1.Remove the top head cover as described under “Accessing parts” on page 21.
2.Turn the gobo wheel until the easiest access to the desired gobo position is obtained. Turn the color wheel until the open position is over the gobo position.
3.Tilt the head so the lens points down. Push the gobo and retaining spring out of the back of the holder. Avoid letting the spring and gobo fall into the head.
4.Insert the new gobo. See below for proper gobo orientation.
5.Insert the retaining spring with the bend facing out, away from the gobo. Working through the open position in the color wheel, push the gobo and spring all the way down into the gobo holder.

With a little practice, this method is faster than the above method.
1.Turn the gobo wheel until the easiest access to the desired gobo position is obtained. Turn the color wheel until the open position is over the gobo position.
2.Turn the gobo holder until you can see the tab on the holder retaining spring.
3.Grip the tab on the retaining spring with a pair of small (needlenose) pliers. Place your index fin- ger over the spring to prevent it from falling into the fixture. Open the spring and remove it from the gobo holder.
4.Remove the gobo holder from the bearing by pulling it forwards towards the lens.
5.Push the gobo and gobo retaining spring out of the holder.
6.Insert the new gobo. See below for proper gobo orientation. Insert the gobo retaining spring. The bend in the spring faces out, away from the gobo. Push the gobo and spring all the way down into the gobo holder.
7.Replace the gobo holder in the bearing. Do not force the holder into the bearing: it will go in eas- ily if it is installed straight.
8.Grip the retaining ring by the tab with the pliers. Place your thumb on the back of the gobo holder to press it all the way down in the bearing and use your index finger to hold the other end of the spring on the holder. Open the spring and place it in the groove.

4.To place a gobo in the wheel, first turn the gobo so that the black side faces the front and the reflective side faces the lamp. Then, using your thumb and forefinger, slide the gobo into posi- tion between the spring clips on the back of the gobo wheel.
5.Verify that the gobo is fully seated in the recessed groove by gently sliding it back and forth. If the gobo is seated correctly, you will be able to feel a tiny amount of movement.
