5.1
System set-up
Connecting the accessories Combinations of accessories that are not mentioned in the present instructions for use may only be employed if they are specifically intended for the respective application, and if they do not compromise the performance and safety characteristics of the products. ► Please address your B. Braun/Aesculap partner or Aesculap Technical Service with any inquiries in this respect; for a contact address, see Technical Service.
Coupling/uncoupling the handpiece to/from the drive unit ► Couple the connection of the respective drive unit directly to the saw handpiece 4. To this end, push the hand-
piece 4 onto the centering lug of the corresponding drive unit until it touches the cover plate and clicks into position. ► To release, activate the corresponding unlocking device and pull out the handpiece 4.
Damage to the motor unit from incorrect coupling of the saw! ► Couple the micro sagittal saw with the motor unit only while the motor is inactive. CAUTION ► Operate the saw handpiece with a reduced rotational speed when setting the saw cut. ► Increase the rotational speed to approx. 20 000 1/min if the saw blade is guided.
Note The best cutting performance is achieved at 20 000 1/min and with simultaneous, straightforward overlay of the saw blade stroke with the handpiece for supporting the chip removal. ► Small fragments and very fine bone structures may require additional fixing in order to avoid vibration.
Coupling a motor unit ► Coupling is carried out by sliding the micro compass saw with Intra coupling 5 onto centering lug of the drive
until it touches cover plate and clicks into position.
Uncoupling the motor unit ► Activate the unlocking button on the drive and withdraw the micro sagittal saw.

General information
Dried or affixed surgical residues can make cleaning more difficult or ineffective and lead to corrosion. Therefore the time interval between application and processing should not exceed 6 h; also, neither fixating pre-cleaning temperatures >45 °C nor fixating disinfecting agents (active ingredient: aldehydes/alcohols) should be used. Excessive measures of neutralizing agents or basic cleaners may result in a chemical attack and/or to fading and the laser marking becoming unreadable visually or by machine for stainless steel. Residues containing chlorine or chlorides e.g. in surgical residues, medicines, saline solutions and in the service water used for cleaning, disinfection and sterilization will cause corrosion damage (pitting, stress corrosion) and result in the destruction of stainless steel products. These must be removed by rinsing thoroughly with demineralized water and then drying. Additional drying, if necessary. Only process chemicals that have been tested and approved (e.g. VAH or FDA approval or CE mark) and which are compatible with the product’s materials according to the chemical manufacturers’ recommendations may be used for processing the product. All the chemical manufacturer's application specifications must be strictly observed. Failure to do so can result in the following problems: ■ Optical changes of materials, e.g. fading or discoloration of titanium or aluminum. For aluminum, the application/process solution only needs to be of pH >8 to cause visible surface changes. ■ Material damage such as corrosion, cracks, fracturing, premature aging or swelling. ► Do not use metal cleaning brushes or other abrasives that would damage the product surfaces and could cause corrosion. ► Further detailed advice on hygienically safe and material-/value-preserving reprocessing can be found at www.ak-i.org, link to Publications, Red Brochure – Proper maintenance of instruments.
