Using the headcap wrench that is provided with the handpiece, remove the headcap by turning it counter-clockwise.

Remove the turbine from the handpiece- if the turbine does not come out with the headcap removal, push the turbine out through the rear, using the bur.

Inspect the interior of the turbine chamber for cleanliness, O-rings and/or washers. Inspect the head cap to ensure that the turbine’s rear, black O-ring has been removed. If it is present, carefully remove the O-ring. Using Isopropyl Alcohol (I.P.A.) with a bristle brush and/or swab, clean the head cap. Ensure the head cap is clean and dry.

Remove any O-rings and/or washers from the turbine chamber. Clean interior of the head with I.P.A. using a bristle brush and/or swab. DISCARD AND REPLACE any O-rings that are hardened, no longer supple, or that allow loose movement of the turbine in the head or head cap, or vibration during running. DISCARD AND REPLACE and washers that are worn. After cleaning, ensure that the interior of the head is dry, clean and free of debris.

Gently clean all exterior surfaces of the turbine using I.P.A. and a bristle brush.

Place the turbine - chuck side down - against a hard flat surface. Grip the turbine and push down against the surface until you hear a click, then remove the bur.

Grasp the back of the chuck in front of the stack of small spring washers and remove the chuck assembly from the spindle. Gently clean the exterior of the chuck with I.P.A. and a small bristle brush. Gently clean the interior of the chuck with I.P.A. and a pipe cleaner.

Insert a pipe cleaner dampened with I.P.A. into the spindle hole as far as possible. Remove pipe cleaner from spindle and wipe debris from pipe cleaner. Repeat until pipe cleaner comes out clean.

Place the cleaned chuck assembly back into the spindle hole. Push the chuck in until it is fully inserted.

Place the turbine - chuck side down - against a hard, flat surface. Insert a bur into the spindle as far as it will go. (approximately halfway). Grip the turbine, push down against the surface, and slide the bur in the rest of the way.

Replace the O-rings (black O-ring at the chuck end of the turbine and the blue O-ring at the bur end of the turbine) and washers.

Add a few drops of Impact Air 45® autoclavable lubricant into the turbine chamber and insert the turbine. Use the bur to guide the spindle into the center of the hole. As the turbine begins to seat, apply firm pressure with a wobbling motion to seat the front O-ring. The end of the rear bearing should be flush with the open end of the turbine chamber.

Place the headcap on the back of the turbine cartridge so that it rests against the head. Using your fingers, turn the headcap clockwise with slight inward pressure until threads engage. Check to see that the cap is threading straight into the head and continue until finger tight. Continue to tighten the cap with a cap wrench while ensuring that the turbine spins freely.

Be sure to tighten headcap securely so that it does not loosen during operation.

If the turbine does not spin when cap is tight, remove turbine and re-inspect O-rings and washers. If problem persists- contact Palisades Dental for technical assistance.
