A WARNING
ENGINE EXHAUST can kill.
■ Insufficient ventilation may lead to death due to lack of
oxygen or poisoning by exhaust gases.
* Do not use the machine in a place of poor ventilation or in a place
where exhaust gases stays.
* Do not use the machine indoors or in storehouse tunnel ship hold
tank etc. of poor ventilation.
* If it becomes necessary to use the machine in the above places the
exhaust pipe should he extended to a well ventilated place. In this
case use a ventilator to ensure proper ventilation.
* Do not direct the exhaust outlet to nearby pedestrians and houses.
A WARNING *
ELECTRIC SHOCK can kill.
В Do not touch the output terminals during operation to
prevent decease due to electric shock.
* Never touch the output terminals during operation. If your hands
or the machine are wet it will result in a death or serious injury.
* When a wiring work is required be sure to turn OFF the circuit
breaker and stop the machine.
* Keep the output terminal cover closed and the terminal bolts
tightened while the machine is running.
* A low voltage is generated even when the machine is in low speed
idle operation. Be sure to stop the machine completely.
В Do not touch the electrical parts in the machine during
operation as it may lead to death due to electric shock.
* Always close the control panel and tighten the fixing bolts before
operating the machine.
* Always close the side door and lock it before operating the
machine.
* When opening the control panel for voltage selection etc. turn
OFF the circuit breaker and stop the machine. _________________
A WARNING
ELECTRIC SHOCK by leak can kill.
В Improper grounding may lead to death due to electric shock.
* Be sure to execute the grounding of the machine and the load
according to the local rule.

flammable gases are accumulated which may be ignited and
exploded.
* When connecting a booster cable do not jumper the terminals (+
and —) Otherwise the flammable gases generated fiom the
battery may be ignited and exploded by sparks.
* For maintenance of the machine disconnect the ground cable on
the ground side.
Ш The battery acid is dilute sulfuric acid. Improper handling will
cause unexpected bums.
* When the battery acid gets on your clothes or skin wash it out
with a large volume of water immediately. If it gets in your eyes
wash with a large volume of water immediately and consult your
doctor.
t In the worst case it will put out your eyes.

engine and turn OFF the battery switch in advance. ______________
A CAUTION
Operator
ffl Do not operate the machine if operator is tired too much or
drinks some alcohol or take some drugs.
* Otherwise it may cause unexpected accidents or injury.
Ш During checking or maintenance be sure to put on suitable
clothes and protectors.
* Do not put on baggy clothes necklace etc. because they are easily
caught by projections which may cause injuries. _______________

A CAUTION
Noise
HI This machine generates large noise if the door is open.
Surrounding to large noise may cause hearing trouble.
* Close and lock the door during operation.
* If opening the door is necessary during operation be sure to put on
the ear protector. ________________________________________
A CAUTION
Connection to house wiring
В Before connecting this machine to any building's electrical
system a licensed electrician must install an isolation(transfer)
switch.
* Serious injury or death may result without this transfer switch.
A CAUTION
Transportation
И Do not lift the machine at the support hook or the ladder because
it is not strong enough for lifting and may cause a falling accident.
* When lifting the machine use the hanger located at the roof center.
* Keep out under the lifted machine.
Ш Do not lift or do not transport the machine during operation as it
may cause damage to the fan or serious trouble.
* When loading the machine on the truck or the like fix the machine
firmly by support hooks on the both side. _____________________

Indication/alarm lamp
(1) Preheat lamp
Wien the starter switch is set in the "PREHEAT" position
this lamp goes on.
In a little time this lamp goes off indicating that the machine
has been preheated to be ready for startup.
(2) Warning Lamps
This monitor indicates the following failures if any one of
them occurs.
CD High jacket water temperature
This lamp goes on when the water temperature rises
abnormally.
If this lamp goes on during operation the emergency stop
device immediately operates to shut down the engine
automatically.
© Oil pressure failure
If this machine is in normal operation this lamp stays off.
When the starter switch is turned to "RUN" position to start
the engine the lamp goes on and when the oil pressure rises
after startup it goes off.
If this lamp goes on during operation the emergency stop
device immediately operates to shut down the engine
automatically.
© Insufficient charge
This lamp goes on when the output voltage of the alternator
drops unusual value.
If this lamp goes on during operation the emergency stop
device immediately operates to shut down the engine
automatically.

2-4 Use of switches and controllers
Switches
(l)Starter switch
Functions:
CD Stop
This switch should be set in this position unless the machine
is in operation. The key can be inserted or pulled out in this
position.
© Run
This switch should be set in this position when the machine
is in operation.
© Start ■
This is the position to start the engine. When your hand is
released from the key after starting it is automatically set in
the position of“RUN”.
® Preheat
This is the position to start the engine when the air
temperature is low. Set the switch in this position until the
preheat lamp goes off and then set it in the start position.
(2) Speed control device
* Throttle lever
This lever is used to control the engine speed. Set the
lever at the "START/IDLING" position for startup or
warm up/cooling operation of the engine and at the
"RUN" position for constant speed operation of the
machine (at 50Hz or 60Hz).
* Frequency adjusting screw
This screw is used to adjust the frequency. With the
throttle lever set at the "RUN" position turn the screw
to the "HIGH" side to increase the frequency and to the
"LOW" side to decrease it.
14

(3) Circuit breaker
This is a main switch to supply power to a load. When the
load is shorted or in the state of overload it trips to protect
the generator against trouble.
[Note] :
Do not use this circuit breaker to turn ON/OFF the load to
prevent damage to the circuit breaker.
When it trips with over-current the handle of the breaker
stops between ON and OFF positions. This is what is called
the trip condition.
In this case push the handle down to the OFF position to
reset it or else it cannot be set in ON position.
Voltage regulator
(1) Voltage regulator
This regulator is used to control the output voltage. Turn the
regulator to clockwise to increase the voltage and counter
clockwise to decrease it. Adjust the voltage to the rated
voltage with this regulator.
