A Pyrometer (option)
An engine pyrometer system indicates the
exhaust temperature, which helps the opera-
tor get the best efficiency from the engine.
Variations in engine load can cause the ex-
haust temperature to vary. For example,
high exhaust gas temperature is the result
of prolonged engine lugging or overfueling.
If the pyrometer reading shows that exhaust
temperature exceeds normal, reduce fuel to
the engine until exhaust temperature is re-
duced. Shift to a lower gear if the engine is
overloaded.
