Attaching a Coupling or a Chuck to the Mixer Unit
When attaching a chuck or coupling, always align and tighten
the set screws, (J) see Fig. 3, only onto the flat surface of the
motor shaft (shaded area) see Fig. 2.
Failure to do so could cause damage to the shaft and prevent
the coupling or chuck from being removed.

SHAFT-COUPLING-PROPELLER
ASSEMBLY
As with the motor shaft, always
align and tighten the set screws,
(K) see Fig. 3, only onto the flat
surface of the propeller shaft.
When removing the propeller,
grasp shaft tightly, preferably in a
vise, and gently tap the propeller
counterclockwise at the base of
the blade (L). The propeller is
threaded onto the shaft.

SAFEFTY INSTRUCTIONS
Readtheoperatinginstructionsinfullbeforestarting
upandfollowthesafetyinstructions.
•Keeptheoperatinginstructionsinaplacewhereitcanbe
accessedbyeveryone.
•Ensurethatonlytrainedstaffworkwiththeinstrument.
•Followthesafetyinstructions,guidelines,occupational
healthandsafetyandaccidentpreventionregulations.
•Becausetheoptionsforcombiningproducts,tools,stirring
vessel,experimentandmediumarenearlyendless,
usersafetycannotbeensuredsimplywithdesignrequirements
onthepartoftheproduct.Forthisreason,itmay
becomenecessaryforuserstotakeotherprecautionary
safetymeasures.Forexample,glassapparatusorother
stirringvesselsthataresensitivetomechanicalstresscan
bedamagedorshatteredbyanimbalance,increasingthe
speedtooquicklyortoolittledistancebetweenthestirring
elementandthestirringvessel.Userscansufferserious
injuryfromglassbreakageorfromthefreelyrotating
stirringelement.
•Uncontrolledreactionscanbetriggeredbymixingthe
heatedmaterialinsufficientlyorbytheenergygenerated
byselectingaspeedthatistoohigh.Incaseofthese
andotherincreasedoperationalhazards,usersmusttake
additionalappropriatesafetyprecautions(e.g.shatter
protection).Inanycase,whenusingcriticalorhazardous
materialsinyourprocesses,Arrow
 recommendsusing
additionalappropriatemeasurestoensuresafetyinthe
experiment.Forexample,userscanimplementmeasures
thatinhibitfireorexplosionsorcomprehensivemonitoring
equipment.Furthermore,usersmustmakesurethat
theOFFswitchoftheArrow
 productcanbeaccessed
immediately,directlyandwithoutriskatanytime,and
aboveall,incaseoffault.

Ifmainsswitchcannotensure
thisaccessatalltimes,anadditionalEMERGENCYSTOPswitch
thatcanbeeasilyaccessedmustbeinstalledintheworkarea.

•Onlyprocessmediathatwillnotreactdangerouslytothe
extraenergyproducedthroughprocessing.Thisalsoapplies
toanyextraenergyproducedinotherways,e.g.
throughlightirradiation.
•Donotoperatetheinstrumentinexplosiveatmospheres,
withhazardoussubstancesorunderwater.
•Theinstrumentisnotsuitableformanualoperation.
•Thehightorquedevelopedbythe1750digitalrequires
particularcareinthechoiceofstand,crosssleeve
andanti‐rotationelementfortheagitatingvessel.
•Setupthestandinaspaciousareaonaneven,stable,
clean,non‐slip,dryandfireproofsurface.
•Youmustensurethatthestirringelementissecurely
clampedinthecouplingorchuck.

Whenusingachuck,makesuretoremovethe
chuckkeyfromthechuckbeforeturningonthedevice.

