1.1.GeneralSafetyTips
Beforeoperating tool makesureto carefullyreadand
observethisoperating instruction.
Generally,theoperator ofthe equipmentand/ormachineryisresponsible for
the equipment’sperfect condition and operation,while observing all necessary
safetyregulations.The equipmentand/or machineryhasbeen constructed in
accordancewiththe newestlevel oftechnologywhile recognizingall
necessarysafety-related requirements.Nevertheless,while operating the
equipmentand/or machinerythereisariskofbodilyharmtothe operator as
well as damagetoequipmentand/or machineryand other property.
Operatethe equipment and/ormachineryonlyif equipment/machinery
· Isused forthe task it was designed for
· is inperfectworkingcondition andsafetouse.
It isimportanttoobservethe technical dataofthe equipment, especiallyin
regardstotheenvironmental temperatures. The designated area ofuseforthis
equipmentisclearlydescribed in chapter Designated EquipmentUse and
thoserequirementshavetobe observed aswell.Prerequisiteforthe safe
conduct andthe uninterrupted operationofthe equipment, isthe knowledge of
the basicsafetytipsandthesafetyregulations.Additionally,all current
regulationsforasafeoperational area,for accident-prevention guidelinesof
electrical and mechanical installations, aswell asnoisesuppression demands
mustbe observed.Duringanymaintenanceorrepair work, acleanwork

1.2.SafetyTipsfor Grinders
·
Useonlyapproved grinding inserts withacorrectshaftdiameter.
· Makesurethe ratedspeed oftheinsert ishigherthan thespeed
ofthegrindingresp. millingmachine.
· Never useagrindingresp.millingmachine thatis notin good
working orderoronewithdefectiveparts.
· The grindinginserts (wheels/disks)mustbehandledandstoredwithcare
and inaccordancewithmanufacturers instructions.
· Checkthe grindinginserts(wheels/disks)fordamagespriortothe usein
grinding resp.millingmachines. Never usedamagedgrinding inserts
(wheels/disks).Onlyusethegrindinginserts(wheels/disks)inaccordance
withthe manufacturers’instructions.
· Incaseofapower interruption,themachinemustbe disconnected from
the air supply.
· Whenconnecting/disconnectingthe grinding resp. milling machineto/from
the air supply-pleasepaycareful attention NOTtoactuatethestartlever
while doing so.
· Disconnect machinefromairsupplyprior tochanginggrinding inserts.
· Never removeprotectivedevicesfrommachineswherefitted and ensure
theyare ingoodconditionandproperlyadjustedbeforestartingthe
machine.
· Guardswhereprovided shouldbe adjustedtodeflectsparksanddebris
awayfromthe operator.
· Strongvibrationsmayoccurbecauseof looseordamagedgrinding
inserts.
· Donotusecut-off wheels (when usingmachineswithacollet).
· Donotexceedthemaximumallowableoperatingspeed. Checkthe
maximumoperatingspeed regularly.
· Checkthe grindinginserts(wheels/disks)forcorrectandtightclamping,
prior tostart-upofoperation.Testthegrinding resp.millingmachine
without loadin asafepositionandenvironmentforatrial period ofsome
30 sec.When feeling considerablevibrations orinanyother caseof
irregularbehaviour or operationswitchoffthe machine immediately.
Analyzeand eliminateall causes of irregular behaviourand vibration prior
tonewstart-up.
· Whenworkingwithspecificmaterials,dustandabrasionas well assteam
outs canbe createdwhichcouldresult inanexplosiveendangered
environment.
· Makesuretosufficientlyfastenthe work piece(s)priortogrinding/milling.
· Donotusethe machine closetoinflammable liquidsorgas.

·
Doprovide devicesforcleaningthe airatthe workingplace, incase
explosivedust,steamor aerosolsdangeroustoyour healthmayoccur.
· Afterturning-offthegrindingresp. milling machine, the tool will continueto
rotate(inertia).Layasidethegrinding resp.millingmachinein asafeway
and position.Donot applypressure toitssurface.
· Always wear eyeprotection(EN166 Grade B)andhearing
protection(EN352).Itis alsorecommended towear gloves
(EN388Category2) andsafetyclothing.
· Dependenton thematerialstobe processed,personalsafetyequipment
mustbeusedandadustremoval systemshould beinstalled.
· Donotwear wide clothingorjewelry, fortheycan beseizedbymovable
parts. Wearahairnet ifoperatorhaslong hair.
· Dotakedue noteofspecialmarkings,limitationsoranyother explicit
instructionsofuseatthegrindinginsert orthegrindingresp.milling

