Do not permit personnel to stand between or outboard of the engines during blowdown.
Failure to comply can result in injury or death.
High noise levels are present in the engine room and AMS 1 when the engines are operat-
ing. Hearing protection must be worn at all times when the engines are operating. Failure

tions. Release the ENGINE START pushbutton when finished cranking.
! CAUTION
If there is any sign of water or oil being ejected at the cylinder test valves, or any indication of
obstruction while rotating the engine, refer to unit maintenance. Do not attempt to start the
engine until the problem has been corrected, or serious damage to the main engine could result.
d.
Check the port main engine test valves (figure 10, item 1) and air box blow down valves (figure 13, item 6) for the
presence of oil and/or water. If no oil or water are detected, continue with this procedure. If oil or water are

cation.
