Safety Rules
As with all machines, there is a certain amount of hazard involved with the use of this jointer. Use the machine
with the respect and caution demanded where safety precautions are concerned. When normal safety precautions are overlooked or ignored, personal injury to the operator can result.
Read the manual. Read, understand, and follow the safety instructions found in this manual. Know the limitations and hazards in using the model 60 - 8" 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.
There are no exceptions to this rule.
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
T AGGED 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.
Never surface stock less than 12 inches long, or
3 inches wide, or 3 inches thick without a hold-down
push block.
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 i.
4
FIGURE i
Page 5
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.
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 ii).
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 2 Horsepower at 3600 R.P.M. or operate
the cutterhead in excess of 7,000 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.
FIGURE ii
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.
Familiarize yourself with the following safety notices used in this manual:
!
CAUTION: (This means that if precautions are not heeded, it may result in minor or moderate injury
and/or possible machine damage)
WARNING: (This means that if precautions are not heeded, it could result in serious injury or
!
possibly even death).

wired to run, the electrical and motor
wiring must be done by a qualified
electrician. The machine must be properly
grounded to help avoid electrical shock
and possible death.
MOUNTING DRIVE BELT
1.Place the belt over the cutterhead pulley and
through the hole in the stand.
2.With a 9/16" wrench, loosen the nut on the adjusting screw (A) of the motor support plate (B) and
lift the motor support up until the belt can be rolled
onto the motor pulley . See Figure 3.
3.Push down on the motor support and retighten
the nut on the adjusting screw (A) to create tension
on the belt.
4.Using thumb and index finger, compress belt at
center until it becomes taut. See Figure 4. At this
point the distance between the in-sides of the belt
should be one inch. Raise or lower the adjusting
screw on the motor support as necessary until this
proper tension is achieved.
ALIGNING PULLEYS
Check that the motor and cutterhead pulleys are
aligned. If adjustments are necessary, loosen the
screws (C) in the motor support plate, as shown in
Figure 3, and slide the motor back or forward as needed.
Re-tighten screws when finished.

ADJUSTMENTS
Check all mounting screws and set screws to see
that they are locked.
CAUTION: Disconnect machine from
!
power source before making adjustments.
REMOVING CUTTERHEAD GUARD
Some adjustment procedures, as well as rabbeting
operations, will require removal of the guard.
1.Loosen lock nut (A) on rabbeting ledge with a
1/2" wrench. Loosen set screw (B) with a 5/32" hex
wrench. See Figure 7.
2.Vertically lift guard assembly out of the hole.
3.To re-install the guard properly, tension must
be placed on the spring. Push the guard shaft down
into the hole on the rabbeting ledge, and turn the top
knob (C) clockwise until the desired tension is
reached.
4.Continue holding the knob, and tighten the set
screw (B). Tighten the lock nut (A) to prevent set
screw from backing out.
5.With the fence moved back toward the rear
edge of the table, test the guard tension by swinging
the guard away from the fence and then releasing it.
If tension is too strong or too weak, re-adjust as necessary.
NOTE: The guard must operate freely and must not
drag on the rabbeting ledge or infeed table. If dragging occurs, replace the guard assembly .
FIGURE 7
LEVELING TABLES
Periodically check the parallelism of the infeed and
outfeed tables by placing a steel straight edge (or carefully jointed wood) across both tables. Non-parallelism caused by loose gibs may be corrected by the
following procedure:
1.Loosen lock nuts on the gib screws (A), then
loosen the gib screws, and the table lock handle (B).
See Figure 8.
2.Remove lower gib screw (A*) and check screw
hole to make sure that punch mark in the gib is aligned
with the screw hole. If punch mark is not visible, or it
does not line up with screw hole, use a screwdriver to
lightly tap the gib back up into alignment.
3.Replace the lower gib screw (A*) but do not
tighten.
10
FIGURE 8
Page 11
4.Carefully tighten the table lock screw (B) as
shown in Figure 8. The table will begin to move toward the straightedge.
5.When aligned, reset the gib screws (A) until
tight. If table does not align with straightedge, use
the adjusting arm (C) for the infeed table, or
handwheel (D) for the outfeed table, until the table is
flush with the straightedge.
6.Tighten the gib screws (A) then back off approximately 1/4 turn or until the table moves freely,
and reset lock nuts on the gib screws.
If table will not line up:
Remove gib screws and table locking handle and remove gib. Check gib to see that set screws do not go
all the way through the gib or dimple the opposite
side. If either of these conditions exist, replace with
a new gib.
