b. EngineColdStart.
NOTE
Underconditionsof extremecold,it is necessaryto usetheintakeheatersto warmtheintake
manifold before attempting to start the engine. The amount of warming required increases as the
temperature decreases. At 20* F (-7* C), holding the intake heaters on for 30 seconds is sufficient;
at -25* F (31.7* C ) approximately 2.5 minutes is required.
(1)
Unlatch engine module from pump-engine module frame and slide engine module out far enough to disengage
engine flexible coupling adapter from the flexible coupling (5-6 inches).
(2)
Insert spare flexible coupling between the lower part of the engine module and the subframe to prevent the
engine accidentally sliding back and engaging fuel transfer pump.
(3)
At the control panel, hold the ENGINE switch in the START position for 30 seconds, then release. If engine
starts, proceed to step 7.
(4)
Hold INTAKE HEATER switch in the ON position for 2 minutes to heat intake air and allow battery time to
thaw.
(5)
At the control panel, hold INTAKE HEATER switch in the ON position and lift and hold the ENGINE switch
in the START position until engine starts. If engine does not start within 2 minutes, release the ENGINE start
switch and the INTAKE HEATER
switch and allow system to rest for 5 minutes. (Battery will thaw and starter
will cool.)
(6) Repeat steps 4 and 5 as required.
(7) Allow engine to run 2-3 minutes.
(8) Shut down engine IAW para. 2.6.
(9)
Remove spare flexible coupling from subframe and stow in accessory module.
(10)
Slide engine module into pump-engine module and engage engine adapter with flexible coupling.
(11)
Latch engine module to pump-engine frame.
(12)
Perform normal engine start IAW para. 2.5.
2.10.3
Operation in Strong Winds and Sandy or Dusty Conditions.
a.
Bank soil around fuel drums, especially on down slope side, to a height that will prevent wind from rolling or
shifting drums.
b.
Shield couplings during connection or disconnection to prevent entry of foreign material into system.
c.
Keep dust caps in place on all disconnected couplings.
d.
Inspect and clean engine air filter frequently to avoid accumulation of sand or dust.
