2 General information
Information on the document
This Operator's Manual was created with due care. It is exclusively intended
to offer a technical description of the machine and to provide instructions on
commissioning, operating and maintaining the machine. When operating the
machine, the applicable standards and legal regulations as well as any inhouse regulations apply.
Before commissioning, during operation and before maintenance work is begun on the machine, read the Operator's Manual carefully and keep it close
by for ready access.
Machine
This Operator's Manual describes the following machine.
Machine name HATZ diesel engine
Type number 1B20, 1B27, 1B30, 1B40, 1B50
Customer service
Have service work performed by qualified technicians only. We recommend
that you work with one of the over 500 HATZ service stations. Trained specialists there will repair your machine with Hatz original spare parts and
with HATZ tools. The global HATZ service network is at your disposal to advise you and supply you with spare parts. For the address of the Hatz ser-
vice station nearest you, please see the directory included or visit the internet at: www.hatz-diesel.com
Problems may occur if unsuitable spare parts have been installed. We cannot accept responsibility for damage and secondary damage that result from
this.
We therefore recommend the use of genuine Hatz original spare parts.
These parts are manufactured according to strict Hatz specifications and
achieve maximum operational reliability through their perfect fit and functionality. The order number can be found in the enclosed spare parts list or on
the internet at: www.hatz-diesel.com
Exclusion of liability
The manufacturer cannot be held responsible for personal injury, damage to
property, or damage to the machine itself caused by improper use, foreseeable misuse, or failure to follow or adequately follow the safety measures
and procedures described in this Operators Manual. This also applies to
changes made to the machine and the use of unsuitable spare parts.
Modifications, which serve technical improvement, are reserved.

3.2.2 Machine-specific safety instructions for operation
Introduction
The machine can pose residual risks during operation. To eliminate these
risks, all persons working on the machine must follow the general and machine-specific safety instructions.
If you have an engine that is not yet installed in a machine, it is imperative
that you follow the Assembly Instructions for HATZ Diesel Engines before installing the engine.
These assembly instructions contain important information on safe installation.
If the engine is installed in a machine or assembled with other machines to
form a machine, it is prohibited to start the engine before it has been determined that the newly created machine fulfills all safety-related requirements
and applicable legal regulations.
Safe operation
▪ Before switching on the machine, ensure that no one can be injured when
the machine is started up.
▪ During machine operation, ensure that unauthorized persons do not have
access to the area in which the machine has an impact.
▪ Parts of the exhaust gas system and the surface of the engine become hot
during operation. Risk of injury from touching hot parts! Let the engine cool
before maintenance.
▪ Do not refuel during operation.
HATZ
Faults
▪ Immediately eliminate faults that compromise safety.
▪ Switch off the machine and do not take into service again until all faults
have been eliminated.
Safety instructions for operation

Toxic engine exhaust gases can lead to loss of consciousness
and even death in closed-off and poorly ventilated rooms.
▪ Never operate the machine in closed-off or poorly ventilated
rooms.
▪ Do not breathe in the exhaust gases.
15Operator's Manual
Safety 1B20, 1B27, 1B30, 1B40, 1B50

4.3 Physical operating conditions
Engine adjustment
The engine is normally adjusted to operate within the standard reference
conditions stipulated in ISO3046-1:
Parameter Unit Value
Intake air temperature °C +25
K 298
Relative humidity % 30
Air pressure
(at approx. 100 meters above sea
level)
NOTICE
If the machine is operated at high altitudes and high temperatures, adjustment of the engine setting may be necessary if the
climatic conditions were not taken into account when the machine was ordered. If this is the case, please contact your nearest HATZ service station.

4.4 Engine oil
Oil quality
All brand name oils that satisfy at least the following specification are suitable:
▪ ACEA – B3 / E4 or better
▪ API – CF / CH-4 or better
If engine oils of a low quality standard are used, the oil change interval must
be reduced to 150 operating hours.
Oil viscosity
HATZ
Choose the recommended viscosity based on the type of start (recoil,
crankhandle or electric) and on the engine temperature at which the engine
will be operated.
CAUTION
Engine damage from unsuitable engine oil.
Unsuitable engine oil considerably reduces engine service life.
Only use engine oil that fulfills the specifications stipulated
above.

4.5 Fuel
Fuel type
All types of diesel fuel that meet the minimum requirements of the following
specifications are suitable:
▪ EN 590 or
▪ BS 2869 A1 / A2 or
▪ ASTM D 975- 1D / 2D
CAUTION
Danger of engine damage from low quality fuel.
The use of fuel that does not meet the specifications can lead to
engine damage.
▪ The use of fuel that does not meet specifications requires
approval by Motorenfabrik HATZ (main plant).

Safety notes
WARNING
Danger of injury from improper lifting and transport.
Danger of crushing from falling or tipping of the engine.
▪ Only use the lifting eye already mounted on the machine for
lifting.
▪ Only use a suitable hoist with a sufficient carrying capacity.
▪ Do not remain under suspended loads.
CAUTION
Only use the lifting eye for transporting the engine.
Do not use for lifting the entire machine.
CAUTION
Danger of injury from overloading the body.
