Tilt And Auxiliary Speed Adjustment Each function (Tilt, Aux. 1, Aux. 2) can be preset at any one of the seven pump motor speeds or OFF. The speeds are set by nine auxiliary hydraulic speed control switches (SW2 through SW10) on the logics board. Three switches (SW2, SW3 and SW4) control tilt speed. Three switches (SW5, SW6 and SW7) control Aux. 1 speed. Three switches (SW8, SW9 and SW10) control Aux. 2 speed. The charts that follow show how the auxiliary hydraulic speed control switches relate to hydraulic motor speed and transistor pulsing.
