PX|12 Quadtec:I Planer \ Maintenance
Figure 14: Cutterhead
Figure 15: Auto Lock
1. The knife inserts on the 12” Planer are four-sided. When dull, remove each knife, rotate it 90° for a
fresh edge, and re-install it. No further adjustment is necessary. Use a Torx wrench (T20) to remove the
knife insert screw. Use a second Torx wrench to hold the cutterhead (from rotating) in position (in
another screw).
DO NOT USE YOUR HAND TO HOLD THE CUTTERHEAD! See Fig. 14.
2. It is advisable to rotate all inserts at the same time to maintain consistent cutting. However, if one or
more knife inserts develops a nick, rotate only those inserts that are affected. Each knife insert has an
etched reference mark so you can keep track of the rotation. Torque each screw to 52-60 in/lbs.
3. IMPORTANT: When removing or rotating inserts, clean sawdust from the screw, the insert, and the
cutterhead platform. Dust accumulation between these elements can prevent the insert from seating
properly and may affect the quality of the cut.
4. Before installing each screw, lightly coat the screw threads with machine oil and wipe off any excess.
Securely tighten each screw which holds the knife inserts before operating the jointer!
