2. ADJUSTINGTABLE TOP PARALLELWITH ARM
To obtainaccuratewoodworkingresults, itis essentialthat
the table is completelyparallelwith the arm. The following
instructionsexplain howtodo this:-
1. Prepare the baseframe forthe tableboards by
setting the2 angled support brackets (A-Fig. 1) on
eachside ofthe frame so that the securingbolts (B)
and(C)areatthe mid-point inthe slottedholes. At
this stage the boltsshouldonly be finger tight.
NOTE: Some models feature location pins which pre-
set the position of the brackets on the main frame.
On these models the bolts can already be tightened,
but you should still make the following checks. If they
indicate the location pins are wrongly positioned: tap
the pins out with a hammer and adjust via the slotted
holes in the support brackets.
Fig. 1
Usethetipofthe motorspindle toactasa gauge to
checkthat the2 supportbrackets areonthe sameplane,
as follows:
(i)
(iv)
(v)
(vii)
Rotate the elevatinghandle and raise thearm
enough to allow the motor to turn 90° into the vertical
position.
Releasebevellatch and bevellock and turn the
motor body until itis vertical.When it reaches the
verticalpositionpresshome the bevellatch so that
the motor is lockedintoposition.
Release thearm clamp lever andtherip lock and
bring the motor toits fully forwardposition onthe
arm.
Rotate thearmto bring the motor shaft toa position
directlyover the left tablo supportbracket.
Carefully lower the motor, by turning the elevating
handle, until thetipofthe motorarborjusttouches
the supportbracket as shown.(Fig. 2)
Tighten thenut (C), rotate thearmtoits45° position
left and move the yokeassemblybackalong thearm
until the shaft is againover the supportbracket (Fig.
3).Ifthe motorarbordoes not justtouch the support
bracketherealso,gently tapthe bracket upor down
as required and thentighten nut(B) (Fig. 1). Having
tightenedboth (B)and (C). check once morethat the
motor arborjusttouches the uppersurface ofthe
left-handsupportbracketover its entirelength. Ifit
does not, loosen the nuts and repeat the above
procedure.
Now move thearmtothe right ofthe machine and
repeatthis procedure to correctly secure the right-
handsupportbracket.
Carry outa finalcheck,running thetipofthe motor
arbor along thetopof bothbrackets and makesure
that all nuts are completelysecure.
Now adjust the centraltablesupportstrip inthe same
way so that itis perfectlylevelwith thetwo side
support brackets.(Fig. 4).
N.B. Itis important notto change the height ofthe
arm duringthisadjustment procedure.
After completing the aboveadjustment,return the
motor tothe horizontalposition.

3. ASSEMBLY OF WORKTABLE ONTO SUPPORT BRACKETS
Note: The worktablecomprises 5 elements(Fig. 5):
a largefixed portion (F) whichattaches to the front of the
base frame, a woodenfence (M) againstwhich the
materialbeingworked is held and threemovablestrips
of tablewhich are used to adjust the position ofthe
fence relative tothesaw blade to ensure the different
types/depth ofcutcanbe carried out withsafety.
(i) Secure the frontboard (F)tothe support brackets
using the slotheadedbolts (G)andthe relative
washers and nutsmakingsurethat the holes inthe
middle ofthe boardlocateover the centralsupport
flange inthe baseframe.
Note: The additionalholes onthe left handside ofthe
table arefor mounting the tablesideextension.
(ii) Mount the sawblade(see Fig.6) makingsure the
lower teethpointtowards the back ofthe machine.
Tighten the blade onthe shaft using the larger ofthe
alienkeysprovided to hold the shaftsteady while
tightening the arbor nut anti-clockwise(left-hand
thread) with the largeopen-endedspanner.
(Note that the brassarbor nuthasan innercircularring
rather thanbeinghexagonalacross its full width - thenut
shouldalways be mountedwiththisinnerringfacing the
motor).
(iii) Youcannow checkthat the frontboard is flat and
parallel tothearm across its entire width. Todo this,
lower the blade so that the bottomtoothjusttouches
the front board onthe front left handside.Then,with
the mitrelatch and clampreleased,swing thearmso
that the bladeskims thetopofthe boardacross its
width. Ifthetipofthe blade, does not just touch the
board alltheway across,thenwith a screwdriver
adjust the frontadjustingscrew inthe middle ofthe
board upor downuntilthat isthe case.Thenmove
the sawbladebackalong thearmand adjust the rear
adjusting screw inthe sameway.
(iv) Mount the bladeguard as follows:-
1. Release the bevellatch (14) and bevelclamp(12)
and tilt the motor and bladeabout 30°tothe left.
2. Loosen the lockingscrew (P) (Fig. 7)and turn the
retaining bracket (N) anti-clockwiseuntil the right
hook ofthe rear blackguard (F)canbe lifted free of
the supportlug.
3. Slide the blackguardroundclockwiseuntil it reaches
the dottedlineposition in the illustration.
4. Now lower the guardover the sawblademakingsure
that the hingedplasticsectiondoes not foul against
the motorshaft and that the lowermetaledge onthe
other side ofthe guardengagessatisfactorilywith the
lugs onthe motorhousing - thiswillensurealsothat
the hole onthe upperguardbracketlocatesover the
retentionbolt ontopofthe motor.
Place the washer onthe bolt and secure the wing nut
to hold the guard firmly.
NOTE:Whenever you remove the guard, resecure the
wing nut and its washer to the retaining bolt on
top of the motor housing so that no parts can
be lost.
ALWAYS REPLACE THE GUARDBEFORE
SWITCHING ON YOURMACHINE AND
REMEMBER THATEVEN A STATIONARY
SAWBLADE IS SHARP SO TAKECARE NOT
TO CATCHYOURSELF ONTHE TEETH.
6. Slide the black guard (F) backroundanti-clockwise

