Warning Risk Of Burn; Do Not Touch The Engine While It Is Running Or For A While After It Is Stopped; Be Careful When Opening/Closing The Radiator Cap; Replenish Coolant Only When The Coolant In The System Is Cold - Mitsubishi diesel engines Service Manual

SAFETY CAUTIONS
Warning
• œ Do not touch the engine while it is
running or for a while after it is
stopped
Never touch any part of the engine
while it is running or for a while after
it is stopped. Otherwise, you may
become burned.
Use a coolant temperature gauge to confirm that the
engine has sufficiently cooled down before
performing any inspection/service.
• œ Be careful when opening/closing the
radiator cap
Never attempt to open the radiator cap while the
engine is running and for a while after it is stopped.
Stop the engine and wait until the coolant
temperature has sufficiently dropped before opening
the cap.
Slowly open the radiator cap to allow the internal
pressure to escape. To prevent possible burn, wear
thick rubber gloves or cover the cap with cloth to
protect your hands from escaping vapor.
Tighten the radiator cap firmly.
Coolant is extremely hot while the engine is running
or for a while after the engine is stopped. You may
become burned by extremely hot vapor or coolant
that will gush out if the radiator cap is opened.
• œ Replenish coolant only when the
coolant in the system is cold
Do not replenish coolant for a while after the engine
is stopped. Replenish coolant when the coolant in
the system is sufficiently cold. Otherwise, you may
become burned.
• œ Do not remove
material
The exhaust system components become extremely
hot and therefore are covered with heat insulating
material. Never remove the material. If the material
needs to be removed at all for inspection/service, be
sure to install it again after the operation.

Warning

poisonous

• œ Ensure good ventilation while the
engine is running
If the engine is installed inside a
building and the exhaust gas is
directed outside through a duct,
regularly check the duct for any
leakage through the joints etc.
Do not run the engine in a building (warehouse,
tunnel, etc.), confined space, or other poorly
ventilated places if the engine is used for a portable
generator. If the engine needs to be run in a building
at all, ensure to direct the exhaust gas outside and
provide sufficient ventilation. Also, take care not to
direct the exhaust gas towards nearby plants or
animals, if any.
Engine exhaust gas contains carbon monoxide and
other substances that are harmful to humans.
Running the engine in a poorly ventilated place can
cause exhaust gas poisoning.

• œ Wear ear protector
Wear ear protector whenever entering
the engine room. Otherwise, the

may cause you to develop hearing
difficulty.
