Detailed Safety Instructions
Warning
1.When using double piloted valve type under a vibration, install the vacuum generaor placing the switchover valve (main valve) at a right angle to the direction of vibration
2.Tighten screws with appropriate tightening torque referring to the digital catalog. Improper tightening may cause an air leakage, a falling off of the product or damages to the product.
3.For the double-piloted valve type, the switchover valve is in the state of neutral when the supply of both pilot air to the switchover valve for vacuum generation is stopped, or at the beginning of use after shipment. When resupplying pilot air, be sure to input a signal to the pilot valve or manually operate to position the switching valve in the required state before using it