4. CHECKS AND ADJUSTMENTS TO ENSUREACCURACY
4.1 Checking the
Crosscut Travel is
90°tothe Fence
NOTE: In carrying out these checks and adjustments
you may find it more convenient to remove the
sawblade guard but remember that even a
stationary sawblade is sharp so take care not
to catch yourself on the teeth.
With the mitrelatch (19) engaged,lock the clamphandle
(18) so that the sawblade is positioned fora straight 0°
cross- cut.Release therip lock (7)and push thesaw
carriageback so that the sawblade is just in front ofthe
fence.Then, by turning the elevatinghandle,lower thearm
so that the sawbladealmosttouches the surface ofthe
table in front ofthe woodenfence.
Youarenowina position to checkthat the bladewill cuta
line at90°tothe fence.Proceed as follows:-
(i) Place a rectangularpiece of board in front ofthe
fence alongside the blade andlaya square flat on
topofitas shown in Fig. 9 with one side flat against
the fence andthe otheralongside the blade,
(ii) With the lowerleft-handpart ofthe bladeguard
raised (oryoumay find it easier to remove the guard
completely)pull thesaw carriageforwardawayfrom
the fence and checkthat the tooth onthe blade
protrudingfurthest tothe left (it will be either onthe
leading or trailingedge ofthe blade)staysparallel to
the square asyou pull thesaw bladepast the square.
If itisnot runningsquare, thearmisnotat90°tothe
fence.
Note: At thisstage, donot worry ifthe face ofthe
bladeitself isnot parallelwith the square.
This will be adjustednext. Wearenow
merelycheckingthat the line ofthe blade
across the table isat90°tothe fence.
Fig. 9

