Operation with compressed air supply port opened
Do not operate the machine with service valves and relief
valve open unless air hoses and/or pipes are connected.
High-pressurized air blows out and its air pressure could
cause injury to the people nearby.
When the machine has to be unavoidably temporarily
operated with its port open, be sure to mount a silencer to
reduce noise and wear protective materials such as
earplugs to prevent damage to hearing.
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, radiator, oil cooler, air-end, pipe, separator receiver
tank, and discharging pipe are especially hot, so never touch
those parts, because it could cause serious burns.
Compressor oil, 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 engine oil and compressor 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 fill fuel oil up to the cap lever. When fuel tank is
filled up to the cap level, fuel oil will be overfilled due to
volume expansion caused by rise of ambient
temperature. Further, fuel will be possibly spilled from
fuel tank due to vibration caused during movement
and/or transportation of machine.
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.

1.3 Caution during Inspection and Maintenance
Remove the starter key from the starter switch before
starting inspection, and hang up 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.
When you refill the separator receiver tank with compressor
oil, stop the engine, and make sure that the pressure gauge
indicates 0MPa and there is no residual pressure in it, and
then gradually loosen the oil filler cap for refilling oil.
Note residual pressure in the separator receiver tank could
force both extremely hot compressed air and oil to jet out
and you may be scalded or seriously injured.

After stopping the engine, make sure that pressure gauge
indicates 0MPa. Even when the gauge shows 0MPa, open a
service valve and further do not fail to make sure that there is
no residual pressure in the air piping. Then start such a job
as repair and maintenance.
Residual air under pressure will blow off and severely injure
operator.
After stopping the engine, confirm that the pressure gauge
indicates 0MPa and there is no residual pressure in it, then
open the drain valve gradually to drain the compressor oil.
Note residual pressure in the separator receiver tank could
force both extremely hot compressed air and oil to jet out
and you may be scalded or seriously injured.
