 Notice that the voltage of several hundreds volt is applied to
the output terminal.
 When removing or connecting a connecting cable for changing
load, be sure to switch OFF the circuit breaker, remove the
starter key from the starter switch, then carry out a work. The
operator must keep the key during operation.
Neglecting the cautions mentioned above, and a third
party starting the machine during operation may cause
serious accidents such as electric shock.
 Keep hands off from the rotating portion or belts while running.
It could cause serious injuries if hands should be caught in.
 Do not, under any circumstance, open the radiator cap while
running or immediately after stopping operation. Otherwise
high temperature steam jets out and this could cause
scalding.

1.3 Cautions during Inspection and Maintenance
 Before starting inspection, switch off the circuit breaker of this
machine, remove the starter key from the starter switch, and
then hang a “Now Checking and under Maintenance” tag
where it can be easily seen. The checker must keep the key
during checking and maintenance.
 Remove the negative (–) side cable from the battery.
If the above procedure is neglected, and another person starts
operating the machine during check or maintenance, it could
cause serious injury.
 Be sure to stop the engine and remove the starter key
whenever the tension of the fan belt is to be adjusted.
 If the machine is running, it might catch the operator’s hand
into the fan belts, and this could cause a serious injury.
 Be sure to stop the engine and remove the starter key
whenever the tension of the fan belt is to be adjusted.
 If the machine is running, it might catch the operator’s hand
into the fan belts, and this could cause a serious injury.
 When cleaning dust accumulated in such devices as the
air-filter, etc., by blowing compressed air, wear safety glasses,
etc. to protect your eyes.

 It is recommended to use a lamp with safety guard fitted
where the site is dark. Operating the machine gropingly or by
relying on one’s intuition could cause unexpected accidents.
 Any lamps without safety guard are not recommended since
they can be broken and they could ignite flammables such as
fuel, etc.
 Be sure to stop the engine, and let the coolant water suffi-
ciently cool down before draining it.
 If the drain valve is opened before the coolant water is cooled
enough, hot water could jet out, and it could cause scalding.
 After stopping the engine, wait 10 to 20 minutes until the engine
oil cools off. Then check the level of the engine oil, or refill or
drain the oil.
 During operation or immediately after the engine stops, its oil
is extremely hot and pressurized, so it may jet out when the
cap is loosened. Be careful not to scald yourself from it.
 When washing the machine, cover the control panel, generator and its electric parts to prevent them
from being exposed to splashing water and avoid possible decrease in electrical insulation or other
troubles to the machine.
 Dust, sand and dirt accumulated inside control panel could cause malfunction or
trouble of the instruments. Clean them by blowing compressed air.
 Waste liquid from the machine contains harmful material. Do not discharge it onto the ground or into
the river, lake or sea. Such material will pollute the environment.
 Be sure to use a container to hold the waste liquid from the machine.
 Be sure to follow the designated regulations when disposing of oil, fuel, coolant (antifreeze), filter,
battery or other harmful materials.
