Manufacturer’s liability

We expressly point out that we can accept responsibility for any effects
on the safety, reliability, and performance of our medical products, if and
only if:

• any assembly, extensions, readjustments, modifications, or repairs are
performed by technically experienced, knowledgeable and trained
personnel and

• the medical products are used as set forth in the instructions for use.

It is possible to learn to service the products through an appropriate
course of instruction given on the premises of Aesculap about the r elevant
medical products. To arrange for such a course, contact Aesculap
Technical Service (ATS).

To ensure that your Aesculap warranty remains valid, we recommend that
only spare parts that have been factory tested by Aesculap be used for
repairs. Spare parts, as well as the relevant tools, can be ordered from
Aesculap Technical Service (ATS). Any unauthorized opening and/or
alterations of the medical product by third parties lead to the exclusion of
our liability, as far as a fault is attributable to such unauthorized opening
and/or alteration of the product. Aesculap cannot accept responsibility for
the use of unsuitable spare parts, tools or devices. After repairs, dropping,
severe damage or misuse, the product should be inspected by a qualified
person.

This manual refers to the product as it was when the manual was
prepared. Technical changes may be made at any time, particularly in
software.

General advisory

This service manual contains illustrations and explanations. Each
explanation covers the following: modes of operation, spare parts list,
assembly, disassembly, functionality test, and the section tools/devices (if
applicable).

For further information about a specific product (e.g. troubleshooting list,
accessories) consult the relevant user instructions.

Literature Art. no.

Instructions for use TA005834

It is crucial that extreme cleanliness be maintained when the products
described below are repaired. All products must undergo a functionality
test after being repaired. If, in the course of a repair, a labeled component
is replaced, the labeling must be transferred to the spare part. Either the
original label should be used or the spare part bearing the relevant label
should be ordered. To this end, be sure to include the applicable
information when ordering.

Unless otherwise indicated, all medical products should be inspected
annually.

General information about motors and handpieces

It is critically important that ball bearings be inspected annually. Even the
slightest defect or soiling can lead to overheating during use, which would
render the product unusable. If for the repair of, e.g., a motor a ball
bearing has to be replaced, it is best in most cases to replace all other ball
bearings as well.

If it is necessa ry to heat up adhes ive joints during disassembly, a hot-air
blower is the appropriate tool. The smallest possible nozzle should be used
so as to avoid damaging other components. When gluing parts together,
make certain that the surfaces to be joined are absolutely clean and fr ee
of grease. We recommend using Loctite Rapid Cleaner 7063 for this
purpose (WS. no. 520001750). Only u se adhesives listed in this manual.
Follow the glue manufacturer’s recommendations.

Lubricate components with the recommended Aesculap product only.
Following disassembly, clean all components thoroughly and inspect them

to ensure that they are undamaged. Do not install any component of
whose status you are uncertain. Products must always be test-run for
several minutes after being repaired.
