How do I change the bulbs?

First turn off the machine and allow the bulb to cool down. Remove the bulb by grasping and pulling the bulb directly up. Remove the new replacement bulb from its box, and slide the new bulb in place. Do not touch the bulb with your fingers use gloves. The lamp operates at a high temperature and any finger marks will be "fired" into the surface of the quartz reducing the output and life of the lamp.
