Installation and Assembly
Tools required for assembly
Forklift or hoist with straps/slings
14mm (or 9/16”) wrench or socket
Cross-point (Phillips) screwdriver
3mm and 5mm hex wrenches (provi ded)
1. Remove any boards or straps that secure
the Jointer to the pallet, and remove
protective wrapping.
2. Use a 14mm (or 9/16”) wrench to remove
the four l ag screws at t he base of the stand
which helped secure the machine to the
pallet. One of these screws is shown in
Figure 1.
The Joint er should be raised
by straps placed arou nd the four lifting rods
(see Figure 2). Do NOT lift the machine
directly beneath the infeed and outfeed
tables, as this can cause misal ig nment of the
tables.
Figure 1
3. Pull the four lifting rods out as far as they
will go and run the straps around the rods
as shown in Figure 2. Using a forklift or
hoist, lift t he machine off the pallet and into
its desired location. When the straps are
removed, push the lift ing rods back in.
4. The Jointer should be locat ed in a dry ar ea,
on a sturdy fl oor, and with suff icient light ing
and ventilation. Leave plenty of space
around the machine for operations and
routine maintenance work.
5. If desired, the Jointer can be further
stabilized by securing it to the floor, using
lag screws through the four holes at the
base of the stand.
The jointer should be
disconnect ed from the power sou rce during
assembly procedures.
6. Exposed m etal areas of the Joi nt er, such as
the table and fence surfaces, have been
factory coated with a protectant. This can be
removed with a soft cloth dampened with
kerosene or mineral spirits. Do not use an
abrasive pad. Do not let solvent contact
plastic or rubber parts as it may damage
them.
Use caution when cleaning
around cut terhead. The knives are ext remely
sharp.

Installing Switch Arm
1. The switch arm was shipped in horizontal
position. Loosen and remove t he four socket
head cap screws and flat washers on the
bracket of the switch ar m (Figure 3) with a
5mm hex wrench. Hol d on t o the switch ar m
while doing this, to prevent the arm from
falling.
2. Place the switch arm in vertical positi on, as
shown in Fi gure 3, and align the f our holes
in the bracket with the four holes in the
jointer stand.
3. Re-insert the four socket head cap screws
with the four flat washers, as shown in
Figure 3.
4. Firmly tighten the four socket head cap
screws with the hex wrench.
Installing Cutterhead Guard
Jointer knives are extremely
sharp. Use caution when working with or
around the cutterh ead.
The cutterhead guard has a spring tension
mechanism which must be properly tensioned
when installing the cutterhead guard on the
machine.
To install the cutterhead guard:
1. Insert a small hex wrench, or similar obj ect,
into the pin on t he guard tension mec hanism
(Figure 4).
2. Twist the hex wrench and pi n clockwise, a s
shown in Figure 5, and hold them there.
3. Lower t he shaft of the guard int o the hole on
the jointer’s rabbeting ledge. See Figure 6.
The guard should be lowered into the hole
far enough that the groove in the guard’s
shaft will mate with the shaft of the locking
handle (Figure 6) .
4. After the guard has been inserted into the
hole, let go of the guard with your left hand the guard will swing toward the fence.
Figure 3
Figure 4
5. Completely tighten the locking handle
(Figure 6), whil e continuing to hold the hex
wrench and pin with your right hand.
6. When the guard is secured, rem ove the hex
wrench from the pin. Slightly loosen the
locking handl e (Figure 6) unti l the pin snaps
back against the r abbeting ledge.
7. Re-t ighten the locki ng handle ( Figure 6).
Figure 5
10
Page 11
The cutterhead guard should now have
sufficient spring tension. Test i t by swingi ng the
guard away from the fenc e and then releasing it.
The guard mu st always have
enough spring tension to cover the unused
part of the cutterhead during the cutting
operation, and to swing back to contact the
fence when the workpiece has cleared the
area.
If more spring tension on the guard is desired,
follow the abov e procedure with this exc eption:
tighten the locking handle without allowing the
pin to snap back to the rabbeting ledge. The
farther cl ockwise the pin i s situated, t he greater
will be the spring tension.
