10
Installing Dust Chute
Attach the dust chute (Fig. 10) to the stand
with four screws and four flat washers,
through the pre-tapped holes in the stand.
Electrical Connections
Electrical connections
must be made by a qualified electrician
in compliance with all relevant codes.
This machine must be properly
grounded to help prevent electrical
shock and possible fatal injury.
Model JWJ-8CS: Remove the cover of the
switch box (A, Fig. 11) and mount the box
to the right side of the stand using the two
screws provided. Insert the motor leads
through the hole in the stand as shown, and
insert a grommet (B, Fig. 11).
Consult the wiring diagram inside the
switch box cover. The diagram is also on
page 30 of this manual.
The JWJ-8CS and JWJ-8HH jointers are
rated at 230V, single phase only. Confirm
that the power at the source is compatible
with the jointer before inserting plug into the
outlet. The jointer is designed to be used
with a plug and outlet similar to that shown
in Fig. 12.
Figure 9
Figure 10
Important: Make certain the receptacle
in question is properly grounded. If you
are not sure, have a registered
electrician check the receptacle.
Extension Cords
Make sure the rating of the extension cord
is suitable for the amperage listed on the
machine’s motor plate. An undersize cord
will cause a drop in line voltage resulting in
loss of power and overheating.
Use the chart in Figure 13 as a general
guide in choosing the correct size cord. If in
doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the
cord.

Leveling Outfeed Table to Cutterhead Knives
Machine should be
disconnected from power source at this
time! Cutterhead blades are extremely
sharp! Use caution when hands are near
the cutterhead!
For most jointing operations, the surface of
the outfeed table must be level with the
knife tips of the cutterhead at their highest
point of revolution. The knife tips must
project equally from the cutterhead.
The outfeed table and cutterhead are
adjusted at the factory and should not
require adjustment.
1. On the JWJ-8CS Jointer, carefully
number each blade with a magic
marker to make them easier to
differentiate.
2. Rotate the cutterhead by turning the
cutterhead pulley and determine the 12
o’clock position of knife number one (or
a knife insert on the JWJ-8HH model).
The 12 o’clock position is the highest
point a blade will reach in the cutting
arc.
3. Loosen table lock screw (A, Fig. 17)
and raise the outfeed table to the
height of blade number one by turning
handwheel (B, Fig. 17). Counterclockwise will cause the outfeed table
to raise. Clockwise will cause the
outfeed table to lower.Set a straight
edge (C, Fig. 17) on the outfeed table
and across the cutterhead.
Figure 16
Figure 17
4. Position of the table and straight edge
should look like Figure 18. Use care
when handling the straight edge near
the blades so as not to damage them.
5. When the outfeed table and blade
number one (or knife insert) are the
same height, tighten table lock screw.
After the outfeed table has been set,
the JWJ-8HH will need no further
adjustments to the cutterhead – skip
steps 6 through 9 below. The JWJ-8CS
must have its knives parallel with the
outfeed table. Proceed as follows:
6. Bring the straight edge forward to the
front of the outfeed table and confirm
that blade number one is at the same
height at the front of the table as it is at
the back of the table.
13
Figure 18
Figure 19
7. If blade is higher or lower at one point,
slightly loosen five screws (A, Fig. 19)
by turning clockwise as viewed from
the infeed table.
8. Place the knife setting gauge (B, Fig.
19) on the cutterhead over the blade.
Continue loosening the five screws until
the springs push the knife up into
contact with the gauge. Alternately
tighten the five screws to hold each
blade in place.
9. Repeat this process with blades two
and three. The outfeed table and
cutterhead knives are correctly
adjusted when all three blades are
parallel to the outfeed table and all
three blades are set at the same height
in the cutterhead.
After the outfeed table has been set at the
correct height, do not change it except for
special operations or after replacing the
knives.
If the outfeed table is set too high, a curved
finished surface results. (Fig. 20)
If the outfeed table is set too low, gouging
results at the end of the cut. (Fig. 21)
Figure 20
Figure 21
Figure 22 illustrates the outfeed table at the
correct height.
Removing and Replacing Knives (JWJ-8CS only)
Disconnect the machine
from the power source before making
any adjustment or repair. All knife lock
bolts must be firmly tightened or risk
ejection of the knife(s) and lock bar from
the cutterhead! Failure to comply may
cause serious injury!
1. Disconnect machine from power
source.
2. Remove blade guard by loosening set
screw (A, Fig. 23) and lifting up on
blade guard. Caution: blades are
sharp! Use great care when hands
are around blade area!
