Foreword

This Workshop Manual covers the latest technical developments according to

month/year indicated on each page. It has been written in such a way, that it contains all

dismantling and assembly instructions in accordance with the table of contents, includ-

ing all required data etc., so as to permit a trained mechanic to carry out correct and

professional repairs.

We have not included information such as cleaning parts, replacing of "O" Rings, gas-

kets, oil seals etc. since it is assumed, of course, that the mechanic will be aware of the

necessity of carrying out such work.

Use only the tools prescribed or absolutely identical tools when carrying out work of

whatever nature.

It has been assumed that a standard set of workshop tools is available.

Please refer to the instruction book for maintenance work, operating materials and trou-

ble shooting information.

Use only GENUINE HATZ PARTS for repairs!

Only these parts guarantee perfect dimensional accuracy and quality.

For the rest, please observe the general legal regulations and the regulations of the re-

sponsible professional associations.

Discrepancies may occur between the described features and actual features owing to

special equipment, and it has not been possible to allow for such discrepancies either in

the Workshop Manual or in the spare parts list.

Should you have any difficulties, please contact your nearest HATZ-Service agent.
