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. Separate head cap and turbine. Remove and discard the 2 o-rings, and 2 spring washers.

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.

Locate one of the 3 holes below the ProScore Label on the EZ Press II. Loosen Insert 2 and place it over the top of the turbine. Press gently down on the turbine and turn the 2 Insert clockwise until you feel it just touch the chuck then turn the 2 Insert slightly counterclockwise. Place 2 Insert under bearing ram on the right.

Pick up the turbine and feed the blank bur up into the Spindle Ram. While holding the turbine, slowly pull down on the handle until the rear bearing goes into the hole and the impeller is sitting flat.

Pull down firmly on the handle and the spindle with the rear bearing still attached will be pressed out and fall into the tray below.

Remove Insert C and install Insert B on the left side. Retrieve your spindle and rear bearing and place it in the center of Insert B with the bur going down through the hole in the center.

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 and pull down on the handle firmly to push the rear bearing off of the spindle.

Inspect the impeller for any damage. If any damage is detected order a replacement from ProScore.

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 2. Gently press bearing down the spindle until it stops at Insert 2. If the bearing is riding loosely on the spindle use EZ Tight to hold it on. If spacer washers were present slide one of them onto the spindle with finger pressure until it touches the bearing.

Locate your impeller and pick up your spindle that you just pressed the rear bearing onto. Hold the spindle so the bur points up and drop the impeller over the bur with the blades cupping to the RIGHT. Press impeller until it stops at the bearing. Slide the second spacer washer on if it was present

Locate the front bearing and drop it over the bur so the shielded or silver side is facing up towards the bur. 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. The turbine is now rebuilt.

Place the spring washer into the head then the o-ring. The place a spring washer and followed by an o-ring into the head cap.

Seat the rear of the turbine into the head cap the install turbine into the head of the handpiece. Tighten cap down completely and make sure the bur rotates freely and releases when the button is pushed.

If the head cap heats up while testing remove the turbine and re-inspect the head with an explorer to make sure no debris was overlooked. If clean then contact for ProScore for tech support.
