-44- Extreme series Jointer (Mfg. since 9/11)
adjusting Table parallelism
the tables of your jointer Must be parallel with
the cutterhead and each other (see Figure 68) to
ensure good cutting results and to reduce the risk
of workpiece kickback.

Figure 68. illustration of table parallelism
concept.
adjusting table parallelism is a task of precision,
time, and patience. Fortunately, this is considered
a permanent adjustment that should not need to
be repeated for the life of the machine.
due to the complex nature of this task, we recom-
mend that you carefully double-check the current
table parallelism to be sure that adjustments need
to be made.
Note: Typically, a tolerance of 0.005" or less
in parallelism 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.
Note: If your jointer uses a knife-style cutterhead,
you will also have to adjust the knives as the last
procedure to bring the outfeed table surface and
cutting edges of the knives to the same height.

adjusting Outfeed Table parallelism

1. disCoNNECt JoiNtEr FroM poWEr!
cutterhead knives and
inserts are extremely
sharp and can quickly
slice your hands or fin-
gers. aLWayS wear heavy
leather gloves when han -
dling these cutters to
avoid personal injury.
2. Models G9860 & G9860ZX: remove the
cutterhead guard, fence assembly, and rear
motor access cover to access the cutterhead
pulley.
Models G9953, G9953ZX, & G9953ZXF:
remove the cutterhead guard and fence
assembly, then open the rear cutterhead
cover to access the cutterhead pulley.
Note: The cutterhead pulley is used in the
following steps to rotate the cutterhead.
3. lower the outfeed table stop bolt and loosen
the table lock so that they do not interfere
with adjustments.
