4.2.3 Sweep Operation & Adjustments
4.2.3.1 Sweep Operation
The sweep should operate smoothly in all locations and should not rub the machine or the pin
deck. The position of the Sweep is controlled by the Chassis using the Sweep drive motor encoder
for position indication and the home disc and encoder for an absolute reference of the home
position.
4.2.3.2 Sweep Adjustments
Note: Sweep adjustments should be made on both sides of the machine.
1. With the sweep at the Home position:
a. Adjust the short connecting rod (see Figure 4.2-25) to obtain a starting length of 10-1/8 inches
center to center between the rod end openings. Tighten the jam nuts.
Note: Sweep travel is determined by the length of the short connecting rod. If this rod is
too long, the sweep will collapse into the pit. If too short, the sweep will hit the
frame of the machine at the home position.
