SAFETY RULES
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 limita-
tions 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
groundingplug connectsto asuitable ground. Followthe groundingprocedure indicatedin theNational Electri-
calCode.
Eye safety. Wear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Common eye-
glasses are only impact resistant, they are not safety glasses.)
Personal protection. Beforeoperating themachine, removetie, rings,watch andother jewelryand rollup
sleevesabove theelbows. Remove alllooseouter clothingand confinelonghair.Protectivetypefootwear
should be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA
Regulations,use hearingprotectivedevices. Donotwear gloves.
Guards. Keep the machine guards in place for every operation for which they can be used. If any guards are
removedfor maintenance,DO NOTOPERATE themachine untilthe guardsarereinstalled.
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
normallystands andthat eachmachine’s workarea bemarked off. Provideadequate workspace aroundthe
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
theblade.
Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, and
cleaningrags awayfrom thesaw.
Careless acts. Givethe workyou aredoingyour undividedattention. Lookingaround,carrying ona conversa-
tion, and “horseplay” are careless acts that can result in serious injury.
Disconnect machine beforeperforming anyservice ormaintenance orwhenchanging blades. Amachine
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.Acaution decal is installed
oneach guardand splitterto remindthe operatorof thedangers ofmisalignment.
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
sawblade running. Neversaw freehand. Avoidawkward operationsand handpositionswhereasudden 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,
usefeatherboards (seepage 15),fixtures and othersafety devicesand use extremecaution. Reinstall the
splitterand bladeguard immediatelyaftercompleting theoperation thatrequired theirremoval.
Saw blade rotation. Be sure the saw blade rotates clockwise when viewed from the motor side (left side) of
themachine.
Adjustments. Makeall adjustmentsto themachine andoperational setupwiththe poweroff. Never remove
theinsert withthe bladerunning.
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
jointedfor guidingpurposes priortosawing.
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 theoperator leavesthe machinearea forany reason,he shouldturn “off”thepower tothe
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; other-
wisethe tablesaw warrantyand guaranteeis nulland 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.
If you are not thoroughlyfamiliarwiththe operationofTable Saws,obtainadvice fromyour supervisor,instruc-
toror otherqualifiedperson.
Drugs, alcohol, 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 ex-
amples of these chemicals are:
* Leadfromlead-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
exposuretothese chemicals,work ina well-ventilatedarea,and workwith approvedsafety 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).

ADJUSTMENTS
MITER SLOT ALIGNMENT
To check the alignment of the miter slot to the blade,
raisethe bladeto its0 (90deg.)position andits maxi-
mumheight. Mark onetoothwith agrease penciland
position the tooth slightly above the top edge of the
table at the front. Raise the miter gauge bar slightly
out of its slot to serve as a shoulder. Using a combi-
nation square against the side of the bar, slide the
scaleover untilit touchesthetipofthe bladeand lock
scale in position, Figure 5.
FIGURE5
Rotatethe markedtoothsothatit isslightlyabove the
table top at the rear and using the square as in front,
check whether the distance to the blade is the same.
If it is not, loosen the three (3) mounting screws that
lock the table to the cabinet and move the table to
bring the miter slot in line with the blade. The blade
should be kept centered with the slot in the table in-
sert to ensure clearance at both the 90 deg. and 45
deg. positions. After aligning, lock the table to the
cabinetby retighteningthe threemounting screws.
TILT STOP ADJUSTMENT
Using a combination square, check the 90 deg. (0)
and 45 deg. stops as shown in Figure 6. Adjust stop
positionsif required,usingthestopscrews asshown.

MITRE GAUGE ADJUSTMENT
The mitre gauge is equipped with individually adjust-
able index stops at 90 degrees and 45 degrees right
andleft. Theindex stopscan beadjusted bytighten-
ing or loosening the three adjusting screws (A), Fig-
ure7.
To operate the mitre gauge, loosen lock handle (B),
and move the body of the mitre gauge (C) to the de-
sired angle. The mitre gauge body is set to stop at 0
degrees and 45 degrees left or right. To move the
gaugebeyond thesepoints, thestoprod (D),must be
pulledout.

SCORING BLADE BELT TENSIONING
The scoring blade belt is tensioned by the weight of
the motor. If the belt should lose its tension, check
the scoring motor pivot screws for binding. See Fig-
ure9.
ARBOR AND ARBOR BEARING REMOVAL
To remove the saw arbor, remove the table top. Re-
move the lock nut, pulley and key. Use a wrench on
theendof thearbor tohold it whileloosening thenut.
Loosen the setscrew in the saw raising arm and the
arbor; bearings and spacer will then slide out of the
armhousing, Figure10.

