  • Page 108: Sawmill Alignment

    SECTION 5 SAWMILL ALIGNMENT Pre-Alignment Procedures The Wood-Mizer sawmill is factory aligned. Two alignment procedures are available to realign the sawmill if necessary. The Routine Alignment instructions should be performed as necessary to solve sawing problems not related to blade performance. The Complete Alignment procedure should be performed approximately every 1500 hours of operation (sooner if you regularly transport the sawmill over rough terrain).

  • Page 109: Frame Setup

    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: LT40S AH: Adjust the two middle outriggers on the main frame tube down just enough to lift weight from the trailer tire.
  • Page 110 Sawmill Alignment Blade Installation And Alignment WARNING! Do not spin the blade wheels by hand. Spinning the blade wheels by hand may result in serious injury. 3. Turn off the engine, remove the key and check the position of the blade on the blade wheels.
  • Page 111 Sawmill Alignment Blade Installation And Alignment See Figure 5-3. For horizontal adjustment, use the horizontal adjustment nuts. If the blade is running too far back on the drive-side blade wheel, locate the long U-bolt on the right which mounts the bearing housing to the mounting plates. Loosen the hex nuts on the U-bolt (on the back side of the back plate).
