OPERATION SAFETY RULES
WARNING: Operation ofany powertool can result in
foreignobjects being thrown intoeyes which can result
in severe eye damage. Alwayswear safety goggles
complyingwith United States ANSi Z87.1 (shown on
package) before commencing power tool operation.
CAUTION: Always observe the following safety pre-
cautions:
• Knowgeneral powertool safety.Make sure all pre-
cautions are understood (see pages 2, 3 and 5).
• Whenever adjusting or replacing any parts on
planer/molder,turn switch off and remove plug from
power source.
• Make sure all guardsare properlyattached and
securelyfastened.
• Make sure all movingpartsare free from interference.
• Always wear eye protectionor face shield.
• Make sure Imlves are aligned and propedyattached
to ¢utterhead.
• Do not plug in planer/molderunlessswitch is in"off"
position.After turningswitchon, allow planer/molder
to come tofull speed beforeoperating.
• Do not attempt to performan abnormalor little used
operationwithout studyand the use of adequate jigs,
fixtures and the like.
• Keep hands clear of all movingparts.
• Do not force cut. Slowingor stallingwilloverheat
motor.Allow automaticfeed to function properly.
• Use qualitylumber.Bladeslast longerand cutsare
smoother with good qualitywood.
• Do not plane material shorterthan 14½", narrower
than 3A",wider than 12Y="or thinnerthan ½".
• Never make planingcutdeeper than _,_".
• Maintain the properrelationshipsof infeed and out-
feed table surfaces and cutterhead knife path.
• Do not backthe work towardthe infeedtable.
• Take precautions against kickback.DOnot permit
anyone to stand or cross in lineof cuttarhead's rota-
tion. Kickback or throwndebris willtravel in this
direction.
• Turn switchoff and disconnectpower whenever plan-
er/molder is not in use.
• Replace or sharpen knivesas they become dam-
aged or dull.
• Keep planer/molder maintained. Followmaintenance
instructions(see page 12).
DEPTH OF CUT
• Thickness planing refersto the sizingOflumber to a
desired thickness while creating a level surface par-
allelto the oppositeside of the board.
• Qualityof thicknessplaning dependson the opere-
tor'sjudgement aboutthe depthof cut. Depth of cut
depends on the width,hardness,dampness, grain
directionand grainstructureof the wood.
• Maximum thicknessof wood whichcan be removed
in one pass is_" forplaning operations.Foropti-
mum planingperformance,the depthof cutshould
be less than _,4,-.
• Board should be planed with shallowcuts untilthe
work has a level side. Once level surlacehas been
created, flip the lumber and create parallelsides.
Plane alternate sides untilthe desired thicknessis
obtained.
• When half oftotal depthof cut is taken from each
side, the board will have a uniformmoisturecontent
and additional drying will not cause itto warp.
• Depthof cut should beshallowerwhen workiswider.
• When planinghardwood,take lightct_tsor plane the
wood in thin widths.
• Make testcut when workingwith a new type of
board or different kind of operation.
• Check accuracy oftest cut priorto workingon fin-
ished product.

ADJUSTINGTHE DEPTHOF CUT
Refer to Figure 16, page 18.
Board thickness which the planer/molderwillproduce is
indicatedby eitherscale (Key No. 4) on the side.
Thickness is adjusted by rotatingthe handwheel (Key
No.22) clockwise to raise the knifeheight.
To reduce the knife height, rotata the handwheel coun-
terclockwise.
• Do notset knife below %2". Do not plane a board
which isless than a 1,_,thick.
• Knife heightwill be moved 1Ae"with every complete
revolutionof the handwheel.
Make a test cut on a piece of wood and measurethe
thickness produced.
The planer/molder will produce uneven depth of cut
(tapered cut) ifthe cutterhead is not parallel with the table.
To restore parallelism of the cutterhead with the table:
• Clamp a vise plier on the left side of the shaft (Key
No. 6) next to the bevel gear (Key. No. 10).
• Loosen set screws (Key No. 51) and disengage right
bevel gear (Key No. 10) on the elevation screw (Key
No. 18).
• Slowlyrotate handwheel to raise or lower the table.
Rotate clockwise to raise table, counterclockwise to
lower table.Table will be moved by .004" with every
turn of the beveled gear by one tooth.
• After moving table the required distance, make sure
beveled gears (Key Nos. 10 and 12) are engaged
and secured with set screws.