Fig. 10
To Adjust the Crosscut Travel
(i) With the mitrelatchengaged inthe0° position.
slacken the mitreclamp.
(ii) Loosen the locknuts on each side ofthe arm. as
shown in Fig. 10.
(ill) Release the mitrelatch and depending on which way
the arm needs to move to give the true 90° crosscut
required,loosen and tighten the adjusting flanges on
either side ofthearm (Fig. 11) ifthe front ofthearm
needs togotothe left, loosen the adusting flange on
the right ofthearmand tighten the flange onthe left.
If the opposite isthe case, andthearm needs to
move tothe right,loosen the adjusting flange onthe
left and tighten the flange onthe right. Adjust the
flanges a little ata time and re-engage the mitre
latch and clamp and check the crosscuttravel ofthe
blade relative tothe fence with a square. Donot
overtighten the adjustingflanges orthe mitre latch
will betoo stiff to operate easily.
(iv) Once satisfied that the crosscuttravel is accurate,
retighten the locknuts on eachside ofthearm(asin
Fig. 10).
(v) Adjust the pointer onthe mitrescale so that it
registers 0°in this position.
Fig. 11
4.2.Checking the
Saw Blade is Parallel
to theArm Tracks.
Thischeck isto ensurethat, inthe straight 90° cross- cut
position, the blade runstrueacross the table and does not
run "dogfashion"(Fig. 12). Ifthe blade is incorrectly
adjusted in thisway. it willproduce a cut widerthan the
setofthe blade(distanceacross the tips ofthe teeth). It
would alsotend to causescorchmarks onthe timber
being cut.
To Check
(i) Place a square against the fence asin Fig. 9 and,
with the sawbladejust in front ofthe fence inthe90°
crosscut position (lock itin thatposition with therip
lock) checkthat the left handface ofthe blade is
parallel tothe square. Ifitisnot parallel, adjustment
is necessary.
To Adjust
The illustration (Fig. 13) shows the components ofthe
yoke assembly. The precisealignment of rollerhead (8)
withyoke (17) is made possible by collar (I) which is fixed
to the yoke bythe lockingnuts(J).
(i) Firstly, graspyoke in bothhands and check itfor
movement left or right, if there is movementtighten
nut (H) whichincreases the frictionbetween therip
locatingslide bar(K)and nylon block (L).
(ii) Then, ifthe blade is still not parallel tothe square.
release the yoke clamp (10) and loosen the locknuts
(J) (Fig. 13/13a) and turn yokeslightly to left or right
until the blade isin factparallel tothe square and
therefore alsoparallel tothearm tracks.Then tighten
all nuts.
(iii) Havingadjusted the bladeparallel tothearm tracks
in this way, release therip lock and pull thesaw
carriage forward. Raise thesaw bladejustabove the
surface ofthe table by turning the elevatinghandle.
(iv) Now release therip locating slide barandthe yoke
clamp and thenrotate the yoke 90°so that the blade
is facing the fence and lock it into that position with
the slide barandthe yokeclamp.Thenpush thesaw
carriage backwardsuntil the blade is restingagainst
the fence.
If the blade is completelyflat,across its faceagainst
the fence, this will confirm that thesaw will perform
accurate parallel rip cutting.
Fig. 12
Fig. 13
Fig. 133

If byany chance the blade does notlie flatagainst
the fencethenreturn ittothe0° cross-cutposition
and repeat the aboveadjustmentprocedure(making
bladeparallel toarm tracks).
4.3 Checking the
Blade is Perpendicular
to Table
Fig. 14
4.4 Adjusting
Roller Head Bearings
toArm Tracks.
(iv)
For accuratewoodworking, itis alsonecessarythat the
sawbladecuts a precise 90° vertical line when intended to
doso.
To Check
With thearminthe cross-cutposition andall
latches/Clamphandlesengaged,place a steelsquarewith
one edge onthe worktableparallel tothe fence(Fig. 14)
andthe otheredgeagainst the left face ofthe sawblade
(makesure the squarepassesbetween the teeth ofthe
blade and restsagainst the innerface). Ifthe blade isnot
thencompletelyflatagainst the square, it follows that itis
also notat rightangles(90°) tothe worktable.
To Adjust
(i) Removebevelpointerdisc (A)by removing thetwo
screws (B)in Fig. 15 and re-engage the bevel latch.
Loosen thetwo outside alien screws (Fig. 16).
Tilt the motor left or right until the blade is flat against
the square.
Firmly retighten the alien screw(s) L.
NOTE:It may be necessary to loosen the centre alien
screw (M) slightly before the motor will tilt. If
you do so, be sure to secure it again firmly
before replacing the bevel pointer disc.
(v) Replace the bevelpointerdisc.
In mostcases the aboveadjustmentswill beall that are
necessary to enableaccurate sawing with your DeWalt
Radial Arm Saw.
However, in time itis possiblethatplaymightdevelop in
the adjustment ofthe roller head bearings tothearm
tracks which will causeinaccuracy.
The rollerhead is suspended by threespecialbearings
(Fig. 17). Twoof these are mounted on straightbearing
shafts (Q)andthe third is mounted onan eccentricshaft
(R).
If there is lateralmovementbetween the bearings andthe
arm tracks,(and you will be able to feel it,if there is)
proceed as follows:
(i) Pull the yokeassemblyforward totheendofthearm
tracks and lock itin positionwith therip lock.
(ii)Remove therip scale pointer onthe right ofthe yoke
assembly by withdrawing thetwo Phillipsscrews.
With therip scalepointerremoved, you haveaccess
with an alien keytothe locking screw as shown.(Fig.
18). Havingslackenedthisscrew,alsoloosen the
13mm lock nut(J) immediatelybeneath it. (Fig.19).
Then release therip lock and with an alien keyvia
the accesshole inthe underside ofthe yoke(Fig. 20)
rotate the eccentricbearing (R) slightlyuntil itis
sufficiently in contactwith thearm track to ensure
that all3 bearingsrotate asthe yokeassembly is
movedbackwards and forwardsalong the arm. Ifyou
find it difficult to feelwhen the adjustment is correct,
you may find it easier ifyou remove theArm end-cap
so that youcanseethe3 bearingsrotating inthe
tracks. Oncesatisfiedthat the adjustment is correct,
retighten the 13mm lock nutand then the horizontal
alienscrew and replace the ripscalepointer.
NOTE: Thetopand bottomedges ofall three
bearings should bein contact with thearm tracks
over their entirelength andthe roller headassembly
shouldmovefreely but withoutside-play.

