Operation
Correct operation is the key to fuel economy and engine service life. Always allow the engine to achieve normal
operating temperature before running it at full power. Avoid opening the throttle too quickly and running the engine
at high engine speeds.
IMPORTANT! An automatic shut-off for oil pressure and engine coolant temperature (ECT) must be installed
during unattended operation where the Volvo Penta instrument box is not being used.
Alarms and fault indications
If the Volvo Penta instrument box is used, the following ap-
plies:
●
If oil pressure is too low or engine coolant temperature (ECT) too
high, the engine stops automatically and the acoustic alarm goes
off.
If the engine is equipped with an alarm separator, the relevant
warning lamp also lights.
●
If the engine coolant level is too low and the engine is equipped
with an engine coolant level switch, the engine stops automati-
cally and the acoustic alarm goes off. The warning lamp lights.
● If generator charging drops, the warning lamp lights.
For other applications see the Instruction Manual for the rele-
vant application.
Engine speed control
Power pack: The engine speed (RPM) is adjusted using the
mechanical engine speed control (1). This is mounted on the instru-
ment box.
Other engines: See the relevant instruction manual.
Checking instruments
Check the instruments directly after starting the engine and then at
regular intervals while operating the engine. The needles should be
within the green range.
Engine coolant temperature: 75–95°C (167–203°F)
420, 620 VE: 83–95°C (181–203°F)
520, 720 GE: 83–95°C (181–203°F)
520, 720, 721 VE: 87–102°C (189–216°F)
Oil pressure, engine at operating temperature: 300–500 kPa. At
engine idle this is normally lower.
IMPORTANT! The lubricating oil level must be checked at
least every eight hours if the engine is running continuously.
See chapter “Maintenance, Lubricating system”.
