2 Oil pressure gauge
The oil pressure is dependent on the temperature of the oil and the engine speed.
Since the engine is fitted with an oil cooler, there can be some slight delay before the
oil pressure gauge gives a reading. If the engine is cold, it will show relatively high
pressure, which is normal. If the pressure should at any point go down to zero, the
engine must be stopped immediately and the reason determined. See under “driving”
page 13 &15
3 Temperature gauge for cooling water
The temperature gauge shows the temperature of the cooling water and thus the
working temperature of the engine. The temperature should normally be 70-90C
(158-196F). If it should indicate a high temperature for a long time, this can depend
upon the fact that the cooling system channels are blocked and are preventing
circulation or that the thermostat has been damaged. In such cases the cooling
system should be cleaned (see 21) or the thermostat should be replaced.
4 Temperature gauge for engine oil
The oil temperature is a function of the engine speed and can vary quite
considerably. Temperatures above 130C (265F), however, should not be permitted.
5 Revolution counter
The revolution counter shows the engine speed in revolutions per minute. The
indicator should not go up as far as the red field on the instrument.
6 Warning lamp for charging
The lamp lights up when the battery is discharging which is normal at idling speed. If
you accelerate a little, the lamp should go out. Should the lamp remain on while you
are driving, this usually means that there is some fault in the electrical system or that
the fan belt is insufficiently tensioned and is slipping on the generator pulley. The
result of this will be poor charging.
7 Choke control
To use the choke control pull it out
vertically (A) and lock it by turning it
quarter of a turn (B). To return the
control, twist it back to its vertical
position. When the engine is thoroughly
warmed up the choke control should be
all the way in. See under “Driving”, page
