Setting Knives
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.
The knife jig included with the jointer is designed to
set the knives at the correct height.
The Model ST1010 comes with both jack screws
and springs to provide you with two options for
cutterhead adjustments (see Figure 59).
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 cabinet cover to expose the V-belt.
4. Use the V-belt to rotate the cutterhead to access
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.
Inspecting Knives
The height of the knives can be easily and
quickly inspected with the knife setting jig. This
inspection will ensure that the knives are set in
the cutterhead as they should be. Usually this is
done before calibrating the outfeed table or when
troubleshooting.
To inspect the knives:
1. DISCONNECT THE JOINTER FROM THE POWER
SOURCE!
2. Remove the cutterhead guard or block it out of
the way.
3. Lower the infeed table to the
1
⁄2" scale mark.
4. Place the knife jig on the cutterhead, directly
over a knife, as shown in Figure 58.

Middle Pad
5. Carefully inspect how the jig touches the
cutterhead and the knife.
— If both outside legs of the jig sit firmly on the
cutterhead and the middle pad just touch-
es the knife, then that knife is set correctly.
(Repeat this inspection with the other knives.)
— If the jig does not sit firmly on the cutterhead
and touch the knife edge as described, then
reset that knife. (Repeat this inspection with
the other knives before resetting.)
