Oil level Oil level is increasing
Cold engine start Engine hard to start at low temperature
Possible cause Remedy
Oil too cold during engine op-
eration.
Cover oil cooler surface, maintain the
oil temperature prescribed.
Contamination with diesel fuel. Check fuel.
Possible cause Remedy
Starting speed too low. Preheat engine.
Low charge battery. Fit fully charged battery.
High oil pressure. At cold start a pressure reading of up to
around 7 bar (102 psi) does not indi-
cate a malfunction.
Oil pressure too low after cold
start.
Too much resistance in the oil suction
system at low temperatures due to cold
oil. Stop engine and preheat oil.
After a cold start the oil tank must be
observed and the pressure should be
above 1.5 bar (22 psi). Otherwise, the
speed must be lowered again, because
not enough cold oil can be sucked.
If oil pressure is reading lower than
1 bar (15 psi) oils with lower viscosity
are to be used.
See SI-912 i-001, current issue.
NOTE: Oil pressure must be measured at idle at an oil tem-
perature of minimum 50 °C (120 °F).
Be sure the oil pressure does not go below mini-
mum at idle.
