BLADE SELECTION
An 8-toothper inch,general-use bladeis furnishedwith thismetal cuttingband saw.Additional bladesin 4-,6-,
8- and10-tooth sizesare available.The choiceof theblade pitchis governedby thethickness ofthe workto
be cut;the thinnerthe workpiece, themore teethadvised.Aminimum ofthree teethshould engagethe work
piece atall timesfor propercutting. Ifthe teethof theblade areso farapart thatthey straddlethe work,severe
damage tothe workpiece andto theblade canresult.
CHANGING BLADE
Ensure poweris disconnectedfrom saw. Raisesaw headto verticalposition andopen theblade guards.
Loosen tensionscrew knobsufficiently toallow thesaw bladeto slipoff thewheels. Installthe newblade with
teeth slantingtoward themotor asfollows:
1.Placethe bladein betweeneach ofthe guidebearings.
2.Slipthe bladearound themotor pulley(bottom) withthe lefthand andhold inposition.
3.Holdthe bladetaut againstthe motorpulley bypulling theblade upwardwith theright hand,which isplaced
at thetop ofthe blade.
4.Removeleft handfrom bottompulley andplace itat thetop sideof theblade tocontinue theapplication on
the upwardpull onthe blade.
5.Removeright handfrom bladeand adjustthe positionof thetop pulleyto permitleft handto slipthe blade
around thepulley,using thethumb, indexand littlefinger asguides.
6.Adjustthe bladetension knobclockwise untilit isjust rightenough sono bladeslippage occurs.Do not
tighten excessively.
7.Replacethe bladeguards.
8.Place2-3 dropsof oilon theblade.
USAGE OFTHE QUICKVISE

you toinstantly positionthe movablevise jaw(B). Simplyturn hand
wheel (A)counterclockwise 1/2turn andmove thevise jaw(B) to
the desiredposition. Thentighten thevise jaw(B) againstthe work
piece byturning hand-wheelclockwise.
QUICK VISEADJUSTMENT FORANGLE CUT
1.LoosentheA, C,E screws.
2.Adjustrear vise(B) tothe threadedhole position.
3.Setthe scaleto thedesired angle.
4.Adjustthe frontvise (D)to parallelthe rearvise (B).
5.TightentheA, C,E screws.
BLADE GUIDEBEARING ADJUSTMENT
This isthe mostimportant adjustmenton yoursaw.It isimpossible toget satisfactorywork fromyour sawif the
blade guidesare notproperly adjusted.The bladeguide bearingfor yourband saware adjustedand power
tested withseveral testcuts beforeleaving thefactory toinsure theproper setting.The needfor adjustment
should rarelyoccur ifthe sawis usedproperly.If theguides becomeout ofadjustment, itis extremely
important toreadjust immediately. Ifproper adjustmentis notmaintained, theblade willnot cutstraight andif
the situationis notcorrected, itwill causeblade damage.
Because guideadjustment isa criticalfactor inthe performanceof yoursaw,it isalways bestto trya new
blade tosee ifthis willcorrect poorcutting beforebeginning toadjust thebearings. Ifa bladebecomes dullon
one sidesooner thanthe other, forexample, itwill notcut straight.Asimple bladechange shouldcorrect this
problem themore difficultguide adjustmentwill not.
If anew bladedoes notcorrect theproblem, checkthe bladeguides forproper spacing.
There shouldbe 0.001"clearance betweenthe 0.025"thickness bladeand guidebearing. To obtainthis
clearance, adjustas follows:
1.Theinner guidebearing isfixed andcannot beadjusted.
2.Theouter guidebearing ismounted toan eccentricbolt andcan beadjusted.
3.Loosenthe nutwhile holdingthe boltwith awrench.
4.Positionthe eccentricby turningthe boltto thedesired positionof clearance.
5.Tightenthe nut.
6.Adjustthe secondblade guidebearing inthe samemanner.
7.Theback edgeof theblade shouldjust touchthe lipof theblade guidebearing.

BLADE TRACKADJUSTMENT
1.Openthe bladeguard.
2.Removethe bladeguide assemblies(top andbottom)
3.Loosenthe hexhead screwin thetilting mechanismto apoint whereit isloose butsnug.
4.Withthe machinerunning, adjustboth theset screwand bladetension knobsimultaneously tokeep
constant tensionon theblade. Theset screwand bladetension knobare alwaysturned inopposite
directions, whenone isturned clockwisethe otheris turnedcounterclockwise. Theblade istracking properly
when theback sidejust touchesthe shoulderof pulleyor aslight gapappears nearthe centerline ofthe
pulley.Care shouldbe takennot toover tightenthe sawblade sincethis willgive afalse adjustmentand limit
life ofthe blade.
5.Tightenthe hexhead screwin tiltingmechanism. IMPORTANT: Sometimesin tryingto makethis critical
adjustment itis possibleto causethe basicsetting tobe misaligned.Should thisoccur,proceeds asfollows:
a.Loosenthe setscrew andback itout asfar asit cango andstill remainin thethreaded hold.
b.Turnthe hexhead screwclockwise untilit stop(do nottighten).
c.Turnthe setscrew clockwiseuntil itbottoms, thencontinue forhalf aturn andcheck thetracking byturning
on themachine.
d.Iffurther adjustmentis required,go backto step4.
6.Turnoff powerto themachine.
7.Replacethe bladeguide assemblies it maybe necessaryto loosenthe bladetension alightly.
8.Adjustthe verticalposition ofblade guidebearing assembliesso thatthe backside ofthe bladejust touches
the ballbearings.
