REGULATOR AS-VOLTAGE 5137389 - Caterpillar

Be sure no one is working on or near the machine. Keep the machine under control at all times. Keep the machine as low as possible.
The rear elevation of the machine should be in the fully raised or "service height" position only for servicing the machine. The rear elevation must be lowered from the fully raised or "service height" position prior to operation of other machine functions. Failure to do so could result in loss of traction or an abrupt lateral tilt of the machine. If either of these conditions are experienced, lower the rear of the machine to allow the machine weight to be evenly distributed on all tracks. When the machine is not being serviced, keep the machine as low as possible.
1. Start the engine.2. Raise the mainframe so the rotor and moldboard will clear any obstructions.3. Select the desired mode of steering. 4. Adjust engine throttle switch (1) to high idle (highest engine speed).5. Sound horn (2) for several seconds to alert nearby personnel.6. Release parking brake (3).7. Move propel direction switch (4) to the desired direction.8. Select the desired travel speed with high/low travel speed selector switch (5) (HIGH or LOW).9. Move propel lever (6) to get the desired travel speed.Use propel lever (6) to reduce travel speed and to reduce the risk of "overspeeding" the engine going downhill.10. Drive the machine forward for best visibility and control.
Stay near a machine/engine remote stop switch. The switch must be instantly depressed to prevent a "runaway" if the track pump charge pressure falls below the required limit for control of the track pump.Avoid steep grades.Personal injury could result from the sudden stop of the machine.Be prepared for a sudden stop. Correct the reason for the loss of pressure. Do not move the machine without normal track pump charge pressure.
Speed and Direction Changes
1. Pull propel lever (2) completely back.2. Disengage the parking brake [parking brake knob (1) pulled out], if it is engaged.3. Move forward/reverse selector switch (3) momentarily to "F" to select movement in the forward direction. Move the forward/reverse selector switch momentarily to "R" to select movement in the reverse direction. The CMS display will indicate the direction of travel and when reverse is selected, the backup alarm will sound.
Be sure to raise the rotor to clear all obstacles when the rotor is running. Rotor damage can result if obstacles are struck with the rotor running while in the reverse direction. Sudden machine movement is also possible.
Parking Brake System
Personal injury could result from the sudden stop of the machine. Do not apply the parking brake before all machine movement is stopped.
The parking brake is used to prevent machine movement. Apply the parking brake before the engine is shut down. Apply the parking brake before starting the engine. The engine will start when the parking brake is not applied and machine movement is possible.Elevation Control
The electronic elevation control system provides both manual and automatic elevation control modes. Sonic sensors at either side of the machine can
