Warning
Read the manual. Read, understand, and follow the safety instructions found in this manual. Know the
limitations and hazards in using the model PJ1696 Jointer. Decals are placed on each machine as reminders
of good safety practice.
Installation. If mounting machine to the floor, use high quality anchor bolts through the mounting holes on the
base. If using a mobile base, be sure to lock the wheels.
Location. Use extra care in the location of the jointer in the shop. Place the machine so that potential
kickback area is not in line with aisles, doorways, wash stations, or other work areas.
Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground lead is
included in the incoming electrical service. If a cord and plug are used, make certain the grounding lug
connects to a suitable ground. Follow the grounding procedure indicated in the National Electric Code.
Eye safety. Always wear approved safety goggles, glasses, or a face shield when operating this machine.
(Note: common eyeglasses are only impact-resistant, they are not safety glasses.)
Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll up
sleeves above the elbows. Remove all loose clothing and confine long hair. Protective type footwear should
be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA Regulations,
use hearing protective devices. Do not wear gloves.
Guards. Be sure machine guards are in place and in good working order. Use them at all times on operations
where they can be used. If a guard must be removed for any operation, make sure it is replaced immediately
following completion of that operation.
Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other liquids
to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material and tools
before starting to cut. Make certain the work area is well lighted and that a proper exhaust system is used to
minimize dust. Powermatic recommends the use of anti-skid floor strips on the floor area where the operator
normally stands and that each machine's work area be marked off. Provide adequate work space around the
machine.
Disconnect machine before performing any service or maintenance. A machine under repair should be RED
TAGGED to show it should not be used until the
maintenance is complete.
Housekeeping. Before turning on machine, remove
all extra equipment such as keys, wrenches, scrap,
stock, and cleaning rags away from the machine.
Power on. On machines equipped with a manual
starter make sure the starter is in "OFF" position
before connecting power to machine.
Three inch rule. When working a piece of wood on
the jointer, follow the 3 inch radius rule. The hands
must never be closer than 3 inches to the cutterhead.
See Figure 1.
Always use a hold-down or push block when
surfacing stock less than 12" inches long, or 3 inches
wide, or 3 inches thick.
Do not perform jointing operations on material shorter than 8", narrower than 3/4" or less than 1/4" thick.
Depth of cut. Do not make cuts deeper than 3/4" when rabbeting. On other cuts such as edging, surfacing,
etc., depth of cut should not be over 1/16" to avoid overloading the machine and to minimize chance of
kickback.
Avoid tip-in. Never apply pressure to stock directly over the cutterhead. This may result in the stock tipping
into the cutterhead along with the operator's fingers. Follow the 3 inch rule. Position hands away from extreme
ends of stock, and push through with a smooth, even motion. Never back workpiece toward the infeed table.

Avoid Kickback. "Pull-out" and the danger of kicked back stock can occur when the work piece has knots,
holes, or foreign materials such as nails. It can also occur when the stock is fed against the grain on the
jointer. The grain must run in the same direction you are cutting. Before attempting to joint, or plane, each
work piece must be carefully examined for stock condition and grain orientation.
NOTE: At certain times it may be necessary to plane
against the grain when working with a swirl grain
wood or burls. With this type work the operator must
use a lesser depth of cut and a slow rate of feed.
Hand safety. It is good practice to move the hands in
an alternate motion from back to front as the work
continues through the cut. Never pass the hands
directly over the cutter knife. As one hand
approaches the knives remove it from the stock in an
arc motion and place it back on the stock in a position
beyond the cutter knife (Figure 2). NOTE: At all times
hold the stock firmly.
Misuse. Do not use this jointer for other than its
intended use. If used for other purposes, Powermatic
disclaims any real or implied warranty and holds itself harmless for any injury or damage which may result from
that use. Do not equip or use this jointer with a motor larger than 7-1/2 Horsepower at 5,200 R.P.M. Use of a
larger horsepower motor or higher cutterhead speed voids the warranty and Powermatic holds itself harmless
for any injury which may result.
If you are not thoroughly familiar with the operation of jointers, obtain advice from your supervisor, instructor or
other qualified person.
Drugs, alcohol, medication. Do not operate tool while under the influence of drugs, alcohol, or any
medication.
Health hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
•
•
•
Lead from lead-based paint.
Crystalline silica from bricks and cement and other masonry products.
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment, such as
those dust masks that are specifically designed to filter out microscopic particles.