• Release and remove thevise plier
• Make a test cut to make sure the adjustment was
appropriate.
• Add grease to bevel gears if necessary.
When the depth of cut adjustment is operating correctly,
loosen the pan head screw(Key. No.28) and set the
indicator(Key No. 29) to show the thicknessproduced.
Make sure that the indicatoris positionedcorrectly.
TABLE HEIGHT ADJUSTMENT
Refer to Figure 16, page 18.
• The depth of cut ofthe planer/molderis adjusted by
raisingor loweringthe table.
• Rotate the handwheel (Key No.22) to raise or lower
the table to the desired position.
• The scale and indicator(Key Nos. 4 and 29) can be
used when adjusting the table height.
FEED RATE ADJUSTMENT
Refer to Figures 5 and 15, pages 6 and 16.
The planer/molder has a 2-speed gearboxthat feeds
the workplace at 13 feet per minute (FPM) for improved
surfacefinish when moldingor planingand 26 FPM for
fester planing.
• Be suretounplugthe planer/mctderfrom powersource
and turnplaner/molderOFF beforeadjustingthe feed
rate.
Remove the socket head bolt(Figure 15, Key No.
33) that secures the gearboxcover (Figure 15, Key
No.35), remove the gearbox cover.See Figure 5 for
the properlocation of the gears.

26 FPM
Figure 5 - Gear Chart
The planer/molder is assembledwith the gears for 13
FPM. Both planingand moldingcan be done at this set-
up.For the increased feed rate -- 26 FPM, the gears
have to be changed. Gears for 26 FPM are in the hard-
ware bag.
To change gears:
• Loosen and removenyloninsert Iocknutsi(Figure15,
KeyNo. 28).
• Slide two screwdrivers,one on eitherside ofthe 40T
moldinggear (Figure 15, Key No. 31).
• Gently pushthe screwdriversand slide g_ar off the
gear shaft (Figure 15, KeyNo.29).
• Leavethe key (Figure15, KeyNo.27) inthe gear shaft.
• Removethe 21T moldinggear (Figure 15, Key No. 26).
• Positionthe gears for 26 FPM on the gea'rshaft,
aligningthe keyway.
• Gently push it into place.
• Replace andtighten nyloninsertIocknuts
V-BELT ADJUSTMENT
Refer to Figures 14,15 and 16, pages 14, 16 and 18.
Inadequate tension in the V-Belt (Figure 15, Key No. 54)
willcause the belt to slipfrom the motorpulley(Figure
14, Key No. 9) or ddve pulley (Figure 15, Key No.53).
Toadjust V-Belttension:
• Loosen and removefour sockethead bolts (Figure
16, KeyNo. 5) on cover (Figure16, Key No. 2)
• Remove cover.
• Loosen two sockethead bolts(Figure 16, ,KeyNo. 48)
thatgo throughthe tensionplate(Figure16,gay No.39).
• Tightentwo sockethead bolts (Figure 16, Key No.
48) that go intothe indenton tensionplate to tension
belt. Belt istensioned properlywhen moderate finger
pressure applied to the midpointof belt produces_"
deflection.
• Tighten twosockethead bolts (Figure 16, Key No. 48)
that gothroughthe tensionplate.
• Replace coverand tightenfourbolts(Figure 16, Key
Nos. 2 and 5).

WOODGRAIN
For an improved surface finish with minimaltearout,
always plane or mold the workpiece with the grain. The
workpiece should be fed into the planer/molder so that
the knives or bits are traveling with the grain as the cut-
ters finish the cut. The grain should be angled up
toward the rear of the workpiece as it is fed into the
pLaner/molder.
PLANING
WARNING: Alwaysturn the planer/molder offand dis-
connect it from the power source whenever knife cover
is removed. Never operate planer/molder without the
knife cover properly secured.
The planer/molder is supplied with planing blades mount-
ed in the cutterheedand the infeed and outfeed rollers
adjusted to the correct height. The planer/molder is capa-
ble of working at two different feed rates.Feed rate refers
to rate at which lumber travelsthrough planer/molder.
Planing can be done at 13 FPM for an improved surface
finish or 26 FPM for faster planing (see Feed Rate
Adjustment).
• Adjust the table height to produce the depth of cut
desired.
• Stand to side whichthe handwheel was attached.
• Lift edge to infeed side ofthe table by grasping
edges of board at approximately middleof length.
