Jointer Table
Parallelism
4. Try to fit a 0.060" feeler gauge (or combina-
tion of feeler gauges) between the cutterhead
body and the bottom of the straightedge
(Figure 59).
Note: Rotate the cutterhead to make sure the
knives do not interfere with proper measure-
ment.
The tables of your jointer MUST be parallel with
the cutterhead and each other (see Figure 57) to
reduce the risk of workpiece kickback and to help
ensure good cutting results.

Checking Outfeed Table Parallelism
The outfeed table is preset by the factory parallel
with the cutterhead. However, it is critical to check
this setting.
To check outfeed table parallelism:
1. DISCONNECT THE JOINTER/PLANER
FROM THE POWER SOURCE!
2. Remove the blade guard arm assembly.
3. Place the straightedge on the back of the
outfeed table so it hangs over the cutterhead
as shown in Figure 58.

concept.
Adjusting the tables parallel with each other is
a complex and precise task that may take more
than an hour to complete.
Due to the complex nature of this task, we rec-
ommend that you double check the current table
positions to make sure that they really need to be
adjusted before starting.
Note: Typically, a tolerance of ± 0.005" in parallel-
ism between the tables is considered acceptable.
When adjusting table parallelism, you must do
the following: 1) properly adjust the outfeed
table height and parallelism in relation to the
cutterhead, and 2) adjust the infeed table parallel
to the outfeed table, and 3) adjust the knives to
bring the outfeed table surface and cutting edges
of the knives to the same height.
