Adjusting Knives
The knives in the Model W1679 come from the
factory with jack screws installed. Springs are
also included as an option for knife adjustments,
depending on your preference.
Figure 22
shows
an illustration of the cutterhead components.
The knife position should be as precise as possi-
ble in the cutterhead. All knives should be with-
in .002" from one end to the other and within
.002" from one knife to another.
To adjust the knives:
1. Unplug the jointer!
2.
Remove the cutterhead guard from the
table, so that you have clear access to the
top of the cutterhead.
3.
Remove the pulley cover at the back of the
machine and slowly turn the cutterhead
with the pulley until one of the knives is
exposed and is easily accessible.
4.
Loosen the cutterhead gib bolts so that the
knife is loose.
5.
Place the knife gauge on the cutterhead as
described in the “Checking Knives” instruc-
tions and as shown in
Figure 22
.
6. Jack Screws
—Adjust the jack screws with
an Allen wrench until the knife edge barely
touches the contact point on the knife set-
ting jig. Snug the gib bolts but do not fully
tighten. Repeat this step with each jig
screw on each knife.
Springs—
The springs will push the knife
against the cutterhead to the proper height
(.070" above cutterhead body). Keep down-
ward pressure on the jig until you tighten
the gib bolts. Repeat this step with the
other knives, then snug the gib bolts with-
out fully tightening them.
7.
Start at the beginning knife and slightly
tighten each gib bolt on each knife in the
sequence shown in
Figure 23
. Repeat this
step two or three times until all gib bolts
are completely tight.

NOTICE
Uneven tightening of the gib bolts may cause
the cutterhead to become unbalanced,
which will lead to premature wear and tear
of the knives and produce poor results!
Wear heavy leather gloves when loosen-
ing/tightening gib bolts in case the wrench
slips and your hand hits the knife. Planer
knives are dangerously sharp. If care is not
taken, serious injury may occur.
