SAFETYNOTES
1.1Operationofliftingplatforms
Thisliftisspeciallydesignedforliftingmotorvehicles.Usersarenotallowedtouseitforanyotherpurposes.Theapplicablenational
regulations,lawsanddirectivesmustbeobserved.
Onlyusersaged18orabovewhohavebeeninstructedonhowtooperatetheliftingplatformandhaveproventheirabilitytodosotothe
owneraretobeentrustedwithunsupervisedoperationofliftingplatforms.Thetaskofoperatingtheliftingplatformsmustbegrantedin
writing.
Beforeloadingavehicleontotheliftingplatform,usersshouldstudytheoriginaloperationinstructionsandfamiliarizethemselveswiththe
operatingproceduresinseveraltrialruns.
1.2Checkingoftheliftingplatforms
Checksaretobebasedonthefollowingdirectivesandregulations:

Thebasicsafetyrequirementsstipulatedinthedirective2006/42/EC
HarmonizedEuropeanstandards
Theapplicableaccidentpreventionregulations
Thechecksaretobeorganizedbytheuseroftheliftingplatform.Theuserisresponsibleforappointinganexpertorqualifiedpersonto
performchecking.
Theuserbearsspecialresponsibilityifemployeesofthecompanyareappointedasexpertsorqualifiedpersons.
1.2.1Scopeofchecking
Regularcheckingessentiallyinvolvesperformingavisualinspectionandafunctionaltest.Thisincludescheckingtheconditionofthe
componentsandequipment,checkingthatthesafetysystemsarecompleteandfunctioningproperlyandthattheinspectionlogbookis
completelyfilledin.Thescopeofexceptionalcheckingdependsonthenatureandextentofanystructuralmodificationorrepairwork.
1.2.2Regularchecking
Afterinitialcommissioning,liftingplatformsaretobecheckedbyaqualifiedpersonatintervalsofnotlongerthanoneyear.
Aqualifiedpersonissomebodywiththetrainingandexperiencerequiredtopossesssufficientknowledgeofliftingplatformsandwhois
sufficientlyfamiliarwiththepertinentnationalregulations,accidentpreventionregulationsandgenerallyacknowledgedrulesof
engineeringtobeabletoassessthesafeoperatingconditionofliftingplatforms.
1.2.3Exceptionalchecking
Liftingplatformswithaliftheightofmorethan2metersandliftingplatformsintendedforusewithpeoplestandingundertheloadbearing
elementsoftheloadaretobecheckedbyanexpertpriororreusefollowingstructuralmodificationsandmajorrepairstoloadbearing
components.
Anexpertissomebodywiththetrainingandexperiencerequiredtopossessspecialistknowledgeofliftingplatformsandwhoissufficiently

2.2Storage
Thepacksmustbekeptinacoveredandprotectedareainatemperaturerange0f‐10℃to+40℃.Theymustnotbeexposedtodirect
sunlight,rainorwater.
Stackingthepacks
Weadviseagainststackingbecausethepacksarenotdesignedforthistypeofstorage.Thenarrowbase,heavyweightandlargesizeofthe
packsmakestackingdifficultandpotentiallydangerous.
Ifstackingisunavoidable,useallappropriateprecautions:
‐neverstacktomorethan2metersinheight.
‐nevermakestacksofsinglepacks.Alwaysstackpairsofpacksinacrosspatternsothatthebaseisbiggerandtheresultingstackismore
stable.Oncethestackiscomplete,restrainitusingstraps,ropesorothersuitablemethods.
Amaximumoftwopackscanbestackedonlorries,incontainers,andinrailwaywagons,onconditionthatthepacksarestrappedtogether
andrestrainedtostopthemfalling.
2.3Liftingandhandling
Thepackscanbeliftedandtransportedonlybyusinglifttrucks.Thecenterofgravityandlashingpointsaremarkedonthepackaging.

4.2.2Allboltsshouldbefirmlyscrewedup.
4.2.3Donotplaceanyvehicleontheliftinthecaseoftrialrunning.
4.3GeneralInstallationSteps
Step1:Dismantlethepackageandplaceliftingplatformsintorecessedpitswithaforkliftandliftingstraps.
Raisetheplatformbyusingaforkliftand2liftingstrapsuntilthemechanicallockisengaged.Dismantletheboltsthatfixtheplatformand
itswoodenpackageandthenhoisttheplatformontotheexpectedinstallationsite.
Attention1:Avoidscratchingthepaintingsurfaceandhoses.
Attention2:Beforehoisting,makesurethehosesandwiresarewellprotectedagainstdamage.
Attention3:Itisnecessarytoholdtheplatformduringthehoistingprocess.Irrelevantpersonisnotallowedininstallationarea.
Step2:Connecthydraulicsystem.
ConnecttheoilhosestothepowerunitasperthediagramforoilhoseconnectioninAnnex3.
Attention:Connectasperthemarksonthehosesanddonotcontaminatethehydrauliccomponentsduringtheconnection.
Step3:Connectthepneumaticreleasesystem
ConnectthepneumaticreleasesystembythediagramofairhoseconnectioninAnnex4.
Attention:Donotcontaminatethepneumaticcomponentsduringtheconnection.
Step4:Connectelectricalwires.
RefertoAnnex2whenfixtheelectricalsystem.
Connectthewireconnectorsforraisingandloweringlimitswitches
Connectthepowersupplycabletoexternalelectricitysupply.

Step5:Fillwithhydraulicoil.
ONLYCLEANANDFRESHOILONLY.Liftmustbefullyloweredbeforechangingoraddinghydraulicoil.
Pour16litersofhydraulicoilintotheoiltank.Thelevelofoilshallreachthetippetsvolumemarkofthetank.
Runtheliftforseveralcyclesandaddmoreoiluntiltheliftingplatformcanreachitsmaximumheight.
Note：Astheviscosityofhydraulicoilmayhaveinfluenceontherunningspeedofthelift,itissuggestedusingNO.46hydraulicoilwhen
averagetemperatureofthelocationisabove18degreeCelsiusandusingNO.32hydraulicoilwhentemperatureisbelow18degreeCelsius.
Changetheoil6monthsafterinitialuseandchangeonceperyearthereafter.
Step6:Levelling
Checktheconnectionofthehydraulicandelectricalsystembeforelevellingoperation
Reviewoperationinstructionsandgetfamiliarwithliftcontrolsbyrunningtheliftthroughafewcyclesbeforelevellingoperation.
Attention:Leveltheplatformsbeforeconnectingmaxheightlimitswitchbecauseifnot,platformsmaynotrisetothehighestposition.
Theoperatorneedstoknowclearwhichlevellingvalvecontrolswhichplatform.Thiscouldbejudgedbythewaythattheoilhosewas
connectedorbytrialraisingorlowering.
