Maintenance & safety
Unplug the machine before wiring, replacing parts or working on the control board. Don't adjust voltage controls with wet hands or near exposed live wiring.
Use only compatible power supplies, motors, coin acceptors, photo eyes, counters, speakers and RGB lights.
Clean the prize chute and photo eye regularly. Dust, stickers or prize packaging can trigger false detection.
Check the carriage rails, belts, ropes and claw for wear, and make sure all connectors are seated after moving the machine.
Write down your final settings after tuning.