Dust Collection
It is strongly recomm ended that a dust collection
system (not provided) be connected to the
jointer. It will help keep your shop clean, and
reduce the ri sk of heal th problems due to wood
dust. The dust collector should have sufficient
capacity for this size jointer.
Figure 6
Connect the dust collection hose to the 4”
diameter dust por t on the jointer (Fi gure 7) and
secure it with a hose clamp or duct tape.
NOTE: Dryer v ent hose is not acceptabl e for this
purpose.
Grounding Instructions
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.
This mac hine m ust be grounded. I n the event of
a malfuncti on or break down, groundi ng prov i des
a path of least resi stance f or electric current to
reduce the ri sk of el ectri c shock.
Improper connection of the equipmentgrounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equi pment-grounding c onduc tor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded.
Figure 7
(hose and clamp not prov ided)
11
Page 12
Use only three wire extension cords that have
three-prong grounding plugs and three-pole
receptacles that accept the tool’s plug.
Repair or replace a damaged or worn cord
immediately.
Make sure the voltage of your power supply
matches the specif ications on the m otor plate of
the Jointer.
Extens ion co rds
The use of an extension cord is not
recommended f or the PJ882 Joint er. But if one
is necessary, make sure the cord rating is
suitable for the amperage listed on the
machine’s motor plate. An undersized cord will
cause a drop in line volt age resulting in loss of
power and overheating.
Use the chart in Fi gure 8 as a general guide in
choosing the cor rect size cord. If in doubt, use
the next heavi er gauge. The smaller the gauge
number, the heavier the cord.

230 Volt, Single Phase Operation
As receiv ed from the f actory, the single-phase
model of the PJ-882 Jointer i s designed to run
on 230 volt power only.
You may either connect a UL/CSA listed 230V
plug (similiar to the one shown in Figure 9) or
“hard-wire” the machine directly to a control
panel. If hard-wired to a panel, make sure a
disconnect is available for the operator. The
Jointer must comply with all local and national
codes after being wir ed.
If the Joi nter i s to be hard- wired, m ake sure the
fuses have been r emoved or the breakers hav e
been tripped in the circuit to which the Jointer
will be connected. Place a warning placard on
the fuse holder or circuit breaker to prevent it
being turned on while the machine is being
wired.
The Jointer with a 230 volt plug should onl y be
connected to an outlet having the same
configurati on. No adapter is av ailable or should
be used with the 230 volt pl ug.
Three Phase Operation
The three-phase model i s factory wired f or 230
volt, but can be converted to 460 volt if so
desired (see “Co nverti ng From 230 Volt to 460
Volt”).
*based on li miting th e lin e vol tage drop to 5V at 15 0% of th e
rated amp eres.
NR: Not Recommended.

If you are hard- wiri ng the Joi nt er, m ake sure the
fuses have been r emoved or the breakers hav e
been tripped in the circuit to which the Jointer
will be connected, and place a warni ng placard
on the fuse holder or ci rcuit br eaker t o prevent it
being turned on until wir ing is complete.
Converting from 230 Volt to 460 Volt
(Three Phas e Only)
Refer to the diagr am on page 46 for connecting
the motor leads for 460 volt power. If using a
plug, it must be a proper UL/CSA listed plug
suitable f or 460 volt operati on. T he Joi nter m ust
comply with all local and national codes after
being wired.

For accurat e jointing, at least three t hings must
be true:
1. Infeed and outf eed tables must be parall el,
or “coplanar” .
16
Page 17
2. Knives m ust be set i n the c utt erhead so that
P
s
the highest point of thei r arc is level wit h the
the outfeed table.
3. Knives must be parallel with the outfeed
table across the entire length of the knives.
These alignments are explained below.
Setting Tables Parallel
For optimum performance of the jointer, the
infeed and outf eed tables must be parall el frontto-back with eac h other. If they are not paral lel,
the finished workpiece may have a slight taper
across its width or length.
The tables hav e been set parall el at the f actory,
but they should be double-checked by the
operator. Also, as the machine receives use,
this parallel setting should be checked
occasionally and adjusted if necessary.
