental steering works only while the machine is in motion. The primary steering alert indicator indicates the primary steering has failed and supplemental steering is in use. When the alert indicator flashes, steer the machine immediately to an out-of-the-way location and stop the machine. Stop the engine and investigate the cause. Do not operate the machine until the cause has been found and corrected.
