The Retro C is equipped with sensors that are constantly detecting the position of the lumber as it is loaded onto the material feed arms. As lumber passes by the sensors they measure the position of the board on each side to make sure that the board is not cross up.
he UPS supplies power (only) to the VC1s (the Brains of the Retro C) in the event of a power loss. Maintaining power to the VC1s is very useful in preventing damage or loss of settings to the computers that control the saw. The UPS guards against a loss of position they remain active and detect encoder changes in the event of power loss.
If the scrap belt is slipping on the roller or not staying centered manual adjustment is required.
Step 1: Remove the gray chain guard so you have more room to work. There are two bolts on the right side of the cover that hold it in place. Once the bolts are removed it slides right off.
The lumber guide wheel is the final point of adjustment for the lumber before it is cut. The guide wheels job is to position the lumber so that it is inline with saw blade 1 and 2. If you find that the lumber isn't being cut at all (the wheel is pushing the lumber too far to the right or isn't pushing it in far enough and is consistently cutting length off of the lumber when it is a doing a standard 90 degree cut adjusting the wheel position can help.
The Angles or Arches are the movements that pivot the blade motors to angle. That is done with a semi circular arch, 50-2 chain gearbox, motor and encoder. The gearbox for the angle movement is a hollow shaft gearbox with a shaft and sprocket to drive the number 50-2 chain around the arch. The other end of the shaft contains the encoder which tracks the position on the angle movement.
