4. Functional description
4.1 Description
The spreaders 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spreader
arms.Thismovementcanbeusedtospreadopen,squeezeorpullopenobjects.
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.

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.IntheFederalRepublicofGermany,regularsafetyinspectionsaccordingto
the regulations of the Gesetzlichen Unfallversicherung (GUV; ‘Legal accident insurance’)
aremandatory.
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 spreader arms 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.
6.2 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.
WARNING / CAUTION / PLEASE NOTE!
