INSTRUCTION FOR USE
1. The main reasons for accidents occurring during use of ladders
a) Loss of stability• Incorrectpositioning(leaningtheladderattheincorrectangle,openingastepladderincompletely)• Whenthebottomoftheladderslips(thebottomoftheladderisnotsecuredandslipsawayfromthewall)• Slippingtotheside,fallingtothesideandoverturningthetopoftheladder(theladderdoesnotreachhighenoughovertheuppercontactsurfaceoranunstableuppercontactsurface)
• Laddercondition(missinganti-slipfeet)• Comingdownaladderthatisnotsecuredatthetop• Terrainconditions(unstablesoftsoil,slopingterrain,slipperysurfacesorsoiledsolidsurfaces)• Unfavourableweatherconditions(windyweather)• Collisionwiththeladder(doororavehicle)• Unsuitableselectionofaladder(tooshort,unsuitableactivities)
b) Manipulation• Carryingtheladdertotheworksite(theladderfallingfromaverticalposition)• Assemblinganddisassemblingtheladder(theladderfallingfromaverticalpositionduringincorrectmanipu-lation,havingfingerspinchedbyanotherperson)
• Carryingitemsupordowntheladder(heavyorlargeitems,lossofstability)
c) The user slipping or falling• Unsuitablefootwear• Dirtyrungsorsteps• Theuser’sdangerousactions(climbingtheladdertworungsatatime,slidingdown
theside-rails)
d) Structural defect in the ladder• Conditionoftheladder(damagedside-rails,wear)• Over-loadingtheladder
e) Danger posed by electrical current• Unavoidableworkundervoltage(contactwhenestablishingadefect)• Positioningtheladderimmediatelynexttoelectricalequipmentundervoltage(elect-
ricalmainsabovetheuser’shead)• Laddersdamagingelectricalequipment(coversorprotectiveinsulation)• Incorrectselectionofthetypeofladderforelectricalwork

The following applies for modes 3) and 4):Only one person may work on the work platform and the total load must not exceed a weight of 150 kg! The platform is not constructed for climbing the actual structure, therefore you must use other safe means for ascending.The platform must not be used without the stabilisers attached. The platform is not equipped or structu-rally designed for work at a height above one meter, consequently use above the specified height limit is forbidden.
