NSK Presto Aqua PRA-HP Handpiece With Coupling

Direction to Use

• Connect the handpiece hose to the coupling joint on the front face of the unit.
• Install the handpiece by pulling the ring of the coupling joint and aligning the positioning pin with the hole of the nose hood of the cartridge. Push it in straight.
• To remove the cartridge, loosen the cartridge retainer and hold the bur. Pull out the cartridge toward the front, ensuring that the O-ring placed on the rear bearing is also removed.
• For maintenance of the unit, observe the filter bowl through the inspection window and extract any retained water by inserting a finger from the base plate.
• To access the rotor shaft, hold it down and use a wrench (with a square hole or U-shaped hole) on the wrench mounting at the end of the rotor shaft. Turn the wrench in the direction indicated.
• To remove the chuck, after loosening the rotor shaft nut, push it out from the back using a test bur or shank of the bur. The guide bush can also be removed.
• When mounting a new cartridge, align the water and chip pipes and the positioning pin with the hole of the nose hood. Push it in straight.
• Ensure that the chuck and guide bush is securely in place before using the handpiece.