Also, check to be sure the ways are clean and free of
pitch and sawdust. Lubricate gib and way with a good
grade of non-hardening grease.
Replace the gib making certain that the punch mark
lines up with locking screw holes. Replace gib screws.
Repeat steps 3 thru 6.
ADJUSTING DEPTH OF CUT
Depth of cut is determined by the height of the infeed
table relative to the cutterhead.
To adjust infeed table:
1.Loosen the lock screw (A), and the locking
handle (B). See Figure 9.
2.Raise or lower the height adjustment handle (C)
until the scale (D) reads approximately at the correct
depth of cut.
3.Turn the locking handle (B) until it is snug, then
fine-tune the adjustment with the height adjustment
handle (C) by rotating it until the scale reads exact.
(Clockwise raises the table, counterclockwise lowers
the table.) The fine adjustment handle has 1/16" travel
per rotation.
4.When set, retighten lock screw (A).
Periodically check the accuracy of the depth of cut
scale (D) by raising the infeed table until it is flush
with the peak of the cutterhead arc (using a straight
edge across table and cutterhead). The scale should
read zero depth. If it does not, readjust the pointer.
FIGURE 9
11
Page 12
SPRING CUTTING
To spring cut, the outfeed table is lowered below the
level of the cutterhead, as in Figure 10. Loosen both
gib screws (A) on the outfeed table. Amount of enddrop is controlled with the table lock screw (B).
Tighten handle to reduce amount of drop. A 1/32"
drop usually creates the ideal concave for spring joints.
Return the outfeed table to be in line with the
cutterhead knives on completion of the cut.
SQUARING THE FENCE
Before operating the jointer, it is important to check
that the fence is perpendicular to the table.
1.Loosen the lock screw (A), as shown in Figure
1 1, and adjust the fence to the 90 degree position.
(NOTE: There will be some play in the fence when it
is unlocked. All play must be removed by tilting the
fence toward or away from the table while locking the
lock screw. Always remove the backlash by tilting
the fence in the same direction while tightening.)
FIGURE 10
2.Place a 90 degree square on the outfeed table
near the cutterhead, and up against the fence. If the
fence does not come to 90 degrees, make the following correction.
3.Loosen lock nut (B) and insert a tool (such as a
hex head wrench) into the hole in the tilt rod (C).
4.Turn tilt rod clockwise or counterclockwise until
the fence lies flush against the square. Tighten lock
nut (B).
5.Check your adjustment by loosening lock screw
(A) and pulling up plunger (D), allowing fence to tilt
out of 90 degrees. Then return it to 90 degree position.
6.Should the fence fail to return to 90 degrees
and play is evident in the fence, remove the plunger
mechanism (D) by loosening the jam nut (E) with a
5/8" wrench. Inspect the conical portion of the plunger
assembly . If the tilt rod shows signs of wear or scarring, grind the conical portion of plunger, Figure 12,
until it will fully engage in the annular groove in the tilt
rod. Replace plunger assembly and tighten jam nut.
FIGURE 11
FIGURE 12
FENCE MOVEMENT & TILTING
The fence may be moved forward and back across
the table by loosening the lock screw (A) as shown in
Figure 13.
12
FIGURE 13
Page 13
NOTE: Lift up slightly on the fence while moving it to
prevent scratching the jointer table.
The fence may also be tilted forward or backward:
1.To tilt the fence forward in the cradle-cut position, loosen the fence lock screw (B). Pull up on the
fence lock plunger (C) and tilt the fence forward.
2.Check the setting with a machinists protractor
or adjustable square.
3.The two jam nuts (D & E) on the end of the tilt
rod are factory pre-set to stop the forward tilt at 45
degrees. See Figure 14. The front nut (D) is used
for adjusting and the rear nut (E) to lock the setting.
When all adjustments have been made retighten the
fence lock screw (B), Figure 13.
4.T o tilt the fence backward, loosen the fence lock
screw (B). Raise or lower the tilt stop screw (F). When
the desired degree of cut is reached, retighten the
fence lock screw (B).
FIGURE 14
INSTALLING NEW KNIVES
When installing new knives remove only one knife at
a time. Clean the knife slot and install the new knife.
Adjust and lock new knife in cutterhead assembly
before proceeding to next knife.
1.Disconnect jointer from power source.
2.Remove the old knives by loosening gib locking bolts and removing gib, knife, and jack screws,
Figure 15.
