WASHINGTON - Altec Industries Inc. is recalling 103 AT40M/P aerial devices manufactured from June 2007 through October 2009 for use on work trucks.

These units have fiberglass arm links that may eventually lose electrical isolation performance. As a result, the links may begin to conduct current, posing an electrical shock risk to an equipment operator, according to the National Highway Traffic Safety Administration.

Altec will replace the link free of charge. The safety recall is expected to begin in June.

Owners can reach Altec at (877) 462-5832.
