There are two types of instrument panels, “Standard” and
“De luxe”.
Standard
1. Rev. counter
The rev. counter shows the engine speed. Multiply the
value by 100 to calculate revolutions per minute.
Full throttle: operating range,
MD22: 3200–4000r/min.
MD22L: 2700–3000 r/min.
TMD22 : 4100–4500 r/min.
2. Hour counter
Shows the engine operating time in hours and tenth of an
hour.
3. Alarm (siren)
Sounds when lubricating oil pressure is too low
(engine), when coolant temperature is too high or
there is a loss of charge.
4. Warning display
The display has four “windows”. If the acoustic alarm
comes on, one of windows “A−C” starts to blink (red)
to show the cause of the alarm.
A. Coolant too hot. Reduce the speed to idling (in
neutral) until the temperature decreases.
Investigate the cause of the alarm (e.g. restrict-
ed water supply to the engine). Stop the engine if
the temperature does not decrease.
B. Lubricating oil pressure too low. Stop the engine
immediately and locate the cause of the alarm.
C. Alternator not charging.
D. Pre-heating (indicator lamp comes on when glow
plugs are on).
NB. This lamp also works as a filament guard for
the glow plugs. This will also be lit when the key
switch is in position I (operating position) if there is
a fault in the system (break).
Lamp Test (before starting):
All the warning lights will be on but will not flash (for a
maximum of 20 seconds) after the key switch has
been put in the “Running” position (I). The warning
light for high coolant temperature (A) will then go off.
