3Warnings
This product is intended only for use by trained dental pro-
fessionals. Read the operating instructions carefully prior to
start-up of the Contra-Angle handpiece and keep for future
reference.
Observe all safety information and warnings, including the
following:
•The Contra-Angle must be sterilized prior to first use.
•The Contra-Angle handpiece should be sterilized after
each patient to prevent any transmission of infective agents
such as e.g. HIV (the AIDS virus) or hepatitis B which might
cause serious illnesses or even lead to death.
•Suitable hygienic measures must be taken to prevent cross
contamination among patients, users and other persons.
•Use the Contra-Angle handpiece only when the endodontic
instrument is clamped securely in place. Do not pull the
endodontic instrument out of the Contra-Angle handpiece
head. A loose or partially removed endodontic instrument
could detach itself from the head or break off and cause in-
juries.
• After sterilization:
Immediately remove the Contra-Angle handpiece from the
steam sterilizer.
•Sterilize again once the storage period has elapsed accord-
ing to the manufacturer of the sterilization container.
• Prior to each use, test whether the fitted instrument is firm-
ly seated by pulling and turning it.

62 39 920 D 3451 7
ATTENTION! Make sure not to inadvertently press the
pushbutton when pulling back the patient's cheek with the
Contra-Angle handpiece while the motor is running. Doing
so will risk burning the oral mucosa!
•If the contra-angle handpiece is defective, the area around
the instrument head may heat up, thus creating a risk of burn-
ing the patient's oral mucosa.
•Do not repair the Contra-Angle handpiece yourself. Contact
the Technical Service Department at 1-800-662-1202 for
any repairs.
•Attach or remove instruments from the Contra-Angle only
when the motor is off.
•Do not use bent, damaged or deformed endodontic instru-
ments. Worn instruments can result in injury.
•Use only instruments whose shanks comply with the re-
quirements of DIN EN ISO 1797-1.
•Do not immerse the Contra-Angle handpieces in cold water
to speed up the cooling process. This would permanently
damage your Contra-Angle handpiece!
•Do not leave any Contra-Angle handpieces on the motor
overnight, in order to prevent oil from penetrating into the
electric motor. Never lubricate the electric motor!
