Precautions in Starting the Engine
1. Before starting the engine, please read this manual care-
fully and fully understand 'Danger,' 'Warning,' and
'Caution'. If you cannot fully understand it or have any
question, please contact us.
2. For safety reasons, attach "Warning" signs around
engines in operation to keep people other than workers
from accessing the engines. Let engine operators know
that they are responsible for the safety of the engine
room.
3. Only authorized people may start and operate engines.
Unauthorized people should not be allowed to handle
engines.
4. Do not get close moving or rotating parts while the engine
is in operation.
5. Do not touch the hot engine during operation since.
6. Exhaust gas is poisonous. Fully ventilate before starting
engine. If the space is enclosed, ensure that it is well
ventilated.
7. Keep vicinity of engine, ladders and stairways free of oil
and grease. Accidents caused by slipping can have
serious consequences.
Cautions for Inspection and Repair
1. Inspection and repair of engine should be performed only
when the engine is stopped.
2. If it is inevitable to perform inspection or repair on the
operating engine, do not get close to the rotating parts.
3. Use an engine oil drain container that is large enough to
prevent the overflow of engine oil while draining engine
oil.
4. Open the engine coolant cap after fully cooling the engine
to exchange or replenish coolant.
5. Fuel is highly flammable. Smoking or use of fire around
an engine may cause fire.
6. Mark and separately manage the containers for storing
coolant from beverage bottle for avoiding confusion. See
a doctor immediately in case of drinking coolant.
Immediately after stopping the engine or during
driving, be careful not to touch a part of turbocharger.
Otherwise, it can cause you to severe burns due to a
hot turbocharger. If you need to contact the turbo-
charger for maintenance, you should wait until the
temperature of the turbocharger will be lower suffi-
ciently.
Immediately after stopping the engine or during
driving, be careful not to touch a part of exhaust mani-
fold or heat screen. Otherwise, it can cause severe
burns to you due to the hot exhaust manifold or heat
screen. In particular, be careful not to touch the heat
screen installed on the exhaust manifold because it has
also a high temperature.
If you need an emergency engine stop, use an elec-
tronic emergency stop device installed on a generator
at first instead of mechanical emergency stop of
engine. It is difficult to operate a mechanical emer-
gency stop device mounted on a fuel pump and it can
cause serious burns to you by contact with the exhaust
manifold. The operator is requested to install the sepa-
rate cable for operating the mechanical emergency
stop. The engine maker won’t be responsible for an
accidents or injury arising without an installation of
separate auxiliary cable.
When accessories such as necklaces, rings, watches,
or gloves become stuck in rotating parts while the
engine is running, serious bodily injury may occur.
Do not exchange or disassemble a pipe or horse (from
the engine fuel circuit, engine oil circuit, coolant circuit,
or compressed air circuit) while the engine is running.
The leaked liquid may cause bodily injuries.
If the coolant cap is opened while the engine is still hot,
hot water will spurt out and may cause burns. Open the
engine coolant cap after fully cooling the engine.
Only refuel when the engine is stopped.