4.5 AdjustingBase
to Column
Note: From time to time, youmay find that there isa
build-up of dust inthearm tracks oronthe
bearings - especially after ripping. To maintain
accuracy and ease of operation, it will be
necessary to clear this dust. This canbe done as
follows:
(i) Remove thearm end-cap.
(ii) The yokeassemblywill then come outattheendof
the arm.
With a clean, dry clothwipe thearm tracks along
their entirelength to remove all dust and grease
(Fig. 21).
With a vacuumcleaner and cloth, clean offall dust
onthe3 bearings ofthe yokeassembly. White spirit
canbe used if necessary to remove compacted dust.
(v) Remount the yokeassembly inthearm tracks and
replace thearmend cap,makingsure all retaining
screws are tightly secured.
CAUTION:Neverattempt to lubricate the surface of
thesebearings orthearm tracks, as this can
causeprematurewear and inaccuracy.
The followingadjustment will alsonormally be
unnecessaryunlessyourPowershop has beenmoved
frequently fromsite to site.
If. after, the mitrelatch is engaged inthe0° straightcross-
cut position andthe mitreclamp is secured,there is still
side, or up-and-down, movement atthe front endofthe
arm caused bythe columnmoving inits base, the
followingadjustment is necessary:
(i) Loosen the locknuts (Uin Fig. 22)onthe2 brass
alien screws onthe left ofthe base(lookingfrom the
rear) and thenslacken the innerbrassscrewswith
an alienkey.
(ii) Turn the elevatinghandle to move the column upand
down. If base is seen tobe slackaround the column,
adjust by unscrewing thetwo nuts W (Fig.22a)until
the correct fithas beenachieved.Avoidbinding by
overtightening.
If the base istoo tightaround the column,adjust by
unscrewingnuts (X)and tighteningnuts (W)for
correctfit.
(iii) Retighten the brassscrewsagainst thekeyonthe
back ofthe column andsetthe locknuts to hold
them in position.
CAUTION: After carrying out thisadjustment,check
again the straightcross-cuttravel isat90°
to the fence - and adjust if necessary.

5.2 Adjusting the
BladeGuard
See instruction 3. (iv)
—ForRip Cuts:
(i) Loosen the2 knobs (H) (Fig. 23)and slide the riving
knifebracket (B) downuntil thetipofthe riving knife
(C) is approximately 10mm (%") from the surface of the
machine'sworktable. The distance ofthe riving knife
from the blademust be between 1-3mm. (adjust by
loosening the screws (G)and sliding the knife left or right
within the bracket slots).
(ii) Loosen the knob (Q)onthe back ofthe guard and
lower the bracket (D) until the centralspring onthe
bottom ofthe bracketjust touches the surface ofthe
timber(i.e.when the tips ofall anti-kickback fingers
(L) are positioned at about
1/8"
below the surface of
the woodbefore you start to feed the timber into the
blade). Once the anti-kickbackfingers have come
into contact with the surface ofthe timber, they
should beatthe angleindicated.
Important: Itis essential for saferip-cuttingthat the anti-
kickbackfingers are correctlypositioned •
they prevent the tendency ofthe blade to
throw the timberbacktowards the operator.
Notethat the alien screwmounting the anti-
kickbackfingersonto its supportbracket can
be loosened to allow the kickbackfingers to
be angled for bevel-ripping.
It is alsoimportant tousethe rivingknife inits
correctpositionwhen ripping to prevent the
timber binding onthe blade.
— For Cross-Cutting:
Neither the rivingknife northe anti-kickbackfingers are
needed for cross-cuts, so makesurethatthey are both
adjusted upoutofthe way.

