Oil pressure gauge
This gauge indicates oil pressure in
the engine lubricating system. The
indication of the gauge should be 1–3
kg/cm
2 when the engine is at idle ; it
should be 3–6.5kg/cm 2 when the
engine is running at medium speed.
When the gauge needle does not
move upward at all or hydraulic pres-
sure changes abruptly, check the oil
level in the engine crankcase. If the
oil level is found normal, have the
hydraulic system checked by your
nearest Daewoo dealer.
Do not run the engine with low oil
pressure indication.
Air pressure gauge
Air pressure gauge indicates air pres-
sure in the air tanks. While driving,
the gauge needle must be within the
range of 5.3–8.2kg/cm
2 .
Be habitual of watching the gauge,
while driving, to make sure the gauge
needle indicates the normal condi-
tions.
Engine tachometer
The tachometer indicates the engine
speed in revolutions per minute(rpm)
and red colored zone represents
critical engine speed.
Excessively high engine rpm(red col-
ored zone) may cause damage to the
engine.
To drive economically, keep the
engine within 1,000
Ŕ
2,000rpm.
Maximum allowable engine speed :
D1146 ENG : 2,500rpm.
D1146Ti/DE12/DE12T ENG.
: 2,200rpm.
DE08TiS ENG : 2,300rpm.
DE12Ti/DE12TiS ENG.:2,100rpm

If the gauge needle stands in the
red zone, warning lamp comes on
and alarm buzzer sounds. Imme-
diately stop the vehicle, check for
unusual conditions, run the engine
at a moderately fast idle speed to
increase air pressure, then drive off.
