As with all machines, there is a certain amount of hazard involved with the use of this table saw. 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, understand and follow the safety and operating instructions found in this manual. Know the limitations
and hazards associated with this table saw.
Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground lead is
included in the incoming electrical service. In cases where a cord and plug are used, make certain that the
grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the National Electrical
Code.
Eye safety. Wear an approved safety shield, goggles, or glasses to protect your eyes. (NOTE: Common eyeglasses are not safety glasses.)
Personal protection. Before operating the machine, remove your tie, rings, watch and other jewelry and roll your
sleeves up past the elbows. Remove all loose outer 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. Keep the machine guards in place for every operation for which they can be used. If any guards are
removed for maintenance, DO NOT OPERATE the machine until the guards are reinstalled.
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.
Operator position. Maintain a balanced stance and keep your body under control at all times. Do not stand in
line with the saw blade or work piece and do not allow anyone else to do so. Never climb on or near the saw.
Do not overreach. Use a support table or have a helper or “tailman” take stock away from the back side of the
blade.
Housekeeping. Before turning on the machine, remove all extra equipment such as keys, wrenches, scrap, and
cleaning rags away from the saw.
Careless acts. Give the work you are doing your undivided attention. Looking around, carrying on a conversation,
and “horseplay” are careless acts that can result in serious injury.
Disconnect the machine before performing any service or maintenance or when changing blades. A machine
under repair should be RED TAGGED to show it should not be used until the maintenance is complete.
Alignment. Check the alignment of the splitter, fence and miter slot to the blade. A caution label is installed on
each guard and splitter to remind the operator of the dangers of misalignment.
Maintain tools in top condition. Check the saw blade for cracks or missing teeth. Do not use a cracked or dull
blade or one with missing teeth or improper set. Make sure the blade is securely locked on the arbor.
Hand safety. Keep hands clear of the blade area. Do not reach past the blade to clear parts or scrap with the saw
blade running. Never saw free hand. Avoid awkward operations and hand positions where a sudden slip could
cause your hand to contact the blade.
Safety devices. Always use the splitter, blade guard, push stick and other safety devices for all operations where
they can be used. On operations such as dadoing or molding where the blade guard cannot be used, use feather
boards, fixtures and other safety devices and use extreme caution. Reinstall the splitter and blade guard immedi-
4
Page 5
ately after completing the operation that required their removal.
Saw blade rotation. Be sure the saw blade rotates clockwise when viewed from the motor side (left side) of the
machine.
Adjustments. Make all adjustments to the machine and operational setup with the power off. Never remove the
insert with the blade running.
Material condition. Do not attempt to saw boards with loose knots or with nails or other foreign material, on its
surface. Do not attempt to saw twisted, warped, bowed or “in wind” stock unless one edge has been jointed for
guiding purposes prior to sawing.
Large stock. Do not attempt to saw long or wide boards unsupported where spring or weight could cause the
board to shift position.
Job completion. If the operator leaves the machine area for any reason, he should turn “off” the power to the table
saw motor and wait until the saw blade comes to a complete stop before his departure. In addition, if the operation
is complete, he should clean the table saw and the work area. NEVER clean off the table saw with power “on” and
NEVER use the hands to clear sawdust and debris; use a brush.
Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories; otherwise
the table saw warranty and guarantee is null and void.
Misuse. Do not use this Powermatic table saw 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 this table saw with a motor larger than five (5) horsepower at 3600 RPM. Doing
so voids the warranty and Powermatic holds itself harmless from any injury which may result.
Operation. If you are not thoroughly familiar with the operation of Table Saws, obtain advice from your supervisor,
instructor or other qualified person.
Drugs, alcohol and medication. Do not operate this machine 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 dust
masks that are specifically designed to filter out microscopic particles.
Use proper extension cord. Make sure your extension cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause
a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.

3.Carefully set the machine in the upright position.
4.With the saw located at the place of operation,
(with a solid foundation), spread the stand legs to selfalign the machine. (If your going to use an optional
mobile base, place the machine onto the base now).
When all four legs are seated solidly on the floor (or
base), securely tighten all of the nuts and screws in
the stand assembly.