The following procedure uses a steel straight
edge to set the t ables, which should be accurate
enough for most pur poses.
This procedure demonstrates how to set the
parallelism of the outfeed table; the procedure
for the infeed tabl e wil l be identical.
1. Di sconnect jointer from power source.
2. Remove the cutterhead guar d by loosening
the locking handl e (see Figure 6) an d lifti ng
the guard shaft out of the hol e.
3. Slide the fence assembly back as far as it
will go, or remove it from the machine
entirely.
4. Loosen the locking handle on the outfeed
table (see A, Figure 23). Use the lifting
handle (B, Figure 23) to raise the outfeed
table higher than the cutterhead.
lace a straight edge ac ross the front of the
5.
outfeed tabl e and extending ov er the infeed
table. See Figur e 19.
6. Raise the infeed table until it contacts the
traight edge. To raise the infeed table,
loosen the locki ng handle ( see A, Figure 28)
and lift the adjustment arm (B, Figure 28).
When it contacts the straight edge, tighten
the locking handle (A, Figure 28).
7. The straight edge should lie level across
both tables. Move the straight edge to the
back of the outfeed table, and perf orm the
same test. See Figure 20.
8. If the straight edge does not lie level, the
front or back of the t able must be adjusted
to make the tables paral lel with each other.
Proceed as follows.
Figure 19
Figure 20
17
Page 18
9. Each table has four cam adjustment
devices; two in front and two in back.
NOTE: On the front of the Jointer, the two
outside cams are concealed by the hubs.
You must remove the hub to expose the
cam adjustment dev ice. Remove the socket
head cap screw and flat washer at the
center with a 6mm hex wrench, and loosen
the two setscrews in the hub (Figure 21
shows one of the two set scre w holes). Pull
the hub straight out to expose the cam
adjustment device.
10. At the area of the table where the
adjustment must be made, pry out the cap
(A, Figure 22) fr om the hole.
11. T here are two set screws in the hol e. Insert
a 4mm hex wrench (B, Figure 22) into the
hole and loosen the upper set screw by
turning the hex wrench counterclockwise.
Remove the upper set screw fr om the hole.
12. Loos en the lower set screw (do not rem ove
it) by turning c ounterclockwise with the hex
wrench.
13. Turn the hex nut (C, Fi gur e 22) with a 1-1/4"
wrench. T his adjustment i s sensitive and should be made in small increment s.
NOTE: The rotation is different for left and
right hex nuts; the right hex nut being turned
in Figure 22 will be turned clockwise to raise
that area of the tabl e, or c ounterclockwise to
lower that area of the table. The left hex nut
shown in Fi gure 22 would be rotated i n the
opposite manner.
14. Use the straight edge upon the table and
across the cutterhead to check the
adjustment until the tabl e is parallel wit h the
cutterhead.
15. When the adjustment is satisfactory, with
the tables now parallel to the cutterhead,
tighten the lower set screw with the hex
wrench (B, Figure 22).
16. Insert and tighten the upper set screw.
17. Re-insert the cap (A, Figure 22) to keep
dust and debris out of t he hole.
Setting Knives at Correct Height and
Parallel To Outfeed Table
Figure 21
Figure 22
(back of outfeed table shown)
For accurate jointing, the outfeed table surface
must be level with the kniv es at the hi gh point of
their arc. Al so, the knives must be parall el with
the outf eed table along the enti re length of the
knives.
18
Page 19
When you receive the jointer, the knives have
been pre-set at t he factor y. However, the height
and parallelism of the knives with the outfeed
table should be checked, and any needed
adjustment s made, before put ting the j ointer into
operation.
Proceed as follows:
1. Di sconnect jointer from power source.
2. Place a straight edge upon the outfeed table
and extending over the center of the
cutterhead as shown in Figures 23 and 24.
3. Rotate the cutterhead, using the belt or
pulley, until one k nife is at its highest point.
Do not grab the cutterhead it self to rotate it.
4. Lower the outfeed table until the straight
edge contacts the knif e, as shown in Figure
24. Using the driv e belt, r ock the cutterhead
slightly t o make sure t he apex of the knif e is
contacti ng the str aight edge.