6. MAKING A TRIAL CUT
.;-•
Having completed the aboveadjustment procedure, itis
now time to make a straightcross-cut ina piece of timber.
Note: If, when you were setting up your machine, the
saw carriage travel wasnotas smooth asyou
would expect, that probably meansthere are
pieces of polystyrene packing stuck either tothe
arm tracks ortothe3 bearings onthe yoke
assembly. With a clean, dry cloth wipe both the
tracks andthe bearings to eliminate this.
6.1 Wiring uptothe
MainsSingle-Phase240vModels
Connect a standard 13 amp rubber-covered earthed plug
to the cableattached tothe machine as shown inthe
illustration.Makesurethat the cable clamp is holding the
outersheath ofthe cablesecurelybeforefixing thecapto
the plug.
Plug inand switch onatthe mainssocket.
Three-Phase 415v Models
Three-phasemachinesshould be wireddirectlyinto the
mains bya suitablyqualifiedelectrician.
6.2 Making theCut
(i) With the mitre lock engaged, lock thearm clamp
handle so that the sawblade is positioned fora
straight 0° cross-cut.
(ii) Release therip lock and push thesaw carriageback
so that the sawblade is behind the fence inits
correctpositiondepending onthe materialthickness
(See Fig.25).
(iii) Now, by turning the elevatinghandle,lower thearm
so that the sawbladealmosttouches the surface of
the table.Place the piece of timberagainst the front
of the fence.
(iv) Gripping the switchhandle,press the right-handside
of the push-buttonswitch with the thumb ofthe
samehand.
(v) Once the sawblade has reached maximumspeed
(after a shortspeedbuild-up of2 or3 seconds)
rotate the elevatinghandle to allow the blade to just
cuta shallowgroove or kerf inthe surface ofthe
table.
(vi) Now pull thesaw blade slowlytowards youso that it
cuts a verticalslot inthe woodenfence and through
the piece of timber, and then push the carriage back
to the column.
(vii) Now switch offthe machine by pressing the left-hand
side ofthe switch.
With a set squarecheckthat thecutin yourpiece of
timber isa true 90°in eachplane. Ifitis not,then
furtheradjustment is necessary and refer back tothe
appropriateinstruction.
Note: The control switch on your Powershop incorporates
3 very useful feautures:
(1) It "locks on"so thatthumbpressuredoes not need
to be maintained — usefulwhenripping(obviously)
but alsoadvantageous for left-handoperators.
(2) There is motoroverloadprotectionbuiltinto it
removingpowerfrom the motor inthe event ofit
overheating.
(3) Ithasa "no-voltrelease" so that if there isa removal
of power the switch hastobe deliberately re-
actuatedbefore the motor will run.

7. SCALE ADJUSTMENTS
7.1Rip Scale Therip scale is located onthe rightside ofthe radialarm.
When the motor is positionedwith the bladefacing the
column,that is called the "in-rip" position and your
materialmust befed through the bladefromright to left.
When the motor is positionedwith the bladefacing the
operator, that is called the "out-rip"position andthe
material must befed from left to right.
The pointer indicating the rippingwidth onthe scale is
adjustable as follows:
1. Place a board of known width (say about 24cm) against
the fence inits "rip"position(SeeFig.25).
2. Position the motor inits "out-rip"position (blade
towards the front ofthe machine) and move the yoke
assemblyalong thearm until the bladejust touches the
forward edge ofthe material.
3. Loosen thetwo screws onthe pointerassembly and
move the pointeruntil the edge ofthe "out-rip" pointer
lines up with the knownwidth ofthe board onthe lower
scale.Tighten thetwo screws.
4. Now remove the board and place the motor inits "in-
rip"positionwithoutmoving the yokeassembly.
5. The "in-rip"pointershould now line up with the zero
position onthe upper scale (adjust if necessary). The
position ofthe bladehereindicates the ideal location
for the fencewhen"in-ripping".
Note: Itis generallygoodpractice to check the width of
cut with a taperatherthanrelyingsolely onthe
scale,although the scale canbe usedwith
complete confidence when making several cuts at
differing widths(i.e.+5mm or -7mmrelative tothe
first cutting width).
7.2 Bevel Scale
The bevelscale is located onthe front ofthe motor'
beneath the switchhandle.When the blade is positioned
for a verticalcut, the pointer should beat zero onthe
scale. To adjust,loosen the screwsretaining the pointer
disc, and move the disc until the pointerpoints to '0' and
thenretighten the screws.
7.3 Mitre Scale
The mitrescale is located onthetopofthearm beneath
the elevating handle. Ontopofthearmisa pointer which
canbe adjusted to alignwith the '0'when thearmhas
beencorrectlypositioned and clamped fora straight
cross-cut. The scale is thenmarked 0°-50° to left and
right. The mitrelatchengageswithmachinedlocations to
provideaccurate 45°—0°—45° positioning.

