c.
Close the accumulator blowdown valve (1) and pump several strokes on the hand pump (4).
d
Observe the accumulator pressure gauge (3). The gauge should show a rapid pressure rise from zero to the
nitrogen precharge pressure, where it will remain without change for several additional strokes of the hand
pump Log the precharge pressure (1500 psi is normal).
NOTE
An accumulator pressure of 1500 psi when the ambient temperature is above 40F
will provide adequate cranking to start the engine. Between 40F and 0F, 2500
psi should be sufficient. Below 0F, the accumulators should be charged to 3250
psi. For ambient temperatures below 40F', use a starting aid.
e.
Use the hand pump (4) to raise the accumulator pressure.

Sound both fuel oil tanks to determine the level of fuel oil. The fuel tanks should be kept as full of fuel as
possible to minimize condensation of water within the tanks. Replenish the fuel tanks according to the
following procedure (refer to figure in para 1-1 3 for steps d through f):
WARNING
Before fueling the tanks ensure that firefighting equipment is immediately available