3. Loosen the five lock screws (Fig. 24).
Note: Loosen screws by turning in a
clockwise direction as viewed from the
infeed table. Carefully remove the knife
(A, Fig. 25), and the lock bar with
screws (B, Fig. 25). Repeat for the
other two blades.

4. Before assembly, clean all parts
thoroughly and clear cutterhead knife
slots of any dust or debris.
5. Insert knife into the cutterhead channel
making sure it faces the proper
direction.
6. Insert lock bar and screws and tighten
to hold in place. Blades are set at the
proper height when the top of the blade
is 1/16" above the cutterhead.
7. Repeat for other two blades.
8. To set the knives to the outfeed table
and to the same height in the
cutterhead, see section titled “Leveling
Outfeed Table to Cutterhead Knives”
found on page 12 of this manual.
Replacing or Rotating Knife Inserts (JWJ-8HH only)
The knife inserts on the model JWJ-8HH
Jointer are four-sided. When dull, simply
remove each insert, rotate it 90° for a fresh
edge, and re-install it.
Use the two provided star point
screwdrivers to remove the knife insert
screw. See Figure 26. Use one of the
screwdrivers to help hold the cutterhead in
position, and the other to remove the
screw. 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 that you can keep track of the
rotations.
Figure 24
Figure 25
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.
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.

Infeed Table Depth Stop
Referring to Figure 26a:
The infeed table travel limiter located on the
back of the table sets the upper and lower
range for the infeed table height adjustment
and should not require any adjustments.
The infeed table depth stop (A) limits the
depth of a cut (set by adjusting the infeed
table handwheel) to a maximum depth of
1/8”. For normal operations, the depth of
cut should never exceed 1/8", except for
rabbeting operations.
If a rabbeting operation is desired:
1. Lower the infeed table to 1/8", which
will cause the depth stop limiter to
engage.
2. Loosen the lock handle (B) and pull out
on the stop handle (C).
3. Continue lowering the table to the
desired depth of cut.
Important: Never override the depth stop
limiter unless performing rabbeting
operations.
Figure 26a
Gib Adjustment
After a period of use, the gibs may become
loose and need adjusting:
1. Loosen three lock nuts (A, Fig. 27) and
gib lock screw (B, Fig. 27)
2. Tighten each set screw 1/4 turn starting
at the bottom and working up. If a 1/4
turn does not remove all play, take
another 1/4 turn. Repeat a 1/4 turn at a
time for all three set screws until play is
removed.
3. Tighten lock screw (B, Fig. 27) and lock
nuts (A, Fig. 27).
Operation
Keep all guards in place
and in adjustment at all times during the
cutting procedure! Keep hands away
from the cutterhead! Do not pass hands
directly over the cutterhead! The use of
push sticks and/or handle pads are
highly recommended when using the
jointer! Failure to comply may cause
serious injury!
Figure 27
Jointing cuts or edge jointing are made to
square an edge of a workpiece. The
workpiece is positioned on the jointer with
the narrow edge of the workpiece on the
16
infeed table and the major flat surface of
the workpiece against the fence (Fig. 28).
Planing cuts are similar. The major surface
of the workpiece is placed on the table with
the narrow edge of the workpiece against
the fence (Fig. 29).
For jointing and planing cuts pressure is
directed three ways; into the fence to
ensure a square cut, forward to advance
the stock, and downward to avoid chatter
and vibration.
For jointing when the material is higher than
the fence, the left hand applies pressure
into the fence and down toward the table
while the right hand pushes forward from
behind. Be sure to keep the right hand high
up on the material. (Fig. 28)
For jointing material that is lower than the
fence, use push sticks to protect the hands.
For planing, use handle pads. (Fig. 29)
Never place the right hand on the
trailing edge of the material. Hand
placement on the trailing edge of the
material may cause the hand to come
into contact with the blade.
Feed work from right to left at a steady,
moderate speed. If you feed the material
too slowly, the wood will burn in places. If
you feed the material too quickly, ridges will
appear in the finished surface.
Jointing Warped Material
If the work to be jointed is cupped or
warped, take light, repetitive cuts until the
surface is flat. Forcing the material flat
against the table will still leave a warped
piece after the cuts have been made.
Figure 28
Figure 29
Never joint any material
shorter than eight inches! The material
may tip into the jointer’s throat and be
kicked back! Avoid jointing thin material
which could become jammed under the
fence or blade guard! Failure to comply
may cause serious injury!
Direction of Grain
Feed the material with the grain to avoid
tearout (Fig. 30). If the direction of the
grain changes somewhere in the board, try
reducing depth of cut and slow the feed
speed down to avoid tearout. If results still
aren’t satisfactory, turn the material around
and try feeding through the other way.
