source without a purge cycle. The scaler air line will bleed off to

zero pressure protecting the AUTOSCALER®.

3. Plug the power cord into the wall (see electrical requirements).

4. Select an insert. Moisten the rubber O-RING before inserting into

the handpiece. While holding the handpiece, UPRIGHT, place the

insert in the open end of the handpiece, and with a gentle PRESS

and TURN motion, snap the insert in fully. DO NOT force the insert.

5. Manufacturer recommends the use of a disposable handpiece

sleeve/barrier be used over the handpiece assembly. Place the

sleeve/barrier over the handpiece. While holding the sleeve/

barrier in place, puncture the insert through the plastic at the

open end of the handpiece, and snap the insert in fully. Dispose of

sleeve/barrier after each patient.

6. Due to atmospheric exposure, and exposure to sterilization

solutions, the O-RING on the insert tip may become swollen,

brittle, or crack, and require replacement.

7. Set the POWER KNOB all the way to the LEFT in the LOW position

8. Hold the handpiece in a VERTICAL upright position, and step on

the foot switch. Within 10-15 seconds water should come out of

the open end of the handpiece IF NOT, QUICKLY

turn WATER KNOB clockwise 1-2 rotations to get

water flow. Some air will escape at the same

time. This step is IMPORTANT because trapped

air will cause HOT SPOTS (usually noted by a

loud screeching sound) which can affect the

performance of the AUTOSCALER® or

permanently damage the handpiece assembly.

9. Inserts and handpiece will burn in 45-60 seconds in the absence

of water. A (18cc—30cc/+/min) flow is the normal flow range, and

necessary at all times. NEVER touch the Cavitating/Vibrating end

of the insert tip to any flesh such as the cheek, tongue, or gums

unless performing special periodontal procedures. This will cause a

FRICTION BURN to the patient. Always keep the insert in motion.

Do not rest the handle or insert on the lips during a procedure.

The insert tip should touch primarily the calculus on the tooth

surface, and NOT the enamel of the tooth surface.

10. Allow the air bubbles to escape for about 10-20 seconds. Turn the

POWER KNOB to the RIGHT in the Medium position, and the

insert tip should Cavitate/Vibrate with a strong mist. Turn the

water knob to the right if there is no mist or weak misting.

11. The application of the power knob is for controlling the Output

Power to the insert tip in a smooth linear action. The operator can

select the EXACT power needed for cleaning. Set power knob LOW

(Left Direction) to MEDIUM (Center) for cooler handpiece/insert

temperature.

12. The high power setting is for applications where an excessive

amount of calculus is built up. The Low power setting can be used

for periodontal Subgingival curettage and root planing

procedures. Most scaling should be done only on the LOW to

MEDIUM power setting.

13. If SLIMLINE™, FSI™ or Modified Periodontal inserts are used, set

the POWER Knob in the BLUE shaded area. This power level is

designed to be used with these fragile specialty inserts. Inserts

may give a drip and mist combination, this is normal for these

inserts. This is actually preferred by most Periodontal

professionals due to the water drip being ultrasonically activated

within 0.5mm of the tip assisting in killing plaque.

SHUT DOWN PROCEDURE

Be sure to shut off Air and Water supply to the scaler when

unattended. The installing service technician will indicate to the

operator which controls perform this action.

TROUBLESHOOTING

If the unit does not function, proceed with the following:

1. Check the plug. Is it all the way in the receptacle?

2. Try another insert. Make sure it is the correct frequency 25K or

30K depending on your model. Each model has a frequency (25K or

30K) label on the cover and the frequency is also indicated on the

serial number plate located on the bottom of the device. The most

common mistake when purchasing a new unit is selecting the

wrong frequency insert.

3. If water flow is insufficient, check water pressure at the operatory for

minimum of 20 P.S.I. The Insert Water slot could be clogged with

debris. Try another insert.

4. If the handpiece handle or insert operates HOT: REDUCE POWER

LEVEL and INCREASE WATER FLOW. Depending on the water

regulator supplied in your operatory the following applies: HIGHER

water flow to the RIGHT, and LOWER water flow to the LEFT. Some

water regulators adjust the opposite (more flow to left and less to the
