    Sawmill Alignment Routine Alignment Procedure SECTION 7 SAWMILL ALIGNMENT 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 saw- mill over rough terrain).

  • Page 93: Blade Guide Arm Alignment

    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.

    Sawmill Alignment Routine Alignment Procedure Blade Guide Vertical Tilt Alignment The blade guides should be adjusted properly in the vertical plane. If the blade guides are tilted vertically, the blade will try to travel in the tilted direction. A Blade Guide Alignment Tool (BGAT) is provided to help you measure the vertical tilt of the blade.