Figure 30
17
Bevel Cut
To cut a bevel, lock the fence at the desired
angle and run the material through,
pressing the work firmly against the fence
and tables (Fig. 31). Several passes may
be necessary for the desired result.
Taper Cut
Taper cuts require the
removal of the cutterhead guard. Use
extreme caution when making taper cuts
and replace the guard immediately
completion! Failure to comply may
cause serious injury!
One of the most useful jointer operations is
cutting an edge to a taper. This method
can be used on a wide variety of work;
tapered legs of furniture is a common
example.
Instead of laying the piece down on the
infeed table, lower the forward end of the
work onto the outfeed table. Use caution,
however, as the piece will span the knives,
and they will take a “bite” from the work
with a tendency to kick back unless the
piece is held firmly. Push the work forward
as in ordinary jointing. The effect is to plane
off all the stock in front of the knives to an
increasing depth, leaving a tapered surface.
after
Figure 31
The ridge left by the knives when starting
the taper may be removed by taking a very
light cut in the regular jointing procedure,
with the infeed table raised to its normal
position.
Practice is required in this operation.
Beginners are advised to make trial cuts
with scrap material.
Rabbet Cut
Rabbeting requires the
removal of the cutterhead guard. Use
extreme caution when making rabbeting
cuts and replace the guard immediately
after completion!
cause serious injury!
Note: Rabbet cuts are not applicable with
the Model JWJ-8HH Jointer with helical
head.
1. Adjust the fence so that the distance
between the end of the knives and
fence is equal to the width of the rabbet
(Fig. 32).
Failure to comply may
Figure 32
2. Lower the infeed table an amount equal to the depth
of the rabbet. If the rabbet is quite deep, it may be
necessary to cut in two or more passes.
3. In that event, the table is lowered an amount equal
to about half the depth of the rabbet for the first
pass, then lowered again to proper depth to
complete the cut.

Maintenance
Lubrication
1. Use a good grade of light grease on the
steel adjusting screws located in the raising
and lowering mechanisms of the work
tables.
2. Occasionally, apply a few drops of light
machine oil to the gibs. This permits the
tables to slide freely.
3. The cutterhead ball bearings are lifetime
lubricated and need no further care.
7. Take the same amount of passes for all
three blades.
When the blades have been sharpened, if they
still are not cutting efficiently, trying to touch up
the blades further will only cause the formation
of a second beveled edge. When this starts to
happen, it is time to replace blades with another
set.
It is recommended to keep a second set of
blades on hand so that they may be installed
while the first set is being professionally
sharpened.
Cutterhead Removal
Blade Care
Blades are extremely sharp!
Use caution when cleaning or changing.
Failure to comply may cause serious injury!
When gum and pitch collect on the blades,
carefully remove with a strong solvent. Failure
to remove gum and pitch build-up may result in
excessive friction and overheating.
Sharpening Knives (JWJ-8CS only)
When blades become dull, touch up blades.
1. Disconnect the machine from the power
source.
2. Remove the fence, blade guard and belt
cover.
3. To protect the infeed table from scratches,
partially cover the sharpening stone with
paper. (Fig. 33)
Blades in the cutterhead are
sharp! Use extreme caution when handling
the removal of the cutterhead. Failure to
comply may cause serious injury!
The entire cutterhead assembly may be
removed for cleaning or for bearing and blade
replacement. Some woodworkers keep a spare
cutterhead with replacement blades should the
original cutterhead have to be repaired.
To remove the cutterhead (including bearings,
studs, and housing) from the base casting:
1. Disconnect the machine from the power
source.
2. Remove the fence assembly, cutterhead
guard, and belt guard.
3. Remove the v-belt from the cutterhead
pulley.
4. Loosen set screw (A, Fig. 34) using a hex
wrench and remove the cutterhead pulley
(B, Fig. 34) and key (C, Fig. 34).
Figure 33
4. Lay the stone on the infeed table.
5. Lower the infeed table and turn the
cutterhead by turning the cutterhead pulley.
The infeed table height is set properly when
the stone’s surface is flush with the knife
bevel.
6. Keep the cutterhead from rotating by
grasping the cutterhead pulley while sliding
the stone back and forth across the table.
Figure 34
5. Unscrew hex cap screw (D, Fig. 34) with
lock washer (E, Fig. 34) from bearing
housing.
6. Lift assembly straight up.
19
7. Before replacing the cutterhead back into
the casting, thoroughly clean the “saddle”
and the bearing housings of saw dust and
grease so that they seat properly.
8. To re-install the cutterhead, reverse the
above steps.