NOTE: The saw arm setscrew must be tight to avoid
the possibility of movement which could cause the
blade to hit the insert.
FIGURE11
SPLITTER ALIGNMENT
Oneofthe mostcriticaladjustmentstohelp avoidkick-
backs is the splitter alignment. It should be checked
andreadjusted ifnecessary aftereachblade change.
To align the splitter to the blade, use a combination
square against the side of the raised up miter gauge
bar and slide the scale against the top of the tooth as
shownin Figure12.
Check the splitter for parallelism to the miter slot and
readjustif required. Checkfor clearance.
Movethemiter gaugetotheopposite sideoftheblade

INSTRUCTIONS & PROCEDURES
FOR CIRCULAR SAW
OPERATIONS
GENERALINSTRUCTIONS
1. Familiarizeyourselfwiththelocation andop-
erationof allcontrols andadjustments andthe useof
accessories such as the miter gauge and rip fence.
2. Seriousinjurycanresultfrom kickbackswhich
occur when a work piece binds on the saw blade or
binds between the saw blade and rip fence or other
fixed object. This binding can cause the work piece
to lift up and be thrown toward the operator. Listed
beloware theconditions whichcan causekickbacks:
a.Confining thecutoff piecewhen cross
cuttingor ripping.
b.Releasing theworkpiecebefore complet-
ing the operation or not pushing the work piece
all the way past the saw blade.
c. Not using the splitter when ripping or not
maintainingalignmentof thesplitter withthesaw
blade.
d. Using a dull saw blade.
e.Not maintainingalignmentoftheripfence
sothat ittendsto angletowardratherthanaway
from the saw blade front to back.
NOTE: Caution decal on guard and splitter as-
sembly.
f.Applyingfeedforce whenripping tothecut-
off(free) sectionofthe workpieceinstead ofthe
sectionbetween thesaw bladeand fence. Use
push sticks or push blocks, Figure 17, for nar-
row, thin, or short work.
g. Ripping wood that is twisted (not flat), or
doesnothave astraightedge,ora twistedgrain.
FIGURE17
3. Tominimize orpreventinjury fromkickbacks:
a.Avoidconditions listedabove.
b. Wear a safety face shield, goggles, or
glasses.
c. Do not use the miter gauge and rip fence
inthe sameoperation unlessprovision ismade
by use of a facing board on the fence so as to
allowthecutoff sectionoftheworkpiecetocome
freebeforethenextcutis started(Seepg. 13for
instructiononcross-cutting).
d. Check the operation of the anti-kickback
pawls before starting a cut. If the pawls do not
stopthereversemotionofaworkpiece,resharpen
all the points.
e.Where possible,keep yourface andbody
outoflinewithpotentialkickbacksincludingwhen
starting or stopping the machine.
4. Dull, badly set, improper, or improperly filed
cutting tools and cutting tools with gum or resin ad-
hering to them cause many of the tilting arbor saw
accidents. Neverusea crackedsaw blade. Theuse
of a sharp, well maintained, and correct cutting tool
forthe operationwill helpto avoidinjuries.
5. Support the work properly and hold it firmly
againstthe gaugeor fence. Usea pushstick orpush
blockwhen rippingshort, narrow(6" widthor less),or
thin work. Use a push block or miter gauge hold-
downwhen dadoingormolding.
6. For increased safety in crosscutting, use an
auxiliarywood facingattached tothe mitergauge us-
ingthe holesprovided, Figure18.

