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
Remove bur from handpiece and replace with Autochuck Protection Bur. Loosen head cap using cap wrench and remove turbine. If head cap and turbine come out together, separate and set head cap aside. Using an explorer, remove the any 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 1 under the bearing ram.
STEP 2
Pick up the turbine and feed the autochuck protection bur up into the Spindle Ram. While holding the turbine in place, slowly pull down on the handle until the rear bearing is resting on Insert A.
Verify alignment, then pull down rmly on the handle. The spindle will be pressed out through the hole in the center of Insert A and fall into the tray below.
The spacer washer must be re-used and is not included in the kit.
STEP 3
Discard old bearings. Inspect the impeller and washer for any damage. If any is detected contact ProScore for replacement.
Examine spindle to verify that the inner-race of the old rear bearing has not remained on the spindle. It will look like a shiny ring with a groove in it. If the inner-race is still on the spindle, grasp it tightly with a pair of hemostats or diagnol cutters. Feed the bur up into the Spindle Ram on the left side of the press and repeat the pressing procedure, making sure that the ange on the end of your spindle clears the hole in Insert A. The inner-race will be pushed off of the front of the spindle.
STEP 4
Open your rebuild kit and pick up one of the bearings. Place it over the bur so that the wide flanged edge, or side with the dark ring faces up towards the bur.
Feed the bur up into the Bearing Ram on the right side of the press and hold turbine in place. Slowly pull down on the handle until the rear of the spindle meets Insert #1. Verify alignment, then gently press the bearing onto the spindle until it comes to a stop.
STEP 5
Locate your impeller and place it over the bur so that with the bur facing away from you or the blades slant to the right. Repeat the pressing procedure until the impeller comes to a stop.
STEP 6
Open your rebuild kit and locate the smooth rear bearing. It will be the smaller of the two. Place the bearing over the bur so the side with the visible balls faces down away from the bur.
STEP 7
Locate the other bearing and feed it over the bur so that the wide anged edge, or the side with the black ring will be towards the impeller. Repeat the pressing procedure.
Locate the tight spacer washer and feed it over the bur until it rests at the end of the spindle. Repeat pressing process. If this washer slides all of the way on by hand contact ProScore for replacement.
STEP 8
Place a quad o-ring on each of the bearings so the o-rings are seated on the flange of each bearing. Seat rebuilt turbine into head cap.
Hold the handpiece so the head points towards the ground and install the turbine and head cap. Check the bur for resistance us you tighten the head cap. If you notice any resistance, remove the turbine and re-install. If problem persists, call ProScore Tech Support.