Receiving the Jointer
Carefully unpack the jointer and all loose items
from the wood crate and inspect for damage. Any
damage should be reported to your distributor and
shipping agent immediately. Before proceeding
further, read your manual thoroughly to familiarize
yourself
with
proper
assembly,
set-up,
maintenance, safety and operating procedures.
Exposed metal parts such as the table and fence
have been given a protective coating at the factory.
This should be removed with a soft cloth moistened
with a solvent (such as kerosene). Do not use
acetone, gasoline or lacquer thinner for this
purpose. Do not use an abrasive pad. After
cleaning, it is recommended that you cover all
unpainted surfaces with a good quality paste wax.

Figure 7
Figure 9
Dust Hood
Electrical Connection
Mount the dust hood (C, Figure 8), to the left side
of the jointer using the seven 1/4-20 x 1/2 screws
(D, Figure 8) provided on the machine. Before
mounting the dust hood, make sure the hole in the
base is covered by the dust chute cover (shown in
Figure 5).
Electrical connections must
be made by a qualified electrician. The machine
must be properly grounded to help avoid
electric shock and possible death.
It is recommended a dust collection system of
appropriate size (at least 800 CFM) be connected
to the dust outlet via a 6" diameter hose.
IMPORTANT:
Make
sure
the
electrical
characteristics are the same between the motor
nameplate and the power source, and make sure
the circuit on which the jointer will be used is
properly fused and that the wire size is correct.
It is recommended that the jointer when operated
at 230 volts, be connected to a dedicated,
minimum 40 amp circuit with a 40 amp circuit
breaker or time delay fuse. When operated at 460
volts, connect the jointer to a dedicated, minimum
20 amp circuit with 20 amp circuit breaker or time
delay fuse. Local codes take precedence over
recommendations.
1. Connect wires from the power source to the
motor junction box. Refer to diagram inside the
motor junction box cover (a similar diagram
appears at the back of this manual). The green
wire (ground) must be properly grounded.
Figure 8
2. After wiring is complete, turn motor on
momentarily to check for proper direction of
rotation (cutterhead should rotate toward
infeed table). If rotation is in the wrong
direction, disconnect machine and switch any
two of the hot leads. Reconnect power and
confirm proper rotation.
Start/Stop Switch
The arm (E, Figure 9) on which the pushbutton
switch is located is shipped in the down position.
The screws (F, Figure 9) should be loosened with a
10mm hex wrench and the arm pivoted to upright
position. Re-tighten screws.
3. Run the machine without cutting for a short
time to check that all powered functions are
operating properly.
460V Conversion
The Jointer is pre-wired for 230 volt operation. If
460 volt operation is required, proceed as follows:
1. Re-connect the motor leads according to the
wiring diagram.
10
Download from Www.Somanuals.com. All Manuals Search And Download.
2. Replace the installed magnetic switch with the
switch rated for 460V operation (stock no.
PJ1696-205D; separate purchase).
3. Change the dial on the overload relay to the
appropriate setting for 460V operation.
4. Check for proper direction of rotation
(cutterhead should rotate toward infeed table).
If rotation is in the wrong direction, disconnect
machine and switch any two of the hot leads.
Reconnect power and confirm proper rotation.
Adjustments
Tools required

