VALVE GP-CMB 4734647 - 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 range necessary before starting downgrade. Do not change gears while going downhill.A good practice is to use the same gear range 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 in the parking brake knob to release the parking brake.6. Disengage the transmission neutral lock (if equipped).7. Move the transmission control lever to the desired direction and 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 air pressure drops below safe operating pressure.If the brake system oil pressure drops below normal operating pressure, a warning horn will sound and the parking brake indicators on the operator's panel will come on. The fault light will start flashing.If the pressure drops further, the parking brake will engage automatically.Be prepared for a sudden stop. Correct the reason for the loss of air pressure. Do not move the machine without normal brake oil pressure.
Loss of brake air pressure will cause the low air pressure horn to sound. Loss of air pressure will cause the parking brake to automatically engage and stop the machine.
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)
Personal injury or death could result when primary steering fails.If the primary steering fault light comes on, steer the machine IMMEDIATELY to a safe 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 fault light indicates primary steering has failed and supplemental steering is in use. When the light comes on, steer the machine immediately to a safe location and stop. Stop the engine and investigate the cause. Do not operate the machine until the cause has been found and corrected.