• Boards longer than 24" should have additional sup-
port from free standing material stands.
• Position the workpiece with the face to be planed on
top.
• Gently slidethe workpiece into the infeed side of the
planer/molder until the infeed roller begins to
advance the workpiece.
• Let go of the workpiece and allow automatic feed to
advance the workpiece.
• Do not push/pull on workpiece.
• Move to the rear and receive planed lumber by
grasping it in same manner as it was fed.
CAUTION: Do not stand directly in line withfront or
rear of planer/molder.
• Do notgrasp any portion ofboard which has not
gone past out-feed roller.
• Repeat this operation on all boards which need to be
same thickness.
• Move to the rear and receive planed board by gently
pushing itup when the infeed rollerlooses contact
with the board.
• When planing more than one board of the same
thickness, butt boards togetherto avoidsnipe.
KNIFE HEIGHT ADJUSTMENT
Refer to Figures 6 and 15, pages 7 and 16.
WARNING: Disconnect planer/molderfrom the power
sourceand turn the planer/molderOFF before attempt-
ingto adjustor replacethe cuttingbitsor knives,or per-
forming any adjustment or maintenanceto the
planer/molder.
A knife height gauge is providedfor usewhen replacing
or adjusting the planingknives (Key No. 40).
• Unplugthe planer/molderand turn itOFF.
• Remove the knifecover (Key No.4)
• Loosen all the set screws(Key No. 42) on all ofthe
gibs (Key Nos.41 and 43) inall 3 cutterhead slots.
• Using the brass punch,tap all the gibsdown intothe
cutterhead slot.
• Make sure the gibs are loose and can be moved.
• Remove the old knives, all gibs and spacers (Key
No. 44).
• Make sure the cutterhead slots and gibs are clean.
• Install the new planer knives and replace gibs and
spacers.
• Tighten the gibset screws only enough to holdthe
gibs and knivesin position.
• Make sure there is nogap betweenthe gibs,and the
spacers are in place.
• Place the knifeheightgauge on one end of the knife
and adjust the jack screw untilthe knife justcontacts
the tab in the middle ofthe gauge (see Figure 6).
• Adjust both ends ofall three knives in a similar man-
ner untilall of the knivesare at the same height.
• Tighten the gibs slowly,movingfrom one cutterhead
slot to the next, until allthree knivesand all gibsare
tightand secure.
NOTE: The knivesmay creep up as the:gibsare tight-
ened. Lightlytap on kniveswith a piece of hardwoodto
positionknivesagainst jack screws if needed.
Knife Height Gauge
AVOIDING SNIPE
Surface that the planer/molder will produce will be
smootherif shallowerdepth of cut is used.Snipe refers
toa depressionat eitherend of board caused by an
unevenforce on cutterheadwhen work is enteringor
leaving planer. Snipe will occur when boards are not
supported properlyor when only one feed rolleris in
contactwith work at beginningor end of cuLTo avoid
snipe:
• Gently push the board upwhile feeding the work
untilthe outfeed roller starts advancing It.

POSITIONTHE CHIPBREAKER
Refer to Figure 15, page 16.
The chipbreaker (Key No.2) is used to help remove
wood chipsfrom the cutter bitsand kniveswhile planing
or molding. Adjustthe chipbreaker every time the cut-
tingtoolsare changed or adjusted.
The chipbreakershould be positionedas closeto the
cutterheadas possiblewithoutcontactingthe cutter bits
or knives. Loosen the three hex head bolts (Key No.3)
that hold the chip breaker and position itas close to the
cutterhead as possible, rotate the cutterhead by hand to
ensurethat there is no interference with the chipbreaker.
Secure the chipbreaker by tightening the three hex head
bolts. Replace and secure knife cover.
MOLDING
Molding, also knownas miliworkor trim,can be defined
as a stripof wood milled with a plain or decorative sur-
face which is continuousthroughoutits length.
• To get superior moldingfinish, workpiece must be
planed and presized priorto molding.Always presize
the workpiece to '/_,"of the final thicknessprior to
molding.
Certain moldingprofilesrequireouter edge clean-up.
When usingsuch profilesthe workpiece must be pre-
sizedto ¼" larger than the final width.This will allow ',_,"
for clean-up on either side.
Certain molding profilescut only the edge of the work-
piece.When using such profilesworkpiece mustbe pre-

Refer to Figures 7, 8 and 15, pages 8, 9 and 16.
