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
If you have an replaceable chuck (OEM spindle) STOP and use the Lares 557 OEM instructions. Loosen head cap and remove turbine. If head cap and turbine come out together, separate and set head cap aside. Discard the 2 o-rings and wave washer.
Place Insert C under the spindle ram on the right.
STEP 2
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 2 under bearing ram on the right.
STEP 3
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.
STEP 4
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 and feed the skinny end up into the spindle ram and hold in place.
Slowly pull the handle down until the EZ Push Button 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.
STEP 5
Inspect the impeller and autochuck for any damage. If damage is detected contact ProScore for replacements.
STEP 6
Open your new rebuild kit, pick up the thinner of the two bearings and place on the front of the spindle with your fingers. The black side of the bearing should face bur end. If the bearing is loose enough to push on with just your fingers use EZ Tight to hold it on.
STEP 7
Feed the blank bur up into the bearing ram on the right and hold in place. Slowly pull the handle down until the rear bearing meets Insert 2. Make sure everything is aligned and gently press the rear bearing onto the spindle until you feel the bearing come to a stop.
STEP 8
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 with the hole in the center of Insert 2, and then press the impeller down until it stops. If the impeller is riding loosely on the spindle call ProScore for replacement.
STEP 9
Locate the front bearing and drop it over the bur. The dark 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.
STEP 10
Install the new o-rings into the head and head cap. Place the wave washer on front bearing. 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.