8. CLAMPHANDLEADJUSTMENTS
(i) The Mitre Clamp handle (18) may need tobe
adjusted ifits securepositionmeans it hinders useof
the elvatinghandle. In such a case, simply slacken
the clamphandle and push it into the casting so that
thenutonthe other end protrudesfrom its
surrounding casting. Youcan thentighten upthenut
half a turn and pull the clamphandleback outso that
when itis again retightened it does not obstruct the
elevating handle.
(ii) The Bevel Clamp handle(12) maybe adjusted in the.
same wayasin(i) above butyoumay find it easier
todoso with the motor inits verticalposition.
(iii) The adjustment ofthe yokeclamp isa little more
involved.
If you find that the YokeClamp has insufficient
movement to satisfactorily clamp the yokesecurely,
adjust as follows:
(a) Remove the arm end-cap.
(b) Remove the complete yoke assembly from the arm
tracks.
(c) While levering the spring steel locking flange
downwards with a screwdriver (as shown in Fig. 26)
so that it will pass over the lug on the yoke casting,
turn the central bolt in the top of the yoke with a
large screwdriver so that the locking flange
underneath moves on one segment past the lug.
(d) Having removed the small screwdriver used as a
lever, check that the clamp does lock satisfactorily
within the movement arc available and then return
the yoke assembly to the armtracks.
NOTE: While the yoke assembly is removed from the
arm, take the opportunity to clean the bearings and
the arm tracks with a clean dry cloth.
(e) Replace the arm end-cap.
Fig. 26
9. HINTS ON GENERALCARE OF YOURPOWERSHOP
1. Keep the machine clean for efficientoperation. A
build-up of dust inthe immediatevicinity ofthe
machinecould be hazardous and lead to inaccuracy.
2. When changing or remounting the sawblade,make
sure that the blade and adjacentflanges are clean
before securing.
3. Keep the worktableclear of sawdust.Just a small
amount of dustbetween the fence andthe material to
be cut couldcauseinaccuracy.
4. Fromtime to timewipe thearm trackswith a clean,
dry cloth to eliminatedustbuild-upwhich can ensue
particulary after a lotofrip cutting or sanding. To
clean the arm tracks and the 3 yokebearings, you
may find it easier to detach thearmendcapand
remove the yokeassemblycompletelyfrom the
tracks. White spirit canbe used if necessary to
remove compacteddust.
If you remove the yokeassembly,whenreplacing it
be sure to tighten the retainingscrews inthearmend
cap securely.
5. Neverattempt to lubricate the surface of these
bearings orthearm tracks, as this can cause
premature wear and inaccuracy.
6. WhencarryingyourPowershopresist the temptation
to lift itby gripping the worktable — grip the base
frameinstead. Ifyou lift itbythe worktable you risk
twisting itand therefore reducing the accuracy of
your machine.

10. THE VARIOUS OPERATING ADJUSTMENTS OF BASIC MACHINE
The numbers in bracki
10.1 Arm Rotation
refer to those in the ''Controls" illustrations on page 2
The radial arm rotates to right or left for mitrecuts.
Release the mitreclamphandle(18) andthe mitrelatch
(19). Thenswing thearm(2) right or left tothe required
angle.Thenlock the clamp handle(18).
The calibratedmitrescale (1) is justbelow the elevating
handle and indicates the angle ofthearm relative tothe
'0' straightcross-cutposition.
The mitrelatch (15) is onlyused to locate thearminthe
0°and45° positions but adopt the habit of using the mitre
clamphandlealso to secure thearmin this, as well asany
other, position.
10.2 Blade Height
The RadialArm, and hencealso theSaw blade, canbe
raised or lowered by turning the elevating handle (6)
top ofthe column.Eachcompleterotation ofthe handle
moves the blade upor down by about3mm.
10.3Yoke Assembly
Rotation
Changingfromcross-cut totherip positiontakes only
seconds.
Release therip slide bar(4)andthe yokeclamp(10) and
then swing the yoke to right or left. The yokelocks
automatically atthe four 90° positions, but remember to
alwayssecure the yokeclampalso to maximiseaccuracy.
10.4 Blade Tilting Turn the elevatinghandle to raise the sawblade well above
the table.Releasebevelclamp(12) and bevel latch (1'

