  • Page 5: Removing / Installing The Blade

    REMOVING / INSTALLING THE BLADE Your bandsaw is designed to handle several blade widths ranging from 1/4” and 3/8” used for tight radius curves, up to 1/2” and 3/4” for larger radius curves or for cutting thicker stock. BLADE CLEARANCE Note: When performing blade installation, removal, tensioning or tracking, maximum clearance between the blade and both upper and lower blade guide assemblies is required to minimize friction, which would be damaging to the blade.

  • Page 6: Adjusting The Blade Guard For Depth Of Cut

    ADJUSTING THE BLADE GUARD FOR DEPTH OF CUT The blade guard can be moved up or down to accommodate the height of the work to be cut. To prevent the blade (which is flexible and which would not otherwise be supported) from slipping out of position during cutting, and to reduce risks of injuries, a minimum amount of blade should be exposed.

Turn the micro lower adjust nut G to move the guide screw E to set the gap between the guide block block assembly in or out until the guide blocks are and the blade.

  • Page 8: Cutting Curves

    CUTTING CURVES • When cutting curves, carefully turn the workpiece so the blade follows without twisting. If the curve is so sharp that you repeatedly back up and cut new kerf, use a narrower blade, or a blade with more set (teeth further apart). When a blade has more set, the workpiece turns easier but the cut is rougher.

  • Page 12: Recommended Adjustments

    RECOMMENDED ADJUSTMENTS ADJUSTING THE 90º TABLE STOP AND RE-ALIGNING THE ANGLE POINTER To ensure that your 90º cuts are square and that angled cuts are accurate with the angle indicator scale, the table default position must be set to 90º to the blade and the angle indicator pointer must be set to read 0 when the table is in the default (90º) position.

  • Page 13: Adjusting Blade Tracking

    ADJUSTING BLADE TRACKING Blade tracking means centering the blade on the wheels A. Ideally, the blade should stay relatively centered on both the upper and lower wheels. Due to natural variations in castings, blade thickness or density and tire wear, absolute perfect centering alignment is rarely attainable.
