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 O-rings from the head of the handpiece and the head cap.

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.

Take Insert 2 and make sure that screw is recessed into the hole. Place the rear of the turbine on the insert and slowly tighten screw until you feel it make contact with the turbine. Place Insert L2 under bearing ram.

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 in the center of Insert B with the bur going down through the hole in the center.

Locate the EZ Push Button Protector. 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. The spindle and protector will fall down into the tray below.

Inspect the impeller and autochuck for any damage. If damage is detected contact ProScore for replacements.

Open your rebuild kit and pick up one of the bearings. Place bearing on the end of your finger with the black side up. Gentle seat the rear of the spindle in the center of the bearing. If the spindle slides easily through the bearing us EZ Tight to hold it on.

Feed the blank bur up into the spindle ram on the left once more and hold in place. Slowly pull the handle down until the rear bearing meets Insert B. Make sure everything is aligned and gently press the rear bearing onto the spindle. You will feel the bearing come to a stop because the spindle is stepped in the center. DO NOT FORCE PAST THIS POINT WHEN YOU MEET RESISTANCE!

Remove the assembly from the spindle ram and look at the placement of the spindle in the bearing. The back of the spindle should stick out slightly through the back of the bearing. If spindle is recessed in the bearing repeat this step.

Hold the spindle so the bur points up and drop the impeller over the bur. Before pressing the impeller on check the direction. With the bur pointing towards you the blades should point clockwise.

If slant is correct feed the bur up into the Bearing Ram and hold in place. Slowly pull the handle down until the rear bearing meets Insert 2. Verify the end of the spindle is aligned within the hole in the center of Insert and then press the impeller down until it stops. If the impeller is riding loosely on the spindle contact ProScore for replacement.

Locate the front bearing and drop it over the bur. The black side of the bearing should face down towards the impeller. Repeat the pressing procedure from Step 7. If the front bearing is riding loosely on the spindle use EZ Tight to hold it on.

Install the new O-rings into the head and head cap. Now seat the rebuilt turbine into the head cap and install into handpiece. Make sure that the bur releases and the turbine rotates freely. If turbine is binding or the head cap heats up while running, remove the turbine and check for debris and the positioning of the turbine then re-install. If problem persists contact ProScore for tech support.
