Cutterhead Guard
Adjusting Cutterhead Guard
The cutterhead guard is a critical safety
feature of this jointer. You MUST install and
verify its operation before using the jointer!
Failure to properly install this guard will
greatly increase the risk of serious personal
injury.
The cutterhead guard is designed to reduce the
risk of accidental contact with hands or fingers
with the spinning cutterhead. When properly
installed and functioning correctly, the guard auto-
matically rotates clear of the cutterhead during the
cutting operation and then springs back over the
cutterhead as soon as the operation is complete.
In order to function as intended, the guard must
be installed as low as possible over the infeed
table without actually touching it (approximately
⁄
" above infeed table), and it must have enough

spring tension at the mounting shaft to quickly
reposition itself against the fence after it is rotated
away from the cutterhead and released. Before
performing rabbeting operations, adjust guard
height to just clear outfeed table.

Set fence to 90° and move it all the way back,
then pull cutterhead guard (see Figure 70)
and let it go.
— If cutterhead guard springs back over
cutterhead, contacts fence, and does not
drag across infeed table, then it is properly
adjusted.

over cutterhead, does not contact fence,
or drags across infeed table, then proceed
