BEFORE YOU BEGIN

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.

STEP 1
STEP 1

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 the old wave washer 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 A under the spindle ram and Insert 0 under the bearing ram.

STEP 2
STEP 2

Place Insert C underneath the Spindle Ram on the press. Feed the blank bur up in to the Spindle Ram on the press. While holding the turbine in place, slowly pull down on the handle until the impeller is resting on Insert C. Verify alignment, then pull down firmly on the handle. The spindle and rear bearing will be pressed out through the hole in the center of Insert C and fall into the tray below. The front bearing and impeller will remain on Insert C.

 

STEP 3
STEP 3

Remove insert C and place insert A underneath the Spindle Ram repeat the pressing procedure.

STEP 4
STEP 4

Inspect the impeller and autochuck for any damage. If any damage is detected call ProScore for replacement.

STEP 5
STEP 5

Locate Insert 0 and place underneath the Bearing Ram of the press. Open your rebuild kit and locate the smooth rear bearing. It will be the smaller of the two and has visible balls on one side. Place the bearing over the bur so the side with the balls is facing away from the bur.

STEP 6
STEP 6

Feed the bur up into the Bearing Ram on the press and hold turbine in place. Slowly pull down on the handle until the rear of the spindle meets Insert 0. Verify alignment, and then gently press the bearing onto the spindle until it comes to a stop.

STEP 7
STEP 7

Locate your impeller and place it over the bur so that with the bur facing away from you the air would turn the impeller clockwise. Also, the end of the impeller with the shorter shank will be toward the bur. Repeat the pressing procedure until the impeller comes to a stop.

STEP 8
STEP 8

Locate the flanged front bearing and feed it over the bur so that the wide flanged edge or the side with the black ring will be towards the impeller. Repeat the pressing procedure.

STEP 9
STEP 9

Place one of the new O-rings directly on the step of the flanged front bearing. Seat the other O-ring into the groove in the head cap. Seat rebuilt turbine into head cap. Using an explorer, place the wave washer in the head so the wings are facing down.

STEP 10
STEP 10

Hold the handpiece so the head points towards the ground and install the turbine and head cap. Check the bur for resistance as you tighten the head cap. If you notice any resistance, remove the turbine and re-install. If problem persists, call Tech Support.