Replacing Knife Inserts
Drive Belt
The cutterhead on the PJ1696 is a solid steel
helical insert design with 56 two-sided standard
knives, and two rabbet knives on the outboard end
of the cutterhead. Replacing knives is a simple
process, and they will seat themselves properly
without having to be set with a knife gauge.
Remove the three crown nuts and washers (A,
Figure 10) on the belt cover with a 17mm wrench,
and remove the cover. Use a 19mm wrench to
adjust the nuts in the motor support (B, Figure 11).
Raise or lower motor support to obtain proper
tension, then re-tighten nuts.
After a period of use, dull knives should be flipped
over, replaced or re-ground. To change a knife:
NOTE: Proper tension will be achieved when there
is a small amount of deflection in the belt when
using moderate finger pressure. See Figure 12.
1. Loosen the gib screw (C, Figure 13) and
remove the knife (D, Figure 13) from the slot.
2. Flip the knife 180 degrees and re-insert it, then
tighten the gib screw (C, Figure 13). To ensure
optimal cutting, all knives in the cutterhead
should be flipped at the same time.
Tighten gib screws firmly.
Loose gib screws can result in knives being
thrown out of the cutterhead, causing severe
damage to the machine and possible serious or
fatal injury to the operator or bystanders.
Figure 10
Figure 13
Setting Outfeed Table
For accurate work in most jointing operations, the
outfeed table must be exactly level with the knives
at their highest point of revolution.
Figure 11
1. Raise the outfeed table to its highest point,
and place a straight edge across it.
11
Download from Www.Somanuals.com. All Manuals Search And Download.
2. Turn the cutterhead until one row of knives is
at its highest point.
3. Lower the outfeed table until the straight edge
contacts a knife. Rock the cutterhead slightly
to make sure the apex of the knife is
contacting the straight edge. Lock the outfeed
table at that setting.
After the outfeed table has been set at the correct
height, it should not be changed except for special
operations or after replacing knives.
Examples of incorrect settings:
Figure 16
If the outfeed table is too high, the finished surface
of the workpiece will be curved, shown in Figure
14.
Table Raising Limit Blocks
Refer to Figure 17.
A limit block, shown in Figure 17, is mounted to the
rear of each table. It sets the maximum height the
tables can be raised, and is pre-set at the factory. If
adjustment is ever needed, loosen the hex nut (E)
and turn the screw (F) as needed. Retighten hex
nut (E).
Figure 14
If the outfeed table is too low, the work will be
gouged at the end of the cut, shown in Figure 15.
Figure 17
Infeed Table Adjustment
Refer to Figure 18.
Loosen lock lever (A) and move table adjustment
arm (B) to raise or lower infeed table. Gauge (C)
shows the distance of travel. Re-tighten lock lever
(A).
Figure 15
As a final check of the outfeed table adjustment,
run a piece of wood slowly over the knives for 6 to
8 inches; it should rest firmly on both tables, as
shown in Figure 16, with no open space under the
finished cut.

Operating Instruction
NOTE: If you are inexperienced at jointing, use
scrap pieces of lumber to check settings and get
the feel of operations before attempting regular
work.
Always use guard and keep
hands away from cutterhead. Make sure all
knives or knife inserts are secured in the
cutterhead. Verify tightness (re-torque) of each
insert on the helical head before operating.
Hand Placement
Figure 18
At the start of the cut, the left hand holds the work
firmly against the infeed table and fence while the
right hand pushes the work toward the knives.
After the cut is under way, the new surface rests
firmly on the outfeed table. The left hand should
press down on this part, at the same time
maintaining flat contact with the fence. The right
hand presses the work forward and before the right
hand reaches the cutterhead it should be moved to
the work on the outfeed table. FOLLOW THE 3
INCH RULE. NEVER PASS HANDS DIRECTLY
OVER THE CUTTERHEAD.
Edge Jointing
This is the most common operation for the jointer.
Set guide fence square with the table. Depth of cut
should be the minimum required to obtain a
straight edge. Do not make cuts deeper than 1/8"
in a single pass. Hold the best face of the piece
firmly against the fence throughout the feed. See
Figure 20.
Figure 19
Fence Adjustments
Refer to Figure 19.
The fence (A) tilts backward and forward 45
degrees. It contains a 90-degree stop (B) and a 45-
degree stop (C). The stops should be checked for
accuracy with a square or protractor against the
fence, and adjusted if necessary.
To tilt the fence forward, loosen the lock lever (D)
and tilt the fence using the handle (E). Re-tighten
lock lever (D).
To tilt the fence backward, loosen the lock screw
(D), pivot the stop block (F) out of the way, and tilt
the fence using the handle (E). Re-tighten lock
screw (D).
To move the fence forward or backward across the
table, loosen lock screw (G), then turn knob (H).
When desired position is reached, re-tighten lock
screw (G) securely.
Figure 20
Surfacing
Jointing the face of stock, or surfacing, is shown in
Figure 21. Adjust the infeed table 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 desired depth.
13
Download from Www.Somanuals.com. All Manuals Search And Download.
See Figure 22. NOTE: It is easier and safer to
take a series of shallow cuts.
Always use a hold down or
push block when surfacing short stock or stock
less than 3 inches thick.
Jointing Warped Surfaces
If the wood to be jointed is dished or warped, take
light cuts until the surface is flat. Avoid forcing
such material down against the table; excessive
pressure will spring it while passing the knives, and
it will spring back and remain curved after the cut is
completed.
Jointing Short or Thin Work
When jointing short or thin pieces, use a push
block to eliminate all danger to the hands. Two
push blocks are shipped with your jointer. You can
also make your own easily from scrap material.
Two types are shown in Figure 23.
Figure 21
Rabbeting
A rabbet cut requires removal
of the cutter guard. Use extreme caution and
keep hands clear of cutterhead. Always replace
guard immediately after rabbeting operation is
completed.
A rabbet is a groove cut along the edge of a board.
See Figure 22. The width and thickness of the
wood to be rabbeted depends upon the width and
length of the rabbet. However, never rabbet a
piece of wood less than 12” long.
Figure 23
Direction of Grain
Avoid feeding work into the jointer against the
grain. This will result in chipped and splintered
edges. See Figure 24. Feed with the grain to
obtain a smooth surface, as shown in Figure 25.
Figure 22
Use push blocks to rabbet cut whenever possible.
The rabbeting capacity is 3/4”.
Figure 24
1. Disconnect machine from power source.
5. Set fence for desired width of rabbet.
6. Check width of the rabbet by measuring the
distance from end of knife in the cutterhead to
the fence.
7. Reconnect power. Lower infeed table 1/32” at
a time and make successive cuts until the
desired depth of rabbet has been obtained.
Figure 25

