V-BELT
V-belt removal and replacement involves re-
moving the V-belt, rolling it off of the pulleys,
replacing it with a new belt, then re tension-
ing it.
Consider replacing the stock belt with a Power
Twist V-belt (see Page 31) to reduce vibration
and noise, and increase belt lifespan.
TO ADJUST/REPLACE THE V-BELT:
1. DISCONNECT JOINTER FROM POWER!
2. Remove the rear access panel and belt guard.
3. Using a 12mm
wrench, loosen the
motor mount bolts
shown in Figure 54,
raise the motor to re-
move the V-belt ten-
sion.
NOTE: DO NOT completely remove the motor
mount bolts.
4. Remove the V-belt and replace it with a new
one.
5. Lower the motor
and adjust the V-belt
tension as needed so
there is approximately
1⁄4" deflection when
the V-belt is pushed
with moderate pres-
sure, as shown in Fig-
ure 55.
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 in Fig-
ure 56.
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.
