representative should do daily operations on their own head.
Operators and maintemance representatives should take the safety of working place and work environment
into account.
It is necessary to think of the safety of working place and work environment for each task
Take enough safety training before the operation training. It is very dangerous to do operation training without
any safety training. Operation training must be paid attention to its safety.
i – 1 – 1 Meaning of Signs: Danger, Warning, Caution

i – 2 – 2 Danger of Electricity
Inside of this product, there is power-supplying section with high voltage separated by the
cover panel. Do not operate the product without the cover panel.
No one but trained qualified person should operate or inspect in the power transmission
sections.
Warning
Read with caution and pay attention to the notations on danger warning labels.
Do not remove or rub danger warning labels.
Confirm the positions of danger warning labels.
i – 2 – 3 Danger of High Heat
Warning
Since this product has parts that become hot during operation, there is the danger of burn
injury resulting from contact with them. What is more, there is also the danger of burn injury due to
remaining heat after the power supply is cut. Therefore, wait until the temperature of hot parts become
50oCand below.
i – 2 – 4 Danger of Rotor
Warning
Since this product has parts that rotate during operation, there is the danger of burn injury
resulting from contact with them. Though sometimes those parts can temporarily stop the rotation,
they will rotate again, and so do not work with them while driving.
i – 2 – 5 Danger of Compressed Air Circuit
Warning
Before replacing or cleaning parts, be sure to bleed compressed air remain inside of the
product untill the gauge indicates “0”. If you do not do this air-bleeding, there would be the
great danger of unexpected accident, such as shooting out of parts when they are being unscrewed.

•Connection to the inlet and outlet of compressed air should be made removable by using union and so on.
•Pressing the hexagonal fitting with screw wrench and so on, connect the air piping fittings to the body.
•When mounting any part such as an air filter on the fitting at the compressed air inlet or outlet port, support the
part to prevent excessive force from being applied to the product
•Be careful not to let the vibration of the air compressor transmit.
•If the temperature of compressed air on the inlet side is higher than 50oC, place an aftercooler after the air
compressor. Or, make the temperature of the place where the air compressor is installed lower than 50oC.
•If the air supply makes high pressure fluctuation (pulsation), take any countermeasures such as installing air
tank.
•Flash the piping sufficiently in order to avoid any foreign substances such as dust, sealing tape, liquid gasket,
etc. when piping before piping connection.Foreign substances in the piping can cause cooling failure or
drainage failure.
•Use pipes and fittings that have enough endurance against the operating pressure and temperature. And
connect it firmly to prevent air leakage.
•Provide bypass piping to make it possible to do maintenance without stopping the air compressor.
2 - 2 - 4 Drain Tube
•A polyurethane tube of 10mm external diameter is attached to the drain tube. The outlet end of the tube
is released to atmosphere. And let drain flow through the tube into a scupper and so on.
•Using the pressure of the compressed air, drain will be discharged periodically. Fix the outlet end of the
tube so as not to swing during discharge.
•Prevent the drain tube from riser piping.
•Prevent the drain tube from being folded or flatted. Since the drain tube is coming from the bottom of the
body, be careful to avoid the body from stomping over the tube during installation.
We recommend the bypass piping sets that
we are selling separately as accessories.