•Usestirringshaftprotectiveequipment!
•Theagitatedvesselsusedforstirringhavetobesecured.
Consideronagoodstabilityoftheentirestructure.
•Protecttheinstrumentandaccessoriesfrombumping
andimpacting.
•Checktheinstrumentandaccessoriesbeforehandfor
damageeachtimeyouusethem.Donotusedamaged
components.
•AlwaysswitchthemainsswitchintheOFFpositionor
disconnectthepowerbeforechangingstirringelement
andfittingallowedaccessories.
•Theinstrumentcanonlybedisconnectedfromtheelectrical
outletsupplybypullingontheplug.Donotpullonthecordto
disconnectpower.
•Thesocketfortheelectriccordmustbeeasilyaccessible.
•Theelectricaloutletmustbegrounded(protectiveground
contact).
•Thevoltagestatedonthelabel(seeFig.1‐E)mustcorrespond
totheelectricaloutlet’svoltage.
•Pleaseobservethepermittedspeedforthestirringelement.
Neversetathigherspeed.
•Makecertainthattheunitissetatthelowestspeedbefore
turningthepowerswitchon;otherwise,theunitwill
immediatelybeginrunning.Graduallyincreasetorequired
speed.
•Payattentionwhensettingthespeedtoanyimbalanceof
thestirrertoolsandpossiblesprayingofthemediumto
bestirred.

Neveroperatetheinstrumentwiththestirrer
toolsrotatingfreely.Ensurethatpartsofthebody,hair,jewelry
oritemsofclothingcannotbetrappedbytherotatingparts.

Theoperationofafreerotatingshaftendis
dangerous,therefore,forsafetyreasons,onlyinsertthestirring
toolintotheupperedgeofstirringvesselwiththemotoroff.
Whenfinished,turnthemotoroffbeforeliftingthestirringtool
outofthevessel.
NOTE:
ArrowMixingProductsoffersrepairandmaintenanceonall
equipment.AnRMAmustberequestedandincludedwithall
returns.Arrowwillinspecttheunitandcallyouwithaquote
beforeanyworkisdone.


Wearyourpersonalprotective
equipmentinaccordancewith
thehazardcategoryofthemedium
tobeprocessed.Otherwisethereisariskof:

‐splashingofliquids
‐projectileparts
‐bodyparts,hair,clothingandjewelrygettingcaught.

Bewareoftheriskof:

‐flammablematerials
‐glassbreakageasaresultofmechanicalshakingpower.

Reducethespeedif:

‐themediumsplashesoutofthevesselbecausethe
speedistoohigh
‐theinstrumentisnotrunningsmoothly
‐theinstrumentbeginstomovearoundbecauseofdynamic
forces
‐anerroroccurs.

Donottouchrotatingpartsduringoperation!

•Theremaybeelectrostaticactivitybetweenthemedium
andtheoutputshaftwhichcouldcauseadirectdanger.
•Itisimportanttonotethatthesurfacesofthemotorand
certainpartsofthebearingmaygetveryhotduringoperation.
•Avoidknockingandimpactingonthelowerendofthe
shaftandthechuckgearteeth.Evenminor,invisibledamage
canleadtoimbalanceandunevenshaftaction.
•Ensurethatthestanddoesnotstarttomove.
•Imbalanceoftheoutputshaft,thechuckandinparticular
thestirringtoolscanleadtouncontrolledresonant
vibrationalbehavioroftheinstrumentandthewhole
assembly.Glassapparatusandstirrercontainerscanbe
damagedorshatteredbythis.Itcancauseinjurytothe
operator,alsocandamagetherotatingstirringtool.In
thiscase,exchangethestirringtoolforonewithoutimbalance
orremedythecauseoftheimbalance.Ifthereis
stillimbalance,returnittothedealerorthemanufacturer
alongwithadescriptionofthefault.
•Iftheinstrumentisoperatedaboveitscapabilities,thereset
buttonwilltrip.
•Themachinemustonlybeopenedbytrainedspecialists,
evenduringrepair.Theinstrumentmustbeunplugged
fromthepowersupplybeforeopening.Livepartsinside
theinstrumentmaystillbeliveforsometimeafterunplugging
fromthepowersupply.

Coveringorpartsthatarecapableofbeing
removedfromtheunitwithoutaccessoryequipmenthavetobe
reattachedtotheunitforsafeoperationinordertoprevent,for
example,theingressoffluids,foreignmatter,etc.

‐R&DandProductionFacilities
Thesafetyoftheusercannotbeguaranteed:
‐Iftheinstrumentisoperatedwithaccessoriesthatarenot
suppliedorrecommendedbythemanufacturer
‐Iftheinstrumentisoperatedimproperlyorcontrarytothe
manufacturer’sspecifications
‐Iftheinstrumentortheprintedcircuitboardaremodified
