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 slinger and 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 and Insert #1 under the bearing 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 rear bearing goes down into the hole in Insert C and the impeller is lying flat on its’ surface. Once the turbine is aligned pull down firmly on the handle. The spindle with the rear bearing still attached will be pressed out and fall into the tray below. The impeller, old front bearing and slinger will remain sitting on Insert C.

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. The rear bearing will catch on the insert and prevent the spindle from falling through.

Locate the EZ Push Button Protector that was included with your EZ Press. Feed the skinny end up into the spindle ram on the left side of the press 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 or tap on the handle firmly to push the rear bearing off of the spindle. The spindle and protector will fall down into the tray below. Now the turbine is completely disassembled.

Discard both old bearings and slinger. Inspect the impeller for any damage. If any damage is detected contact ProScore for replacements.

Open your new rebuild kit, pick up one of the bearings and try to get it started on the rear of the spindle with your fingers. The black side of the bearing should face bur end. If the bearing is loose enough to push all of the way on with just your fingers use 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!

Hold the spindle so the bur points up and drop the impeller over the bur. 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. The black side of the bearing should face down towards the impeller. Verify alignment. Repeat the pressing procedure. If the front bearing is riding loosely on the spindle use EZ Tight to hold it on.

Locate the slinger and drop it over the bur so flat, smooth side is facing the front bearing. Repeat the pressing procedure but before applying any pressure it is a good idea to slowly rotate the impeller while pressing to ensure the slinger goes on straight. If the slinger is crooked at all when you begin to press on it damage will occur. If slinger is riding loosely on the spindle use EZ Tight to hold it on.

Install the new O-rings from the rebuild kit into the head cap and head of the hand piece. Now seat the rebuilt turbine into the head cap and install into hand piece. Make sure that the bur releases and the turbine rotates inside of the head. If turbine is binding even though all debris has been removed or the head cap heats up while running STOP and contact ProScore
