11. EXPLANATION
OF COMPONENTS
112.1
HOURMETER
The hourmeter electrically records the actual hours of engine operation. The
purpose of the hourmeter is to indicate when to perform the recommended
maintenance
and lubrication
operations.
The hourmeter
will register only
when the engine is running.
While the engine is running, operation display (1) in red at the end of the
meter will advance in l/IO hour increments.
Meter (2) will advance by 1 for
each hour of operation regardless of the engine speed.
112.2
TRANSMISSION
OIL FILTER
WARNING
LIGHT
The transmission
oil filter warning
light will glow amber when the oil filter
element reaches the maximum allowable restriction.
11.2.3 ENGINE COOLANT TEMPERATURE
GAUGE
This gauge shows the temperature
of the coolant circulating
through the
engine. After the engine has operated a sufficient length of time, the pointer
must be in the GREEN (1) area of the gauge. During normal operating, the
gauge readings may vary
between
the minimum and maximum indicated by
the GREEN area of the gauge. Continuous
engine operating below (2) the
minimum temperature is harmful to the engine oil, low coolant temperatures
will also cause exhaust smoke and increase the rate of fuel consumption.
REMARK
In cold weather,
it may be necessary
to cover part of the radiator to
maintain the minimum coolant temperature indicated at the lower end of the
GREEN area.
1
The engine temperature,
under full load conditions,
should remain in the
GREEN area of the gauge. Continuous overheating (3) indicates the need for
mechanical correction. A clogged cooling system or a low coolant level will
also cause high operating temperatures.
