6.2 Troubleshooting
WARNING
Repair WITHOUT using KaVo original spare parts.
Parts could come loose and cause injury. Aspiration, swallowing of parts and
danger of suffocation.
4
Only use spare parts that comply with the specification for repair; original
KaVo spare parts comply with the specification.
NOTE
If a repair is done with NON-KaVo original spare parts, this may constitute a
product modification that leads to the loss of CE conformity. In the event of
damage, the responsibility is with the service company or the operator.
The introduction of a modified product in the market, in which the reasonable
suspicion exists to endanger the safety and health of patients or users, is pro-
hibited by MPG (in English medical device law) §4, section 1 No. 1 and there-
fore requires its own conformity check.

Do not use Vaseline or other grease or oil.
4
