Setting the knives correctly is crucial to the proper
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.

To set or replace knives, do these steps:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove cutterhead guard from table and lower infeed
and outfeed tables as far as they go. This will provide
unrestricted access to cutterhead.
3.
Remove cabinet rear access panel to expose cutterhead
pulley.
4.
Rotate cutterhead pulley to provide good access to
cutterhead knives.
5.
Loosen cutterhead gib bolts, starting from center, and
alternating back and forth until all gib bolts are loose,
but not falling out (see
Figure 58
).
The first time you set or replace a knife, remove
gib and knife from cutterhead. Clean gib and inside
cutterhead slot to remove all pitch or sawdust. Coat
knife and gib with a light amount of oil or other metal
protectant.
