Always use leakproof containers when you drain
fluids. Do not pour waste onto the ground, down a
drain, or into any source of water.

Burn
Prevention
Do
not
touch
any
part
of
an
operating
engine
system.
The
engine
and
the
exhaust
system
can
reach
temperatures
as
high
as
650°
C
(1202°
F)
under
normal
operating
conditions.
Allow
the
engine
system
to
cool
before
any
maintenance
is
performed.
Relieve
all
pressure
in
the
air
system,
hydraulic
system,
lubrication
system,
fuel
system,
and
the
cooling
system
before
the
related
items
are
disconnected.
Contact with high pressure fuel may cause fluid
penetration and burn hazards. High pressure fuel
spray may cause a fire hazard. Failure to follow
these inspection, maintenance and service in-
structions may cause personal injury or death.
After the engine has stopped, wait for 10 minutes to
allow the fuel pressure to be purged from the high-
pressure fuel lines before any service or repair is
performed on the engine fuel lines. The 10 minute
wait will also allow static charge to dissipate from the
low-pressure fuel system.
Allow the pressure to be purged in the air system, in
the hydraulic system, in the lubrication system, or in
the cooling system before any lines, fittings, or
related items are disconnected.
Induction System
Sulfuric Acid Burn Hazard may cause serious
personal injury or death.
The exhaust gas cooler may contain a small
amount of sulfuric acid. The use of fuel with sul-
fur levels greater than 15 ppm may increase the
amount of sulfuric acid formed. The sulfuric acid
may spill from the cooler during service of the en-
gine. The sulfuric acid will burn the eyes, skin
and clothing on contact. Always wear the appro-
priate personal protective equipment (PPE) that
is noted on a material safety data sheet (MSDS)
for sulfuric acid. Always follow the directions for
first aid that are noted on a material safety data
sheet (MSDS) for sulfuric acid.
Coolant
When the engine is at operating temperature, the
engine coolant is hot. The coolant is also under
pressure. The radiator and all lines to the heaters and
to the engine contain hot coolant.
Any contact with hot coolant or with steam can cause
severe burns. Allow cooling system components to
cool before the cooling system is drained.
Check that the coolant level after the engine has
stopped and the engine has been allowed to cool.
Ensure that the filler cap is cool before removing the
filler cap. The filler cap must be cool enough to touch
with a bare hand. Remove the filler cap slowly to
relieve pressure.
Cooling system conditioner contains alkali. Alkali can
cause personal injury. Do not allow alkali to contact
the skin, the eyes, or the mouth.
Oils
Skin may be irritated following repeated or prolonged
exposure to mineral and synthetic base oils. Refer to
your suppliers Material Safety Data Sheets for
detailed information. Hot oil and lubricating
components can cause personal injury. Do not allow
hot oil to contact the skin. Appropriate personal
protective equipment should be used.
Diesel Fuel
Diesel engines have high-pressure fuel systems and
the fuel can reach temperatures of over 100° C
(212° F). Ensure that the fuel has cooled before any
service or repairs are performed.
