    SECTION 5 SAWMILL ALIGNMENT Pre-Alignment Procedures The Wood-Mizer sawmill is factory aligned. 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 square- ness of your cuts.

    Sawmill Alignment Frame Setup Frame Setup Stationary sawmills should be setup on firm, level ground before proceeding with align- ment. Shim the feet so the weight of the sawmill is evenly supported. Portable sawmills should also be setup on firm, level ground. Adjust the two middle out- riggers on the main frame tube down just enough to lift weight from the trailer tire.
