INTRODUCTION
This manual is designed to give dealers and their staff all
guidance and information necessary to enable them to pro-
vide and efficient repair and maintenance service, but it is in
no way intended as a substitute
for the practical and theo-
retical training available to personneI at our Service Training
School.
It will be found useful as a ready reference in day-to-day
workshop practice.
Gur illustrated Spare Parts List, which shows the various
components in detail, will also be found helpful when used in
conjunction with
this booklet.
Naturally , good maintenance and repair work and efficient
servicing call for good equipment, a we ll-equipped workshop
and skilied personnel.
Dealers are requested to make this manual and all
SACHS
Service Bulletins, which contain technical modifications ,
available to every individual responsible for actual servicing .
The proper place for this kind of technical infor-
matio l1' , is in the workshop and not in the filing
cabinet.
We hope that this manual will be of real practical assistance
to all
our dealers, agents and associates.
