WARNING
Before servicing, lockout/tagout the main electrical service to the booth.

• If you use Booth Shield: Score around the light and peel off the Booth Shield covering.

Make sure to support the light cover when removing the last screws.
3.
Pull the light cover away from the panel and place the cover in a safe place.

If you do not use a protective covering on the lights, you might have to clean overspray from the light
cover and panel before you can remove the light cover.

Rotate the tube 90 degrees to free the bulb from the lamp holder and remove the burned-out light bulb.
NOTE
Two spring-loaded holders keep the tube in place.

Replace the bulb by pushing one end of the new tube into one of the two spring-loaded holders, sliding
the other end into the other holder, and then rotating the tube 90 degrees to lock in place.
6.
Replace the light cover, ensure the alignment of the interlocking safety switch, and then secure it with
the eight (6 mm x 20 mm) cap-head screws.

Once all light covers have been installed and the booth is safe to operate, remove the lockout/tagout
and apply power to the booth.