12
FIGURE18
7. Never use the fence as a length stop when
crosscutting. Donot holdonto,ortouch, thefreeend
or cutoff section of a workpiece. On thru sawing op-
erations,the cutoffsection mustNOT beconfined.
8. Alwayskeepyourhandsout ofthe lineof the
sawbladeand NEVERreachbackofthecuttingblade
witheitherhand tohold theworkpiece.
9. Bevelrippingcutsshouldalwaysbemadewith
thefence ontheright sideofthe sawbladeso thatthe
theblade tiltsaway fromthe fenceand minimizesthe
possibility of the work binding and the resulting kick-
back.
10. Use themitergaugeontheright-handsideof
the saw blade when doing miter or compound miter
cutsto providemore handclearance andsafety.
RIP SAWING
1. Ripping is a sawing process where the work
pieceis fedwiththe grainintothe sawbladeusing the
fence as a guide and a positioning device to ensure
the desired width of cut, Figure 19.
FIGURE19
CAUTION: Beforestarting aripping cut,be sure
the fence is clamped securely and aligned
properly.
Never rip freehand or use the miter gauge in combi-
nationwith thefence.
Never rip workpieces shorter than the saw blade di-
ameter.
Never reachbehind thebladewith eitherhandto hold
down or remove the cutoff piece with the saw blade
rotating.
2. Alwaysusethe sawguard, splitterand kick-
backpawls. Makesurethesplitteris properlyaligned.
When wood is cut along the grain, the kerf tends to
closeand bindon thebladeand kickbackscan occur.
NOTE: A caution decal is installed on the guard and
splitter assembly warning of the hazard of misalign-
ment (see pg. 8 for alignment instructions).
3. The rip fence should be set for the width of
the cut by using the scale on the front rail or by mea-
suring the distance between the blade and fence.
Standout ofline withthe sawblade andworkpiece to
avoidsawdust andsplinters comingoffthebladeand
a kickback, if one should occur.
4. If the work piece does not have a straight
edge, nail an auxiliary straight edged board on it to
provide one against the fence. To cut properly, the
board must make good contact with the table. If it is
warped,turn thehollow sidedown.
5. In ripping, use one hand to hold the board
down against the fence or fixture, and the other to
pushitintotheblade betweenthebladeandthe fence.
If the workpiece is narrow (less than 6") use a push
stick or push block. Never push in a location such
that the pushing hand is in line with the blade. Move
thehandserving asa holddowna safedistance from
the blade as the cut nears completion. For very nar-
rowripping wherea pushstick cannotbe used,use a
push block or auxiliary fence. Always push the
workpiece completely past the blade at the end of a
cut to minimize the possibility of a kickback.
6. When ripping long boards, use a support at
the front of the table and a support or "tailman" at the
rearasshown inFigure 20.

use a push stick or block to push it through between
thefenceand thesaw blade.
8. Neverusetheripfencebeyondthepointwhere
the carriage is flush with the end of the rails.
9. Have the blade extend about 1/8" above the
top of the workpiece. Exposing the blade above this
pointcan behazardous.
RESAWING
1. Resawingisa rippingoperationinwhich thick
boardsare cutintothinnerones. Narrowboardsupto
3" can be resawed in one pass. Wider boards up to
6" must be resawed in two passes.
2. In resawing wider boards, adjust the blade
heightsoas tooverlap thetwo cutsby 1/2"as shown
inFigure 21. Too deepa firstcut canresult inbinding
and possible kickbacks on the second cut. Always
use the same side of the board against the fence for
both cuts.

CROSSCUTTING
1. The sawing process where the workpiece is
fedcrossgrainintothesawbladeusingthemitergauge
tosupport andposition theworkpiece iscalled cross-
cutting,Figure22. Crosscutting shouldnever bedone
freehandnor shouldthefencebe usedasan endstop
unlessan auxiliaryblock isclampedto thefront ofthe
blade area such that the cutoff piece comes free of
the block before cutting starts. Length stops should
not be used on the free end of the workpiece in the
cutoffarea.
DoNOT crosscutworkpieces shorterthan6". Before
starting a cut, be sure the miter gauge is securely
clamped at the desired angle. Hold the workpiece
firmly against the table and back against the miter
gauge. Always use the saw guard and splitter and
make sure the splitter is properly aligned.
FIGURE22
2. For 90 degree crosscutting, most operators
prefer to use the left-hand miter gauge slot as shown
in Figure 22. 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
usingtherighthandslotformiterandcompound cross-
cuttingso thatthebladetiltsawayfromthe gauge,the

3. When using the miter gauge, the workpiece
mustbe heldfirmly andadvanced smoothlyat aslow
rate. If the workpiece is not held firmly, it can vibrate
causingit tobind onthe bladeand dullthe sawteeth.

5. Provide auxiliary support for any workpiece
extending beyond the table top with a tendency to
sag and lift up off the table.
6. Stop rods can be used in the holes provided
in the miter gauge for repetitive work of equal length.

BEVEL & MITER OPERATIONS
1. Abevelcutisaspecialtypeofoperationwhere
the saw blade is tilted at an angle less than 90 de-
grees to the table top. Operations are performed in
the same manner as ripping or crosscutting except
thefence ormiter gaugeshould beused onthe right-
handside ofthe sawblade toprovideaddedsafetyin
avoidinga bindingaction betweenthe sawblade and
the table top. When beveling with the miter gauge,

2. Crosscuts made at an angle to the edge of
the workpiece are called miters. Set the miter gauge
atthe requiredangle,lockthemiter gauge,andmake
the cut the same as a normal crosscut except the
workpiecemust beheld extrafirmly topreventcreep-
ing.
3. Have the blade extend only 1/8" above the
