• Heating of handpieces during operation must be avoided, as it could cause injury to the patient. Prior to a day’s use,
run the handpiece on the motor for one minute and check for heating, vibration or unusual noise. Heating could be caused by
debris caught in the bearings in the head, accumulation of debris where the heating occurs, or lack of lubrication. Place a bur in the
handpiece and rotate gently with the fingers. If the bur is resistant, feels sandy or grinding, spray oil into the handpiece a few times
or until the resistance stops.
• Do not use long surgical bur on speed increasing handpiece. Do not use burs longer than 26 mm. Its shank may warp under load at a
high speed and spin-out or lead to premature bearing failure.
• Entering foreign object into gear or inside of handpiece head may cause burn injury.
• Wear protective glasses and mask during use.
• Depressing the push-button while the handpiece bur is in rotation will result in OVERHEATING of the handpiece head.
Special caution must be exercised during use to keep the cheek tissue AWAY from the push-button of the handpiece.
Contact with cheek tissue may cause the push-button to depress and an injury to the patient may occur.
• Even with irrigation, if the bearing is worn, the handpiece may overheat or vibrate loudly. If this occurs, contact Brasseler USA for a
repair on the handpiece.
