SHEARTEC 2 CUTTERHEAD 

WARNING:

 Knife inserts are dangerously sharp.  

Use extreme caution when inspecting, 

removing or replacing knife inserts. 

The knife inserts on the Jointer are four-sided. 

When dull, simply remove each insert, rotate it 

90° for a fresh edge, and re-install it. No further 

adjustment is necessary. Use the two provided 

torx wrench to remove the knife insert screw. 

Use one of the torx wrenches to help hold the 

cutterhead in Position, and the other to remove 

the screw. See Figure 19A. 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 rotati

ons. 

 
IMPORTANT: When removing or rotating 

inserts, clean saw dust 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! 

Make sure all knife insert screws are tightened 

securely. Loose inserts can be propelled at high 

speed from a rotating cutterhead, causing injury.
