This manual explains and illustrates general requirements for safety and cautions for safety.
Please read these safety requirements carefully and fully understand the contents before starting the
machine.
For your better recognition, according to the degree of potential danger harmful to a human body,
safety messages are classified into three hierarchical categories, namely, , , and
with a caution symbol － attached to each message.
When one of these messages is found, please take preventive measures for safety to carry out “SAFETY
OPERATION AND PROPER MAINTENANCE OF THE UNIT ”.
DANGER indicates an imminently hazardous situation which, if
not avoided, will result in death or serious injury. This signal word
is to be limited to the most extreme situations.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It may also be
used to alert against unsafe practices.
IMPORTANT indicates important caution messages for the per-
formance or durability of the unit, which has no concern to injury
or accident of or to a human body.
Follow warnings mentioned in this manual. This instruction manual does not describe all safety items.
We, therefore, advise you to pay special attention to all items (even though they may not be described in
the manual) for your safety.

1.2 Caution during Operation
 Never touch the output terminals during operation.
 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.
Never touch the output terminals and interior of control board
Hands off from rotating parts and belts

 Never work nearby hot portions of the machine while it
is running.
 Do not touch hot portions of the machine while inspecting the
machine when running.
 Such parts as engine, exhaust manifold, exhaust pipe, muffler,
and radiator are especially hot, so never touch those parts,
because it could cause scalding.
 Coolant water and engine oil are also very hot and dangerous
to touch. Avoid checking or refilling them while the unit is
running.
 Do not, under any circumstance, bring lit cigarettes or matches
near such oils as diesel fuel oil, and engine oil, etc.
They are extremely flammable and dangerous, so be careful
when handling.
 Refilling oils should be done in an outdoor well-ventilated
place.
 Refuel after stopping the engine, and never leave the fuel
nearby the machine. Do not spill. It may cause a fire. When it
is spilt, wipe it up completely.
 Do not supply fuel up to the fuel cap. And then the fuel may
get spilt when the unit is moved, transported and it is vibrating.
 Such parts as muffler and exhaust pipe can be extremely hot.
Remove twigs, dried leaves, dried grass and waste paper, etc.
from the exhaust outlet of the muffler.
 Keep a fire extinguisher available by the machine in case of
unexpected fire.
Do not touch hot parts

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.
 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.