5. Lock the outfeed table at that setting by
tightening t he l oc ki ng handle (A, Figure 23).
Figure 23
The importance of the knives being level with
the outfeed tabl e are shown by these ex amples
of incorrect settings:
If the outfeed table is too high, the finished
surface of the workpiece will be curved. See
Figure 25.
If the outf eed table i s too l ow, the work will have
a gouge, or snipe, at the end of the cut. See
Figure 26.
Figure 24
Figure 25
Figure 26
19
Page 20
Figure 27 illustrates the correct setting of
outfeed table level with the knives. The
workpiece will rest firmly on both tables with no
open space under the finished cut.
The outfeed table has now been locked at a
standard height, l ev el with the arc of t he knives.
NOTE: After the outfeed table has been set at
the correct height, it should not be changed
except for special operations or after replacing
knives.
Further fi ne adjustments will now be achieved by
adjusting the k nives in the cutt erhead. Proceed
as follows.
Figure 27
Jointer knives are extremely
sharp; use cau tion and p roceed slowly wh en
setting them.
6. Lower the infeed table out of the way, by
loosening the l ocking handl e (A, Figure 28)
and pushing down on the adjustment arm
(B, Figure 28).
7. An aluminum knif e setting gauge, shown in
Figure 29, is provi ded with the jointer. If you
require very fine tolerances when setting the
knives, a knife setting gauge with a dial
readout can be purchased (see “Optional
Accessories” on page 32). The provided
aluminum gauge should, however, be
accurate enough for most woodworking
needs.
8. Place the provided knife setting gauge at
the back of the outfeed table (toward the
fence support si de) and extending over the
cutterhead as shown i n Fi gure 29. Place t he
gauge so that the right mark lines up with
the edge of the outfeed t able, as shown.
9. Rotate the cutterhead clockwise (by using
the pulley). If table and knives are set
correctly, the knife will contac t the al umi num
gauge and move the gauge until the left
mark now lines up with the edge of the
outfeed tabl e, as shown in Fi gur e 30.
Figure 28
Figure 29
20
Page 21
10. Plac e the alumi num knife gauge at t he fr ont
of the outfeed table (toward the rabbet
ledge) and repeat the process.
11. This test should be performed on all three
knives in the cutter head, using the provi ded
gauge.
12. If any knife is either too high or too low at
one of its ends to corr ectly move the gauge
as described abov e, then the height and/or
parallelism of that knife in the cutterhead
needs to be adjusted. Proceed as follows.
13. Slightly loosen the five gib screws (see
Figure 31) with an 8mm wrench. (NOTE:
The springs below the knife will cause the
knife to ris e .)
14. Turn the jack screw(s) with a hex wrench;
clockwise to l ower the setting of the knif e i n
the cutterhead, counterclockwise to raise
the setting of the knife.
15. Use the edge of a board to push the knife
back down so that it is fl ush against the j ack
screws. See Figure 32. Tighten the gib
screws only enough to keep the knife in
position in the cutterhead. Do not fully
tighten.
16. Check t he height of t he knif e agai n by usi ng
the gauge at front and back of the outfeed
table. Make further adjustments to the jack
screw(s) as needed.
17. Repeat this process for each of the other
two knives in turn. Do not fully tighten gib
screws, only tighten them enough to keep
the knife in positi on.
18. For best results, knives should be set at
approximately .015" above the cutterhead.
Knife height shoul d not vary more t han .002.003" across the length of the cutterhead. All
three knives must be set at equal height in
the cutterhead and parallel to the outfeed
table across thei r length.
Figure 30
Figure 31
19. Aft er all three kniv es are po sit ioned pr operl y
in the cutterhead and m ade snug, continue
tightening the gib screws. The gib screws
should be tightened in increments, to
prevent any distortion to the cutterhead or
buckling of knives. Begin tightening t he gib
screws a lit tle more on one knif e. Star t with
the center screw and work your way to the
ends. Do not fully tighten yet.
20. Rotate the cutterhead to the other two
knives in turn. Repeat step 20 for each
knife.
