Always use leakproof containers when you drain
fluids. Do not pour waste onto the ground, down a
drain, or into any source of water.
Diesel Exhaust Fluid
DEF is an aqueous solution of urea which can re-
lease ammonia vapors. Always wear the appro-
priate Personal Protective Equipment (PPE) that
is noted on a material safety data sheet (MSDS)
for Diesel Exhaust Fluid (DEF).
• Do not inhale ammonia vapor or mist
• Do not eat, drink, or smoke in presence of DEF
• Avoid DEF contact with eyes, skin, and
clothing
• Wash thoroughly after handling DEF
Always follow the directions for first aid that are
noted on a material safety data sheet (MSDS) for
Diesel Exhaust Fluid (DEF).
DEF is not expected to produce significant adverse
health effects when the recommended instructions
for use are followed.
• Draining DEF must be carried out in a well
ventilated area.
• Do not allow the DEF to be spilled onto hot
surfaces.

Burn
Prevention
Do
not
touch
any
part
of
an
operating
engine
system.
The
engine,
the
exhaust,
and
the
engine
aftertreatment
system
can
exceed
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,
aftertreatment system or 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 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.
