Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC)*1) , and other safety regulations. *1) ISO 4414: Pneumatic fluid power -- General rules relating to systems.
Safety Instructions Caution The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.

Caution ・ ・ ・ ・ ・ ・ Continuous blow air can be changed to pulse air without electrical wiring by connecting the pulse blow valve between air blow 2 port valve and nozzle of existing equipment. When an air gun and a pressure regulator are connected to OUT port, the back pressure of the OUT port will be high.

Be careful with the piping port. ・ For external pilot type, pulse air is only generated while pilot air is supplied.
6. Frequency adjustment Scale (0 to 8) Fig.6 Adjustment needle Fig.7 Adjustment needle Expansion Caution ・ ON time is shortened by rotating the ON time adjustment needle counterclockwise. ・ OFF time is shortened by rotating the OFF time adjustment needle counterclockwise. ・ Refer to the scale as a guideline for resetting. ON time ratio does not become 50% even when setting the adjustment needle for ON and OFF at the same value. ・ Small amount of leakage exists even when the needle is fully close.

7. Mounting Before connecting the valve, flush the piping of the upstream (supply pressure port side) and downstream (control equipment port side) to eliminate particles in the piping and foreign matter and scales generated during piping. 8. Environment Please contact SMC if the product is used where corrosive gas, chemicals and their solutions, water vapor, or seawater droplets exist, or temperature exceeds 50oC, or vibration occurs. 9.
