Adjusting the Cutting Knives

WARNING: Be sure the machine is turned OFF and

UNPLUGGED before attempting any adjustments.

The Cutter Head assembly can be accessed by removing the cover from the top of the machine.

1.Remove the top cover (326) from the machine by removing the bolts securing it.

. Please refer to Figure 11 when checking knife ad- justment. Position the knife Gauge (E) on the cutter head and knife blade as shown. The gauge must contact the knife blade and the cutter head at all

three points shown. The blade is adjusted too low if there is a visible space between the blade edge and the gauge. The knife blade is too high when the gauge rocks from side to side on the cutter head when contacting the knife blade.

3.To adjust the blade setting, loosen the locking nuts (A) just enough to allow the blade (C) to move against the Lock Bar

(B). To raise the knife blade, turn adjustment screw (D) counter- clockwise. To lower the knife blade, turn the adjustment screw clockwise and press down on the blade.

Note: It is important that you adjust the blade along its entire length, so the blade has a consistent depth.

4.When the knife blade is properly adjusted, tighten the locking

nuts (A) firmly to lock it in place. Be sure these nuts are on tight. Figure 11. Knife Blade Gauge Re-check alignment to be sure the knife blade did not slip during tightening.
