A new HATZ Diesel engine - working for you
This engine is intended only for the purpose determined and tested by the manufacturer of the
equipment in which it is installed. Using it in any other manner contravenes the intended purpose.
For danger and damage due to this, Motorenfabrik HATZ assumes no liability. The risk is with the
user only. Use of this engine in the intended manner presupposes compliance with the maintenance
and repair instructions laid down for it. Noncompliance leads to engine breakdown.
Please do not fail to read this operating manual before starting the engine. This will help you to avoid
accidents, ensure that you operate the engine correctly and assist you in complying with the mainte-
nance intervals in order to ensure long-lasting, reliable performance.
Please follow all maintenance references carefully including the schedule for 2008 and later
EPA certified nonroad compression-ignition engines and for 2008 and later CARB certified
Heavy-Duty off-road engines to prevent our environment.
Please pass this Instruction Manual on to the next user or to the following engine owner.
The worldwide HATZ Service Network is at your disposal to advise you, supply with spare parts and
undertake servicing work.
You will find the address of your nearest HATZ service station in the enclosed list.
Use only original spare parts from HATZ. Only these parts guarantee a perfect dimensional stability
and quality. The order numbers can be found in the enclosed spare parts list. Please note the spare
part kits shown in Table M00.
We reserve the right to make modifications in the course of technical progress.

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.
If the engine forms part of the finished equipment or machine, its manufacturer will take all the appli-
cable safety regulations into account.
Nevertheless, we would like you to note certain additional comments on operating safety which
follow. 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 poten-
tially 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 so that they cannot be touched accidentally when the engine is in-
stalled in other equipment or machinery.
Guards are available from HATZ to protect belt drives for 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.
– 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.
– 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.

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 refuel near a naked flame or sparks which could start a fire. 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 the engine while it is running.
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. Contact your next HATZ service station, if a sticker comes off or is illegible and ask
for a new one.
– Note that any unauthorized modifications to the engine absolve 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.
