■ Follow the below procedures for cleaning the nozzle and the diffuser. Please carry out a maintenance with su ficient attention not to get injured. ① Loosen fastening bolts of exhaust side, then remove the bracket and the exhaust head. ② Remove the nozzles and the diffuser from ejector body. By removing the exhaust head, the nozzles and the diffuser are released. However, the 1st stage nozzle may remain in the ejector. Loosen fastening bolts and remove the bracket and the air supply head and a fitting as well if equipped, then push out the 1st stage nozzle from the air supply port. Be careful...

Vacuum Generator Series Vacuum Generator VVV ■ Method to change the vacuum port direction ■Follow the below procedures for changing vacuum port direction. ① Loosen fastening bolts of both port sides, then rotate the body to change the direction of vacuum ports. ② When changing the direction, be sure to align the Double-D seams of the heads and brackets when rotating the ejector body. ③ Fix the heads and brackets by tightening the fastening bolt with the tightening torque of 2.4 to 2.66Nm.

Common Safety Instructions for Vacuum Series Before selecting or using PISCO products, read the following instructions. Read the detailed instructions for individual series. 1. There is always a risk work pieces falling off during the vacuum operation. Please be sure to take into consideration safety measures against the falling of them or possible damage(s) caused by falling components. 2. Avoid supplying more than 14.5psi (0.1MPa) pressure constantly in a vacuum circuit. Since vacuum generators are not explosive-proof, there is a risk of damaging the products. 3. Pay attention to the dropping...
