After reviewing the training video and STEP-by-STEP instruction sheet, install the blank bur provided with your EZ Press. Tap the bur against the counter and try to pull it out using your fingers. If bur pulls out call ProScore for replacement spindle/collet.

Loosen head cap using appropriate cap wrench and remove turbine. If head cap and turbine come out together, separate and set head cap aside. Using an explorer remove and discard the washer and o-ring in the head cap and the washer and o-ring in the handpiece.

Inspect the head and head cap for debris and clean thoroughly using a cotton swab and handpiece cleaner. If any debris is overlooked the turbine may not fit back into either the head cap or head and may bind.

Place Insert C under the spindle ram and Insert #1 under the bearing ram.

Place turbine in the center of insert C with the bur going down through the hole in the insert. Locate the EZ Push Button Protector that was included with your EZ Press. Feed the skinny end up into the spindle ram and hold in place. Slowly pull the handle down until the protector meets the rear of the spindle and covers the button. Verify all parts are aligned. Pull down on the handle firmly to push the rear bearing and impeller off of the spindle.

Remove Insert C and place Insert B underneath the Spindle Ram. Pick up the turbine and feed the blank bur up into the Spindle Ram. While holding the turbine in place slowly pull down on the handle until the spindle goes through the hole in insert B and the front bearing is lying flat on the surface, then press the spindle out of the bearing.

Discard the old bearings. Inspect the impeller for any damage. If any damage is detected contact ProScore for replacement.

Pick up the spindle and hold it so the bur points up. Drop the bearing over the bur so the shielded or silver side of the bearing faces down, away from the bur and the black side faces up.

Once the bearing is in position feed the blank bur up into the bearing ram. Slowly pull down on the handle while holding the turbine in place until the rear of the spindle meets Insert #1. Gently press bearing down the spindle until it stops at Insert #1. If the bearing is riding loosely on the spindle use EZ Tight to hold it on

Hold the spindle so the bur points up and drop the impeller over the bur. Feed the blank bur up into the bearing ram. Before pressing the impeller on check the direction. The impeller should have its blades cupping to the RIGHT. If slant is correct feed the bur up into the bearing ram on the right and hold in place. Slowly pull the handle down until the rear bearing meets Insert #1. Verify the end of the spindle is aligned with the hole in the center of Insert #1, then press the impeller down until it comes to a stop. If the impeller is riding loosely on the spindle contact ProScore for replacement.

Locate the front bearing and drop it over the bur so the shielded or silver side is facing up towards the bur. Feed the blank bur up into the bearing ram Repeat pressing process until bearing comes to a stop when it reaches the impeller. If bearing is riding loosely on the spindle use EZ Tight to hold it on.

Place the brass washer in the handpiece head followed by one o-ring. Then place the silver washer followed by the last o-ring into the headcap. Seat the rear of the turbine into the head cap and install into the headpiece. Tighten cap down completely and make sure the bur rotates freely then test the performance. If the head cap heats up while testing stop and contact ProScore Tech support.
