Opel 1900 1973, Service Manual, Page: 2 / 625

IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all motor vehicles.
The service procedures recommended by BUICK and described in this service manual are
effective methods for performing service operations. Some of these service operations
require the use of tools specially designed for the purpose. The special tools should be used
when and as recommended.
It is important to note that some warnings against the use of specific service methods that
can damage the vehicle or render it unsafe are stated in this service manual. It is also
important to understand these warnings are not exhaustive. BUICK could not possibly
know, evaluate and advise the service trade of all conceivable ways in which service might be
or of the possible hazardous consequences of each way. Consequently, BUICK has
undertaken any such broad evaluation. Accordingly, anyone who uses a service procedure
which is not recommended by BUICK must first satisfy himself thoroughly that neither
his safety nor vehicle safety will be jeopardized by the service method he selects.
