13 Section IV Testing NextGen Cart Delivery Unit Air Pressure 1. Flip the toggle valve to DRY at the foot control. 2. To adjust the individual handpiece drive air pressure to the manufacturer's specifications do the following procedure: a. Remove the handpiece from its holder. b. Insert an air pressure gauge as indicated in the illustration below. Tubing Handpiece Adaptor c. Hold the handpiece, fully depress the foot control and observe the amount of air pressure delivered to the handpiece. d. Locate the air pressure adjustment screws on the bottom of the delivery head chassis. Air Pressure Adjustment Screws Nut (Insert Air Pressure Gauge Here) Syringe If the unit is equipped with a syringe, first depress the air button and then the water button to test the flow. Electric Handpiece (Optional) The electric handpiece is actuated by air pressure. So make sure air pressure is present, verify the following: Master switch must be in the ON position All electrical connections must be made correctly The power module must be plugged in at the USC. Once the electric handpiece is lifted from the hangar bar holder, operation is similar to a standard handpiece. NOTE: For operation of the electric handpiece, see Section V Operation, Page 16. Fiber Optics (Optional) Follow the test procedures outlined in the instructions included in each fiber optic handpiece package. e. Turn the air pressure adjustment screw on the control valve of the appropriate handpiece (counterclockwise to increase pressure, clockwise to decrease pressure) until the hand-piece manufacturer's correct specification registers on the pressure gauge. 3. Repeat a. through e. in Step 2 to set the pressure for each handpiece. NOTE: If a low-speed handpiece is required, slide the coolant air and water restrictor over the lines on the appropriate control valve. 12 Installation, Operation and Care Manual

14 Section V Operation WARNING To prevent possible injury because of accidental operation, do not leave young children unattended. Instrument Hanger An automatic CUT OFF, can be demonstrated by placing tubing in the hanger and disabling operation for that position. Delivery System Some of the NextGen Cart delivery unit design features: Operation of three handpieces and a syringe. Drive air and coolant water may be adjusted individually for each handpiece. Lockout safety feature (optional) allows only one-at-a-time handpiece operation. An automatic cut-off switch in each handpiece holder section disables operation for that position. Foot control toggle valve allows wet or dry cutting. Master switch turns entire unit ON and OFF. Handpiece Holder Section Instrument Hanger Automatic Cut Off Switch Each handpiece holder angle can be adjusted by using an Allen wrench to loosen two set screws in the back of each section and rotating it to the desired angle; then re-tightening the screws. Master Switch Controls The master toggle switch controls the ON/OFF function of air, water and electricity to the entire unit. Flip the toggle switch to turn ON the unit. NOTE: On the Assistant version, the master switch is on the panel with the water bottle. Master Switch Set 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 work surface lid and removing the screws that secure the filter cover. CAUTION VERY 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. Oil Collector/ Filter Screws NextGen Cart Delivery Unit 13

15 Section V Operation Doctor Arm Adjustment Doctor Arm Positioning To adjust the up and down tension in the doctor arm, perform the following procedure: If the arm is too easy to move up and down or if the arm goes down by itself, turn the tension adjustment screw clockwise until the desired resistance is reached. If the arm is too hard to move up and down, turn the tension adjustment screw counterclockwise until the desired resistance is reached. Tension Adjustment Screw Rotation Adjustment Bolt If the arm is too hard to rotate left and right, loosen the rotation adjustment bolt. If the arm is too easy to rotate left and right, tighten the rotation adjustment bolt. Handpiece Coolant Adjustment 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 by using the coolant water adjustment valves located on the underside of the delivery head. NextGen Cart Delivery Unit While operating a handpiece, turn the coolant water adjustment valve counterclockwise to increase the volume of coolant water spray. To decrease volume, turn the valve clockwise. Coolant Air Adjustment Valve Coolant Air Adjustment Coolant Adjustment Valves The coolant air volume for all handpieces is regulated by using the coolant air adjustment valve found on the underside of the delivery head where applicable. While operating a handpiece, turn the coolant air adjustment valve counterclockwise to increase the volume of coolant water spray. To decrease 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 Air Pressure on Page 13. 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. NOTE: When making necessary air pressure adjustments, refer to the air pressure gauge located at the side of the delivery head to check the approximate amount of air pressure delivered to the handpiece. Air Pressure Adjustment Screws Air Pressure Gauge 14 Installation, Operation and Care Manual

16 Section V Operation Flush System It is recommended that the tubing of each handpiece used be flushed after each patient. 1. Hold the handpiece tubing over a sink, cuspidor or open vacuum line. 2. While facing the front of unit, move the FLUSH valve toggle located at the rear of the delivery head to the left and hold it there for 20 seconds. Flush Valve Toggle Foot Control The speed of the handpiece is controlled by depressing the disk located on the foot control. A light pressure on the foot control disk causes a slow speed. Disk WET/DRY Toggle Valve Chipblower Full pressure on the disc causes the handpiece to operate at full speed. NOTE: Flushing the water line in the handpiece can be done by operating the FLUSH valve while either fully depressing or not depressing the foot control. Syringe The syringe is designed to deliver air or water, or a mixture of air and water, as required. To deliver water only, press the button on the syringe marked with a water drop symbol. For air only, press the button on the syringe with no marking. To get a spray mixture of air and water, press both buttons simultaneously. NOTE: Air and water flows are factory preset. NOTE: The coolant water spray ON/OFF function is also controlled by using the toggle valve on the foot control as described above. Chipblower If the handpiece utilizes coolant air, the chipblower is used to blow debris away from the cutting site by creating an air blast through the handpiece without causing the burr to rotate. To operate the chip blower, depress and hold down the valve on the upper right of the foot control. Fiber Optics (Optional) The fiber optics control is automatically activated by operating the handpiece using the foot control. NOTE: When the foot control is released, the fiber optics light will stay on for approximately ten seconds to allow inspection of the cutting site. NextGen Cart Delivery Unit 15