NOTE: If the saw is to be used without the metal
stand provided, care must be taken to provide a hole
in the stand or bench utilized by the operator to facilitate the removal of sawdust.
CAUTION: If the saw has any tendency to
slide, walk, or tip over during operation,
!
the stand or bench MUST be secured to the
floor.

GROUNDING INSTRUCTIONS
1.All grounded, cord connected tools:
•In the event of a malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This
saw is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is
properly installed and grounded in accordance with all
state and local codes and ordinances.
•Do not modify the plug provided - if it will not fit
the outlet, have the proper outlet installed by a qualified electrician.
•Improper connection of the equipment-grounding
conductor can result in the risk of electric shock. The
conductor with insulation that is green with or without
yellow stripes is the equipment-grounding conductor.
•If repair or replacement of the electric cord or
plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.
•Check with a qualified electrician or service per-
sonnel if the grounding instructions are not completely
understood, or if in doubt as to whether the saw is
properly grounded.
•Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the saws plug.
•Repair or replace a damaged or worn cord imme-
diately.
FIGURE 22

Page 17
2.Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating less than
150 volts:
•This saw is intended for use on a circuit that has
an outlet that looks like the one shown in Figure 23(A).
•A temporary adapter, which looks like the adapter
shown in Figure 23(B&C), may be used to connect
this plug to a 2-pole receptacle as shown in view (B) if
a properly grounded outlet is not available. The temporary adapter should only be used until a properly
grounded outlet can be installed by a qualified electrician.* The green-colored rigid tab or lug, extending
from the adapter, must be connected to a permanent
ground such as a properly grounded outlet box.
*This adaptor is not applicable in Canada.
3.Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating between150-250 volts, inclusive:
•This cord is intended for use on a circuit that has
an outlet that looks like the one shown in Figure 23(D).
Make sure the saw is connected to an outlet having
the same configuration as the plug. No adapter is available or should be used. If the saw must be rewired for
use on a different type of electric circuit, the rewiring
should be made by a qualified service personnel, and
after rewiring the saw should comply with all state and
local electrical codes and ordinances. See page 26
for 230V wiring diagram.

the following:
1.Set the saw blade to cut at 90o.
2.Remove the front lock knob and raise the
handwheel (A & B, Figure 24) to make the pointers
set screw accessible as shown in Figure 25.
3.Loosen the set screw and move the indicator point
to "0" on the scale.
4.Lock the set screw and reinstall the handwheel
and lock knob.

3.Set the blade at 90
to the table by turning the
blade tilting handwheel clockwise as far as it will go.
4.Place a square on the table and check to see
that the blade is at a 90
o
angle as shown in Figure 26.
5.If the blade is not at 90o, proceed as follows: The
90o stop is located on the trunnion bracket toward the
front of the saw as shown in Figure 27. Loosen the
lock nut (A) and turn the adjusting stop screw (B) with
a wrench until the screw contacts the underside of the
table at the blade's 90o position. Tighten the lock nut.
Re-check and adjust as necessary.
6.The stop screw for 45o is located toward the front
of the saw on the cylindrical trunnion link bar as shown
in Figure 27. If the saw is not cutting at 45o, loosen the
lock nut (C) with a 14mm wrench. Adjust it to the proper
position by holding the stop screw (D) with one wrench
while tightening the lock nut (C) with the other.
MITRE GAUGE ADJUSTMENT
Tools Required
8mm wrench
phillips screwdriver
Your mitre gauge is equipped with individually adjustable index stops at 90o and 45o right and left. The index stops can be adjusted by tightening or loosening
the three adjusting screws (A) as shown in Figure 28.
•To operate the mitre gauge, loosen the lock
handle (B) and move the body of the miter gauge (C)
to the desired angle. The mitre gauge body is set to
stop at 90o and 45o left or right. To move the gauge
beyond these points, the stop link (D) must be flipped
out of the way.
FIGURE 26
FIGURE 27
TO CHECK AND ADJUST THE 90o SETTING OF THE
MITRE GAUGE, DO THE FOLLOWING:
1.Set the gauge at 90o as shown in Figure 28.
!