Figure 32
21
Page 22
21. The tightening process should continue at
least two more times, each time tightening
the gib screws furt her on all three knives in
turn. On the third time, the gib screws
should all be firml y tight ened.
Before operating the jointer,
make sure all gib screws are firmly
tightened. A loose knife thrown from the
cutterhead can cau se severe or fatal injury.
22. After all knife adjustments are completed,
the guards and fence assembly should be
placed back on the machine before
operating.
Outfeed Table Stop Screws
The stop scre w (B, Figur e 33) limi ts the am ount
of fall of the outfeed t able. The stop screw has
been pre-set at the factory, but if future
adjustment is ever needed, simply loosen the
hex nut (A, Figure 33) and turn the screw (B,
Figure 33) as needed with a 14mm wrench.
When satisf ied, re-ti ghten t he hex nut ( A, Fi gure
33).
The screw (C, Figure 33) limits the rise of the
outfeed table. If adjustment is needed, loosen
the hex nut (D, Figur e 33) and turn the screw (C,
Figure 33) as needed with a 9mm hex wrench.
When satisfi ed, re- tight en the hex nut (D, Figur e
33).
Figure 33
Setting Infeed Table (Depth of Cut)
1. Loosen locking handle (A, Figure 34).
2. Move tabl e adjustment arm (B, Figure 34) t o
raise or lower infeed table to the desired
depth of cut , which is shown on the gauge
via the pointer (C, Fi gur e 34) .
NOTE: Do not exceed 1/8” maximum depth of
cut. For deeper cuts, make several passes.
3. Re-t ighten locking handle (A, Figure 34).
Infeed Table Depth Stop
The knob (Figure 35) controls a depth stop.
When the i nfeed table is lowered, i t will stop at
the 1/8” depth mark.
To further lower the infeed table, such as for
rabbeting operat ions, disengage the depth stop
by pulling out on the k nob, rot ati ng t he knob 90°
and then releasing i t. The i nfeed table can then
be lowered all the way.
To re-engage the depth stop, rotate the knob
90° until the knob snaps back in.

Infeed Table Stop Screws
The stop screws below the infeed table have the
same function as those for the outfeed table.
See “Outfeed Table Stop Screws” for
instructions on adjustment.
Replacing Knives in the Cutterhead
Jointer knives are extremely
sharp. Use caution and p roceed slowly wh en
working with or around the cu t t erhead.
1. Di sconnect jointer from power source.
2. Remove the belt guard so that you can
rotate the cutterhead by turning the motor
pulley or by moving the drive belt. Do not
grab the cutter head itself to rotate it.
3. Remove the old knives by loosening the
square head gib screws with an 8mm
wrench. See Figure 36. The springs in the
cutterhead will raise the knife for easy
removal. Remove knife and gib.
4. Clean the gib and the knif e slot. Sandwich
the new knife and gi b toget her and drop int o
slot. Make sure t he k nife is oriented properly
in the cutterhead, as shown in Figure 36.
Figure 36
IMPORTANT: T o position the knives for rabbet
cuts, take a shop scale with 1/32” graduations
and place it against the end of the cutterhead.
Slide the knif e out until it i s at the 1/ 32” m ark on
the scale; that is, the knife will now be 1/32”
beyond the edge of the cutterhead. The gib
should remai n in normal posit ion, even with the
edge of the cutterhead. See Figure 37. This
adjustment will ensure that the knife clears the
end of the gib and cutterhead, and has good
contact with the workpiece. (See under
“Operation” for further i nformation on rabbeting
procedures.)
5. The height and paral lelism of the k nife in the
slot, both for rabbeting and normal jointer
work, must now be set properly, to ensure
correct operation as well as minimize the
hazard of kic kback. Refer to “S etting Knives
at Correct Height and Parallel to Outfeed
Table” on page 18 for information on
adjustment and tightening procedures for
the knives.
Before starting the jointer,
make sure all gib screws are firmly
tightened. A loose knife thrown from the
cutterhead can cau se severe or fatal injury.
Figure 37

Page 24
Eliminating “Play” in Tables
There are four set screws at the front of the
jointer – two on the outfeed table and t wo on the
infeed table – that will allow you to prevent
“play” in the tables. (Figure 38 shows a set
screw for the outfeed table.)
