Daily Check
Check the following items everyday, even when the
engine is not started.
• Devices and equipment outside the
scope of our supply are included in the
facility.
For the details, refer to such a
document as the specifications sheet
prepared by the generator supplier.
• For the devices and equipment outside
the scope of our supply, refer the
corresponding manual of the generator
and the supplier's operation manual.
Operational Environment - Check
Do not operate in an environment
below the lower limit of the ambient
temperature specified in the
specifications sheet.
* Otherwise, flue explosion may occur, which
causes serious personal injury or damage to the
devices.
* When operating in an environment below the
lower limit of the ambient temperature, it is
necessary to install an additional water heater.
Do not operate in an environment
above the upper limit of the ambient
temperature specified in the
specifications sheet.
* It may result in a violation of the law related to
the devices.
* It may cause damage to the engine due to
overheat or worsen exhaust values.
* When operating in an environment above the
upper limit of the ambient temperature, it is
necessary to reexamine the operating
conditions and operating time.
Keep away from fire, when working
with flammable substances such as
fuel, engine oil, coolant (LLC), grease,
rust preventive oil and anti-corrosive
agent.
* It may cause a fire.
Do not place flammable substances
such as fuel and engine oil around the
engine.
* It may cause a fire.
Make sure that there is no water
(especially, seawater or rain water)
seeped in the air intake and exhaust
ports.
* It may result in piston scuffing (contact of the
piston with the cylinder inner wall) and cause
damage to the devices.
Make sure that no foreign particles
get into the air inlet.
* They may cause damage to the turbocharger
and lead to serious problems in the engine.
Make sure that there is no
contamination of water into the fuel,
engine oil, air inlet and exhaust
systems and combustion chambers.
* It may cause flue explosion, deterioration in the
exhaust properties and damage to the devices.
Make sure that there is no clogging in
the air cleaner or pre-cleaner.
* Otherwise, the engine stopping device will stop
the engine suddenly, which may cause
deterioration in the exhaust gas properties.
Make sure that there is no clogging in
the air cleaner element or pre-cleaner
element.
* Excessive thermal load may cause piston
scuffing.
Before maintaining electrical
components, place the battery switch
to the OFF position or disconnect the
battery negative (-) terminal.
* Electric shock may result when electricity flows
through the circuit.
Be sure to operate the engine in an
environment of appropriate humidity.
* High humidity, inrush of rain water, or water
condensation in the combustion chamber may
cause falling off of valves or water hammering
and lead to damage to the devices.