2.Place a metal square against the face of the mitre gauge and along one edge of the mitre gauge slot
and check to see if the edge of the square fits flush
with the mitre gauge as shown in Figure 29.
3.If it does not, loosen lock handle (B - Figure 28).
4.Loosen the locknut (E), and adjust the stop screw,
(A), so it strikes the stop link (D) when the gauge is at
90o.
5.Tighten both the locknut (E) and the lock handle
(B).

ALIGNING THE SPLITTER TO THE SAW
BLADE
CAUTION: The splitter assembly must be
!
aligned with the saw blade to help
prevent kickback.
1.Lay a straight edge against the saw blade and
the splitter as shown in Figure 30.
2.If the splitter and the saw blade do not line up,
loosen the lower screws on the splitter mounting
bracket (D) and the lower screws on the inside splitter
mounting plate (E) as shown in Figure 31.
NOTE: This adjustment is more easily performed with
the aid of a helper since the mounting plate screws
are adjusted from the underside of the saw. A socket
wrench with an extension may be necessary to loosen
the two screws.
3.When the adjustment is finished, tighten all of
the screws.
CAUTION: Make sure the blade guard and
!
the splitter are parallel with the table
mitre slots to prevent binding.
ALIGNING THE SAW BLADE TO THE
TABLE SLOT
1.If the blade is not aligned with the slot in the
table, loosen the screws on the trunnion brackets
(Items 17 and 54 on page 35) and bump the table as
needed with a mallet.
2.Tighten the screws securely when finished.
FIGURE 29
FIGURE 30
MAINTENANCE
Good saw operation requires periodic preventive maintenance.
1.Keep the inside of the cabinet and trunnion areas clean. A stiff brush will remove sawdust before it
cakes, and pitch or sap is easily removed with a commercial solvent.
2.After cleaning the tilting and raising worm, worm
gear segments, and the trunnions, grease these three
areas with a good grade non-hardening grease.
3.The table surface must be kept clean and free of
rust for best results. An occasional coat of paste wax
on the table will allow the wood stock to glide smoothly
across the work surface.
20
FIGURE 31
Page 21
Note: An alternative to the paste wax is white talcum
powder applied with a blackboard eraser rubbed in vigorously once a week to fill casting pores and form a
moisture barrier. This method provides a table top that
is slick and allows rust rings to be easily wiped from
the surface. It is also important to note that talcum
powder will not stain wood or mar finishes as wax buildup does.
BASIC SAW OPERATION
1.Familiarize yourself with the location and operation of all the controls and adjustments of the saw,
and the use of the mitre gauge and rip fence.
2.Serious injury can result from kickbacks. Kickbacks occur when a workpiece binds on the saw blade
or binds between the saw blade and rip fence or other
fixed object. This binding can cause the workpiece to
lift up and be thrown toward the operator (kickback).
Listed below are the conditions that can cause kickbacks and should be thoroughly familiar to the operator.
a.Confining the cutoff piece when crosscutting
or ripping.
b.Releasing the workpiece before completing
the operation or not pushing the workpiece
all the way past the saw blade.
c.Not using the splitter when ripping or not
maintaining alignment of the splitter with the
saw blade.
d.Using a dull saw blade.
e.Not maintaining alignment of the rip fence. (Fence
should angle away from, rather than towards, the
saw blade front to back).
NOTE: A caution label on the guard and splitter assembly warns against misalignment.
f.Applying feed force, in ripping, to the cutoff (free)
section of the workpiece instead of the section between the saw blade and fence. Use push sticks or
push blocks for narrow, thin, or short work.
g.Ripping wood that is twisted (not flat), does not
have a straight edge, or has a twisted grain.
To minimize or prevent injury from kickbacks:
a.Avoid the conditions listed above.
b.Wear a safety face shield, goggles, or glasses.
21
Page 22
c.Do not use the mitre gauge and rip fence in the
same operation unless provision is made of a facing
board on the fence to allow the cutoff section of the
workpiece to come free before the cut is started. (See
page 24).
d.Check the operation of the anti-kickback pawls
before starting a cut. If the pawls do not stop the reverse motion of a workpiece, resharpen all the points.
e.Keep your face and body out of line with potential kickbacks when possible, including when starting
or stopping the machine.
