Sheartec II Knife rotation/replacement
CAUTION!
KNIFE INSERTS ARE DANGEROUSLY SHARP. USE EXTREME CAUTION WHEN INSPECTING, REMOVING, OR REPLACING
KNIFE INSERTS.
WARNING
·
TURN PLANER OFF AND DISCONNECT POWER BEFORE PERFORMING ANY MAINTENANCE OR ADJUSTMENTS!
·
MAKE SURE ALL KNIFE INSERT SCREWS ARE TIGHTENED SECURELY. LOOSE INSERTS CAN BE PROPELLED AT HIGH
SPEED FROM A ROTATING CUTTERHEAD, CAUSING INJURY.
TORQUE EACH SCREW TO 52-60 IN/LBS.
·
KNIVES ARE EXTREMELY SHARP. BE VERY CAREFUL WHEN HANDLING KNIVES. FAILURE TO COMPLY MAY CAUSE
SERIOUS INJURY
The knife inserts on the 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 (T25) 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. 13.
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.
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.
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!
