Troubleshooting - parkell Integra D680 Manual

1) Disconnect the scaler from the
water supply.
2) Remove the old fi lter disk by holding it
in one hand and twisting off the hose
connectors on either side. (They rotate in
opposite directions.)
3) Install the replacement fi lter disk, and
fi rmly tighten the connectors using
hand pressure.
4) Reconnect the scaler to the water supply
and check for leaks.
(Note: If the fi lter becomes clogged
and you do not have a replacement disk,
the hose connectors can be locked
together without the fi lter disk to allow
emergency operation.)
If you have any questions, please contact
Parkell Service Dept. at (1-800-243-7446).

General comments on scaling:
Ultrasonic scalers should be used only by
■
trained, licensed professionals.
Inserts and the handpiece sheath should be
■
sterilized before each use.
Do not operate unit without water fl owing.
■
Use of face mask is recommended when
■
operating this device, to avoid inhalation
of contaminated aerosol by the operator.
High-volume suction to remove this
aerosol from the dental environment (as
close to the source as possible) is also
recommended.
Use the lowest effective scaling power
■
for the case at hand. This keeps heat
generation to a minimum.
Before using the insert in the oral cavity,
■
adjust the water spray over sink or
cuspidor until desired mist is obtained. For
maximum patient comfort, use a good fl ow
of water which acts as coolant, lubricant
and lavage to fl ush out debris.
If patient is new to ultrasonic scaling,
■
tell him/her what to expect. If procedure
becomes uncomfortable, adjust power and
water controls accordingly.
Grasp handpiece in a comfortable manner,
■
like holding a pen. To remove deposits
from teeth, always use a light brushing
stroke with the side of the insert tip in
contact with the tooth surface. Excess
pressure will not improve scaling action,
but may cause heating and pain to the
patient. Keep the scaler insert in motion at
all times and use repeated gentle strokes to
remove all tenacious deposits.
Exercise caution near porcelain and resin
■
restorations as they can fracture.
Occasionally turn unit off to evaluate
■
deposit removal with an explorer.
If you test any scaler tip on your fi ngers
■
while operating, it will feel uncomfortably
hot. This is not a true test of how it feels
on a tooth. To operate, adjust the power
control to the minimum setting for the case
at hand (start at zero). With a good water
fl ow, the patient will not experience any
uncomfortable heat.
Common operator errors:
Failure to keep insert tip parallel with the
■
long axis of the tooth surface.
Excessive use of hand pressure.
■
Failure to use the lowest effective power
■
setting for the case at hand.
Insuffi cient water fl ow.
■
Scaling with the point of the insert instead
■
of the side.
These failures in procedure can result in
ineffective or incomplete removal of
deposits and possible damage to the pulp or
tooth structure.
