NOTE: After the first 16 hours of belt life, re-
tension the belt, as it will stretch and seat dur-
ing this time.
6. Tighten the motor mount bolts, replace the
rear access panel and belt guard.
INSPECTING KNIVES
The height of the knives can be easily and
quickly inspected with the included knife set-
ting gauge. This inspection will ensure that the
knives are set to the correct height in the cut-
terhead.
· Tools Needed; Knife Setting Gauge.
To inspect the knives:
1. DISCONNECT JOINTER FROM POWER!
2. Remove the cutterhead guard or block it out
of the way.
3. Lower the infeed table to the 1⁄2" scale mark
and lower the outfeed table as needed.
4. Remove the rear
panel and rotate the
V-belt so a knife is ex-
posed.
5. Place the knife
gauge on the cutter-
head, directly over a
knife, as shown.
6. Carefully inspect how the gauge touches the
cutterhead and the knife.
· If both outside legs of the gauge sit firmly
on the cutterhead and the middle pad just
touches the knife, then that knife is set cor-
rectly. (Repeat this inspection with the other
knives.)
· If the gauge does not sit firmly on the cut-
terhead and touch the knife edge as described,
then reset that knife. (Repeat this inspection
with the other knives before resetting.)
SETTING/REPLACING KNIVES
Setting the knives correctly is crucial to the
proper 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.
The knife gauge included with the jointer is
designed to set the knives at 0.063" (1/16"),
which is the correct distance all the knives
should protrude above the cutterhead.

This machine comes with jack screws for cut-
terhead adjustments.
TO SET OR REPLACE THE KNIVES:
1. DISCONNECT JOINTER FROM POWER!
2. Remove the cutterhead guard from the ta-
ble and lower the infeed and outfeed tables as
far as they go. This will give you unrestricted
access to the cutterhead.
3. Remove the rear access panel to expose the
cutterhead pulley.
4. Rotate the cutterhead pulley to give you
good access to one of the cutterhead knives.
5. Loosen the cutterhead gib bolts, starting in
the middle and alternating back-and-forth un-
til all of the gib bolts are loose but not falling
out.
· If this is the first time you are setting the
knives, or if you are replacing them, remove a
gib and knife from the cutterhead. Clean the
gib and clean inside the cutterhead slot to re-
move all pitch or sawdust. Coat the knife and
gib with a metal protector.
6. Position the knife gauge over the knife as
shown in Figure 58 and loosen the gib bolts
until the knife is completely loose.
7. Using a 2.5 mm hex wrench, rotate the jack
screws in the access holes to raise or lower the
knife. When the knife is set correctly, it will
barely touch the middle pad of the knife set-
ting jig. Snug the gib bolts tight enough to just
hold the knife in place. Repeat Steps 5-7 with
the rest of the knives.
