6.4Mountingtoworkbench
Thesandershouldbeboltedtoaworkbenchortable
toavoidanytendencytocreeporslideduring
sanding operations. Use appropriate fasteners (not
provided)throughthe4slotsinthemachinebase.
6.5Dustcollection
Dustcollectionismandatoryforasafework
environment and extended abrasive life. The JWDS‐
1020isequippedwitha100mmdustcollectionport.
Securea100mmdustcollectionhose(notprovided)

6.6Installingabrasives
Properattachmentoftheabrasivestriptothedrum
iscriticaltoachievingtopperformancefromyour
drumsander.
An80‐grit,76mmwideabrasivestrip ispre‐installed
onthedrum.
(TIP:Ifyouareusinganafter‐marketabrasive,usea
new JET‐supplied abrasive as a template to quickly
cutanewstrip.


abrasivethroughslitinfastener,asshown.Align
taperededgeofabrasivestripwithleftedgeof
drum.Insertenoughstripsothattherightedge
alignswiththereferencenotch;thiswillensure
the proper length of strip to be secured at the
oppositeendofthedrum.

Figure6‐4
3. Releasefastenerlevertosecureendofstrip.
4. Begin wrapping abrasive around drum. The
tapered edge of strip end should follow as
closelyaspossibletoedgeofdrum.
5. Continue to wrap abrasive in spiral fashion by
rotating drum with one hand and guiding strip
withtheother.SeeFigure6‐5.
Successive windings of strip must not have any
overlap. They should be flush with previous
windingsorwithaslightgapbetween.

necessary,trimtaperedendofabrasivestrip.
7. Releaseinboardtake‐uplevertosecurestrip.
All abrasive strips will stretch over time as they are
used, and may stretch enough to allow the take‐up
lever to reach its lowest position so that it cannot
maintaintensiononthestrip.Ifthisoccurs,follow
theaboveprocedurestoresetthetake‐uplever.

7.0Electricalconnections
Allelectricalconnectionsmustbe
donebyaqualifiedelectricianincompliancewithall
local codes and ordinances. Failure to comply may
resultinseriousinjury.
The JWDS‐1020 Sander is rated at 230‐Volt power
only.Thesandercomeswithaplugdesignedforuse
onacircuitwithagrounded outlet. Before
connectingtopowersource,besureswitchisinoff
position.
Itisrecommendedthatthesanderbeconnectedtoa
dedicated16ampcircuitwithcircuitbreakerorfuse.
Ifconnectedtoacircuitprotectedbyfuses,usetime
delayfusemarked“D”.Localcodestakeprecedence
overrecommendations.

8.0Adjustments
8.1DrumHeightControl
Drum height and depth of cut are controlled by the
height adjustment handle (see Figure 6‐1). Rotating
handle clockwise lowers drum, counter clockwise
raises it. One revolution of handle will move drum
approximately1.6mm(or1/4turn=approx.0.4mm),
asshownonthelabelbelowhandle.
8.2Depthscale
The depth scale indicates distance between bottom
of sanding drum and top of conveyor belt.
Adjustmentisperformedby“zeroing”thescale.
1. Unplugsanderfrompowersource.
2. Withanabrasivestripondrum,lowerdrumto
where it touches top of conveyor belt. Note:
Makesuredrumcontactsbelt,notjustthefeed
rollers.
3. At this drum position, the (top edge of) depth
scale pointer should align with zero mark on
scale. If it does not, loosen screw (Figure 8‐1)
andshiftpointertoalignwithzero.
4. Retightenscrew.
Note:Dependingondesiredaccuracy,youmayneed
to repeat this process when installing different
abrasivegrits.

