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.

This Operator's Manual describes the following machine.
Machine name HATZ diesel engine
Type number 2-4L41C 2-4M41 2-4M41Z 4M42 4L42C
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 serv-
ice station nearest you, please see the directory included or visit the Internet at: www.hatz-diesel.com
Problems may occur if unsuitable spare parts are installed. We cannot accept responsibility for damage and secondary damage that result from this.
We therefore recommend the use of 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 included spare parts list or on the Internet at:
www.hatz-diesel.com

safety instructions be followed.
Read this chapter carefully before beginning work.
3.1.1 Intended use and foreseeable misuse
Intended use
The machine described in this Operator's Manual fulfills the following functions:
▪ Diesel engine intended for installation in a machine or for assembly with
other machines to form a machine. See the chapter 11 Installation decla-
ration, page 103.
This engine is intended exclusively for the purpose specified and tested by
the manufacturer of the machine into which the engine is installed.
Any other use is not intended and therefore not permitted. Violations compromise the safety of the personnel working with the machine. Responsibility

4.2 Fuel
HATZ
Fuel type
Winter fuel
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).
When outside temperatures drop below 0 °C, use winter fuel or mix in petroleum in advance:

4.3 Engine oil
Oil quality
All oil brands that meet at least one of the following specifications are suitable:
▪ ACEA – B2 / E2 or better
▪ API – CD / CE / CF / CF-4 / CG-4 or better
If engine oils of a low quality standard are used, the oil change interval must
be reduced from 250 to 150 or from 500 to 250 operating hours depending
on the engine specification.

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.
Using engine oil that does not meet the above specifications
considerably shortens the engine service life.
