TROUBLESHOOTING
■ Precautions on Troubleshooting
When lifting up the engine, do not
allow the operators to stay under the
engine.
* Otherwise, falling down engine due to wire
break may result in serious personal injury.
The engine must be lifted only by an
operator who is qualified for a crane
and slinging works and also well
skilled.
* Otherwise, falling down engine due to
operational mishandling may cause serious
injury or damage to the devices.
To lift the generator set, consider the
mass of the generator set and that of
water remained in the generator set,
and use wire ropes, shackles, and
slings which are strong enough to
support the weight.
* Otherwise, falling down engine may cause
serious injury or damage to the devices.
* Check the contract specifications for engine dry
mass.
Use sling/hoisting tools in accordance
with their instruction manual.
* Otherwise, falling down engine may cause
serious injury or damage to the devices.
Use the hangers of the engine only for
lifting the engine unit.
* If you use them when the engine is assembled
with the generator and additional devices, the
hanger may not be able to endure the mass and
may break. If the engine falls, serious personnel
injury or damage to the devices will occur.
Before lifting the engine, drain fuel,
engine oil and coolant.
* Otherwise, falling down engine due to the
hanger break incapable of bearing the mass
may cause serious personnel injury or damage
to the devices.
Lift the slings while keeping the angle
formed by the slings attached to the
hangers within 60°.
* If the angle is too large, excessive weight will be
imposed on the hanger, which may cause
damage to the hanger.
Before inspecting and maintaining the
engine, read this Operation &
Maintenance Manual thoroughly to
understand the construction and the
required work to service the
corresponding part.In addition,
conduct the work after fully studying
the procedure.
* If you conduct the work without studying
enough, an accident or damage due to wrong
installation, or deterioration in the exhaust
properties may occur.
Do not take actions for items
indicated as "Contact your MHIET
dealer" in the measure column in the
Scheduled Maintenance.
* Otherwise, serious accident, environmental
pollution, or damage to the devices may occur.
Be sure to contact your MHIET dealer.
Do not disconnect the pipes
immediately after the engine is
stopped.
* Otherwise, you may get burned by hot engine
oil or coolant splashing out.
When lifting a part or tool, check its
weight and lift it slowly.
* If you lift it carelessly, you may hurt your back or
get injured by dropping the part.
Make sure that dripped oil, parts,
tools, or other things are not left on
the floor around the engine. Always
maintain cleanliness and tidiness.
* Otherwise, a tumbling accident may occur.
* Wear proper protective gears for the work.
Make sure that the tools to be used
are not damaged.
* Using a damaged tool or a wrong-size tool may
cause personal injury or damage to the devices.
Check and calibrate measurement
equipment periodically.
* Using uncalibrated measurement equipment
may cause damage to the devices or
performance degradation of them.