3.Dull or improperly sharpened blades and blades
with gum or resin adhering to them may cause an
accident with the tilting arbor saw. Never use a cracked
saw blade. The use of a sharp, well maintained, and
correct cutting blade for the operation will help avoid
kickbacks.
4.Support the work properly and hold it firmly
against the gauge or fence. Use a push stick or block
when ripping short, narrow (6" width or less), or thin
work. Use a push stick or mitre gauge hold-down when
dadoing or molding as shown in Figure 32.
5.For added safety in crosscutting use an auxiliary wood facing board attached to the mitre gauge
using the holes provided as shown in Figure 33.
6.Never use the fence as a length stop when crosscutting. Do not hold on to or touch the free end or
cutoff section of a workpiece. Throughout the sawing
operations, the cutoff section must not be confined.
7.Always keep your hands out of line with the saw
blade and never reach past the rotating blade with either hand to hold down the workpiece.
8.Use the mitre gauge on the left hand side of the
saw blade when doing mitre or compound miter cuts
to provide more hand clearance and safety.
OPERATING PROCEDURES
RIPPING
1.Ripping is a sawing process where the workpiece
is fed with the grain aligned with the saw blade using
the fence both as a guide and a positioning device to
ensure the desired width of cut as shown in Figure 34.
Many manufacturers make blades specifically designed
for this operation.
FIGURE 32
FIGURE 33
CAUTION: Before starting a ripping cut, be
sure the fence is clamped securely and
!
properly aligned.
22
Page 23
Never rip freehand or use the mitre gauge in combination with the fence. Never rip workpieces shorter
than the saw blade diameter without a push stick.
Never remove the cutoff piece with the saw blade rotating.
2.Always use the saw guard, splitter and anti-kickback pawls and make sure the splitter is properly
aligned. When wood is cut along the grain, the kerf
tends to close and bind the saw blade and kickbacks
can occur.
NOTE: A caution label is installed on the guard and
splitter assembly warning of the hazard of misalignment.
3.The rip fence should be set for the width of the
cut by using the scale on the front rail or measuring
the distance between the blade and fence as shown
in Figure 35.
4.Stand out of line with the saw blade and
workpiece to avoid sawdust and splinters coming off
the blade and a possible kickback.
5.If the workpiece does not have a straight edge,
nail an auxiliary straight edged board to it to provide a
straight edge against the fence. To cut properly, the
board must make good contact with the table. If it is
warped, turn the hollow side down.
FIGURE 34
6.In ripping, use one hand to hold the board down
and against the fence or fixture and put the other between the saw blade and the fence to push it into the
saw blade. If the workpiece is narrow (less than 6")
use a push stick or push block. Never push in a way
that the pushing hand is in line with the saw blade.
Move the hand serving as a hold-down a safe distance
from the saw blade as the cut nears completion. For
very narrow ripping where a push stick cannot be used,
use a push block or an auxiliary fence.
7.Always push the workpiece completely past the
saw blade at the end of a cut to minimize the possibility of a kickback.
8.When ripping long boards, use a support at the
front of the table and a support or “tailman” at the rear.
9.For work shorter than 12" or narrower than 6",
use a push stick, or block, between the fence and the
saw blade to push it through. (See page 27 for a filler
piece designed to add to the safety of ripping narrow
boards).
10. NEVER use the rip fence beyond the point where
the carriage is flush with the end of the rails.
FIGURE 35
11. Adjust the saw blade height so it extends about
1/8" above the top of the workpiece. Raising the saw
blade above this point increases the risk of injury.
23
Page 24
RESAWING
1.Resawing is a ripping operation in which thick
boards are cut into thinner ones. Narrow boards up to
3" can be resawed in one pass. Wider boards up to 6"
must be resawed in two passes.
2.When resawing wider boards, adjust the saw
blade height so it overlaps the two cuts by 1/2" as
shown in Figure 36. Too deep of a first cut can result
in binding and kickbacks on the second cut. Always
place the same side of the board against the fence for
both cuts.
CROSSCUTTING
1.Crosscutting is a sawing process where the
workpiece is fed with the grain perpendicular to the
saw blade using the mitre gauge to support and position the workpiece.
