OPERATION IN EXTREME COLD - Continued
Engine Cold Start
NOTE
Under conditions of extreme cold, it is necessary to use the intake heaters to warm the intake
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.
9.
Remove spare flexible coupling from subframe and stow in storage 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.
OPERATION IN STRONG WINDS AND SANDY OR DUSTY CONDITIONS
1.
Bank soil around fuel drums, especially on down slope side, to a height that will prevent wind from rolling or shifting
drums.
2.
Shield couplings during connection or disconnection to prevent entry of foreign material into system.
3.
Keep dust caps in place on all disconnected couplings.
4.
Inspect and clean engine air filter frequently to avoid accumulation of sand or dust.
