VERTICALGUIDEROLLERS
1. Theserollersaremountedneartheendofthe
indextableandprovidestwolaterallyvertical
rollers.
2. Whentheverticalrollerisnotneeded,itcanbe
swiveledinthedownposition.
HYDRAULICSYSTEM
1. The hydraulic and band drive systems operate
independently.Thisallowstheoperatortoperform
following tasks while the banddrive motor is not
running: (a) change saw bands; (b)raise or lower
the saw head; (c) clamp or unclamp vises; (d)
positionstockmanually.
2. Themachine’shydraulicreservoircapacitydepends
onthemachinemodel(seemachinespecifications
chart). Refer to the lubrication section of this
manualforrecommendedoils.
COOLANTSYSTEM
Coolantselection
1. The main cause of tooth failure during band
machining is excessive heat built‐up. Using the
propercuttingfluidreducestheheatgenerated
during operation. It also helps the machine take
fulladvantageofitshigh‐speedsteelsawbands.
Coolantapplication
Literaturedescribingtheseandother coolant
types are available from your DoALL sales
representative.

1. Coolantisappliedasfollowsduringsawing:
 Tothesawbandandcuttingareathroughthe
sawguideinserts.Flowisregulatedbyavalve
oneachsawguidearm.
 To the band brush cleaning area through a
flushingnozzle.Flowiscontrolledbyavalve.
 Tothecuttingareathroughaflushingnozzle.
Flowiscontrolledbyavalve.
 Anadditionalflexibleflushingnozzlecanapply
fluidwhereneeded.Controlledbyavalve.

2. Coolantflowisstartedby:(a)pushingthehydraulic
startbutton;(b)turningthecoolantselectorto“I”
or“AUTO”;(c)turallthecoolantvalvesonuntil
fluidscompletelyshroudsthesawband.
3. Checkthecoolantreservoirlevelifflowisstopped
orreduced.Reservoircapacitydependsonmachine
model.Acoolantlevelsightgaugeislocatedatthe
frontrightbottomofthemachinebase.

CHIPREMOVAL
DONOTshovelorrakechipswhilethe
sawbandisrunning.

1. Metalchipsshouldberemovedfromtheworkarea
assoonaspossible.Theycanbewashedorscraped
intothechipconveyortrough.
Bandbrush
1. Acovered,banddrivemotordrivenbandbrushis
located near the right saw guide arm. During
machine operation, the brush bristles should be
positionedsothatthetipscleanchipsfromthe
teethtips,butshouldnotcontactthebottomofthe
gullets.DONOTallowmetalchipstoaccumulateon
thebrush.
2. Asthebristleswear,movethebrushclosertothe
blade.Todoso:(a)opentherightwheelcover;(b)
loosentheclampinghandle;(c)positionthebrush
forcorrectbladecleaning;(d)tightentheclamp
handleandclosethewheeldoor.
Flushinghose
1. Metalchipsandotherdebrismayaccumulateover
timearoundsuchareasas:sawguides,bothband
wheels,vise,slide,brushhousing,headliftcylinder,
feedanddischargeareas,etc.
2. The operator should check often for these
collectionswhichcanaffectmachineperformance.
Theyshouldberemovedwiththeflushinghoseas
soonaspossible.
TheDoALLCompanyrecommendsusingthe
flushinghosetoremovechipsatleasttwice
per eight‐hour shift, and more often with
heavieruse.
