If the bearings are loose on the motor side, reset the distance between the arms and the belt
tension bracket (Image 8). This will allow for the assembly to fit properly into the arms. Secure
the bearing set screws (Image 9). If the bearings are tight, manually align the chain. Loosen the
set screws for the sprocket, take a measurement from the inside of the bracket to the chain.
Both drive and roller sprocket should be the same (Image 10).

2. The chain is on, but my belt still won’t turn.
Using a digital Volt/Ohm meter in the VDC setting (Image 11), check the voltage going to the belt motor. The motor operates on a
0v - 90v DC scale. Depending on where the speed control is set will determine the voltage reading. Unplug the belt motor, the side
of the plug with the white/black wires is the power side (Image 4). Insert the meter’s probes into the plug as show in image 12.
With the probes inserted take note of the reading on the meter, if it displays a negative reading, swap the probes and take another
reading.
