1Scope
This technical specification provides an informative guide on care，maintenance and in-service testing requirements of aerial devices with insulating booms used for live working.
This specification is not a replacement for manufacturers’ recommendations but rather asupplement containing critical generic requirements. In all cases, the manufacturers’speci-fication and reasonable recommendations regarding use,care，maintenance,repairs andadjustments shall be adhered to.

Definitions
For the purposes of this technical specification，the definitions given in lEC 60050-651,specific to live working tools and equipment, and in lEC 61057,specific to aerial devices withinsulating booms for live working, as well as the following,apply.
3.1
competency
ability to undertake responsibilities and perform activities with regard to specified standards
3.2
formally trained and qualified person
competent person possessing the appropriate practical and theoretical knowledge and havingadequate skill and experience to enable them to perform the required duty,interpret theresultant information and, from that information, determine that the equipment or plant is safefor use, and report the importance of any defect found or suspected in relation to the safetyand continued use of the equipment or plant
4General
Aerial devices used for live working applications provide protection to the operator, and failuremay contribute to an incident. It is,therefore，important that a structured maintenanceprogramme be established and that operators be formally trained and qualified in care andmaintenance.
After the aerial device is put into service, periodic testing and in-service checking will ensurethat the characteristics of the equipment remain adequate for live working, and in accordancewith design specifications.
Maintenance and frequency of maintenance shall be determined on the basis of therecommendations of the manufacturer and with due cognizance of the aerial device duty cycleand environmental effects such as pollution and weather.
NOTE Manufacturers employ various techniques in the construction of the insulating booms,each with individualpeculiarities. The manufacturer’s specific recommendations regarding care and maintenance should be strictlyadhered to in all cases.
5 Care of insulating components
5.1Care whilst in transit
Platforms shall be returned to their normal position. If applicable, the jib shall be removed orretracted.The upper boom shall be folded and the lower boom lowered so that both rest ontheir respective supports. Extensible booms shall be fully retracted.Boom tie-down strapsshould be used to prevent the boom being damaged whilst in transit. Where articulated typesare to be used “off road”, consideration should be given to both upper and lower boom tie-down straps.
When the unit is being moved,the boom hydraulic operating system should be disengaged,and，in the case of hydraulically levelled platforms，the free-swing of the latter shall beensured.
