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.
