11-2 Pretrip inspection and maintenance
General service precautions
WARNING
• Never run the engine in a poorly ventilated
area. Diesel exhaust will replace the
breathable air within an enclosed space,
possibly resulting in unconsciousness or
death.
• Batteries release a gas mixture that is
explosive. Do not smoke when working
around batteries. Put out all flames and
remove any source of sparks or intense
heat.
• Battery acid is extremely harmful if
splashed in the eyes or on the skin. To pre-
vent personal injury, always wear a face
shield and protective clothing when work-
ing around batteries.
• Battery posts, terminals, and related
accessories contain lead and lead com-
pounds, chemicals known to the State of
California to cause cancer and reproduc-
tive harm. To prevent possible personal
injury, always wash your hands after han-
dling battery parts and related accesso-
ries.
• Use extreme care when tilting the cab with
the engine running. Chock all the tires fore
and aft, set the parking brake, and place
the transmission in park. If the engine is
running, the vehicle could move, causing
an accident that could result in personal
injury or property damage
.
After lowering the cab, check that it is
locked securely in position. P. 11 - 5
• To avoid burns, do not touch the engine,
exhaust manifold, radiator, exhaust pipe,
or other parts in the engine compartment
until they are cool.
• To prevent scalding, do not remove or
loosen the radiator cap until the coolant
temperature is below 122×F (50×C).
• Never work around or under a vehicle that
is supported only by a jack. Always sup-
port the vehicle with safety stands. Jacks
can slip, causing the vehicle to fall, which
could result in serious injury or death.
• If a metal object connects an ungrounded
battery terminal to a nearby metal part of
the vehicle which is grounded, it could
short out the batteries, causing sparks and
possible personal injury or property dam-
age.
