2-31. TEST/REPLACE SOLENOID VALVE(Continued)
OPERATIONAL CHECK:
WARNING
Touching exhaust system during test can cause severe burns.
CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU
Exposure to exhaust gases produces symptoms of headache, dizziness, loss of muscular control,
drowsiness, or coma. Brain damage or death can result from severe exposure.
Fumes from engines become concentrated with poor ventilation. Operate engine in a ventilated
area only.
While running engine, be alert for fumes. If someone is overcome, expose to fresh air; keep warm
and still; give artificial respiration if needed. Seek medical attention. Administer oxygen, if
available.
GOOD VENTILATION IS THE BEST DEFENSE AGAINST EXHAUST POISONING.
1 Test engine shutdown capability and fuel flow when solenoid valve is normally open and closed. Try to start
engine without pushing in OIL BY-PASS SWITCH. Engine should not start. Do not crank engine for more than
30 seconds. This procedure will test the valve's shutdown (closed) capability.
2 Start engine with OIL BY-PASS SWITCH pushed in. If engine starts and oil pressure reaches at least 25 psi
(172 kPa), release button. Engine should continue to run. Some adjustment of the valve may be necessary.
3 Start engine. If engine malfunctions, refer to troubleshooting guide.