NOTE: The cutter bits arc mounted in the center of the
cutter head (Figure 15, Key No. 39) usingthe 2" bit gibs
(Figure 15, Key No.43) provided.The cutterbits and
the planing blades (Figure 15, KeyNo. 40) are mounted
in the cutterhead at the same time so that planingand
moldingoperations can be done with the same set-up.
The knife settinggauge (see Figure 7) isused when
mountingthree piecemoldingbitsin the planer/molder
cutterhead.The gauge alignsthe bits inthe cutterhead
so that all three bitscutthe workpiece inthe same posi-
tionprovidingprecisecutsand improvedsurfacefinish.
• Turn the planer/molder off and unplugthe
planer/molderfrom the power source.
• Remove the knife cover and chip deflector (Figure
15, Key Nos. 4 and 6).
• Using the 6mm socket head bolt (Figure 15, Key No.
5) used to mount the knife cover, mount the knife
setting gauge to the top of the planer/molder as
shown in Figure 7.
• Position the knife setting gauge so that the molding
bits are positioned incutterhead as required. Tighten
the 6mm socket head bolt.
• Loosen two set screws (Figure 15, KeyNo. 42) on
the 2" bit gib (Figure 15, Key No. 43) locatedin the
center of the cutterhead.
• Use the brass punch in the hardware bag to gently
tap the gibdown into the cutterheadslot.
• Tap untilthe gib isloose and can be moved.
• Remove the 1" spacers (Figure 15, Key No.44) as
needed.
• Be surethe cutterhead slotand gibs arc clean and
free ofany dirt, grease, chipsor burrs.
• Place the cutter bits in the cutterhead slo! in place of
the spacers.
• Insertthe first cutter bitto be mounted between the
bit gib and planer knife.
• Slide thecutter bit against edge of the cutter bit set-
ting gauge and tightenthe cutter bit/bitgib combina-
tion in the cutterhead.
To mount more than one cutter bit ineach cutter-
head slot, for example, tongue and groovecutter bits
(23302), additionalset of three bit gibs isi'equired.
Use replacement parts list,page 17, Key No. 43 to
order.
• Remove oneor both cutterhead gibs (Figure 15, Key
No.41) as needed after looseningthe set screws
(Figure 15, KeyNo. 42) and tapping gibs down.
• Place the bit gibin thecutterheed slot at the desired
position.
• insert the cutter bitbetween the bitgib and planer
knife,and tightencutter bit]bitgibcombination.
• Rotate the outterhead and mountthe remainingcut-
ter bits usingthe knifesettinggauge to align bits.
• Be sure all bits and gibsare tight and secure.
• Remove the knife settinggauge and replace the

Figure 9 - Cutterhead with Pattern Knives
The planer/molder cutterheadwill accept multiplepat-
tern knife set-ups at one time. For example, a pattern
knife and its relief knives can be mounted at the same
time so that the relief and the molding can be done with
one gib set-up.To mount pattern knife, the gib supplied
with the pattern knife must be used. To mount back
relief knife, the bit gib and 1" spacers (Figure 15, Key
Nos. 43 and 44) must be used.
• Installthe firstpattern knife inthe cutterhead slot
withthe propergib and tighten the knife/gibcombi-
nation.Rotate cutterhead. Use knifeSettinggauge
and installthe two remainingpattern knives, one in
each cutterhead slot.
• Installthe first back relief knifein the cutterhead slot
withthe bit gib and 1"spacers.Tightenthe knife/bit
gib combination.Rotate cutterhead. Use knifesetting
gauge and installthe two remaining back relief
knives,one in each cutterhead slot.
• The feed rollersmustbe lowered after the back relief
cut for moldingoperation.See "Feed Roller Adjust-
ment"below.
• Make sure all knivesand gibs are aligned,tightand
secure.
• Turn the cutterhead by handand make surethere is
no interference withthe knifepath.
To installmore than one pattern knife in each cutter-
head slot, for example, crown and bed knivesor tongue
and groove knives, an additional set of three gibs is
required.
Make sure the chipbreakerpositionisappropriatewith
all the pattern knives. Be sure to replacethe knife cover

FEEDROLLERADJUSTMENT
Refer to Figures 10, 15, and 16, pages 10, 16 and 18.
