NOTICE When certain work tools are installed, the work tools can contact the stabilizers. This interference can occur when the boom is retracted and the work tool is rotated fully forward. Always check for interference when first operating a new work tool. Travel with the work tool lowered as far as possible with adequate ground clearance. Travel with the boom fully retracted so that you have good visibility and so that the machine has good stability. Maintain traction by avoiding excessive downward pressure on the work tool. When the machine is operating on a slope, position the heaviest end of the machine uphill.

The diverter valve allows the operator to direct hydraulic oil to the hydraulic quick coupler function or to the work tool. Note: The electrical diverter valve may not be installed on certain merchandising arrangements. Consult your Caterpillar Dealer for installation of the connection points for the auxiliary hydraulic service with manual quick couplers. Note: A dual diverter valve is installed as an option. Refer to the topic "Joystick Control" in Operation and Maintenance Manual, "Operator Controls" for more detailed information on operating the boom and the work tools.
