WARNING : EXHAUST GAS POISONING
Do not operate the generator in poorly ventilated areas such as indoors or tunnels, as
the exhaust gas of the engine contains substances that are harmful to human health.
Do not direct exhaust fumes at bystanders or buildings.
WARNING : ELECTRIC SHOCK
Do not operate the equipment with any doors or covers open.
Always turn all the breakers OFF, place the Power Switch in the OFF position and stop
the engine before connecting / disconnecting the load cable to the output terminal or
receptacle.
Close the output terminal cover before operating.
Do not insert a pin, wire or other metal object into the electrical outlet.
Do not touch the generator if the generator or casing or your body becomes wet during
operation.
Do not touch internal electric parts while the generator is operating.
Always turn the Power Switch to the OFF position and stop the engine, then close and
lock OPERATION PANEL DOOR before checking or maintaining the engine or any
equipment.
WARNING : INJURY
Close all doors and lock them during operation.
Do not open the check door when the Power Switch is in the ON position. It will cause
injury by rotating parts such as cooling fans and fan belt.
Always turn the Power Switch to the OFF position andstopthe engine, then close and lock
OPERATIONPANELDOOR before checking or maintaining the engineor anyequipment.
Always be sure to use Lifting Hook when lifting up the generator. Using other parts
when lifting up the generator could cause the result of falling.
Do not attempt to lift the equipment with any additional weight such as optional fuel
tanks or trailers.
No persons should ever be under a lifted generator.
Always be sure to check that the breakers on load side and switches for any
equipment using the generator are at OFF before turning the breaker to ON. Also be
sure to advise personnel on the load side that power will be turned on or off before
operating the breaker.
Do not modify the equipment and do not operate with parts removed.
CAUTION : EYE/SKIN INJURY
Wear rubber gloves and other protective wear to protect eyes, skin and clothing from
the battery fluid which contains diluted sulfuric acid. If the battery fluid contacts eyes or
skin, wash out immediately with a sufficient amount of clean water. Be sure to receive
medical treatment, especially if the fluid contacts the eyes.
CAUTION : EXPLOSION
Never use or recharge the battery if the fluid level is below the minimum level.
Do not create sparks or bring flame near the battery as it generates flammable gas.
1 Safety Guidelines

2
CAUTION : FIRE
Do not carry flammable items (such as fuel, gas and paint) or items that are highly
combustible near the generator as the muffler, exhaust gas and other parts become
extremely hot.
Position this generator 3 ft. (1 m) or more from walls or other hindrances, and on a
level surface.
Do not connect the generator output to indoor wiring.
This generator uses diesel fuel. Always be sure to stop the engine and not bring flames
close when inspecting fuel or refueling. Wait until the engine has cooled before
performing such procedures.
If fuel spills, always be sure to wipe and drain off spilled fuel.
Do not operate the equipment with liquid accumulated in the spill containment.
If fuel or oil is leaking, repair the leaking location before operating.
Always be sure to wipe up any spilled fuel or oil.
Allow the generator to cool before covering with the protective cover.
Never allow flame to come close to the generator.
Always make sure that the engine is stopped when working on piping.
After working on the piping, check that there is no fuel leakage.
Absolutely never inspect or perform maintenance to the equipment near fire or other
open flame.
CAUTION : ELECTRIC SHOCK
Do not sprinkle water on equipment or used where exposed to rain.
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after stopping the
engine as they are still extremely hot.
Do not open the radiator cap immediately after stopping the engine. Doing so will result
in hot steam gushing out.
Hot steam gushes out from the coolant sub-tank if the generator overheats. Do not
touch the coolant sub-tank.
Always be sure to stop the engine and allow the engine to cool when performing
inspection or maintenance of engine oil. Opening the oil level gauge or oil filler cap
during operation will result in hot oil gushing out.

3
CAUTION : INJURY
Always be sure to use Lifting Hook when lifting up the generator, and slowly lift it
straight up.
Personnel performing lifting work must wear protective gear such as helmets, safety
shoes and gloves.
Position the generator on a level stable surface so that it cannot slide or move in any
manner.
Before starting operation, always be sure to turn off all switches of equipment using the
generator and all breakers to OFF.
Do not move the generator during operation.
Do not operate the generator if it has been modified or any parts have been removed.
Securely fix the equipment with rope or similar item to avoid any unexpected move
when transporting by truck or other vehicle.
CAUTION : PROPERTY DAMAGE
Do not use the equipment for any improper applications. Improper usage can result in
an accident or malfunction.
If using this generator for medical equipment, check before use with the medical
equipment manufacturer, doctor, hospital or similar entity.
Check that the generator output setting, output terminal connection and load power
source are consistent.
Cable burnout can occur due to generated heat if the load current exceeds the
allowable current of the cable.
The voltage drop between cables is large if the cable is excessively long or thin,
resulting in decreased input voltage to equipment using the generator, thereby causing
decreased performance, faulty operation and malfunction.
