MALFUNCTION 3.
FUEL PRESSURE STAYS AT 25 PSI OR LESS IN HEAT AUTO OR HEAT MANUAL.
WARNING
Electrical high voltage cannot be seen, but it can kill you. Electricity is unlike most other
dangerous things you can come in contact with because it gives no warning and no symptoms
to be wary of. Its effect is immediate. It can kill you, render you unconscious, or severely burn
you. To ensure your safety and that of other maintenance personnel, always observe the
following precautions:
·
DO NOT perform maintenance on electrical equipment unless all power is removed.
·
BE CERTAIN there is someone assisting you who can remove power immediately.
·
ALWAYS place POWER OFF warning tags on power supply switches so that no one will
apply power while you are performing maintenance.
·
FOR ARTIFICIAL RESPIRATION, REFER TO FM 21-1 1.
Fuel is flammable and toxic to eyes, skin, and respiratory tract. Skin/eye protection required.
Avoid repeated/prolonged contact. Use only in well ventilated areas. Keep away from open
flames or other sources of ignition. Post FUEL FLAMMABLE/No SMOKING signs. Suitable fire
extinguisher must be present.
Fuel on clothing can be fatal if ignited by a static discharge. If fuel gets on your clothes, leave
the refueling area as soon as possible and wet clothes with water before taking them off. In
extreme cold conditions, clothes should not be wet; instead, ground yourself to a piece of
grounded equipment by taking hold of it before taking off the clothes. Wash skin with warm
soapy water.
