Piping
Do not remove the port seal until just before piping.
If the port seal is removed before ready to begin piping, foreign matters may enter from the piping
ports and cause a failure or malfunction.
Fully flush and clean the air pipe before use.
Open the exhaust port to the atmosphere.
The pressure cannot be properly controlled if the exhaust port is blocked with a plug.
Tighten the pipes with the appropriate tightening torque.
Observe the appropriate tightening torque to prevent air leakage and damage to the threads. To
prevent damage to the screw threads, first use your hands to lightly tighten the pipe and use a tool
to tighten the pipe further.
[Recommended tightening torque]
Do not apply high pressure suddenly when supplying the compressed air for the first time
after connecting the pipes.
When supplying compressed air for the first time after piping is complete, make sure that
there is no air leakage at the joints.
Apply leak detection agent to the joints in the piping using a brush to check for air leakage.
Seal material
Apply a seal tape or seal material to the screw threads leaving two or more threads at the pipe end
uncovered or uncoated. If the pipe end is fully covered or coated, a shred of seal tape or residue of seal
material may enter inside of the pipes or device and cause a failure.
When using a seal tape, wind it around the screw threads in the direction opposite from the screw
threads and press it down with your fingers to attach it firmly.
When using a liquid seal material, be careful not to apply it to the resin parts. It damages the resin parts
and causes a failure or malfunction. Also, do not apply it to the internal threads.
Seal material (solid or liquid)