After a period of use, the copper tip (see item
#27, page 37) which is attached to the end of
the set screw (A, Fi gure 38) may becom e l oose.
Resolve this as follows.
1. Loosen the hex nut (B, Figure 38) with a
14mm wrench.
2. Tight en the set screw (A, F igure 38) with a
5mm hex wrench. Do not over tighten the set
screw, as it may prevent the table from
being raised and l owered easily.
3. Tighten hex nut (B, Figure 38).
4. Repeat for the other set screws as needed.
NOTE: The outfeed table is pre-set at the
factory tighter than the infeed table. If you find
the outf eed table diffi cult t o move with t he lifti ng
handle, loosen the two set screws on the
outfeed tabl e, as j ust described.
Operating Controls
Press the start switch, shown in Figure 39, to
begin rotation of the cutter head. T he stop butt on
is a mushroom style button which i s conveni ent
for "emergency " shut-downs.
After being pushed, the stop button remains
engaged. To re-start the Jointer, twist the stop
button clockwise until it pops back out.
Figure 38
Operation
NOTE: If y ou are inexperienced at jointing, use
scrap pieces of lumber t o c hec k settings and get
the feel of operati ons before att empting regul ar
work.
Stabilize l ong workpieces by using a n assistant ,
or roller stands set level with the outfeed or
infeed table surf ac e.
The fence should be adjusted to create
minimum exposure t o the cutterhead during the
jointing operation.
Check the following before operating the j ointer:
1. Outfeed table must be set level with the hi gh
point of the knives.
2. Fence adjusted for minimum exposure of
cutterhead, and locked at desired angle.
Figure 39
24
Page 25
3. The cutterhead guar d must be in place and
operating proper ly (except when rabbeting) .
4. Infeed table set for desir ed depth of cut.
5. Stand away from the cutterhead and turn
the machine on for a f ew moments. Listen
for any odd noises, rubbi ngs, vi brati ons, etc.
Correct such problems before attempting
operations on the jointer.
6. Carefully check your workpiece for knots,
holes, staples or any foreign material that
might damage knives or pose a risk of
kickback. A lso check the workpiece for gr ain
orientation.
Hand Placement
At the start of the cut, the left hand holds the
workpiece firmly against the infeed table and
fence while the ri ght hand pushes the workpi ece
in a smooth, even motion t oward the cutterhead.
After the c ut is under way, the new surface rests
firmly on the outfeed table. The left hand is
transferred to the outfeed side and presses
down on this part of t he workpiece, at the same
time maintaining flat c ontact with the fence. The
right hand presses the workpiece forward and
before the right hand reaches the cutterhead it
should be moved to the work on the outfeed
table. Never pass hands directly over the
cutterhead.
Surfacing
Always use a hold down or
push block when surfaci ng stock.
Jointing the f ace of stock, or surf acing, i s shown
in Figure 40. Adjust the infeed tabl e for depth of
cut. Cuts of approximately 1/16” at a time are
recommended, as this allows better control over
the material being surfaced. More passes can
then be made to reach the desir ed depth.
Figure 40
Edge Jointing
This is the most common operation for the
jointer. Set fence square with the t able. Depth of
cut should be the m inimum requi red to obtain a
straight edge. Do not make cuts deeper than
1/8" in a single pass. Hol d the best face of the
workpiece firmly against the fence throughout
the feed. See Figure 41.
Figure 41
25
Page 26
Rabbeting
A rabbet cut requires
removal of the guard. Use extreme caution
and keep hands cl ear of cutterhead. Alw ays
re-install guard immediately after rabbeting
operation is completed.
A rabbet is a groove cut along the edge of a
board. See Figure 42. The width and thick ness
of the wood to be rabbeted depends upon the
width and length of the rabbet. Ho wever, never
rabbet a piece of wood less than 12” l ong.
Use push blocks to rabbet cut whenever
possible. The rabbeting capacity is 1/2”.
