L. Truck Start Switch
This is a momentary switch used to start or stop the truck engine. Holding the
switch in the start position activates the starter. Release the switch as soon as the
engine starts. Activate and hold the switch in the “OFF” direction to shut the
truck off. Once the engine stops completely stops running, release the switch. If
this switch is released while engine is still turning over, the truck will restart.
M. Remote Control Switch
On units equipped with remote controls, this switch activates the remote controls.
Set the switch to the “ON” position to activate the remote controls. Set this position
to the “OFF” position to turn remotes off. See operating instructions in the “Optional
Remote Controls” section of this manual.
N. Auger Shift
This switch is used to shift the digger into either “HI” or “LOW” speed. For most
digging operations, select “LOW” speed for digging and “HI” Speed for cleaning the
flighting. If soil conditions allow, the digger can be used to dig in high speed.
O. Digger Latch
This momentary switch opens and closes the digger stow latch cylinder. To un-stow
the digger, use the Digger Control Joystick (B) to lift the digger off the latch, and
press the switch to the “OPEN” position. Once the latch cylinder has retracted and
the latch is open, lower the digger using the Digger Control Joystick.
To stow the digger, first ensure the latch is open (if not, see previous paragraph to
open the latch). Next, use the Digger Control joystick to raise the digger into the
stow bracket and is above the latch, and then push the switch into the “CLOSE”
position. Once the cylinder extends and the latch is closed, the digger is stowed.
NOTE: Ensure the latch is completely closed before continuing crane operation, or
transporting the unit.
