Setting Knives
The Grizzly 8" Jointers come with both jack
screws and springs to provide you with two
options for cutterhead adjustments (see Figure
52). Note—Only one of these options is needed
to set the knives—see step 5* for clarification.

To set the knives:
1. Disconnect the jointer from the power
source!
2. Remove the cutterhead guard from the table
and lower the infeed and outfeed tables as
far as they go. This will give you unrestricted
access to the cutterhead.
3. Remove the belt guard to expose the cutter-
head pulley.
4. Rotate the cutterhead pulley to give you
good access to one of the cutterhead knives.
5. Loosen the cutterhead gib bolts, starting in
the middle, and alternating back and forth
until all of the gib bolts are loose, but not
falling out.
*Note—If this is the first time you are setting
the knives, remove the gib and knife from the
cutterhead. Decide which adjustment option
you are going to use between the jack
screws and the springs. If you decide to use
Setting the knives correctly is crucial to the prop-
er operation of the jointer and is very important in
keeping the knives sharp. If one knife is higher
than the others, it will do the majority of the work,
and thus, dull much faster than the others.
The knives on your Grizzly 8" Jointer should be
set .051" (1.3MM)-.060" (1.5MM) higher than the
cutterhead. The knife jig included with the jointer
is designed to set the knives within this height.