The planer/molder feed rollerscan be raisedor lowered
as needed. The infeedand ouffeed rollersare set _6"
below the cutterheed (not the knives)at the factory for
planingoperation.The infeed and ouffeedrollers have
to be set _e" below the cutterheed for moldingopera-
tion usingthe pattern knives.Feed rollers must be
adjusted properlyfor smoothfeeding of the work.piece.
NOTE: Never lower infeedand oufteed rollersbeyond
_o" lowerthan the cutterheed.This willcause severe
stresson the gearbox and rollersystem.
To adjust feed roller heightfor molding:
• Make two 3 x 1½ x 3½" blocks and mark them as
cutterhead blocks.
• Make two 2"A, x 11/2x 3½" blocks and mark them as
molding blocks.
• Make sure the blocks are made to the mentioned
size.
• Turn handwheel (Figure 16, Key No.22) and lower
the table (Figure 16, Key No. 20) to allow cutterhead
blocks to slidefreely between the table and the cut-
terhead. Cutterhead may have to be turned by hand
to rotate knife out of the way.
• Place the 3" portion of cutterhead blocks beneath
the cutterhead, one on each side. Adjust table height
so the cutterhead block just makes contact with the
cutterhead.
• Do not raiseor lower the tablefrom nowon untilall
other adjustmentsare made.
• Place the 2"/_6"portionof moldingblocksbeneath
the infeed roller,one on each side.
• Loosen the large hex nuts ( See Figure 10 and
Figure 15, Key No. 10) on both sides ofthe infeed
roller using the wrench provided.

Threaded Bushing
(Do not Adjust) "_'r_Large Hex Nut
Figure10 - AdjustingFeed RollerHeight
• Using the same wrench,turn threaded bushing
(Figure 15, Key No. 9) clockwiseuntilthe infeed
rollerjust makes contactwith the block.
• Tighten large hex nutand repeat this process with
the other side of the infeed roller.
• Move moldingblocks beneath the outfeed roller and
repeat the process.
• Make sure that the large hex nutsare tightenedafter
adjustment.
• Remove the cutterhead blocksand moldingblocks
and retain them for future use.
The feed rollers should be raised to their original posi-
tion when the moldingoperationis done and at all
times when planing.
To raise rollersto original position:
• Make two 21'Ae" x 1½" x 3½" blocksand mark them
as planing blocks.
• Adjust the feed rollersheightin the same manneras
for the moldingusing 2'_" portionof the blocks.
• Retain the blocksafter adjustmentfor future use.
AUXILIARY TABLE
Some of the cuttingbits and pattern knives are designed
tocut all of the way throughthe workpiece and _/;,"
beyondthe workpiece.
Thisproducesa smooth edge and final sizing of the
workpiece.When usingthese bitsor knives,an auxiliary
woodtable must be mountedon the cast irontable to
preventdamage to the table and the bits or knives.
The auxiliary table shouldbe made from smooth 3A"
particle board (12¾" wide and 31W' long) to providea
smoothsurface for the workpiece to slideon.
NOTE: Auxiliarytable is 12" longerthan the bast iron
table to allow 6" overhangin the front and rearfor long
workpieces.
The particle board must be mountedon the cast iron
table with four _a x 1"flat head screws,washers and
nuts(not included).Be sureto countersinkthe mount-
ingholeson the auxiliary table for the flat head screws.
The screws must be positionedbelow the surface of the
auxiliary table to preventdamage tothe workpiece.
GUIDE FENCES
When molding,the workpiece mustbe guided into the
moldingcutterbits or knives properlyin order to pro-
duce the desired shape and size molding. Using prop-
erly adjusted guidefences assures the workplece pass-
es the moldingcutters/knivesinthe same position
usingmultiplepasses.
Guide fences shouldbe made from smooth,straight
hardwood.Guide fences should be the same lengthas
auxiliarytable (311/4")and 2" wide.Cut the guide fences
14"lower than the maximum thicknessof the final work-
piece profile.The guidefences must be notchedto
clear the infeed/ouffeedrollersand anti-kickbackpawls.
See Figure 11 on page 11for dimension.
To mount guide fences to table/auxiliary table:
• Installmoldingcutter bits/knivesinthe cutterhead.
See =Installing CutterBits=and =Installing the Pattern
Knives".
• Lowerthe table and carefullyturn cutterheadby
handso that one cutterbitJknlfeis at the lowest point
of the cuttingedge.
• Positionthe workplece beneath the cutter bit/knife.
