6. Inspect the cutting edge of the knives for
nicks or wire edge. Hone the knives slightly
using a stone or if the knives are to be
sharpened, maintain a cutting angle of 35
degrees.
7. Insert springs, knife and gib into slot of
cutterhead. Back out screws just enough to
hold the knife in the cutterhead.
8. Place knife setting gauge (Figure 19) over
knife.
9. While holding down the knife gauge, loosen
all six screws by turning them into the gib
until the cutting edge of the knife comes in
contact with the protrusion of the gauge.
Snug up the gib by slightly backing out the
six screws against the slot.
NOTE: At this time, only tighten the knife
into the slot just enough to hold the knife in
position.
10. Replace and re-set the other three knives in
the same manner.
11. After all four knives are set with the screws
just snug, back out and tighten the six
screws against the slot starting with the end
screws first and then the center screws until
the knife is securely held in the cutterhead.
Tighten the remaining three knives in the
same manner.
After replacing and checking
knives, check again carefully. Make certain
the direction of knives is correct and all 24
gib screws are tightened securely.
Replacing or Rotating Knife Inserts
(Model 209HH only)
The knife inserts on the model 15HH are four-
sided. When dull, simply remove each insert,
rotate it 90° for a fresh edge, and re-install it.
Use the provided screwdriver with the socket
adaptor to remove the knife insert screw. See
Figure 20. It is advisable to rotate all inserts at
the same time to maintain consistent cutting.
However, if one or more knife inserts develops a
nick, rotate only those inserts that are affected.
Each knife insert has an etched reference mark
so you can keep track of the rotations.
IMPORTANT:
When removing or rotating
inserts, clean saw dust from the screw, the
insert, and the cutterhead platform. Dust
accumulation between these elements can
prevent the insert from seating properly, and
may affect the quality of the cut.
Figure 19 repeated
Figure 20 – Model 209HH only
Before installing each screw, lightly coat the
screw threads with machine oil and wipe off any
excess.
Securely tighten each screw which holds the
knife inserts before operating the planer!
Make sure all knife insert
screws are tightened securely. Loose inserts
can be propelled at high speed from a
rotating cutterhead, causing injury.
