Adjusting The Feed Belt Tension

1) Turn the power switch to the OFF position and
unplug the power cord from the machine.
2) Adjust the A and B screws as shown in Figure
5 to narrow the gap between the feeding pulley and
the guide plate underneath the feed belt so that the
clearance between the feed belt and the metal

approximately 0.5 mm.
This procedure may need to be applied if there is
coin slippage begins to occur as the feed belt wears
over time or when replacing the feed belt.