8.3Conveyorbelttensionandtracking
Conveyorbelttension adjustmentmaybenecessary
during the break‐in period to compensate for belt
stretching,andalsoafterlong‐termuse.
8.3.1Belttensionadjustment
NOTE:Insufficientbelttensionwillcauseslippageof
conveyor belt on drive roller during sanding
operation.Theconveyorbeltistoolooseifitcanbe
stopped by hand pressure applied directly to top of
moving conveyor belt. Excessive belt tension can
result in bent rollers, bent brackets, and/or
prematurewearingofbushingsorconveyorbelt.
Toadjustconveyorbelttension:
1. Slightlyloosenfourscrews(A,Figure8‐2)on
infeed side of conveyor, with 4mm hex wrench
(twoscrewsoneachside).
2. Turntake‐upscrew(B,Figure8‐2)with5mmhex
wrench. Do this on both sidesofconveyorto
obtain approximately equal tension on both
sidesofsandingbeltwhentaut.
3. Tightenfourscrews(A,Figure8‐2).
4. Check conveyor belt tracking before operating
machine.Proceedtosect.8.3.2.

8.3.2Trackingadjustment
Abelttrackscorrectlywhenitmovescentrallyonthe
conveyor rollers without drifting to either side.
Trackingadjustmentsaremadewhileconveyorbeltis
running.
1. Make sure proper belt tension has been
achieved(sect.8.3.1).
2. Turn on conveyor and set to maximum speed.
Watchfortendencyofconveyorbelttodriftto
onesideofconveyor.
3. Ifconveyordrifts,slightlyloosentwoscrews(A,
Figure8‐2)and turntake‐upscrew (B,Figure8‐
2)ononesideofconveyorasneeded.
Note: Adjust take‐up screw only 1/4‐turn at a
time.Allowtimeforbelttoreacttoadjustments
beforeproceedingfurther.
4. Whenadjustmentissatisfactory,tightentwo
screws(A,Figure8‐2).
Avoidover‐adjusting,asthismayaffectbelttension.
Iftensionisaffected,ifmaybecomenecessarytouse
both take‐up screws to accomplish tensioning and
tracking.
8.4Inspectingdrumalignment
Thesandingdrummustbeparalleltoconveyortable
for proper machine operation. The sanding drum
comes pre‐aligned from the manufacturer. If a
problem with drum alignment should occur, follow
theinstructionsbelow.
First, inspect the alignment with a gauge of some
kind. The following procedure uses a steel straight‐
edgeasagauge.
1. Unplugsanderfrompowersource.
2. Openhoodandremoveabrasivestripfrom
drum.
3. Positiongauge(F,Figure8‐3)betweendrumand
conveyortableatoutboardsideofdrum.

Figure8‐3:drumalignment
4. Withhoodopen,lowersandingdrumwhile
slowlyrotatingdrumbyhand,untildrumlightly
contacts gauge. NOTE: Make sure gauge is
contacted by the drum, not just the tension
rollers.Makeanoteofthemeasurementonthe
sander’sdepthscale.
5. Removegaugeandplaceunderdrumatinboard
side.
6. Ifdrumdoesnotcontactgaugeequallyonboth
endsofdrum,alignmentisneeded.
8.4.1Performingdrumalignment
Toalignconveyortablewithdrum:
1. Loosenbothtablelockingscrews(C,Figure 8‐3)
with5mmhexwrench.
Loosen both table locking
screwsbeforeadjustingdrumalignment.
Toe.g.raiseoutboard end of table, loosen lock
nut (E, Figure 8‐3) and rotate knurled nut (D,
Figure8‐3)clockwise(+).
2. Verifysettingusingthegauge.Makefurther
adjustmentsusingknurlednutasneeded.
3. Retightentablelockscrews(C).
8.4.2Fine‐tuningdrumalignment
Note:Thisisanoperationaltestforsandingboards
wider than the drum. Perform this procedure only
after you have become familiar with sander
operation.
Whensandingboardswiderthanthedrum,table
alignment is critical and table must be adjusted
exactly level to slightly lower on the outboard end.
This will prevent any ridges from developing in the
stock.Alwayscheckthisonapieceofscrapwood,as
follows,beforesandingtheworkpiece.
1. Run a piece of scrap wood approximately
150mmwideby400mmlongthroughthesander
sidewayssothatendofboardextendspast
outboard side of drum, so that approximately
50%ofthesurfaceismachined.
2. Without changing drum height, rotate board
180°andsandthesameside.
