Safety Information
• W ARNINGS:
The Xenon Headl amp s ys tem generat es up t o 28,000 volt s . Make sure t hat t he headl amps are swit ched off beforeworki ng on the sys tem. Fai lure to foll ow t his i ns t ructi on may l ead to fat al it y.
The followi ng s afety precaut ions mus t be fol lowed when working on t he Xenon Headl amp Sys tem:
DO NOT att empt any procedures on t he Xenon Headlamps or circui ts when the sys tem is energi zed.Handl ing of t he xenon bul b mus t be performed us i ng sui table protect ive equipment, e.g. gl oves and goggles . Theglas s part of t he bulb mus t not be t ouched.Only operat e t he lamp in a mounted condit ion i n t he reflect or.All s afet y procedures and precaut ions mus t be foll owed to prevent pers onal injury.
CAUTION: Xenon bulbs mus t be dis pos ed of as hazardous was te.
There are ins t ructi ons on the correct procedures for Xenon Headlamp Sys t em repai rs in t he manual, refer to secti on 100-00- General Informat ion, Standard W orks hop Pract ices of t he works hop manual .