3.With a hex head wrench, turn jack screws down
one turn. Clean the jack screws, gib, knife slot, and
knife thoroughly and replace jack screws.
4.Sandwich knife and gib together and drop into
knife slot. Be certain that the back of the knife is
resting on the seat of the jack screw plug.
5.To position the knife for rabbeting cuts, a 1/32
inch shop scale should be placed flat on the end of
the cutterhead or the rabbet slot, whichever extends
the farthest. Slide the knife out until it is flush with the
end of the shop scale. Set the knife locking gib 1/32
inch in from the end of the knife. See Figure 16.
FIGURE 15
FIGURE 16
13
Page 14
Setting the proper knife height:
WARNING: Set the knives no more than
!
.015 inches above the body of the cutter head to minimize the hazard of kickback
and severe personal injury .
6.Snug the two outside gib locking screws.
7.If you have a Quick-Set Knife Gauge (available
from POWERMATIC), place it on the outfeed table
and "0" the indicator as shown in Figure 17.
8.Lift the knife gauge off the outfeed table to see
how far below the bottom of the gauge the indicator
travels. The indicator should read between .025 and
.050 as shown in Figure 18.
9.If the indicator reads outside of this range,
loosen the setscrew in the side of the gauge and adjust the indicator so that it will read within the range
above. Zero the indicator as shown in Figure 17. Repeat this process until indicator reads within the .025
to .050 range. Always zero the indicator (as shown in
Figure 17) before each use.
10.Now place it on the outfeed table to the rear of
the cutterhead with the flat indicator point over the
cutterhead. See Figure 19.
FIGURE 17
FIGURE 18
11.Insert a hex head wrench into the jack screw
and rock the cutterhead back and forth. Watch the
pointer on the knife gauge. The pointer will begin
moving toward "0". When the pointer reaches "0", it
is parallel with the outfeed table.
12.Move the gauge to the front of the cutterhead
and repeat the above procedure.
This adjusting process puts the knife into the knife
slot with the tip parallel and flush with the outfeed
table. Once the correct knife height has been established, secure the gib locking screws. (Begin with
the center screw to prevent buckling or uneven
knives.)
SHARPENING THE KNIVES
After extended use it will be necessary to sharpen
the knives on the cutterhead assembly .
CAUTION: Wear approved eye protection
!
when sharpening knives.
FIGURE 19
1.Disconnect machine from power source and
remove the cutterhead guard (see page 10).
14
Page 15
2.Place a shop scale across the infeed and outfeed
tables, as shown in Figure 20.
3.Set tables to the exact height of the high knife
at the high point of its arc.
4.Clamp a block of wood across the infeed table
so that the end of a sharpening stone may be placed
against the wood block during the jointing operation.
This will help to prevent kickback of the stone. See
Figure 21. Lower the outfeed table .003 inches.
5.Re-connect power and turn machine on.
CAUTION:Keep hands clear of turning
!
cutterhead.
6.Place a hard 10" Arkansas oilstone over
cutterhead with ends resting on infeed and outfeed
tables. Slide the oil stone back and forth across the
tables until knives are jointed lightly. Turn the machine off and visually inspect each knife. If only the
high knife has been touched, lower the outfeed table
and continue the sharpening process until every knife
has been touched by the stone.
FIGURE 20
7.After sharpening knives, place a shop scale on
the outfeed table. Raise the outfeed table to the original setting parallel with the knife at the high point of
the arc.
Weekly sharpening will keep knives in the proper
cutting condition. If knives are excessively worn or
nicked, they must be reground to a new bevel. If this
is the case, follow the above procedure.
CUTTERHEAD REMOV AL
To remove the cutterhead, proceed as follows: (see
Figure 22)
1.Disconnect jointer from power source.
2.Remove fence assembly and drive belt.
3.Remove the nuts and washers from the two

BASIC JOINTER OPERATION
Before making actual cuts on the stock, make some
practice runs with the power disconnected and the
infeed table raised to "0". This will acquaint the operator with the feel of jointer operations.
This section briefly discusses some of the basic cuts
using a jointer: surfacing, edging, beveling, skewing,
and rabbeting.
SURF ACING (Planing)
The use of push blocks or handle pads will help to
ensure against the operator's hands coming into contact with the cutterhead in the event of a kickback and
as the trailing end of the board passes over the
cutterhead.
Adjust the infeed table for depth of cut. Cuts of approximately 1/16 inch 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.
