27 Section V Operation axcs Chair Mounted Unit Delivery System The axcs CMU offers the following design features: Operation of three handpieces and a syringe. Drive air and coolant water may be adjusted individually for each handpiece. Foot control toggle valve allows wet or dry cutting. Master switch turns entire unit ON and OFF. Easy cleaning and disinfecting. Master Switch Controls Traditional & Euro-Style Head The master toggle switch located in the rear of the delivery unit controls the ON/OFF function of air, water and electricity to the entire unit. Flip the toggle switch to the right to turn ON the unit. IMPORTANT: At the end of each work day, and anytime the unit is unattended, make sure the master control switch is in the OFF position. An automatic CUT OFF, can be demonstrated by placing tubing in the hanger and disabling operation for that position. Rotate Handpiece Holder Set Screw Instrument Hanger The handpiece holder angle can be adjusted by using an Allen wrench to loosen two set screws and rotating the holder to the desired angle; then retightening the screws. An oil collector/filter is designed to collect oil from the handpiece exhaust air. Periodically check the filter for cleaning or replacement by lifting the delivery head cover and removing the screws that secure the filter cover. Master ON/OFF Switch Swing-Away Instrument Hanger Traditional Head This feature s design allows the following functions: The entire instrument hanger bar can be moved to the left or right to provide easy access to the optional tray on top of the delivery head. Grasp the delivery head with one hand; with the other hand, grasp the instrument hanger bar handle and move it to the left or right. Euro-Style Head Oil Collector/ Filter This feature s design allows the following functions: The multi-positional tray pivots around from left to right.

28 Section V Operation Handpiece Coolant Water Spray Coolant water spray to all the handpieces can be turned ON or OFF using the toggle switch located on the foot control. The coolant spray volume is individually regulated for each handpiece as follows: 1. Locate the water coolant valves found underneath the delivery head. Water Coolant Valves Handpieces and syringe instruments conveniently lay in four recessed areas on top of the delivery head cover. Delivery Head Positioning The horizontal and vertical location of delivery head can be varied by doing the following: To vary the horizontal location, push or pull the instrument hanger bar handle. To raise the delivery head, lift up the instrument hangar bar handle. Brake Release Button (Traditional Delivery Head Shown) Air Pressure Adjustment Screws 2. While operating the handpiece, turn the valve counterclockwise to increase the volume of coolant water spray. To decrease the volume, turn the valve clockwise. Air Pressure Air pressure to each handpiece can be adjusted to the manufacturer's specifications by following the air pressure instructions in Section IV Testing under the heading Handpiece on Page 24. NOTE: These procedures must be done while: The master switch is in the ON position, The handpiece is out of its holder and The foot control is fully depressed. To lower the delivery head, depress the brake release button, lift slightly on the handle and push the head down using the handle.

At the end of the day, turn the master ON/ OFF valve to the OFF position and clean the instrumentation. Each morning, turn the master valve ON and check the air and water system for proper operation using the three-way syringe. High-Volume Evacuator With the high-volume evacuator vacuum valve in the OFF position, disconnect the valve. Using a brush, clean the interior of the valve under a faucet, and rinse thoroughly. Saliva Ejector Disconnect the saliva ejector valve from the tubing and repeat the procedure described for the highvolume evacuator. Solids Collector To clean the solids collector, located at the instrument end of the assistant's arm, do the following: NOTE: It is recommended that puncture-resistant nitrile gloves be worn for this procedure. 1. Close the vacuum ON/OFF valve. 2. Push the lever on the saliva ejector downward to equalize pressure. 3. Remove the lid by lifting it straight up. 4. Grasp the stem on the basket and lift the basket straight up. 5. Empty debris and wash out the basket with warm water, then replace the basket and lid. 6. Open the vacuum ON/OFF valve. NOTE: After cleaning the saliva ejector, high-volume evacuator and solids collector, evacuate two cups of Vac-U-Ez cleaning solution (one cup each) through the highvolume evacuator and saliva ejector to sanitize the system. NOTICE Cleaning brushes and Vac-U-Ez solution can be ordered through DentalEZ dealers. Disinfecting Liquid disinfectants are recommended for use on all axcs CMU external surfaces and should be applied using a soft, clean cloth.
