6.2 Installation notes
HATZ diesel engines are efficient, robust and have a long service life. Therefore, they are usually installed in machines that are used for commercial purposes.
The machine manufacturer must follow the applicable regulations regarding
machine safety – the engine is a part of a machine.
Depending on the use and installation of the engine, it may be necessary for
the machine manufacturer and machine user to install safety equipment to
prevent inappropriate use. Note the following:
▪ Parts of the exhaust gas system and the engine surface become hot dur-
ing operation and may not be touched until they cool down after the engine is switched off.
▪ Incorrect cable connections and incorrect operation of the electrical equip-
ment can lead to sparking and must be avoided.
▪ After the engine is installed in the machine, rotating parts must be pro-
tected against contact.
HATZ safety equipment is available for the belt drive of the cooling fan and
alternator.
▪ Comply with all notices and warning labels on the engine and keep them
in a legible condition. If a label should become detached or be difficult to
read, it must be replaced promptly. For this purpose, contact your nearest
HATZ service station.
▪ Any improper modification of the engine results in a loss of liability cover-
age for resulting damage.
Only regular maintenance, as specified in this Operators Manual, will maintain the operating readiness of the engine.
The assembly instructions contain important information on how to safely
assemble the engine. They are available from any Hatz service station.
If you have any questions, please contact your nearest HATZ service sta-
tion before commissioning the engine.