1. Di sconnect jointer from power source.
2. Set fence for desired width of rabbet .
3. Check width of the rabbet by measuring t he
distance from the end of a knife in the
cutterhead to t he fence. NOTE: The kniv es
must be extended beyond t he cut ter head by
1/32”. (see “Replacing Knives in the
Cutterhead” for this procedure).
Figure 42
4. Re-connect power. It is easier and safer t o
take a series of shallow cuts. Lower the
infeed table 1/32” at a time and make
successive cuts until the desired depth of
rabbet has been obtained. See Figure 42.
Jointing Short or Thin Work
When jointing short or thin work pieces, use a
push block to elim inate all danger to t he hands.
Two push blocks are shipped with your jointer.
You can also mak e your own easily from scrap
material. Ex am ples are shown in Figure 43.
Jointing Warped Surfaces
If the wood to be jointed is cupped or bowed,
place the concave side down, and take light cuts
until the surfac e i s flat.
Avoid forcing such material down against the
table – excessive pressure will spring it while
passing the kniv es, and it will spring back and
remain curv ed aft er the c ut is completed.
Beveling
To cut a bevel, lock the fence at the required
angle and run the work piece acros s the knives
while keeping it firmly against the fence and
tables. Several passes may be necessary to
achieve the desi r ed r esul t.
Figure 43
26
Page 27
Although the fence may be
tilted in or out for a bevel cut, it is
recommended for safety reasons that the
fence be tilted in toward the operator,
making a cradled cut.
Direction of Grain
Avoid feeding work into the jointer against the
grain. Thi s may r esult in c hipped and spl i ntered
edges. See Figure 44. Feed with the grain to
obtain a smooth surfac e, as shown in Figure 45.
Skewing (Shear Cutting)
When edging or facing material such as burl or
birds-eye maple, it is not unusual to deface or
mar the surface being finished. This is caused
by the cutterhead kniv es at tim es cutti ng against
the grain. In order to prevent the defacing or
marring of this type wood, it is necessary to
skew the material being worked so that it
crosses the knives at an angle.
The fence will all ow for this type of cut:
Figure 44
Figure 45
1. Release the fenc e locking handl e (A, Figure
46) and remove the two hex nuts and
washer (B, Figure 46) holding the fence to
the slide bracket. Remove the fence
assembly.
2. Remove the key (C, Figure 46) from the
fence support. If necessary, use a flat head
screwdriv er to pry up one end of the key .
3. Replace the f ence assembly at the desi red
angle across t he cut terhead. See F igur e 47.
Secure the fence to the slide bracket with
the hex nuts and washer (B, Figure 46),
then tighten the fence locking handle (A,
Figure 46).
NOTE: When placing the fence assembly back
into normal position, be sure to first install the
key into its slot.
Figure 46
27
Page 28
Maintenance
t
Disconnect machine from
power source before doing any
maintenance. Failure to comply may cause
serious injury.
The table and fence surfaces must be kept
clean and free of rust for best results. Some
users apply a thin coat of paste wax. Avoid
waxes or protectiv e sprays that contain si licone,
as this can transf er to the workpiece and make it
difficult for later finishes to adhere to the wood.
Another opti on is talcum powder appli ed with a
blackboard eraser rubbed in vigorously once a
week; this will fill casting pores and form a
moisture barrier. This method provides a table
top that is slick and all ows rust rings to be easi ly
wiped from the surface. Important also is the
fact that talcum powder will not stain wood or
mar finishes as some ot her pr oduc ts.
Gum and pitch which collect on the knives
cause excessiv e friction as the work cont inues,
resulting in overheating of the knives, less
efficient cutting, and consequent reduc tion in t he
life of t he kniv es. Use ov en cl eaner or “gum and
pitch remover” to wipe this off the knives. Use caution when working around knives!
Figure 47
(skewing t he fence)
The bearings in the cutterhead are sealed for life
and do not require lubri c ation.
The fence assem bly should sli de easil y ov er t he
slide bracket . Keep the slide bracket, shown in
Figure 48, l ubricated with a good quality multipurpose grease. Do not get gr ease on the drive
belt.
Do not place he avy objec ts on the tables, or use
the jointer as a storage table.
