6. Drive Orientation Override
When the boom is swung over the rear in
either direction, the Drive Orientation indica-
tor will illuminate when the drive function is
selected. Push and release the switch, and within 3 seconds
move the Drive/Steer control to activate drive or steer.
Before driving, locate the black/white orientation arrows on
both the chassis and the platform controls and match the
control direction arrow to the intended chassis direction.
7. Drive/Steer Enable
Located on the top of the Drive Steer Joystick,
the button must be pushed in for the Drive/
Steer control to function. If at any time the
Enable Switch is pushed in and no function is
operated for a period of 3 seconds, the switch will "time-out"
and the switch must be cycled again to renew normal func-
tions.
8. Drive/Steer
Proportional dual axis joystick is provided
to control drive and steer. Push forward to
drive straight forward. The joystick is pro-
portional, with the drive speed increasing
as the joystick is moved further from its neutral position.
Moving the joystick forward and to the side steers the
machine in the direction of the side displacement of the joy-
stick. With the joystick positioned all the way to the side and
slightly forward, the machine will turn in place with one
track stopped and the other one turning the machine
around the center of the stopped track.
Moving the joystick to the side (no dislocation in the forward
or aft direction) will turn the machine by counter-rotation
around the center of the machine by powering the tracks in
opposite directions.
Pulling the joystick back and to the sides controls speed and
direction of drive in reverse.
NOTE: Both drive and steer functions work in the opposite direction
when the boom is positioned over front of the chassis (over idler
wheels).
