1. Important notes on safe operation of the engine
HATZ diesel engines are economical, strongly 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.
Depending 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 hazard-
ous aspects of operation, for example:
– Parts of the exhaust system as well as the surface of the engine are of course hot during operation
of the engine, but also when it is still cooling down after use, and must not be touched.
– 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, cooling fans and generators.
– Before attempting to start the engine it is essential to have studied the starting information in the
Instruction Book; this is particularly important on engines started with a starting handle.
– Mechanical starting devices must not be used by children or persons of insufficient physical
strength.
– In order to benefit from the advantages of the starting handle with kick-back damping, it must be
used precisely as recommended in this Instruction Book.
– 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 appro-
priate training.
– Keep the starting handle and the key out of reach of unauthorized persons.
– Never 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- and 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.

as standard equipment, so that the en-
gine can be lifted safely. It is not suitable for
lifting complete machines or similar with the
engine attached, and this is strictly prohibited.
(See Chapter 2.)
3.3. Instructions for installation
If you have an engine which is not yet installed
in a machine and still has to be installed, make
sure that the Assembly Instructions for HATZ
Diesel Engines are complied with prior to instal-
lation. These Assembly Instructions contain im-
portant information about safe assembly of the
engine and are available from your the HATZ
service center in your area.
Pending complete installation, the engine
must not be started !
Moreover, we would like to point out that in this
case, commissioning of the machine is also pro-
hibited until it has been verified that the machine
into which this engine is to be incorporated
complies with all the safety precautions and reg-
ulations provided by law.
Refer also to the Declaration for Incorporation
at the end of these Operating Instructions.

➆rated power
➇emission control system information (see
page 42 and 58)
➈“variable speed” or “constant speed only”
(if requested)
The type plate also states the applicable emis-
sion-related power category of the engine.
The figure of the lable shows a EPA/CARB (50
states) label. The text referring to the emission
regulation gets printed depending on the engine
equipment (EPA or EPA and CARB).
Every engine is equipped with an additional
loose engine type plate. If the original type
plate on the engine is not readily visible after
the engine is installed in the equipment then
the second loose type plate must be attached
on the equipment in such a manner that it is
readily visible to an average person.
For any offer as well as spare parts orders it is
necessary to mention the following data (also
see spare parts list, page 1):
➁engine type / spec.

oil.
4.1.1. Engine oil
Qualified are all trademark oils which fulfil at
least one of the following specifications:
ACEA – B2 / E2 or more significant
API – CD / CE / CF / CF-4 / CG-4 or more
significant.
If engine oil of a poorer quality is used, reduce
oil change intervals to 150 hours of operation.
Oil viscosity
5
Please select the recommended viscosity de-
pending on the ambient temperature at which
the engine is operated.
Inappropriate engine oil may shorten the
engine’s service life significantly.
The engine must be in a horizontal position be-
fore adding oil or checking the oil level.
6
– Pull out dipstick „1“ and add engine oil of the
correct specification and viscosity up to the
„max“ mark on the dipstick; (Chapter 3.1.).
4.1.2. Oil bath air cleaner

4.1.3. Fuel
Only refuel when engine is stopped.
Never refuel close to open flames or
flammable sparks, don’t smoke. Use only pure
fuel and clean replenishing cups. Don’t spill
the fuel.
All diesel fuels sold as fuel and complying with
the following minimum specification can be
used:
EN 590 or
BS 2869 A1 / A2 or
ASTM D 975 - 1D / 2D
Important !
The use of fuels of different specifications re-
quires the prior written consent of the HATZ
headquarters.
8
– Before the first start or if the fuel tank has
been run dry, completely fill the fuel tank with
diesel.
The fuel system is bled automatically if the fuel
tank is attached to the engine or located higher
than the injection pump.
9
– If the fuel tank is not mounted on top of the
engine, or is at a lower level, operate the lever
on the fuel feed pump until fuel is heard to
flow back to the tank through the return line.
10
– On fully encapsulated engines, move sleeve
„1“ to one side to gain access to the feed
pump.
After operating the feed pump, make sure that
the sleeve is replaced correctly and makes a
good seal.

At temperatures below 0 °C, winter-grade fuel
should be used or parafin added to the fuel well
in advance.
4.1.4. Mechanical oil pressure
monitor (optional extra)
The mechanical oil pressure monitor should be
activated:
•when first filling, or after running the fuel tank
dry.
• if engine shut down automatically because lu-
bricating oil supply was inadequate.
• after freeing it by turning at low temperatures
(Chapter 4.2.4.)
• after replacing the fuel filter, Chapter 5.4.1.
– Add fuel, chap. 4.1.3.
– Check engine oil level, chap. 5.2.1.
11
– To activate the monitor, press lever „1“ for
approx. 15 seconds.
12
– If the engine has a full capsule, press pin „1“
for app. 15 seconds.
– If the engine has a fuel feed pump, operate its
lever for several strokes at the same time
(Figs. 9 and 10).
– Re-assemble all parts repositioned or re-
moved. Check that capsule elements make a
good seal.

IMPORTANT !
Even with mechanical oil pressure monitoring
the oil level must be checked every 8 – 15
operating hours (Chapter 5.2.1.).
4.2. Starting the engine
Do not run the engine in closed or
badly ventilated rooms – danger of
poisoning ! Before the engine is started, al-
ways make sure that nobody is in the danger
area (moving parts on engine or machinery)
and that all safety guards are in place.
Check that the starting handle is in good condi-
tion: renew tubular grip if broken, worn drive pin
etc.
Lightly grease the sliding-contact area between
the starting handle and the guide sleeve.
14
Risk of serious injury from rotating parts.
Never put your hands in the guide sleeve of the
cranking device while the engine is running.