elevating handle. Lock the mitre latch in position and
tighten thearm clamphandle.
Turn the elevatinghandle to lower the blade into
position behind the fence inits correct position for
the thickness ofthe materialbeing cut (SeeFig. 25)
To cut rightthrough the material tobe sawn itis
necessary tocuta shallowgroove or kerf also inthe
tabletop. If such a groove isnot already there, switch
on the motorbefore the bladeactually touches the
tablesurface so that it will cut into the table slightly
whenloweringcontinues.Switch offthe motor.
Place material on worktable and hold firmly against
the fence,keepingyourthumb and fingers well away
from the path the sawbladewilltake.
Switch on motor and draw the sawblade through the
fence and across the material to make the cut. You
will findthat youdonot need to pull the motor
assemblyforward - rather you willneed to limit the
speed of travel inthecut otherwise the blade will
tend to jam.
After completing the cut,switch offand carefully
return the sawblade toits restposition behind the
fence.

The fenceshould be placed in position depending on
the thickness ofthe material(SeeFig.25).
Proceed to make thecutinthe same wayasfor
crosscutting.Rememberthat you willneed tocut
slightly into the tablesurface tocut rightthrough your
material and each mitreangle cut willrequire a
different slot cutinthe fence.
Whencutting a left-handmitre(Fig.29), you will
probablyrequire a different fencepositionfromthat

required, the bevel clamp onitsown willhold the
motorrigidly in position.
Place the fence in positiondepending onthe
thickness of material(SeeFig.25).
Then,with the sawbladestillbehind the fence,
carefully lower the blade with the motorrunninguntil
it justcutsinto the tablesurface. The blade can then
be drawnthrough the fence and into the material.
Set thearmasfor crosscut.
Pull the yokeassembly outtotheendofthe arm.
Release therip locatingslide barandthe yoke

(ii) Release thearm clamphandle andthe mitre latch.
(iii)Swing thearm into the requiredmitrepositionthen
relock thearm clamphandle.
(iv) • Draw thesaw across the material asfor mitrecuts.
Note: Youmay find it advisable to clamp the material tothe
fence to hold it firmlywhilecutting.
By tilting the motorwith the blade rotating inthe work, you
can produce manyshapes not possible with conventional
sawingsystems. In Fig. 36,a shallowconcave profile is
beingcut.Havingtilted the blade and rotated the motor
yoke beneath the arm, the material isfed through asfor
ripping. By changing the anglecombinations, an infinite
variety of widths and pitches of channel canbe made.
The optional PowershopHandbookgivesfurther
examples ofhow thisfeature of your machine canbe
utilised.
By releasing the bevelclamp and disengaging the bevel
latch with an appropriately shapedpiece of wood, the
rotating blade can then be tilted through anarctocuta
shallowhollow inthe surface ofa piece of wood clamped
to the table. The blade is thenreturned tothe0° upright
position andthe elevatinghandlewounddown half a turn
beforetilting the rotatingbladeagain and repeatingthis
procedure until the requireddepth has beenreached.

11.9 Circle Cutting
(Fig. 38)
Although a circular sawis normallythought ofas only able
to makestraight cuts, cutting perfectcircles is alsoquite
straightforward on yourradial armsaw usingonly the
standard circular saw blade.
Cramp a falsetable tothe mainone, or substitute a strip
as thick asthe table itself in place ofthe fence. Usea
woodscrew asa pinand screwthispart way into the
chosen aid, and then sawthe head off.Make a hole inthe
underside ofthe wood,from which the circle istobe
formed, and then fittothe pin. Lower the bladejustclear
of the wood, and lock the carriage ata tangent tothe
proposed circular cut. Hold the woodfirmly and lower the
armby half a turn.Thenusingbothhandsrotate the wood
onthepinina clockwisedirectionagainst the blade. After
each revolution lower thearmby half a turn until allthe
waste iscut away, andthe circularpiece is formed.

