Needle Case Removal

This repair requires timing and other adjustments and should be done by a Melco authorized service technician.

CAUTION!! DO NOT disassemble the needle case any further than what is provided in this manual. If you do so, the alignment of the needle case will be severely compromised and extremely difficult to reset without the proper fixtures used at the factory.

1. Turn ON the AMAYA and load the AMAYA Control Panel software. Click on "Maintenance" menu and then "Head Timing" tab. Click on the "Head Up" button to bring the head to the HEAD UP position. If the machine is jammed or will not go to the head up position, contact Melco Technical Support for instructions.

2. Color change to either Needle 5 or 6.

WARNING! Do not proceed without engaging the emergency stop button or by turning the machine off. The machine may begin operating if you do not do so. This can result in severe damage to the machine and/or personal injury. You do not need to disconnect the power input cord from the machine.
