When the table is exactly level with the knives
at the highest point of revolution, tighten
lockhandle (A) Fig. 14, and turn adjusting bolt
(C) Fig.15, until it bottoms; then tighten lock-
nut (A). Bolt (D) is also a positive stop for the
lower limit of the outfeed table. We suggest
that this stop also be tightened when the out-
feed table is set level with the knives. This will
prevent the outfeed table from accidentally
being lowered.
ADJUSTMENTS
The jointer comes with two V-belts installed
and properly tensioned to the cutterhead and
motor pulley. If it becomes necessary to adjust
belt tension, proceed as follows:
1. DISCONNECT THE MACHINE FROM THE
POWER SOURCE.
2. Loosen knob (A) Fig.16 and pull the handle
latch (B) upwards and open rear hinged door
(C).
3. To adjust belt tension, turn nuts (A) and (B)
Fig. 17 to move motor plate (C) up or down
until there is approximately 1/2" deflection in
the center span of the V-belts (D) using light
finger pressure.
ADJUSTING SPRING TENSION OF CUTTERHEAD
GUARD
The cutterhead guard (A) Fig. 18, completely
covers the cutterhead. During operation the
material being jointed or planed pushes the
guard out of the way and at the completion
of the cut, the guard springs back over the
cutterhead providing full coverage. If it ever
becomes necessary to adjust the spring tension

of the cutterhead guard, loosen two set screws
(B) and turn screw (C) clockwise to increase or
counterclockwise to decrease the spring ten-
sion. Then retighten the two set screws (B).

WARNING: Before operating jointer, check
guard to make sure it functions properly and
quickly returns to the closed position.
REMOVING, REPLACING
KNIVES
If the knives are removed from the cutterhead
for replacement or regrinding, care must be
used in removing and replacing them as fol-
lows:
1. Disconnect the machine from the power
source.
2. Be extremely careful that your hands do not
come in contact with the cutterhead. Move the
fence to the rear and remove the cutterhead
guard.
3. Using wrench (A) Fig. 19, slightly loosen the
6 locking screws (B) in each knife slot to relieve
stress in the cutterhead by turning them clock-
wise.

4. Loosen screws further and remove the knives
(C) from the cutterhead.
5. When the three knives are removed from
the cutterhead, lower the two knife raising
"jackscrews" with a hex key by turning the
two screws (D) counterclockwise. Then lower
the knife raising "jackscrews" in each of the
two remaining cutterhead slots in the same
manner.
6. When replacing, insert the knife into the slot
in the cutterhead, making certain the bottom