Never surface pieces shorter than 12" or thinner than
3/8" without the use of a special work holding fixture.
Never surface pieces thinner than 3" without the use
of a push block. On stock 8" to 12" long, use a single
two-handed push block, as in Figure 24.
With narrow stock use the type push block shown in
Figure 25.
When surfacing short stock over 4" wide, use two push
blocks to guide material over cutterhead. See Figure
26.
FIGURE 24
FIGURE 25
On stock longer than 12" use two push blocks. Place
a push block near the front of piece and start feeding
wood with the right hand until guard has opened and
cut is started. With the push block, direct pressure
down against the table and back against the fence.
See Figure 27. Place second push block near the
rear of infeed table and continue feeding stock. Before the left hand is in the 3" area of the cutterhead,
move it over to the outfeed side. As soon as possible
follow with the right hand over to the outfeed side and
continue through with the cut.
NOTE: When the stock is longer than twice the length
of the infeed and outfeed tables, an assistant or support table must be used to support the stock.
FIGURE 26
FIGURE 27
17
Page 18
EDGING (Jointing)
Never edge a board that is less than 3" wide, less
than 1/4" thick, or 12" long without using a push block.
CAUTION: When workpiece is twice the
!
length of the jointer infeed or outfeed
table, use an infeed or outfeed support.
Begin by feeding stock with the right hand and applying pressure to front of stock with push block. When
edging, make cuts of approximately 1/16" for hardwood and 1/8" for softwood.
When edging stock wider than 3", lap the fingers over
the top of the wood, extending them back over the
fence such that they will act as a stop for the hands in
the event of a kickback. See Figure 28. Keep stock
against the fence.
BEVELING
When beveling never make a cut deeper than 1/16".
Make certain the material being beveled is over 12"
long, more than 1/4" thick and 1" wide. Set fence to
desired angle.
FIGURE 28
CAUTION: Although the fence may be
!
tilted in or out for a bevel cut, Powermatic
recommends for safety reasons that the
fence be tilted in toward the operator,
making a cradled cut.
For stock wider than 3", hold with the fingers close
together near the top of the stock, lapping over the
board and extending over the fence. See Figure 29.
When beveling material less than 3" wide, use beveled push blocks and apply pressure toward the fence,
as shown in Figure 30. Keep fingers near the top of
the push block.
When beveling short material, use one beveled holddown and apply pressure toward the fence. Keep
thumb above the ledge on the hold-down block. See
Figure 31.
When beveling around four edges of a workpiece, make
cross grain cuts first. This will help clean up any chipping or splintering when beveling the end grain.
When beveling long boards, follow the same procedure used for surfacing long boards (page 17).

SKEWING (Shear cutting)
When edging or facing burl or birds-eye maple, it is
not unusual to deface or mar the surface being finished. This is caused by the cutterhead blades at
times cutting against the grain. In order to prevent the
defacing or marring of this type wood, it is necessary
to skew , or angle finish, the material being worked.
1.Release the fence locking handle and remove
the two hex nuts and flat washers holding the fence to
the fence support. Remove the fence assembly .
2.Remove the key from the fence slide base.
3.Replace the fence assembly at the desired angle
across the cutterhead. See Figure 32. Secure the
fence to the support with the lock nut, then tighten the
fence locking handle.
RABBETING
WARNING: A rabbet cut requires removal
!
of the cutterhead guard. Use extreme
caution and keep hands clear of the
cutterhead. Always replace guard
immediately after rabbeting operation is
completed.
The width and thickness of the wood to be rabbeted
depends on the width and length of the rabbet. However, never rabbet a piece of wood less than 12" long.
Use push blocks to rabbet cut whenever possible.
1.Disconnect machine from power source.
FIGURE 32
2.Set fence for the desired width of the rabbet.
3.Check the width of the rabbet by measuring the
distance from the end of a knife in the cutterhead to
the fence.
4.Lower infeed table 1/32" at a time and make
successive cuts until the desired depth of rabbet has
been obtained. See Figure 33. NOTE: It is easier
and safer to take a series of shallow cuts.
When rabbeting long pieces, follow the same procedure for surfacing long pieces (page 17).

PUSH BLOCKS
Push blocks are simple, yet necessary tools to assist the operator, especially when jointing thin or short
stock. Two push pads are included with the
Powermatic 60A Jointer .
Figure 34 shows three commonly-used types of push
block that can be easily made from scrap materials.
