Joystick Power Cut Off Switch:

A Joystick Supply Cut Off Switch (Master Switch) can be added to the Machete in order to eliminate the possibility of damage caused by the joystick moving while roading the machine over rough terrain. Inadvertent movement of the controller can result in uncontrolled movement of the boom which may result in damage to the boom rest, the tractor or other areas.

Parts needed:

-------------	2	12 or 14 gauge wire butt connectors (furnished by installer)
-------------	a/r	14 gauge wire cut to length, preferably red wire (furnished by installer)

Procedure:

2.Find the RED Voltage supply wire which supplies electrical power to the Joystick.

3.Locate a suitable mounting position within easy reach of the operator, and run the two wires from the new switch to the red power supply wire. Cutting the existing power supply wire connect the two butt connector from the switch to the cut power supply, see drawing.
