Important
The device must not be started with-

tating motor.
To ensure your CA micromotor is op-
erating correctly, we recommend a
cooling air flow of 7 to 9 standard
litres/min.

dance with ISO 6360/1. In endodon-

Maintenance

Important
• The instrument is delivered
"non sterile".
• Before using for the first time and
within a maximum of 30 min-
utes after each treatment, clean,
disinfect and lubricate the instru-
ment, then sterilise. Observing
this procedure eliminates any
blood, saliva or saline solution
residues and prevents the trans-
mission system from being
blocked.
• Only instruments bearing a pic-
togram can be placed in the
washer/disinfectant unit.
• Do not immerse in an ultra-
sonic bath.
• Only use original Bien-Air Dental
maintenance products and parts
or those recommended by Bien-
Air Dental. Using other products
or parts may cause operational
failure and/or void the guarantee.
