Removal Procedure

    Caution: Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:

       • Turn off the lamp switch and allow the bulb to cool before changing the bulb.
       • Leave the lamp switch OFF until the bulb change is complete.
       • Always wear eye protection when changing a halogen bulb.
       • Handle the bulb only by its base. Avoid touching the glass.
       • Keep dirt and moisture off the bulb.
       • Properly dispose of the used bulb.
       • Keep halogen bulbs out of the reach of children.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener.
