Instruments and
Controls
All controls for the marine
diesel are located so that they are accessible from the right-hand
side of the engine.
The instrument panel, supplied separate from the engine, contains
coolant thermometer, oil pressure gauge,
starting switch, starting button, instrument panel lighting and
charging indicator lamp.

Before
starting up a new engine, check location, operation and effect
of the various controls. Make a habit
of glancing at the instruments every now and then during running
to ensure discovery of abnormal readings in
good time.

Oil pressure gauge
The oil pressure gauge shows the oil pressure in the engine
lubricating system. It does not, however, show
how much oil there is in the crankcase. At normal r.p.m. and load
the pressure is to be 40-60 lb/sq.in.
( 3-4 kg/sq.cm. ). Higher pressure than the above can be caused by
oil that is too viscous for the prevailing temperature.
If the oil pressure falls to zero or near to it during running, the
engine must be stopped immediately and the fault traced..
Coolant
thermometer
The thermometer shows the temperature of the coolant and,
consequently, the working temperature of the engine.
Normal coolant temperature is 160-175 deg F ( 70-80 deg C ). If the
normal temperature shows excessively high temperature for a long
period at a time, this may be due to circulation difficulties
causedby clogged cooling
system passages,
Charging
indicator lamp
Normally, the charging indicator lamp is not alight when the engine
is running; this shows that the battery is
being charged. When the lamp lights this indicates that the battery
is discharging, which is normal when idling. If
the lamp lights when running at higher speeds, there is usually a
fault in the electrical system.
Starting switch
The starting switch is below the thermometer on the instrument
panel. The circuit is closed through the switch
when the key is turned clockwise. Do not forget to switch off the
current when the engine is stopped.. Otherwise
the battery will discharge.
Starting button
The engine is started electrically by pressing in the starting
button to the left of the starting switch on the
instrument panel. Release the button as soon as the engine starts.
On the left-hand side of the instrument panel there is a switch for
the panel lighting.
