- Rotate the hold-down bar out of the way by removing the locknut and washer from the holddown adjustment lever above the angle block. This will expose the angle knife cover plate.
- Loosen the two hex bolts but do not remove them, as these hold the half-moon pieces above the blade.
- Remove the locknut from the through-bolt and remove the cover plate.
- Remove the upper angle knife by pulling from the left and right corners.
- The upper angle knife has a different radius on each corner. Rotate it so that the corner that best matches the angle being cut is pointed down.
- Reinsert the knife. Make sure that it is snug against the half-moon pieces and that there is clearance on all sides of the through-bolt. This is to ensure that the through-bolt does not take the force of the shearing action, as this could damage your machine.
- Replace the angle knife cover plate.
- Tighten the two hex bolts until they are sung, then give them an eighth of a wrench turn.
- Replace the locknut on the through-bolt. It should be snug, but you should still be able to move the angle knife from side to side with a minimal amount of effort.
- Rotate the hold-down bar back into place and rethread the washer and locknut on the bolt. Do not torque the locknut. The washer should have plenty of wiggle room.
- If necessary, watch the angle knife from the back of the machine during a test shear. The blade should find the fillet before it shears the angle. If the blade is too tight, it will start to shear before finding the fillet. If it is too loose, it may bounce between the sides before beginning the shear.
