-32- Ultimate Series Jointers
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. Note—
The cutterhead knives should protrude above the
cutterhead 2mm (0.079"). The knife jig included
with the jointer is designed to set the knives with-
in this height.
To set the knives:
1. Unplug the machine from the power
source!
2. Open the access door on the back of the
machine, just below the fence adjustments.
3. Turn the cutterhead pulley until the surface of
the cutterhead is at top dead center.
4. Adjust the outfeed table to a height of 2mm
above the surface of the cutterhead.
5. Turn the cutterhead pulley to reveal one of
the knives.
6. 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 (Figures 34 and 35). Note—The
gib bolts turn clockwise to loosen and coun-
terclockwise to tighten (when facing the head
of the bolt).
