    Alignment Pre-Alignment Procedures SECTION 6 ALIGNMENT Pre-Alignment Procedures Periodically check the sawmill alignment and adjust if necessary. This chapter explains how to align the entire sawmill. Care should be taken in performing these steps. Sawmill alignment determines the accuracy and squareness of your cuts. The sawmill alignment steps are: 1.

Blade Wheel Alignment The blade wheels should be adjusted so they are level in the vertical and horizontal planes. If the blade wheels are tilted up or down, the blade will want to travel in the tilted direction.

    Alignment Blade Height Scale Adjustment 6.12 Blade Height Scale Adjustment After the entire sawmill has been aligned and all adjustments made, check that the blade height scale indicates the true distance from the blade to the bed rails. 1. The maximum distance between the scale and the scale indicator should be 5 mm. If it is different, loosen the indicator bracket mounting bolts and move the bracket in the horizontal plane until the correct distance is obtained.
