Low ambient temperatures
Lubricating oil
z
Select lubricating oil according to ambient
temperature
(
22
)
and consult DEUTZ part-
ner if necessary.
z
Halve the oil change times in case of fre-
quent cold starts.
Fuel
z
Below 0 °C use winter fuel
(

)
.
Battery
z
A well-charged battery
(

)
is a prerequisi-
te for starting the engine.
z
Heating the battery to about 20 °C improves
the starting behaviour of the engine. (Remo-
ve and store the battery in a warm room).
Cold start aid
z
Heating plugs, heating flange, spark plug
system can be used as cold start aids, for
example.

High ambient temperatures, high
altitude
Under the following application and operating
conditions, the amount of fuel must be redu-
ced.
z
above 1000 m altitude
z
above 30 °C ambient temperature
Reason: When the altitude or ambient tempe-
rature increases, the air density decreases.
This reduces the amount of oxygen in the en-
gine intake air and the fuel-air mixture would
be too rich if the injected amount of fuel were
not reduced.
z
The results would be:
black smoke in the exhaust
high engine temperature
reduction in engine performance
poss. impairment of the start behaviour
Consult your equipment supplier or DEUTZ
partner if you have any other questions.
Under the following operating conditi-
ons, the amount of fuel is reduced au-
tomatically, controlled by the electronic
control unit.
