Hydraulic Lockout Control (1)
The lever for the hydraulic lockout control is located at the left side of the left console.
Locked - Move the travel levers/pedals and move the joysticks to the HOLD (center) position. Move the lever for the hydraulic lockout control backward to the LOCKED position. This makes all of the factory installed hydraulic controls inoperable. |
Note: Make sure that the lever for the hydraulic lockout control is in the LOCKED position before attempting to start the engine. If the lever is in the UNLOCKED position, the engine start switch will not function.
Unlocked - Move the lever for the hydraulic lockout control forward to the UNLOCKED position. This makes all of the factory installed hydraulic controls operable. |

Increase - Turn the engine speed dial clockwise in order to increase the engine speed (engine rpm). |
Backup Method for Controlling Engine Speed
If the control system does not work due to a malfunction and the engine speed cannot be adjusted by the engine speed dial, the following method will allow you to adjust the engine speed temporarily. Make repairs as soon as possible.
Check the message display for any error messages. If the error message "ECM ERROR" is displayed, there is a problem in the electronic controller. See "Backup Controls (if equipped)".
If the engine speed cannot be adjusted by the engine speed dial and the indicator for the electronic controller does not come on, see "Backup Controls (if equipped)".
Note: Even if you cannot control the engine speed, you can turn the engine on and off with the engine start switch.
Engine Start Switch (7)
NOTICE |
---|
The engine start switch must be in the ON position and the engine must be running in order to maintain electrical functions and hydraulic functions. This procedure must be followed in order to prevent serious machine damage. |
OFF - Insert the engine start switch key only while the start switch is in the OFF position. Remove the engine start switch key only while the engine start switch is in the OFF position. Turn the engine start switch to the OFF position before you attempt to restart the engine. Turn the engine start switch to the OFF position in order to stop the engine. |
ON - Turn the engine start switch clockwise to the ON position in order to activate all cab circuits. |
START - Turn the engine start switch clockwise to the START position in order to crank the engine. Release the engine start switch key after the engine starts. The start switch will return to the ON position. |
Note: If the engine does not start after 30 seconds, return the engine start switch to the OFF position. Wait for 2 minutes before you return the engine start switch to the START position .
To start the engine, the battery disconnect switch must be on and the hydraulic lockout control must be in the locked position. For details, see the Operation and Main10ance Manual, "Engine Starting".

Backup Controls (if equipped) (11)
The backup switches are located under the right armrest.
Illustration 12 | g01161702 |
Engine Speed Control - By utilizing these switches, the engine speed can be controlled manually by the operator or the engine speed can be controlled automatically by the electronic controller. |
Automatic - When the electronic control system is functioning properly, backup switch (28) should be in this position. |
Manual - If a problem occurs in the electronic control system, move backup switch (28) to this position in order to disconnect the controller circuit of the electronic controller system. In this condition, the machine can be operated at a reduced ratio of pump output on a temporary basis. "BACK UP SWITCH ON" will appear on the message display. |
Fast Engine Speed - Move backup switch (29) to this position in order to increase the engine speed. This backup switch will not operate if backup switch (28) is not in the MANUAL position. When the switch is released the switch returns to the NEUTRAL position and the machine will maintain the engine speed. This switch overrides the function of the engine speed dial. |
Slow Engine Speed - Move backup switch (29) to this position in order to decrease the engine speed. This backup switch will not operate if backup switch (28) is not in the MANUAL position. When the switch is released the switch returns to the NEUTRAL position and the machine will maintain the engine speed. This switch overrides the function of the engine speed dial. |
Travel Speed Control (12)
Do not change the setting of the travel speed control switch while you travel. Machine stability may be adversely affected. Personal injury can result from sudden changes in machine stability. |
Travel Speed Control Switch - Press the travel speed control switch in order to select automatic travel speed or low travel speed. When the engine start switch is on, the travel speed control switch is always set at the LOW SPEED position. Whenever the travel speed control switch is pressed, the travel speed changes. |
Low Speed - Select the LOW SPEED position if you travel on rough surfaces or on soft surfaces or if you require a great drawbar pull. Also, select the LOW SPEED position if you are loading a machine onto a trailer or you are unloading a machine from a trailer. |
Automatic - If you travel on a hard, level surface at a fast speed, select the AUTO position. |
Continuous driving at high speed should be limited to 2 hours. If you need to continue driving at high speed for more than 2 hours, stop the machine for 10 minutes. This will cool down the travel drives before you resume driving.
Automatic Engine Speed Control (13)
The Automatic Engine Speed Control (AEC) automatically reduces engine speed when the machine is inactive. The AEC system is designed to reduce fuel consumption and noise. Lower engine speeds can also increase engine life.
The AEC system will be inoperable while the backup switch of the electronic controller system is in the MAN position.
The engine rpm will recover automatically to the setting of the engine speed dial when any hydraulic function is activated. The AEC system operates in 3 modes. Refer to Table 1 for a description of each mode.
Automatic Engine Speed Control (AEC) - The Automatic Engine Speed Control switch is activated when the engine start switch is turned to the ON position. The indicator lamp will turn on. When you press the AEC switch, the function of the AEC switch changes from ON to OFF, and vice versa. The operator can choose from 3 possible modes for automatic engine speed control. Refer to Table 1 for more details. |
Illustration 13 | g01077282 |
The switch for manual low idle is on the right joystick.
Manual Low Idle - Activate the manual low idle in order to reduce the engine speed to approximately 1020 rpm. Pressing the switch again will allow the engine speed to return to the original setting of the engine speed dial.
The manual low idle allows the operator to easily reduce the rpm without touching the engine speed dial. This is useful when the operator wants to reduce the engine speed in order to talk to someone or while the operator is waiting for a truck.
Operation of the automatic engine speed control depends on the position of the AEC switch and of the switch for manual low idle. The engine rpm will recover automatically to the setting of the engine speed dial when any hydraulic function is activated.
AEC Mode     | Position of AEC Switch     | Setting of Engine Speed Dial     | Position of Manual Low Idle Switch     | Description of Mode     |
First stage     | OFF     | 5 to 10     | OFF     | The electronic controller automatically reduces engine speed by 100 rpm after there has been no hydraulic demand for approximately 3 seconds.     |
Second stage     | ON     | 5 to 10     | OFF     | The AEC system in the electronic controller will automatically reduce the engine rpm to approximately 1300 rpm after there has been no hydraulic demand for approximately 3 seconds.     |
Manual low Idle     | ON or OFF     | 3 to 10     | ON     | The engine speed is reduced to approximately 1020 rpm.     |
Travel Alarm Cancel Switch (14)
