CAUTION • PRESTO AQUA LUX is a handpiece used in dental laboratories for cutting without heat generation when performing fine work on porcelain teeth, porcelain, and ceramics. Do not use for other applications. • Do not modify or disassemble as performance and safety may be seriously affected. Contact your dealer for repairs and/or service. • Take care not to drop the handpiece or Control Unit. Make sure the unit is situated on a flat and stable surface. • Observe the permissible bur speeds as recommended by the manufacturer. Failure to do so may result in damage or injury. • Do not use oscillating, bent, worn or damaged burs as they may fracture and cause injury. • Do not turn the Chuck Release Ring whilst the handpiece is running as this may damage the mechanism. • Never lubricate the handpiece, it uses a grease filled bearing and additional lubrication may cause damage. • Pay careful attention to rattling, vibration, noise and heat. Check for any irregularities by running handpiece before use. Contact your dealer immediately if any abnormalities are noticed • The optimum air pressure is 0.25~0.3MPa. Using higher pressure may cause excessive rotation speeds leading to premature bearing failure. • Remove any water or debris found in the filter of the Control Unit. • Always use clean, dry burs. Contamination, deposits or debris in the chuck can lead to failure of the mechanism. • Insert bur even when handpiece is not in use. • User is responsible for operation, maintenance and safety. • Do not wash, wipe or submerge the handpiece in any highly acidic or corrosive liquids. • Do not use this Control Unit or turbine in the room of the farmable gas. • Do not use this Control Unit around the equipment that the remarkably electric noise occurs. It may cause a malfunction or breakdown. • Install the Control Unit that cutting oil or water do not hang in it. It may cause malfunction or short circuit. • Wear protection glass, glove, ear piece and dust mask for your safety. • Place equipment so that the power supply cord can be swiftly pulled out in case of emergency. • Do not disassemble or alter the product by yourself. • Be careful not to be injured by the grinder or bur. • Be sure to turn the power off before cleaning and maintenance of the handpiece.

NOTICE • Do not power off the Control Unit until turbine is completely stopped. • Only use with original power supply cord. In case of damage, contact NSK / Nakanishi service center. • Equipment to be sent back to maufacturer for servicing / repair.

(7) Installation and Removal of Water Filter Set (Use of Main Water) Push the hose of the water filter set (the end with the water filter) into the tap water connector on the back of the Control Unit until it is securely held in place as shown in Fig. 10. Check if the hose is securely held in place by slightly tugging it after connection. Connect the other end of the hose to the tap water line.

• When Tap water is used, the water pressure may differ depending on the location, resulting in varying water supply; therefore adjustments may be necessary. • Leaving this product for a long time after using it with fine water mist may cause air ingress in the handpiece hose. This could result in a slow down the water flow when starting up the handpiece. In this case, turn the water volume up fully to clear the line and reduce again as necessary.

(5) Adjustment of Chip Air (when water supply is used) White Ring

Water Connector

Check the spray condition and adjust the amount of Chip Air with the Chip Air Adjustment Knob. Increasing the chip air results in water turning from jet to spray and finally to fine mist. Decreasing the Chip Air has the reverse effect.
