The autodig system is designed to perform the operations of a loading cycle of an aggregate mix with minimal effort by the operator. Loading this type of material is generally repetitive and a high level of skill is required to maintain a consistent level of productivity during such loading cycles. This feature will fully load a bucket at consistent loading times.Note: The autodig system is only available on machines that are equipped with electrohydraulic bucket controls and command control steering.Each position of dig mode switch (1) is programmed with the appropriate transmission speed for loading various types of material. The autodig system will only function up to the third speed. The autodig system will downshift the transmission to the proper speed. Only settings one and two are allowed in second speed. All nine settings are allowed in first speed.Note: If the transmission is in first speed and dig mode switch (1) is programmed for second speed, the autodig system will not upshift the transmission.Kickout set switch (3) will record the position of the lift linkage at the end of a loading cycle. If the kickout height has been set successfully, one beep will be heard. If setting the kickout height is unsuccessful, multiple beeps will be heard.Operating Modes of the Autodig System
Dig mode switch (1) allows the operator to select different settings for different types of material for loading. Rotate the switch counterclockwise in order to load light material. Rotate the switch clockwise in order to load heavy material. Intermediate positions are available. The settings for the first nine positions are preset. An operator's own discretion is advised.Press the top of operating mode switch (2) in order to turn on the autodig system. One beep will be heard. This will indicate that the system is in the automatic pile detection mode. The switch will return to the center position. Press the top of switch (2) in order to toggle the autodig system to the operator triggered mode. Two beeps will be heard. Press the top of switch (2) again in order to toggle the autodig system to the record mode. Three beeps will be heard. Press the bottom of operating mode switch (2) in order to turn off the autodig system.Automatic Pile Detection Mode
The autodig system will be set to the automatic pile detection mode upon initial activation. This means that the loading cycle will automatically begin when the bucket contacts the pile. Indicator (4) will light and one beep will be heard when the autodig system is in the automatic pile detection mode. The operator does not need to move the bucket controls during automatic loading. Lower the bucket to the ground. Drive the machine into the pile. Do not move any of the controls. The autodig system will automatically load the bucket. An audible alarm will briefly sound at the beginning of the loading cycle and at the end of the loading cycle. The machine can now be driven to the hauling unit.Operator
