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)
kPa 100
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.

CAUTION
Damage to the diesel oxidation catalyst (DOC) from using
unsuitable engine oil.
Unsuitable engine oil diminishes the functionality and service life
of the catalytic converter.
Only use engine oils with very low quantities of sulfate ash,
phosphor and sulfur – so-called "low SAPS" oils which fulfill at
least one of the specifications mentioned above.
Engines without diesel oxidation catalyst (DOC)
(for details, see chapter 4.2.1 Engine serial number, page 26).
▪ 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
28
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:
▪ Europe: EN 590
▪ UK: BS 2869 A1 / A2
▪ USA: ASTM D 975-09a 1-D S15 or 2-D S15
▪ USA: ASTM D 975-09a 1-D or 2-D
(only suitable for engines without diesel oxidation catalyst - DOC)
For details with regard to equipping with DOC, see chapter 4.2.1 Engine
serial number, page 26
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).
CAUTION
Danger of malfunctions due to old fuel.
When diesel fuel is stored in a fuel tank or canister for lengthy
periods, deposits may form on account of fuel aging. These deposits result in malfunctions due to clogged fuel filters and damage to the injection system.
▪ Perform the prescribed storage steps in machines that will
be out of use for more than three months (see section10.1
Storing the machine, page 100).
▪ Only refuel with fresh diesel fuel such as can be obtained
from filling stations.