To remove the cutterhead:
Beveling
1. Disconnect machine from power source.
2. Lower infeed and outfeed tables.
3. Remove rabbeting ledge and fence.
4. Remove belts.
To cut a bevel, lock the fence at the required angle
and run the work across the knives while keeping it
firmly against the fence and tables. Several
passes may be necessary to achieve the desired
result.
5. Loosen the two bolts that hold the cutterhead
to the bed – these are accessed from the
underside of the bearing blocks as shown in
Figure 26.
Taper Cuts
One of the most useful jointer operations is cutting
an edge to a taper. The method can be used on a
wide variety of work. Tapered legs of furniture are
a common example.
Before removing cutterhead,
wrap it with cloths to prevent personal injury.
Instead of laying the piece on the infeed table,
lower the forward end of the work onto the outfeed
table.
Do this very carefully, 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
firmly held. Now push the work forward as in
ordinary jointing.
The effect is to plane off all the stock in front of the
knives to increase depth, leaving a tapered
surface.The ridge left by the knives when starting
the taper may be removed by taking a very light cut
according to the regular method for jointing, with
the infeed table raised to its usual position.
Practice is required in taper operations, and the
beginner is advised to make trial cuts on waste
material. Taper cuts over part of the length and a
number of other special operations can easily be
done as the operator gains experience.
Figure 26
6. Slide the cutterhead out the rabbeting side.
7. Loosen lock screw (A, Figure 27) and remove
pulley (B, Figure 27) and key (C, Figure 27).
8. Take down screws (D, Figure 27) on both
sides and remove bearing cap plates (E,
Figure 27).
Maintenance
Disconnect machine from
power source before performing maintenance.
Check all screws and fasteners occasionally and
keep them tightened securely.
The table and fence surfaces must be kept clean
and free of rust for best results. Some users prefer
a paste wax coating. Aerosol protectants are also
available at hardware and tool stores.
Lubrication
Use a high grade light grease on the steel
adjusting screws for the raising and lowering
mechanisms of the infeed and outfeed work tables.
Figure 27
The cutterhead runs in two single-row sealed and
shielded ball bearings, which are pre-lubricated for
life - no maintenance is necessary.
IMPORTANT: If the bearings (G, Figure 27) need
replacement, Powermatic strongly recommends
this be done by qualified service personnel. The
bearings are press fitted and must be removed with
an arbor press.
Cutterhead Repairs
The entire cutterhead assembly may be removed
for bearing replacement or other cutterhead
maintenance procedures.

9. To re-install the cutterhead, reverse the above
procedure. NOTE: Before reinstalling, make
sure the machine's curved seats of the base
casting are free of dirt, dust or grease, to help
ensure a tight fit.
An advantage of the helical style cutterhead is that
if knife inserts develop nicks, these inserts can be
individually flipped or replaced without the need to
disturb the other inserts.
If the jointer is used often, keeping a spare set of
blade inserts on hand is recommended.
Blade Inserts
Gum and Pitch which collect on the inserts cause
excessive friction as the work continues, resulting
in overheating of the inserts, less efficient cutting,
and consequent loss of blade life. Use "Gum and
Pitch Remover" or oven cleaner, to wipe off the
inserts.
When blade inserts become dull enough so that it
is noticeable when cutting, they should be rotated
to a fresh edge or replaced entirely. A sharp blade
works easier and results in longer blade life. The
penalty paid for a dull blade is less blade life and
greater wear and tear on all parts of the machine.
