The knives are locked into the cutterhead with
wedge-type gibs and gib bolts. Jack screws under
the knives may be substituted with springs to help
in the setting process. It is advised that the jack
screws be removed when using the springs. To
set the knives:
1. UNPLUG THE PLANER!
2. Remove the upper cover to expose the cut-
terhead.
3. Loosen the gib bolts until the knife is loose
in the slot. The gib bolts turn clockwise to
loosen and counterclockwise to tighten
(when facing the head of the bolt). See
Figure 19.
ADJUSTMENTS USING SPRINGS
Figure 19. Side view with springs.
When making adjustments, all three knives
must be adjusted the same. Do not adjust
one knife without adjusting the others as
well. Improper knife height adjustment can
result in damage to knives, poor planer per-
formance and possible operator injury.
Planer knives are dangerously sharp. Use
extreme caution when inspecting, remov-
ing, sharpening, or replacing knives into the
cutterhead. Substantial risk of injury!
Figure 20. Tightening knives in cutterhead.
4. Place the knife setting gauge on the cutter-
head as described previously, so the feet
are securely planted on the cutterhead.
Make sure the gauge extension rod is par-
allel to the cutterhead to maintain accuracy.
5. The downward pressure provided by the
gauge will set the knives at a uniform pro-
trusion of approximately .070" above the
cutter.The knife height should vary no more
than .002"-.003" across the length of the
cutterhead.
6. Maintain a constant pressure on the gauge
while re-tightening the gib bolts. See Figure
20.
7. Repeat the same procedure on the remain-
ing knives. As mentioned before, the stan-
dard knife setting gauge is satisfactory for
reasonably accurate knife setting tasks.
