Replacing And Re-Setting Knives (Model 209 Only) - Powermatic 209 Manual De Instrucciones De Operación Y Partes

4. If an adjustment to one or more of the knives
is necessary, slightly loosen the knife gib (E,
Figure 18) by turning the six screws (F,
Figure 18) into the gib (i.e. clockwise, when
facing the screw heads) with a 12mm hex
wrench. Turn the screws just enough to
relieve stress in the cutterhead without
disturbing the setting of the knives. Do this
for all four knives at the same time.
5. With the knife setting gauge (C, Figure 18)
in place over a knife (G, Figure 18), continue
to loosen the screws (F, Figure 18) until the
springs (H, Figure 18) begin raising the
knife. When knife comes in contact with the
center protrusion of the gauge, snug the gib
by lightly backing out the six screws (F,
Figure 18) against the slot (i.e. counter-
clockwise).
NOTE: At this time, tighten the knife into the
slot just enough to hold knife in position.
6. If additional knives must be reset, repeat
step 5.
7. After all knives are set with screws just
snug, back out and tighten the six screws (F,
Figure 18) against the slot starting with the
end screws first, then the center screws,
until the knife is securely held in the
cutterhead. Tighten the remaining three
knives in the same manner.
After setting or installing
knives, re-check all gib screws. Loose gib
screws can result in knives being thrown out
of the cutterhead, causing severe damage to
the machine and possible serious or fatal
injury to the operator or bystanders.
Replacing and Re-setting Knives
(Model 209 only)
If the knives are removed for sharpening, care
must be exercised in replacing and re-setting
them. Proceed as follows:
1. Disconnect machine from power source.
2. Remove six screws and upper cover (see
Figure 17).
3. To remove knife, loosen the gib (E, Figure
18) by turning the six gib screws clockwise.
Remove gib, knife and springs.
4. Remove the remaining three knives in the
same manner.
5. Thoroughly clean the knife slots, gibs,
springs and gib screws. Check the gib
screws; if the threads appear worn or
stripped or if the heads are becoming
rounded, replace them.
