Be sure to read before handling. Refer top.0-33 to 0-36 for Safety Instructions and common precautions.

1 The exhaust port could become blocked by the clogging of thesilencer. Therefore, make sure to provide a safe design so as not tocause the system as a whole to malfunction.

1 The silencing effect could vary depending on the pneumatic circuitor the pressure that is used.

1 If the silencer body (case) is made of plastic and is BC sintered:To mount on a valve, hold the end of the body (the side that is notthreaded) with your fingers and screw it in. After some resistance isfelt, use a wrench that matches the wrench flats of the hexagonportion to tighten it an additional 1/4 turn. (If the silencer is not pro-vided with a hexagon portion, manually tighten it firmly.)

2 If the silencer body is made of metal (except the BC sintered style),tighten it at the torque given below.

3 Make sure not to apply a lateral load to the body during or after theinstallation.

Maintenance/Inspection

Caution1 Never disassemble the silencer. The silencing material is not

replaceable.2 If the exhaust speed drops and the system performance decreas-

es due to clogging, replace with a new silencer. Make sure to ver-ify the operating conditions of the actuator at least once a day.
