2-7.OPERATION IN EXTREME HEAT
The engine of the centrifugal pump unit is air cooled. Heat can be removed from an engine in three ways: engine
exhaust, engine oil, and the passage of air across and through cylinder cooling fins. Therefore, when operating in high
ambient temperatures, observe the following:
a.
With engine stopped, inspect frequently to be sure that cylinder cooling fins are clean and free of dirt that
inhibits cooling.
b.
With engine stopped, inspect frequently to be sure that flywheel blower ring is clean and free of dirt.
c.
With engine stopped, inspect frequently
to be sure that engine oil is to top mark on dipstick
(1). Add oil, if necessary, at oil filler cap (2) to bring
level up to top mark.
d.
Check the air cleaner restriction indicator (1).
If red band appears in window of restriction indicator,
change the air filter in air cleaner (2). Refer to paragraph
3-4.