12. OPERATION OFTHE MACHINEWITHOPTIONALATTACHMENTS AND
ACCESSORIES
Even inits standardformwith the basicgeneralpurpose
sawblade, the Powershop is alreadymoreversatilethan
any othertype of sawingsystem.
The range of optionalattachments,however, adda further
dimension to yourwoodworkingpotential.They will turn
your Powershopinto a completeworkshop.
You will find the optional TCTsaw bladesprove
advantageous,particularlywhencuttinghardwoods and
man-made materials. TCT bladesrequirelessfrequent
'sharpening and have a muchlonger life thanordinarysteel
blades.
Note: Never use bladeslargerthan250mmdiameter —
an imperial 10" blade measures254mmdiameter
andis therefore too large.
Before mounting or changing any attachments or
accessories, disconnectyourPowershopfrom the
mains powersupply.
12.1 Shaping/
Moulding
Adding that professional finish to yourworkwith a clean
decorative edge is quick and easywith the optional
DeWaltShapingHead attachment (Fig. 39). Itcan also be
used for cutting roundgrooves andfor drawer, and tongue
and groovejoints. The range of cutterprofilesavailable is
illustrated inthe list atthe back of thisbooklet.
The DeWaltShaping/MouldingHead is mounted onthe
motorarbor as follows:
(i) Remove thesaw bladeguard,arbor nut, blade
flanges andsaw blade.
(ii)Mount the specialbackflange(s)(suppliedwith the
ShapingHead)onto the motorarbor.
(iii) Nowputthe ShapingHead onthe motor shaft with
the recessedcentrefacingoutwards and thenlock it
intopositionwith the specialclamping nut, using the
special box spanner(Fig.40).
(iv) Fitthe requiredpair of shapingknives inthe Head or
Block carefullysettingthem so theybothprotrude to
the sameextentbeyond the outsideedge ofthe
Block itself.
Fig. 39
Fig. 40

Fig. 42
(v) Now, tilt the motor toits90° position onthe bevel
scale so that the Shaping Head is horizontal.
(vi) Beforeoperating the machine you should now mount
the specialShapingHead guard and adjust its
positiondepending onthe depth of knife profile you
intend touse (Fig.39).
Position the yokeassembly onthearmso thatonly
the amount of knifeprofilerequired extends in front of
the fence. The height ofthe Shaping Head above the
tablewilldepend onthe height of your material and
the position the moulding isto trace onit.Ifthe
ShapingHeadneeds tobeina position otherwise
obstructed bythe fence, you have the following two
options:
EITHER A.Cut away a section ofthe existing fence
to providesufficientspace forthe block
and guard to protrudethroughit*.
OR B. Position two pieces of timber (ofthe same
thickness asthe fenceprovided) inthe
fenceposition, oneon eitherside ofthe
moulding block.
"Note:- Ifyou chooseoption A,itis recommendedthat
you replace the modifiedfencewith a complete
new fence for normalsawingoperations.
(viii) Havinglocked the yokeassemblyintoposition onthe
arm with therip lock and positioned the guard so that
it justclears the material,feed the materialfirmly and
evenly along the fencefrom the rightinto the shaper
cutters.Maintainpositivepressure.
IMPORTANT:Use a piece of wastewood asa
pusher(Fig. 41)to makesureyour
handkeeps a safedistancefrom the
knives.
(viii) An infinitevariety of profiles canbecut using the
ShapingHead by varying the height ofthe cutter
presented tothe wood(Fig.42).
NOTE:Figs. 39/40 feature the DeWalt Premium
QualityShaping Head which is designed for
the moreintense,larger profile
shaping/rebatingapplications. There is also
available, however, a general-duty shaping
head(Fig.43),which is perfectlysatisfactory
for slow-feed, fine-finish applications andhas
a similarlywiderange of compatible cutters.

12.2Rebating
Fig. 45
(i) With the straight-edgedknives mounted, the
Shaping/Moulding Head can also be used for narrow
rebating, inthe same wayas described above.
(ii) If widerrebates are required,then a DadoHead
should be fitted(seeseparateinstructions) butthe
guardusedshould be thatintended forthe Shaping
Head. The operation, using the Dado Head in this
way, isthe same as with the ShapingHead(Fig.44).
Note theuseof home-madewoodensprings to help
in ensuring the timber is heldfirmlyagainst the fence
whilecuttingprogresses(seeFig. 41).
(iii) Again the motor canbe tilted for bevelled rebate
cutting.
(iv) Ifthe rebating is necessary fora mortice and tenon
joint, then the DadoHead canbe used inthe normal
cross-cutpositionwithrepeatedpasses ofthe Head
across the materialuntil the required width of rebate
has beenobtained(Fig.45).
