Routine Alignment Procedure SECTION 7 SAWMILL ALIGNMENT 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).
Sawmill Alignment Routine Alignment Procedure Saw Head Tilt As the blade enters a wide log or cant, the outside of the saw head will drop down slightly. To compensate for the drop, the saw head is adjusted 1/26" (1 mm) higher at the outside. 1.
Page 105
Sawmill Alignment Routine Alignment Procedure See Figure 7-2. To adjust the saw head tilt, use the bolts located at the bottom of the saw head mast. Loosen the three sets of four retaining plate bolts. To raise the outside of the saw head, back the stop bolts out, then tighten the adjustment bolts.
Sawmill Alignment Routine Alignment Procedure Blade Guide Arm Alignment The blade guide arm moves the outer blade guide in and out. If the arm becomes loose, the blade guide will not deflect the blade properly, causing inaccurate cuts. A loose blade guide arm can also cause blade vibration.