·
Ensurethatthe correct abrasiveproductisselected.Anunsuitableproduct
can produceexcessivedebris,dust, vibrationandnoise.
· Useonlyabrasiveproducts conformingtothe higheststandardsofsafety.
Theseproducts will beartherelevantENstandardnumberand/or the
inscription „oSa“.
· Donotexceed themaximumallowableairpressure.Apressure regulator
hastobeinstalled, whichregulated theairpressurebeforereachingthe
tool.
· Storeabrasives indry, frost-freeconditions avoiding wide variations in
temperature. Ensuretheyareproperlyprotectedandsupportedtoprevent
damage anddistortion.
· Coated abrasives should bestored at18-22°C, 45-65%relativehumidity.
· Abrasivebeltsshould behungon arodor peg notlessthan50 mm
diameter.
· Never useanabrasiveproductbeyond itsexpirydatewhere marked.
· Donotmodifyneither grinding resp. mil

· Checkthatthe correctmountingdevices are usedandthattheyare
undistorted, cleanand free fromburrs.
· Donotgrindonthe part oftheproductthatis notdesignedforthe
operation.Avoid grinding withtheedgeofabrasivebelts, usethecentreof
the beltif possible.
· Donotleaveabrasivebelts undertension when notinuse.

·
Avoid clogginganduneven wear toensure that the abrasiveproduct is
working efficiently. Dressfrequentlywhere appropriate.
· Beforestart-upoftool makesuretovisuallycheckboththe grinding resp.
milling machineandthegrindinginserts, whethertheyare okayand not
damaged inanywayand whether theyare appropriateforthe workahead.
· Usegrindingresp. milling machineonlywithamaintenanceunit,
consistingofFilter withcondensationreservoir, regulator and oiler(appx.
1-2 dropsprom³). Whenoperatingwithoilfree air,aperformance
reductionofupto20% occursandmaintenancerequirementsincreases!
The pressuremust not drop below6.3bar/90PSI.
· Expert userstrainedbyauthorized, responsibletechnicalpersonnelonly
mustbeallowed towork withthegrinding resp.millingmachine.
· Dowear arespirator(EN149),if usingthe grindingresp. milling machine
for dust-producingjobs.Exposuretodustgeneratedfrom workpiece

· Never applyexcessiveforceor shocktotheabrasiveproductorlet it
overheat.
·
It isespeciallyimportant tokeep inmind,that the allowablespeedof the
installed grindinginsert isreduced, if the distancebetween theend of the
collet and thebottomof the insert (overhang“Lo”)isincreased. Observethe
instructionsgiven bythe manufacturerofthe grindinginsertsresp. carbide

3Installation
·
Blowout airlineandpressure hose,prior toconnection ittothe
equipment.
· The hosesmust befreeofbends andkinks.
· Makesure,thatall air lineshaveasufficientcross-sectionand remove
possiblethrottle areas.
· This DEPRAGGrinder orPolishershould beoperatedwithlubricated
air only(seeparagraph: Maintenanceand Upkeep).Bestresultsare
achieved, when machineislubricatedwith1–2dropsofoil per1m3.
Whenoperatingwithoilfree air,aperformancereductionof upto20%

· ConnectGrinders orPolishersasfollows:
a) for standardoperation connectequipmenttoamaintenanceunit,
consistingofFilter withcondensationreservoir, Regulatorand Oiler.
Whenchoosing amaintenanceunit, observeair consumption ofthe
machine(seeTechnicalData).

4Operation
Prior tocommissioning,be suretoinsertthetool asdeeplyas possibleinto
the colletandfastenitusingthesingle-ended open-jawed wrenchincludedin
the delivery(see Safety Tips).
Attention:
Beforeoperating thetool,checkthatgrinding insertis
securelyfastened.Aloose grinding insertmaycause an
injury.
Use onlyacceptablegrinding inserts. Checkand make
surethattheallowablespeedofthegrinding insertis
higher than thespeedofthegrinder.
Keep the pressurelightduringworking.High speedsatlowpressure are
preferable over lowspeedswithhighpressure.Whenselectingamilling
cuttermould, makesure thattheworkpieceradiusofboreholesorangles is
always larger thanthe millingcutterradius,asthemillingcutterotherwiseget
