SECTION 4 –
ENGINE AND DRIVE SYSTEMS
Valve Manifold
Rear hydraulic steering is controlled by a
Valve Manifold (located on the underside of
the machine).
Operating AWS
All conditions must be met before AWS
will activate. First, the machine must be in
Field mode, and second, machine speed must
be less than AWS Shutoff Speed. If these
conditions are not met, the AWS Button will
remain ON, but the AWS indicator will turn
OFF, and the machine will be operating in
conventional steering mode. When
conditions are met again, AWS will
automatically activate and the AWS indicator
will illuminate.
NOTE: The machine will automatically
determine if the proper conditions
have been met and change the status
of the drive functions.
1. Ensure the machine’s drive state is in
Field mode.
2. Press the AWS Button (located on the
Machine Display Home Page - Field
Mode) to the ON (illuminated) position.
An AWS indicator (located below the
speedometer) will illuminate when AWS is
activated (requiring all conditions to be met).
Shut off Speed for AWS
Refer to “Machine Display” provided in
the
Cab Section
elsewhere in this manual for
further information.

Shut-off Speed.
NOTE: There is no warning message
associated with this. The machine