Sharpening Knives
Knives should be kept sharp. Thi s will cont ribut e
to better stock finish, longer machine life, and
safer operation.
A jointer knife hone provides a simple way to
sharpen kniv es. Hones are avail able from many
woodworking supply stores. Carefully read any
instructions that accompany the hone.
Use caution and proceed
slowly when sharpening knives. Disconnect
jointer from power source, and wear
approved eye protect io n.
When finished sharpening knives, they should
be re-set level with and parallel to the outfeed
able. See “Setti ng Kniv es at Corr ect Hei ght and
Parallel to Outfeed Table” on page 18.
Figure 48
28
Page 29
Knives can usually be whetted several tim es in
the cutterhead bef ore hav ing to be rem oved and
re-ground.
TIP: If the joint er is used f requently, keeping a
spare set of knives on hand is recommended.
Extra knives (stock no. 6296046, set of 3) may
be obtained from your distributor, or by calling
customer service at 1-800-274-6848.
Cutterhead Repairs
The entire cutterhead assembly may be
removed from the Jointer for bearing
replacement or other m aintenance procedures.
Use caution when working around sharp knives.
To remove the cutterhead, proceed as follows:
1. Di sconnect jointer from power source.
2. Remove fence assembly from jointer.
3. Lower bot h infeed and outf eed table.
4. Remove belt guard, and remove drive belt
from around cutter head pulley.
Figure 49
5. Remove knives from cutterhead.
6. Remove rabbeting ledge by loosening and
removing the two hex cap screws and
washers which secure it to the infeed table.
7. Loosen the two bolts that secure the
cutterhead to t he base; the se are accessed
through the gap below the j oint er base. See
Figures 49 and 50. Pl ace a wrench on each
of the bolt heads and turn each bol t until t he
cutterhead i s loosened.
8. Lift cutterhead strai ght up from base.
9. Remove pulley and both bearing housings.
IMPORTANT:
this should be done by qualified service
personnel. Bearings are press fitted and must
be removed or installed with an “arbor press”.
10. To re-install cutterhead, reverse the above
procedure. Before re-installing, make sure
the machine's curved seats of the base
casting are free of dirt, dust or grease, to
help ensure a tight fi t.
11. After the cutterhead has been installed,
check the infeed and outf eed table settings
in relationship to the cutterhead.
TIP: You may wish to keep an ext ra cutterhead
on hand to maintain shop produc tivity.
If the bearings need replacem ent,

stop-button is disengaged. See page
24.
When jointer overloads on the circuit
breaker built into the motor starter, it
takes time for the machine to cool
down before restar t. Allow unit to
adequately cool bef ore attempting
restart. If pr oblem persists, check
amp setting on the mot or start er
inside the electrical enclosure.
One cause of overl oading trips which
are not electric al in nature is too
heavy a cut. The solution is to take a
lighter cut. If too deep a c ut is not t he
problem, then chec k the amp setting
on the overload rel ay . Match the full
load amps on the motor as noted on
the mo tor pl ate. If amp s etti ng is
correct then ther e is probably a loose
electric al lead. Check amp setting on
motor starter.
Building circuit breaker trips or fuse
blows.
Switch or motor f ailur e ( how to
distinguish).
Motor overheat ed.
Motor failure.
Verify that jointer is on a circuit of
correct size. If circuit size is correct,
there is probabl y a loose el ectr ic al
lead. Check amp setting on motor
starter.
If you have access to a voltmeter, you
can separate a starter f ailure from a
motor fai lu re by fi r st, verifying
incoming voltage at 220+/-20 and
second, checking the voltage
between starter and motor at 220+/-
20. If incoming voltage is incorrect,
you have a power supply problem. If
voltage between start er and m otor is
incorrect, y ou hav e a starter pr oblem.
If voltage bet ween start er and m otor
is correct, you hav e a motor pr oblem .
Clean motor of dust or debri s to allow
proper air circulation. Allow motor to
cool down before r estar ting.
If electri c mot or i s suspect, you have
two options: Have a qualified
electrician test the motor for function
or remove the motor and take it t o a
qualified elec tric motor repair shop
and have it tested.
