Cold engine start Engine hard to start at low temperature
Possible cause Remedy
Starting speed too low. Preheat engine.
Low charge battery. Fit fully charged battery.
High oil pressure. At cold start an oil pressure reading
of up to around 7 bar (102 psi) does
not indicate a malfunction.
Oil pressure too low after
cold start.
Too much resistance in the oil suc-
tion 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 oil pressure
should be above 1.5 bar (22 psi).
Otherwise, the speed must be low-
ered 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 temperature of
minimum 50 °C (120 °F). Be sure the oil pressure does not go
below minimum at idle.
