Safety Instructions Warning Do not disassemble, modify or repair other than instructed in this manual. Otherwise, an injury or failure can result. Disassembly prohibited Do not operate the product outside of the specifications. Do not use for flammable or harmful fluids. Fire, malfunction, or damage to the product can result.
2. Model Indication and How to Order *1) FKM and NBR have the same color. But, “F” mark is indicated on the inside of the pad when the plate is removed. For pad and ejector selection, refer to SMC’s website (http://www.smcworld.com) or Vacuum Equipment Model Selection in Best Pneumatics No.
3. Names of Parts of Product Mounting bracket Lock nut (Mounting with male thread) Lock screw Lock plate PD port Holder Silencer assembly Ejector body assembly Pad * Supply (P) port With ejector Lock pin Blanking plate assembly Without ejector *1) The product uses standard pad (rubber) of Vacuum Pad / ZP3E series.
4. Mounting and Installation (1) After the pad replacement, ensure the lock plate (1) is locked (see below). If the lock plate is not completely locked during operation, serious accidents such as falling of the pad or workpiece can occurdue to the vibration or load. (2) Make sure that the lock screw (2) of the lock plate (1) is properly tightened for safe operation.

(3) When connecting multiple pads to one ejector through the vacuum communication, other pads also cannot adsorb if incorrect adsorption occurs in one pad. Take safety measures so that the workpiece does not drop during transfer. (4) When using the male thread mounting type product, do not loosen the bottom nut shown in the figure below.
5. Air supply (1) Air is the applicable fluid for this product. Do not use fluid which includes chemicals, synthetic oils containing organic solvents, salt, or corrosive gases, etc. (2) If the air contains condensate or carbon powder, it may clog the ejector and cause deterioration of the performance or operation failure.
7. Piping 7.1 Piping connections to the PD Ports (1) PD port can be used in 3 ways: 1) Supply port of vacuum release air. 2) Connection port for the pressure sensor or pressure switch for vacuum for detecting the pressure in the pad.
7.2 Connection to supply (P) port (1) Allow a sufficient margin of tube length when piping, in order to prevent twisting, tensile, moment loads, vibration or impact being applied to the tubes and fittings. This can cause damage to the tube fittings and crushing, bursting or disconnection of tubing. (2) Prevent the connected tube from being rotated.

10. Repair 10.1 Maintenance and Repair Precautions (1) Perform regular maintenance to ensure safe and correct operation. (2) The vacuum pad is a consumable. Regular replacement is necessary. Replace the vacuum pad with a new one. The vacuum pad (rubber) may deteriorate. When the vacuum pad is used continuously, the following problems may occur.
10.2 Pad Replacement (1) Remove the lock screw. (2) Push the lever (on the ejector side) Note 1) of the lock plate to slide it to a position where it stops completely. (3) Pull out the pad assembly. (4) Pull out the stud assembly from the pad assembly.
10.3 Ejector Assembly Replacement NOTE Remaining part of the ejector assembly Ejector body Ejector assembly (1) Rotate the silencer assembly 90 degrees Silencer assembly counterclockwise. (2) Pull out the silencer assembly. (3) Pull out the ejector assembly. NOTE Ejector assembly consists of three resin parts.one of the parts may remain in the ejector body after the ejector assembly removal.