4.2.1. Preparations for starting
– If possible, disengage the engine from any
driven equipment. The auxiliary equipment
should always be placed in neutral.
16
– Set speed control lever „1“ to a position be-
tween 1/2 START and max. START, according
to requirements. Selecting a lower engine
speed will reduce smoke when starting.
– Make sure that stop lever „2“ - if fitted - is in
the operating „START“ position.
17
18
– Turn the decompression lever until stop „1“ is
reached. In this position the automatic decom-
pression system is heard to engage and the
engine can then be started; Figs. 17 and 18.
19
After the automatic decompression device has
engaged at its limit stop, five turns of the crank
handle are needed for the engine to build up
compression and fire again.

4.2.2. Starting with the handle
For preparations to start the engine,
see Chapter 4.2.1.
20
For correct position to adopt when starting the
engine, see Fig. 20.
Starting with the handle with kick-back
damping (retrofit)
21
– Always hold tubular grip „1“ with both hands.
– Turn the handle slowly until the pawl engages
in the ratchet, then increase turning force to
build up speed. The highest speed must have
been reached when the decompression lever
returns to the „0“ position (compression). As
soon as the engine has started, pull the start-
ing handle out of the guide sleeve.
You must hold the tubular grip firmly to
maintain contact all the time between
the starting handle and the engine. Maintain
turning force during the entire hand starting
operation.
If backfiring occurs when starting the engine be-
cause the crank handle was not turned firmly
enough, the brief reverse rotation at the handle
tube separates the link between crank lug „2“
and driving dog „3“ (Fig. 21).
– If the engine begins to run backwards after
backfiring (smoke emerges from air cleaner),
release the crank handle immediately and stop
the engine (Chapter 4.3.).
– To restart the engine, wait until it has come to
a standstill, then repeat the starting prepara-
tions.
Starting by means of the standard
starting crank
In the countries of the European Union,
starting cranks without kick-back dam-
ping must not be used.
For preparations to start the engine,
see Chapter 4.2.1.
– For correct position to adopt when starting the
engine, see Fig. 20.
3
2 1
2395 / 4
15

– Take hold of the starting handle with both
hands and turn it at increasing speed. The
maximum speed of rotation must have been
reached by the time the decompression lever
has returned to the „0“ position (compres-
sion). As soon as the engine has started, pull
the starting handle out of the guide sleeve.
– If the engine backfires because the crank han-
dle was not turned firmly enough (the engine
may even start to run backwards), release the
crank handle immediately and stop the engine
(Chapter 4.3.).
There is a risk of injury from the
rotating crank handle.
– To restart the engine, wait until it has come to
a standstill, then repeat the starting prepara-
tions.
Safety precaution
For greater protection against accidental injury
when starting with the handle, a handle with
kick-back damping can be used.
4.2.3. Starting in cold weather
At temperatures below app. –5 °C, always turn
the engine over to ensure that it rotates freely.
– Move the speed control lever to the START
position; Fig. 16.
– Place decompression lever in central position
between „0“ and „1“ (Fig. 17 and 18).
– Turn the engine over with the starting handle
until it is felt to rotate more freely (10 – 20
turns of the starting handle).
– If mechanical oil pressure monitoring is
fitted, press lever „1“ or pin „1“ in for about
15 seconds (Figs. 11 and 12).
22
23
– Remove dirt from the cover of the metering
device and the surrounding area. Pull off the
cover; Figs. 22 and 23.
– Add a free-flowing lubricating oil to the
housing until the level reaches the upper rim.
Replace the cover and press it in firmly. Two
filling operations in succession are needed.
– Turn the decompression lever until
limit stop „1“ (fig. 17 and 18).
– After this, start the engine immediately.

4.2.4. Electric starter
For preparations to start, see Chapter 4.2.1.
– The decompression lever remains in pos. „0“.
Starting procedure
24
– Insert the key to its stop and turn it to
position I.
– Battery charge telltale „2“ and oil pressure
warning „3“ must light up.
– Turn start key to position II (fig. 24).
– 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.
– If anything seems to be incorrect, stop the en-
gine immediately and trace and rectify the fault
(chapt. 6).
– 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, chap. 6.
– 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.
Never operate the electric starter when
the engine is running or coasting to a
standstill. There is a risk of broken starter pin-
ion or ring gear teeth.
Important:
If a start protection module is installed, the start
key has to be returned to position 0 for at least
8 seconds if the engine has failed to start before
a further attempt to start the engine can be
made.
Preheating device with automatic
heating timer (additional equipment)
The preheating light „5“ lights up additionally at
temperatures below 0° Celsius (Fig. 24).
– After the light has gone out, start the engine
without delay.

Automatic electrical shutdown system
(additional equipment)
This is characterized by a brief flashing of all
pilot lamps once the starter key has been turned
to position I (Fig. 24).
Important !
If the engine cuts out immediately after starting
or switches off by itself during operation, a
monitoring element in the automatic shutdown
system has tripped. The corresponding indicator
light (Fig. 24, positions 2 - 4) will come on.
After the engine has stopped, the display con-
tinues 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 6).
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-
