This symbol identifies important safety precautions.
Please comply with these most carefully in order to avoid any risk of injury to persons or
damage to materials.
General legal requirements and safety regulations issued by the competent authorities or
industrial accident insurers must also be complied with.

1. Important notes on safe operation of the engine
HATZ diesel engines are economical, stronly built and long-lasting. They are therefore frequently
chosen for commercially and industrially operated equipment and machinery.
Since the engine forms part of the finished equipment or machine, its manufacturer will take all the
applicable safety regulations into account.
Nevertheless, we give below certain additional comments on operating safety, and would recommend
you to note them carefully.
Depend on the manner in which the engine is installed and its intended application, the equipment
manufacturer or operator may have to attach additional safety devices and prohibit potentially
hazardous aspects of operation, for example:
– Exhaust system components as well as the surface of the engine will naturally be hot and must not
be touched while the engine is running or until it has cooled down after being stopped.
– Faulty wiring or incorrect operation of electrical equipment may lead to sparks forming, and must
be avoided as a potential fire hazard.
– Rotating parts must be shielded against accidental contact when the engine is installed in other
equipment or machinery.
Guards are available from HATZ to protect belt drives to cooling fans and generators.
– Before attempting to start the engine it is essential to have studied the starting information in the
instruction book.
– Mechanical starting devices must not be used by children or persons of insufficient physical
strength.
– Before starting the engine, ensure that all the specified protective guards are in place.
– The engine must only be operated, serviced or repaired by persons who have received the
appropriate trainig.
– Keep the ignition key out of reach of unauthorized persons.
– Do not run the engine in closed or badly ventilated rooms.
Do not breath in emissions – danger of poisoning!
– Also fuel and lubricants could contain poisonous components. Please follow the instructions of the
mineral oil producer (safety data sheets).

Important notes on safe operation of the engine
– Stop the engine before performing any maintenance, cleaning- or repair work.
– Stop the engine before refuelling.
Never add fuel near a naked flame or a source of sparks.
Don't smoke. Don't spill fuel.
– Keep explosive materials as well as flammable materials away from the engine because the exhaust
gets very hot during operation.
– Wear close-fitting clothing when working on a running engine.
Please don't wear necklaces, bracelets or any other things which you could get caught with.
– Please pay attention to all advice- and warning stickers placed on the engine and keep them in legi-
ble condition. In case a label has come off or is no longer clearly legible, it must be replaced imme-
diately. To this effect, please contact the HATZ service station in your area.
– Note that any unauthorized modification to the engine absolves its manufacturer from liability for
the consequences.
Regular servicing in accordance with the details provided in this Instruction Book is essential to keep
the operating reliably and to ensure the exhaust quality of the engine.
In case of doubt, always consult your nearest HATZ service station before starting the engine.

Never use starting aids in the form of
aerosols or sprays !
4.2.2. Electric starter
– For starting preparations, see Chapter 4.2.1.
12
– Insert the start key to its stop and turn it to
position I.
Battery charge telltale „2“ and oil pressure
warning light „3“ will come on.
– Turn start key to position II
– As soon as the engine runs, release the start
key. It must return to position I by itself and
remain in this position during operation.
The battery charge telltale and oil pressure
warning must go out immediately after start-
ing. Indicator light „1“ is on when the engine
is in operation.
– The engine temperature display „4“ (additional
equipment) lights up if the temperature at the
cylinder head becomes too high.
Switch off the engine and trace and elimi-
nate the cause of the problem, chapter 7.
– The air cleaner maintenance indicator „5“
(additional equipment) only lights up during
operation if the air cleaner element needs to
be cleaned or renewed (chapter 5.4.2.).
– Always turn the start key back to position 0
before re-starting the engine. The repeat lock
in the ignition lock prevents the starter motor
from engaging and possibly being damaged
while the engine is still running.
Important !
If a starter protection module is fitted, the key
must be turned back to position 0 for at least
8 seconds if the engine fails to start, before a
second attempt of starting can be made.
Note:
Start for max. 30 seconds. If the engine does
not run after this time, turn starter key back to
position 0 and eliminate the cause, Chapter 7.
12

Preheating device with automatic heating
timer (additional equipment)
The preheating light „6“ lights up additionally at
temperatures below 0° Celsius (Fig. 12).
– After the light has gone out, start the engine
without delay.
Automatic shut-down function
(additional equipment)
This is characterized by a brief flashing of all
pilot lamps once the starter key has been turned
to position I (Fig. 12).
Important !
If the engine cuts out immediately after starting
or switches off by itself during operation, a mon-
itoring element in the automatic shutdown sys-
tem has tripped. The corresponding indicator
light (Fig. 12, positions 2 - 4) will come on. After
the engine has stopped, the display continues to
glow for about 2 minutes.
The electrical device then switches itself off au-
tomatically.
The display lights up again after the start key
has been turned back to position 0 and then to
position I again.
Trace and eliminate the cause of the
operating fault before trying to restart the
engine (see chapter 7).
The display light goes out when the engine is
next started.
Even with automatic shutdown monitoring the
oil level must be checked every 8 –15 operat-
ing hours (chapter 5.2.1.).
4.3. Engine use
Engines certified for constant or variable speed
within a certain operating range, must be operat-
ed according to the operator’s manual of the ma-
chine. Any changes in the speed adjustment sys-
tem are forbidden by law.
13

4.4. Stopping the engine
13
– Move speed control lever „1“ back to the
„STOP“ position.
– On engines with the lower idling speed out of
use, move speed control lever „1“ back, then
