SOUND-PROOF
DIESEL ENGINE GENERATOR

Introduction
Thank you for purchasing Shindaiwa Sound Proof Diesel Engine Generator.
This user manual was created to ensure the safe operation of this equipment.
Therefore, the manufacturer of this equipment strongly recommends that the user
follow the instructions herein, to avoid unnecessary accidents and repairs.
Please operate this equipment after thoroughly reviewing and understanding the
contents of this manual.
Please attach this manual, if the equipment will be sub-leased.
Please store this manual near the equipment for easy reference.
႑
႑႑
႑Following convention will be used throughout the manual to indicate
the degree of cautions.
Danger Can cause serious injuries or death.
Caution Can cause minor injuries or damage to the equipment or
other properties.
<Caution> Other types of caution
Even some of the items noted inᇹCautionᇺmay lead to serious injuries.
Please read all item and follow all the safety guidelines.
㻌
Danger : Suffocation from exhaust fume
Exhaust fume from the engine contains many elements harmful to
human. Do not operate this equipment in poorly ventilated area, such as
inside a room or in a tunnel.
Danger : Electric Shock
Do not insert metal objects (such as pin or wire) into plug-in receptacles.
Do not touch wiring or electric parts inside the equipment during
operation.
Ground the every grounding terminal to the earth as set in the manual. If
even one of all is unconnected by mistake or accident, it will be much
more dangerous for human than the NO-RELAY case, because leaking
current inevitably goes through the body.
Even when the ELCB in the load is grounded to the earth, be sure to
connect the terminal of bonnet in the equipment.
Be sure to check the resistor value of the equipment periodically so that
you can avoid the electric shock caused by electric leakage
Before connecting or disconnecting a load cable from output receptacles,
always turn the circuit breaker to OFF position.

1 Safety Guidelines
2
Before performing any equipment check or maintenance, stop the
engine, and remove the engine key. A person performing the
maintenance should always keep the key.
Danger : Injuries
Close all doors and place locks during operating this equipment, to avoid
injuries by unintentionally touching cooling fan and fan belt.
Caution : Suffocation from exhausting fume
Do not point the exhaust fume toward pedestrians or building.
Caution : Injuries to eye and skin
Battery fluid contains diluted sulfuric acid. Avoid contact with eyes, skin
or on clothing. If the acid comes in contact, especially with eyes, flush
with a lot of water, and contact your physician immediately.
Caution : Explosion
Do not use the equipment or charge the battery, in the case the battery
fluid level is lower than the LOWER level.
Battery may emit some combustible gas, so keep it away from fire and
sparks.
Caution : Fire
The equipment uses Diesel Oil as a fuel. When refueling, always stop
the engine and keep away from fire. Moreover, always wait until the
engine cools down before refueling.
Always wipe any drip of Diesel fuel or lubrication oil. Do not use this
equipment when a leak is found. Repair the equipment before use.
Temperature around muffler and exhaust can get extremely high. Keep
any inflammable items (such as fuel, gas, paint, etc.) away from the
equipment.
Always operate this equipment on flat surface and, at least 1 meter away
from any objects (wall, box, etc.).
Do not connect AC output to any indoor wiring.
Always wait until the equipment cools down, before placing any covering
materials for storage.
Caution : Burns
Never open the radiator cap during operation or just after engine stops
as hot vapor may belch out.
Do not touch the engine and muffler during operation and immediately
after stopping the equipment, for the temperature can reach extremely
high.
㻌
3
When checking engine oil or changing oil, always stop the engine, and
wait until the engine cools down. If you open either the oil gauge or the
oil plug during operation, hot oil may cause some injury.
Caution : Injuries
When lifting the equipment, always use a lift hook. Do not lift a handle,
for it may cause equipment to drop due to handle breaking off.
Always place the equipment on a flat and stable surface, to keep the
equipment from sliding.
When starting the engine, turn off the connected equipment and set the
circuit breaker to OFF position.
Do not move the equipment during operation.
When performing equipment check and maintenance, always stop the
engine.
Do not operate the equipment, if the equipment is being modified or if
the parts are removed.
