Burn Prevention
Do not touch any part of an operating engine system.
The engine, the exhaust, and the engine
aftertreatment system can reach temperatures as
high as 650 °C (1202 °F) under normal operating
conditions.
At idle engine speed and/or zero vehicle speed, an
operator can request a manual regeneration. Under
this condition, the exhaust gas temperature can reach
650 °C (1202 °F). Otherwise automatic regeneration
can produce exhaust gas temperatures as high as
650 °C (1202 °F).
Allow the engine system to cool before any
maintenance is performed. Relieve all pressure in the
following systems, hydraulic system, lubrication
system, fuel system, and the cooling system before
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, allow if active the
regeneration active lamp to be extinguished before
any service or repair is performed.
Induction System
Sulfuric Acid Burn Hazard may cause serious per-
sonal injury or death.
The exhaust gas cooler may contain a small
amount of sulfuric acid. The use of fuel with sulfur
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 appropriate
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 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 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 in
order 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
Hot oil and hot lubricating components can cause
personal injury. Do not allow hot oil to contact the
skin. Also, do not allow hot components to contact the
skin.
Batteries
Electrolyte is an acid. Electrolyte can cause personal
injury. Do not allow electrolyte to contact the skin or
the eyes. Always wear protective glasses for
servicing batteries. Wash hands after touching the
batteries and connectors. Use of gloves is
recommended.
