Step 2 – In SEMI AUTO mode, cut a board 15-11-0 and measure and record the overall length as "Cut 1". Figure 111 Step 3 – Reduce the cut length by 0-1-0. Cut, measure and record the overall length as "Cut 2". • If both cuts are accurate, the cut length is calibrated. Go to the next section. • If "Cut 1" and "Cut 2" are both long by the same amount, or both short by the same amount proceed to the next step. • If the two cuts are off by different amounts, contact Alpine Equipment Customer Service for additional guidance. NOTE In some cases it may be necessary to repeat the cut 5-6 times to determine the root cause of the inconsistent length. Step 22 – The Figure below shows the hard stop for the T-axis. If the centerline of the cut is less than 1.75", extend the bolt. If the centerline of the cut is greater than 1.75", retract the hard stop bolt. Adjust the hard stop the distance the centerline is off. Figure 109 Step 23 – Remove the lockout/tagout. Step 24 – Power the machine up and follow normal startup and homing procedures (Section 3.1). Repeat this section until calibration is complete. 4.8 L1/L2 Belt Tension Adjustment In order to keep the ALS 4.0 running smoothly, it may be necessary to adjust the belt tension from time-to-time. Step 1 – Loosen the idler sprocket bolts on both the front and back sides of the drive assembly, then loosen the locknuts. Step 2 – Using a 9/16" wrench, adjust the belt tension assembly so that the belt can only be pulled away from the rollers by 1/4". NOTE Using an appropriate torque wrench, torque the adjustment nut to 40 in-lbs. Step 3 – Once the belt has been properly tensioned, tighten the idler sprocket bolts on both sides of the drive assembly and the two lock nuts. NOTE The tension of the L1 & L2 belts should be checked prior to calibrating L1 & L2.
