REQUIRED TOOLS

• Two small blocks of wood.
• One small flat blade screwdriver.
• One 1/32" thick gasket supplied with PRISMO - ZPTSPM-32
• One 1/64" thin gasket supplied with new prism - ZPTSPM-64

If the prism has not already been mounted, the first step is to mount the prism in the rotator. You will need two small blocks of wood as a support. Place the prism rotator on the blocks motor side up so that it sits slightly off the work table, (see figure #1). First place the 1/32" thick gasket into the prism ring. Next place the prism into the Prismo™, flat side facing you and the facets facing down and press in firmly. Then take the retaining ring and feed it into the groove just above the prism, making sure that it is fully seated in the groove. Start with the flat edge and work your way around to the slotted end, (see figure #2). Check to see if the prism slips. If you are having problems putting the retaining ring in and it pops out, take out the thicker 1/32" gasket and use the 1/64" thinner gasket. If the prism slips you will need to add the second 1/64" thin gasket along with the 1/32" thick gasket.

CHANGING THE PRISM

Be careful as you can chip or scratch the glass prism. At the slotted end of the retaining ring use the screwdriver to push the ring out of the groove ( make sure not to catch the glass or it will chip)push the retaining ring up and in toward the center of the prism to pull the ring out of the groove. Pull up on the retaining ring. Have a hand on the prism in case it pops out. Take out the prism and gasket. Because of different tolerances in the machining and the grinding of the prism and the gasket, the prism comes with a 1/64" thin gasket. You may not need it.

REASSEMBLY

Put the thicker gasket 1/32" in the prism ring. Next, place the prism into the Prismo™, flat side facing you and the facets facing down and press in firmly. Now take the retaining ring and feed it into the groove just above the prism, making sure that it is fully seated in the groove. Start with the flat edge and work your way around to the slotted end, (see figure #2).

Prism is too loose:
Add the second 1/64" gasket along with the 1/32" gasket.

Retaining Ring won't fit:
Remove thicker 1/32" gasket and use the 1/64" gasket.
