It is the responsibility of the operator assigned to
the Chrysler Air-Raid Siren to make sure that it is in perfect condition
to run at full efficiency at a moment's notice.
The following items should be checked by the operator
immediately upon taking over his watch.
Check quantity of gasoline in fuel tank. (Be sure
there are at least five gallons in the tank.)
Check water level in radiator. (In cold weather
check anti-freeze solution.)
Check oil in crankcase. (Be sure it is up to the
running level shown on the oil level indicator rod.)
- Remove any loose material from the ledge in front of the air
intake to avoid any possible damage to the blower unit.
NOTE: THE ENGINE SHOULD BE STARTED AND RUN AT
IDLE SPEED WITH CLUTCH DISENGAGED, FOR A PERIOD OF FIVE MINUTES, OR, IN
COLD WEATHER, UNTIL NORMAL OPERATING TEMEPRATURE IS REACHED.
