SAE/BHL Joystick Operating Modes
There are two operating modes available for the joysticks:
•
Society of Automotive Engineers (SAE) mode
•
Backhoe Loader (BHL) mode
Pattern Change (SAE/BHL) Valve
The pattern change valve (1) is behind the left-front door,
below the engine air cleaner.
The valve changes control of the boom and the arm from
one joystick to the other. The position shown is the SAE
mode position. To change to the BHL position, pull up on
the pin and rotate the bar to the right. Release the pin to lock
the bar in place:
•
In SAE mode, the arm is controlled using the left
joystick, and the boom is controlled using the right
joystick.
•
In BHL mode, the arm is controlled using the right
joystick, and the boom is controlled using the left
joystick.

outside the cab window while the machine is running. Know the positions and functions of
each joystick. Failure to observe and follow this warning may cause unexpected movement of
the machine, which could result in death or injury.
NOTICE!
Shut down the engine before adjusting the pattern change (SAE/BHL) valve. Failure to
