9. Ensure the following are plugged into the power strip: 24 VAC Transformer (if available) and compressor.
10. Turn on power strip to supply power to cart.
11. Connect male quick connect to compressor (See Figure 7.1). This will provide pressure to LED High Speed, Low Speed and LED Piezoelectric Handpieces and Air & Water systems.
12. Gauges are visible to monitor pressures. The following pressures provide optimum efficiency and safety of the unit. Simply remove a handpiece and depress foot pedal to verify pressure.
Filter Housing / System Pressure: 65 - 75 psi (Warning: Do not adjust pressure above 75 psi).
LED High Speed Handpiece: 35 - 40 psi
Low Speed Handpiece: 25 psi
Water Pressure: 25 - 30 psi
LED Piezoelectric Handpiece: 58 - 60 psi
13. Operating pressures for each handpiece have been factory set; however, minor adjustments may be required due to shipping - see “Adjustments” below.
Adujstments After Shipping
A. Verify the air pressure discharge from the air regulator / filter (gauge located between the air tank and the compressor motor on the front of the unit) is at 65 - 70 psi (See Figure 8.1).
B. If adjustment is needed, pull up on the air regulator valve to unlock the adjustment knob, then turn the knob clockwise to increase the pressure and counterclockwise
C. Verify the water system air pressure is reading from 25 - 30 psi, See diagram on Page 5 (Item 5). The pressure regulator is located inside of the cart storage top. Loosen the lock nut, then turn the adjustment stem clockwise to increase pressure and counterclockwise to decrease the pressure. Once the proper pressure has been set, retighten the lock nut.
Note: The pressure regulator is not self-bleeding and pressure will have to be relieved by turning the water bottles off and on.
D. Handpiece operating pressure adjustments are made by turning the three adjustment screws located on the left side of the cabinet located on left front side of the unit (See Figure 8.2). Adjust operating pressures as follows:
➢ High speed operating air pressure is 35 - 40 psi. To verify pressure, remove handpiece, depress foot pedal and observe pressure gauge on front panel above handpiece rack. If adjustment is needed, turn the far right adjustment screw clockwise to decrease, or counterclockwise to increase, pressure while depressing the foot pedal. The adjustment knob is very sensitive, so a minor adjustment will cause a significant change.
➢ Follow the same procedure as above to adjust the Low Speed Handpiece (the middle adjustment knob) to 25 psi.
LED High Speed & Low Speed Handpieces
The handpieces have pre-designated holder positions as follows: High Speed or High LED High Speed far left, Low Speed second from left, LED Piezoelectric Scaler second from right and Air / Water Syringe far right (See Figure 9.1).
Note: Handpiece holder positions have been temporarily labeled. The labels can be removed at any time.
Individual handpieces are ready for use when selected and lifted from the holder. Handpieces other than the Air / Water Syringe, must be returned to their pre-designated holder positions before picking up another handpiece for use.
Oil LED High Speed and Low Speed Handpieces prior to first use, and oil before and after daily use. Oil is placed into the smaller of the 2 large holes at base of the handpiece (See Figure 9.2). Use of spray cleaner and lubricant such as Bio Lube™ is recommended. If using simple oil as a lubricant, place four drops into appropriate hole, reattach handpiece and flush through with air for 20 seconds. Failure to oil after each use will void the warranty.
Note: Handpieces should be cleaned with Bio Lube™ cleaner weekly.
Once a week remove the bur blank and place two drops of oil into the turbine.
Always leave a bur or rod insert in the LED High Speed Handpiece when not in use. Failure to do so voids the warranty. Burs are changed by a push button on the handpiece
(See Figures 9.3, 9.4 and 9.5).
The LED High Speed Handpiece can be used with or without water. If water is desired, turn the far left toggle switch to ON, see diagram on Page 4 (Item 12). To increase water flow, turn the adjustment knob to the left, or counter-clockwise; to decrease water flow turn to the right, or clockwise. See diagram on Page 4 (Item 13).
The Low Speed Handpiece is not fitted with a water supply. Depressing the foot pedal activates drive air for the handpiece motor. This handpiece is used for polishing.
Note: The Low Speed Handpiece must be aligned as pictured for proper operation (See Figures 9.7 and 9.8)
Air/Water Syringe
To operate the Air / Water Syringe, lift the syringe from the holder and depress the respective button(s) on handpiece to obtain either air or water, or both.
Built-in LED Piezoelectric Scaler and Handpiece
To connect the LED Piezoelectric Handpiece to the cord, align the four pins and water supply port on the handpiece with the cord. Insert the handpiece into the cord coupler, and gently, but firmly, push the handpiece into the cord coupler. Do not twist, turn or unscrew the handpiece while inserting into or removing from the cord coupler. This will break the connectors in the handpiece and cannot be repaired and will void the warranty.
To operate the LED Piezoelectric scaler, press the LED Piezoelectric Power switch to ON, see diagram on Page 4 (Item 8). Lift the LED Piezoelectric Handpiece from the holder, set the power adjust and water flow and press on the foot pedal. Water should be adjusted to a fine mist (See Figures 10.1 and 10.2).
The built-in LED Piezoelectric scaling system power settings can be used in a range from 1 through 10 (1 being the lowest setting and 10 being the highest). The procedure will determine the tip selected and power level used. Refer to the table located on Page 11, “Power Settings & Use of KLAW™ Tips”, for recommended power settings.
Note: If power range exceeds recommended settings below, this may cause tip breakage.
To disconnect the handpiece from the cord, hold the handpiece by the purple ring in one hand and the cord coupler in the other hand, then pull apart (See Figures 10.3 and 10.4). Do not pull on the cord! Doing so will void the warranty. After disconnecting the handpiece, it is recommended to use the Air / Water Syringe to blow any left over water from the connector (See Figure 10.5). Water or fluid left in the cord coupler may render the unit inoperative for future use.
Disconnect the Handpiece
Piezo Care & Maintenance
Disconnect the LED Piezoelectric Handpiece from the cord and clean the handpiece with a disinfectant (non-chloride, non-iodine). Do not spray the handpiece with disinfectant while attached to the cord. Do not immerse in any solution, including ultrasonic or cold sterile solutions, as this will damage the handpiece and void the warranty. Dry handpiece with a clean cloth or gauze square. Place handpiece in a sterilization bag or autoclavable box and autoclave for 3 minutes at a maximum of 275° F / 135° C. (Ensure KLAW™ tip has been removed from the handpiece prior to autoclaving. Failure to separate the tip from the handpiece will cause the tip to fuse to the handpiece). Additional handpieces may be purchased to accommodate autoclave turnaround time.
Note: The use of a rapid heat sterilizer is not recommended.

KLAW™ Tip Installation
The HS4W LED Dental Cart includes three KLAW™ tips; KLAW™ 1, KLAW™ 4 and KLAW™ 6. To install a tip on the handpiece; hold the handpiece in one hand, place the KLAW™ tip on the end of the threaded shaft and then rotate the tip to the right until it is finger tight. The tip wrench must be used to tighten the KLAW™ until snug to assure proper operation of the scaler (See Figure 11.1).
Note:Do not over tighten KLAW™ tip; this may cause breakage of the handpiece stud.
KLAW™ Tip Technique
It is very important to use a feather light touch with the tips. Too much pressure can cause damage to the KLAW™ as well as the patient’s teeth. The KLAW™ tip and the LED Piezoelectric scaler will do the work; it is not necessary to apply pressure or push down. You will get optimal results by simply using a light paint brush stroke with the side of the tip, gently guiding the handpiece and tip, using the same pressure as if writing with a pencil or similar to periodontal probing.
