THE AUTOSCALER DIRECTIONS FOR USE Rev: A March 16, 2007
RESTRICTOR FITTING. The restrictor relieves the air input line if
accidentally charged from another air source without a purge cycle.
The scaler air line will bleed off to zero pressure protecting THE
AUTOSCALER.
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. (NOTE): Inserts and handpiece will BURN OUT 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 REASON for this is due to the 25,000 or
30,000 back and forth strokes of the insert every second. This is
the principal idea of ultrasonic cleaning activity. The insert tip should
touch PRIMARILY the calculus on the tooth surface, and NOT the
enamel of the tooth surface.
10. 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.
11. (NOTE): Manufacturer recommends disposable handpiece sheathes
be used over the handpiece assembly.Place the sheathe over the
handpiece. While holding the sheathe in place, puncture the INSERT
through the plastic at the open end of the handpiece, and snap the
insert in fully according to STEP F. Dispose sheathe after each
patient.
