6.2 Fuels and lubricants
Oil viscosity
Choose the oil viscosity in dependence on the ambient tempera-
ture at the operating location of the engine (see diagram).
Occasional falling short of the temperature limit (e.g. use of SAE
15W/40 down to -15 °C (+5 °F)) may effect the cold starting ability
of the engine, but will not cause any engine damage.
Temperature related lubrication oil changes can be avoided by
using multi-purpose oils. The following oil change intervals apply
also when using multi-purpose oils.
Oil quality
You should preferably use oils of API quality class CD/CE/CF/
CF-4/CG-4 or higher, or ACEA B2/E2.
Lubrication oil change intervals
1 months or 250 operating hours
When changing to a higher alloyed oil quality after a
longer period of operation, it is recommended to per-
form the first oil change of the higher quality oil already
after 25 operating hours.
Quality
You should only use commercially available brand diesel fuel and
ensure strict cleanliness when filling in.
The fuel provision should always be topped up in due time, so that
the tank will not run dry.
The following fuel specifications are permitted:
n
EN 590
n
BS 2869: A1 and A2
n
ASTM D 975 1-D and 2-D
For engines used in EPA areas, the use of fuels with a ultra-low
sulphur content is mandatory.
United States Environmental Protection Agency
Winter fuel
For winter operation use only winter diesel fuel, to avoid clogging
because of paraffin separation. At very low temperatures disturbing
paraffin separation can also be expected when using winter diesel
fuel.
The hydraulic system is operated with hydraulic oil HV 32 (ISO)
with a kinematic viscosity of 32 mm
2
/s at 40°C (104 °F).
For topping up or for oil changes use only high-quality hydraulic oil,
type HVLP according to DIN 51524, part 3, or hydraulic oils type
HV according to ISO 6743/3. The viscosity index (VI) should be at
least 150 (observe information of manufacturer).
