Command control steering | |
The direction for machines that are equipped with conventional steering is determined by the position of the lever that is located on the left side of the steering column. The direction for machines that are equipped with conventional steering and electrohydraulic controls is determined by the position of the lever that is located on the side of the steering column or by the Forward, Neutral, Reverse Switch that is located next to the implement controls.
The direction for machines that are equipped with command control steering is determined by the position of the switch that is located on the left side of the steering wheel.
(1) Forward
(2) Neutral
(3) Reverse
Forward/Neutral/Reverse Switch (If Equipped)
| |
| Illustration 13 | g01070945 |
Once the machine is started, the NEUTRAL lamp should be on. The machine may be placed into gear either by using the shifter or the forward/neutral/reverse switch. In order to use the shifter, ensure that the forward/neutral/reverse switch is in the NEUTRAL position. Use the shifter to select the direction. The appropriate direction indicator should illuminate.
In order to use the forward/neutral/reverse switch, place the shifter in the NEUTRAL position. Select the direction that is desired by using the forward/neutral/reverse switch. The appropriate direction indicator should illuminate.
The transmission will be placed in the NEUTRAL position if both the shifter and the forward/neutral/reverse switch indicate a state that is not the NEUTRAL position during operation. The neutral lamp will be OFF. Both the shifter and the forward/neutral/reverse switch must be placed in the NEUTRAL position before normal operation can resume.
The speed of the machine will be displayed on the front dash.

| |
| Illustration 17 | g00737672 |
|
|
OFF (1) - When you insert the engine start switch key and when you remove the engine start switch key, the engine start switch must be in the OFF position. To disconnect the power to the electrical circuits in the cab, turn the engine start switch to the OFF position. Also, turn the engine start switch to the OFF position in order to stop the engine. |
|
ON (2) - To activate the electrical circuits in the cab, turn the engine start switch key clockwise to the ON position. |
|

Note: If the engine fails to start, return the engine start switch to the OFF position. This must be done before you attempt to start the engine again.
Reference: Refer to Operation and Maintenance Manual, "Engine Starting" for more information on starting the engine.
Variable Shift Control (14) (If Equipped)
| |
| Illustration 18 | g00996477 |
The variable shift control is located on the switch panel. The variable shift control will change the transmission's characteristic of the shift points. The transmission can be set to shift sooner as the machine is accelerating. The transmission can be set to shift later as the machine is accelerating.
Rotate the switch clockwise into economy mode (3). The transmission will shift at a lower rpm. This position is the most fuel efficient position. This position will provide the most comfort for the operator.
Rotate the switch counterclockwise to standard mode (1). The rpm of the engine will now be higher when the transmission shifts.
An intermediate position (2) is also available . As the switch is rotated clockwise, the transmission will continue to shift at a lower rpm.

Press the top of the switch in order to select the preset angle for the tilt kickout of the forks.
Kickout and Positioner Control (17)
Note: You must establish a configuration for the hydraulic system if the machine was not shipped with a bucket. Use ET in order to establish this configuration. Be sure that non-AVSpare work tools will not interfere with the position sensor. Interference may occur when the bucket is fully racked back and the bucket is fully tilted back. Damage to the position sensor may occur.
Pilot Hydraulic Bucket Controls
Note: On machines with pilot hydraulic bucket controls, the operator must perform one lift cycle in order to energize the electromagnetic detents. This feature prevents movement of the implement at start-up if the lift control has been accidentally moved to the detent.
Note: The operator must activate the bucket positioner and the lift kickout by pressing the Kickout and Positioner Control (17) that is located on the switch panel. Press the top of the switch in order to activate the bucket positioner and the lift kickout. Press the bottom of the switch in order to deactivate the bucket positioner and the lift kickout. On machines with pilot hydraulic bucket controls, bucket/fork selector control is used. This switch is used in order to toggle between two different kickout positions when you are changing from a bucket to a fork.
On machines with pilot hydraulic bucket controls, the kickouts and the positioner must be adjusted manually.

The auxiliary control is used as a third hydraulic control.
|
FLOAT - Push the lever forward into the detent. The attachment will follow along the contour of the ground. |
The lever will remain in the FLOAT position until the lever is pulled out of the detent. The lever will return to the HOLD position when the lever is released.
| NOTICE |
|---|
|
Never use the FLOAT position to lower a loaded bucket. Machine damage can result from a bucket that falls too fast. |
|
LOWER - Push the lever forward in order to lower the attachment. The lever will return to the HOLD position when the lever is released. |
|
HOLD - The lever will return to the HOLD position when the lever is released from the RAISE position or from the LOWER position. The attachment will remain in the selected position. |
|
RAISE - Pull the lever backward in order to raise the attachment. The lever will return to the HOLD position when the lever is released. |
The lever is detented in the fully raised position. The lever will stay in the detent and the attachment will continue to rise until the attachment reaches the lift kickout height. Then, the lever will return to the HOLD position.
|
DUMP - Push the lever forward in order to dump a load from the bucket. |
|
|
HOLD - When you release the lever, the lever will return the HOLD position. The bucket will remain in the selected position. |
|
TILT BACK - Pull the lever backward in order to tilt the bucket backward. |
The lever is detented in the full TILT BACK position. The lever will stay in the detent and the bucket will continue to tilt back until the bucket reaches the digging angle that is preset by the tilt kickout. Then, the lever returns to the HOLD position.
Note: A machine with ride control may experience partial lowering of the lift arms when the lever is held in the DUMP position with the bucket against the bucket stops and the lift arms are fully raised. To avoid partial lowering of the lift arms, return the lever to the HOLD position.
