4. Functional description
4.1 Description
Thecombinationdeviceshavebeendesignedinsuchawaythatahydraulicallyoperated
pistonactivatesmechanicaljointssymmetricallytoopenorcloseasetoftwooppositeblade
arms,thusenablingobjectstobecut.
Foralldevices,themovementisactivatedbymeansofavalveintheformofastargrip.
Alldevicesguaranteethedeadman'sswitchandthefullload-supportingfunctionwhenthe
stargripisreleased.
HURSTeDRAULICdevicesdonotneedtobeconnectedtoanexternalhydraulicsource
(e.g.amotorpump).Generationoftherequiredhydraulicpressuretakesplacewithinthe
bodyofthedevice.
Eitherabatteryoranexternalpowersupplymustbeconnectedasanenergysource.
Youcanchoosewhichenergysourceyouwishtouse.Boththeaccumulatorbatteryand
themainspowerunitcanbeinsertedintotheopeningprovidedinthebodyofthetool.
Theyarethenautomaticallylockedintoposition.
YoucanextendtheoperatingtimeofyoureDRAULICdevicebyusingseveralbatteries.
Thebatteriescanberechargedafteruse,usingasuitableexternalcharger.
Ifyouaremakinguseofanexternalpowersupply,thedevicecanbeusedforanalmost
unlimitedtime.Thistimeisonlylimitedbytheexternalenergysourceandtheoverheating
switchofthepowersupply.
ToallowyoutoselectthebestpossibleenergysupplyforyoureDRAULICdevice,neither
thebatterynorthepowersupplyformpartofthedeliveryscope.Youwillndsuitablebat-
teriesandpowersuppliesintheHURSTaccessorieslist.
eDRAULICdevicescomewithstandardlightttingstofacilitateworkunderpoorlight
conditions.
Thelight-emittingdiodesattachedontheoperatingsidelightuptheworkarea.The
mainswitchhasalsobeenequippedwitharinglight,sothatyoucanimmediatelydetect
whetherthedeviceisswitchedonornot.Whenexchangingthebatteryorpowersupply,
theconnectionslotwilllightupforapproximately30seconds.

6.1 Safety notes
Before rescue work can commence, the object must be stabilized in its current position.
Ensurethattheobjectstobeworkedonareadequatelyunderpinnedand/orsupportedto
ensurethatthereisnoriskofslidingorshifting.
Worldwide safety guidelines pertaining to the specic country must be observed and
compliedwith.
WARNING / CAUTION / PLEASE NOTE!
HURSTeDRAULICdevicesarenotexplosion-protected!
Whenusingthedevicesinpotentiallyexplosiveenvironments,the following
mustbeexcluded:
 - thatthedevicecouldtriggeranexplosion.
 - thatworkingwiththedevicecouldtriggeranexplosion;e.g.sparksmayresult
fromcuttinganobject.
TheresponsibilityforexplosionpreventionorforrulingoutworkwithaneDRAULIC
devicelieswiththeoperatorofthedeviceorwiththepersonresponsibleatthe
placeofuse.
When working in areas at risk of explosion, all applicable legal,
national and international regulations, standards and safety rules
for avoiding explosions must be observed without restriction!
Thefollowingaretobewornwhenworkingwiththerescueequipment:
- protectiveclothing,
- safetyhelmetwithvisororprotectivegoggles,
- protectivegloves,
- and,ifnecessary,earprotection.
Beforeoperatingtherescuedevice,youshouldensurethatnoparticipantsorbystandersare
atriskfromthemovementsoftherescuedeviceorfromyingfragments!Avoidunnecessary
damagetopropertybelongingtoothersortoobjectsnotinvolvedintherescueordamage
causedbyyingfragments.
Note on the operation of the eDRAULIC with a rechargeable battery:
IftherechargeablebatteryremainsintheeDRAULICdevicewiththemainswitchon,but
withoutactivatingthestargrip,therechargeablebatterywillswitchitselfo󰀨aftersometime
(approximately10-60minutes,dependingonthetypeofbattery).Ifthestargripisthen
activated,theeDRAULICdevicewillnotswitchitselfon.
Inordertoresumeworkwiththedevice,theeDRAULICdevicemustrstbeswitchedo󰀨at
themainsandthenswitchedonagain.
Alternatively,thecapacitydisplayontherechargeablebatterycanbeactivatedorthebattery
maybebrieyunpluggedandrepluggedagain.

16
It is strictly prohibited to reach into the path of the
rescue device (e.g. between the blades and the material/
object to which the force is to be applied)!
CAUTION / PLEASE NOTE!
The strong e󰀨ect of the force of the rescue equipment during operation could
causepiecesof thevehicleto break o󰀨ory o󰀨,posingadanger topersons.
Those not involved in the rescue operation should therefore keep at a safe
distance appropriate to thesituation.Any trapped or enclosed persons must
beprotected.

Removing the spreader tip
Step 1:
Toremovethespreadertips,rstpushoutbolt“A”alittle,usingangeroranobject.Afair

6.3 Spreading
Usethefrontofthetipsonlytoincreaseanexistinggap.Toincreasegripandtoavoidhaving
thetipssliporbreakoutoftheparttobeprocessed,thegripshouldbereappliedatanearly
stage.Thehighestforcedevelopsintherearareaoftheplug-ontiporintherearspreading
areaofthecombinationblades.
WARNING / CAUTION / PLEASE NOTE!
The light metal alloy arms may not be damaged.

Step 2:
Theboltcanthenbegrippedbytheangeandpulledoutuptothelimitstop.Thelimitstop
willpreventtheboltfrombeingpulledoutentirely.Thismeansthatitcannotbelost.
Step 3:
Pullthespreadertipforwardstoremoveit.
Attaching the spreader tip:
Attachmentofthespreadertiptakesplaceinthereversesequence.
Ensurethattheboltisalwayscompletelypushedinandengages.Ifthebolthas
notengaged,thismayresultinthetipinadvertentlycomingloosewhileinuse.
Thisinturncouldresultindamagetotherescueequipment.Therescuedevice
couldalsosliporpartscouldbeungo󰀨,resultingininjuriestoboththeoperator
andthecrashvictim.
Caremustalsobetakenthattheboltdoesnotinadvertentlycomeloosewhile
thedeviceisinuse.
