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.
1.
Adjust the blade guide arm in to 1/2" (15 mm) from fully closed.
2.
Manually try to move the arm up and down. If you can move the arm by hand, you will
need to tighten the arm rollers.
See Figure 7-3.
Remove the blade housing cover to access the blade guide arm roller
mounting bolts. The blade guide arm rollers are mounted on cam-shaped bolts. Turning
the bolts will cause each roller to move up or down. If the inner lower roller is loose, adjust
the inner top roller down. If the outer lower roller is loose, adjust the outer lower roller up.
Retighten the jam nuts and recheck the tightness of the bottom rollers.
