Right Joystick (2-Button, Slide, Trigger Switch) (1) Low Idle Switch (SW-3) (2) Low Idle Switch (SW-3) ConnectionsNote: SW-2 is a trigger switch and is not shown in Illustration 9.The "One-Touch Low Idle" switch is located on the handle of the Right Joystick (See Illustration9). The one touch low idle switch will automatically reduce engine speed to 1020 RPM. Both joystick handles (LH and RH) must be in the neutral position before the engine speed is reduced.Pressure Switch

Key Start SwitchThe key start switch is an input of the engine and pump controller. The key start switch informs the ECM of an attempt to start the engine. Then, the ECM initiates the start procedure.The starting switch is a four position switch, and connects the battery supply terminal B to the other terminals.Usually the position of the switch is the OFF position. At this time the connected terminals are the B and C terminals only.When the switch is in the ON position, the connected terminals are B and R only. The keyswitch will remain in this position without handling.When the switch is in the Start position, the connected terminals are B, R, and S. The keyswitch must be handled to remain in this position.When the keyswitch is in the EMERGENCY STOP position, the connected terminals are B and A only. The keyswitch must be handled to remain in this position.During normal machine operation, the start terminal of the key start switch is open. If the key start switch is placed in the START position, the start terminal will close. +Battery voltage is supplied to the start terminal. When all starting conditions are satisfied, the ECM sends a +battery signal to the start relay and engine cranking begins.Note: After the key start switch is initially turned to the START position, the switch will not return to the START position from the ON position. The switch must be turned to the OFF position first. Then, the switch can be turned to the START position.Toggle Switch