CAUTION:Do not crosscut workpieces
!
shorter than 6".
FIGURE 36
2.Before starting a cut, make sure that the mitre
gauge is securely clamped at the desired angle. Hold
the workpiece firmly against the table and back against
the mitre gauge as shown in Figure 37. Always use
the saw guard and splitter and make sure the splitter
is properly aligned.
3.Crosscutting should never be done freehand nor
should the fence be used as an end stop unless an
auxiliary block is clamped to the front of the blade
area such that the cutoff piece comes free of the block
before cutting starts as shown in Figure 38. Length
stops should not be used on the free end of the
workpiece in the cutoff area.
4.For 90o crosscutting, most operators prefer to
use the left-hand mitre gauge slot. When using it in
this position, hold the workpiece against the gauge
with the left hand and use the right hand to advance
the workpiece. When crosscutting using the right hand
slot, reverse the hand positions.
5.When using the mitre gauge, the workpiece must
be held firmly and advanced smoothly at a slow rate.
If the workpiece is not held firmly, it can vibrate causing it to bind on the saw blade and dull the teeth.
FIGURE 37
FIGURE 38
6.To improve the effectiveness of the mitre gauge
in crosscutting, some users mount an auxiliary wooden
extension face with a glued-on strip of sandpaper to
the gauge as shown in Figure 39.
7.Provide auxiliary support for any workpiece which
tends to sag and lift up off the table when it extends
beyond the table top.
24
Page 25
8.Adjust the saw blade height so it extends about
1/8" above the top of the workpiece. Raising the saw
blade above this point increases the risk of injury.
BEVEL AND MITRE OPERATIONS
1.A bevel cut is a special type of operation where
the saw blade is tilted at an angle less than 90o to the
table top. Beveling is done in the same manner as
ripping or crosscutting. When beveling with the mitre
gauge, the workpiece must be held firmly to prevent
creeping as shown in Figure 40.
2.Crosscuts made at an angle to the edge of the
workpiece are called mitres. Set the mitre gauge to
the required angle and lock it. Make the cut the same
as a normal crosscut except hold the workpiece tightly
to prevent creeping as shown in Figure 41.
3.Adjust the saw blade height so it extends about
1/8" above the top of the workpiece. Raising the saw
blade above this point increases the risk of injury.
DADO CUTTING
The process of cutting 1/8" to 13/16" grooves in
workpieces is accomplished by the use of a stacked
dado blade set or an adjustable type blade mounted
on the saw arbor.
1.By using various combinations of the stacked
dado blades, or properly setting the dial on an adjustable blade, an accurate width dado can be made. This
is very useful for shelving, making joints, tenoning, etc.
The guard, splitter and anti-kickback pawls supplied
with the saw should be used for all cutting operations
where they can be used. When completing operations
where the supplied guard cannot be used as in some
dadoing operations, alternative safety precautions
should be taken. These include: push sticks, feather
boards, filler pieces, fixtures, jigs and any other appropriate device that can be utilized to keep operators’ hands away from the blade. See page 27.
FIGURE 39
FIGURE 40
2.Upon completion of the operation requiring removal of the guard, the entire guard assembly must
be placed back on the machine in its proper working
position.
CAUTION:Never use a wedge between
!
the arbor collar and saw blade to create a
"wobble" dado. Never operate the saw
without the guard, splitter and anti-kickback
pawls for operations where they can be
used. Never use a dado head in a tilted
position.

SAFETY DEVICES
Filler Piece (Figure 45)
Feather Board (Figure 44)
A Feather Board is made of straight grain hardwood
approximately 1” thick and 4" to 8" wide. The length is
developed in accordance with intended use. Feather
Boards can be fastened to the table or rip fence by
use of “C” clamps. Drilled and tapped holes in the table
top allow the use of wing nuts and washers as a method
of clamping. Provide slots in the feather board for adjustment if this method of fastening is used. (See illustration for method of attaching and use of the feather
board as a vertical comb. The horizontal application is
essentially the same except that the attachment is to
the table top).
A filler piece is necessary for narrow ripping and permits the guard to remain on the machine. It also provides space for the safe use of a push stick.
