Instruction manual

16
Change the oil again after running 100–150 hours and
change the oil filter (filters) at the same time. Never flush
out the engine with flushing oil since the bearing pressures
in a diesel engine are too high for the use of this kind of oil
to be suitable.
The oil in the reverse gear (and the filter element on SCG)
should be changed for the first time after 100-150 hours of
operation.
The oil is subsequently changed at the normal intervals gi-
ven in the servicing scheme.
During running
Frequently check during running that all the instruments give normal readings. Some of the instruments are optional
equipment, see page 10.

Observation
Remarks/Actions
Engine lubricating oil
pressure
8
300-500 kPa (3-5 kp/cm
2
= 43-71
p.s.i.), normally during operation
Avoid stoppages for want of fuel. If
this should happen, the fuel system
must be vented, after filling with
fuel.
Warning lamp (low oil
pressure)
17
The lamp should not light. It lights
only when the pressure falls below
150 kPa (1.5 kp/cm
2
= 21 P.s.i.).
If the lamp lights or if the siren is
heard the oil pressure is too low.
Stop the engine. Remedy the
fault.
Warning siren
20
The siren is heard if the oil pressu-
re falls below 150 kPa (1.5 kp/cm
2
=
21 p.s.i.).
Engine coolant tempera-
ture
10
65-95°C (150-203°F) normally
during operation.
If the lamp lights and the siren is
heard the engine temperature is
too high. Stop the engine. Re-
medy the fault.
Warning lamp (coolant
temperature)
18
The light should not come on.
(Lights if engine temp. exceeds
approx. 95°C = 203°F, the siren
is also heard).
Charging voltage
5
During normal running approx. 28
volts for 24 V system and approx.
14 volts for 12 V system.
If the voltage drops to 24 (or 12)
volts during running, the batteries
are not being charged. Remedy
the fault as soon as possible.
Warning lamp (battery
charging)
16
The lamp should not light. The batteries are not being char-
ged if the lamp lights up. Remedy
the fault as soon as possible.
Turbo-charging pressure
21
Normal pressure, see ”Technical
data”. The pressure depends great-
ly on the output. The engine should
run at full load for 2-3 minutes befo-
re reading the pressure gauge.
The charging pressure is consid-
erably lower than those values gi-
ven in ”Technical Data”, unless full
engine output can be developed.
Check that the charging pressure
does not drop unduly from the nor-
mal test pressure reached for the
boat in question.
Reverse gear oil pressu-
re
15
The pressure should correspond
with the values given in ”Technical
data”, pages 40 and 41.
Slipping can occur if pressure is
too low. This can cause damage
to the reverse gear.
