Generalsafetyinformation:



Beforeusingthemachine,theoperatingmanual
andsafetyinformationmusthavebeenreadand
understoodintheirentirety.Theinstructions
containedthereinmustbefollowed.
Theseoperatinginstructionsarebasedonthe
relevantpartsoftheEuropeanMachinery
Directive(98/37/EC)andtheCENTC255
regulations“Hand‐held,non‐electricpowertools
–Safety”.

Theseinstructionscovertheoperationandhan‐
dlingofthemachine,includingtools,accessories
andmachinemaintenance.

Failuretocomplywiththeseestablishedsafety
recommendationscancauseserioushazards.
Themachineoperatormusthaveproperlyun‐
derstoodthefollowingsafetyadviceandmust
haveaccesstotheseinstructionsatalltimes.

Topreventimproperhandlingofthemachine
andtopreventaccidents,theoperatormust
complywiththesafetyprecautionssetoutbe‐
low.
Installation:

Complywiththespecificationsregarding
compressedairquality,whicharecontainedin
theoperatinginstructionssuppliedwiththe
machine.




Onlyusetherecommendedlubricants.

Checkpneumatictubingandairpressure.When
themachineisrunning,theairpressureatthetool
inletshouldnotexceed7bar(=700kPa=100psi),
oralowermaximumoperatingairpressureif
specified.

Avoidhazardsassociatedwithvibrating
pneumatictubing.Checktheconditionofthe
tubing,tubeconnectorsandtubeclamps
regularly.
Makesurethattheexhaustairventispositioned
sothatdustorairdrawnfromtheworkpieceisnot
directedtowardtheoperatororanyotherperson.
Asafetyscreenshould,ifpossible,bepositioned
betweentheoperatorandthe
workpiece.
Pneumatically‐drivenpowertoolsaregenerally
notinsulatedinawaythatwouldallowthemto
comeintocontactwithanelectricalpowersource.
Ifanexplosionhazardexists,usesomeother
machiningtechniquethatdoesnotgenerate
sparksinordertoavoidpersonalinjuryor
damagetopropertyfromfire.




Alwaysdisconnecttheairsupplytubefromthe
machinebeforeservicingorcarryingout
maintenanceonthemachine.
Beforeeachuse,alwaysinspectthepneumatic
tubingforsignsofwearordamage.
