Precautions Caution Series 25APrecautions Be sure to read before handling. Be sure to read “Handling Precautions for SMC Products” (M-E03-3) and “Instruction Manuals” before using. �� Change of material Series 25A- are copper- and zinc-free products, however, some parts including motors, cables, drivers for solenoid valves and electric actuators, and coils for auto switches, and connector pins and lead wires, whose material can not be changed, are made of copper. �� Particle generation (metallic contaminants) Usage of metal stoppers and/or shock absorbers on an air slide table produces metal-to-metal collision and contact, and may generate wear particles. Do not use metal stoppers and/or shock absorbers in an environment where wear particles are problem. The following models of air gripper may generate dust particles, as metal-to-metal collisions occur when fingers are fully closed. ・ MHZ2 ・ MHZL2 (Except -X5955) ・ MHF2 ・ MHY2 �� Static electricity Refrain from using the electrical equipments including detection switches (e.g., pressure switches and flow switches) in electrostatically-charged environments. Otherwise, they may cause the system to fail or to malfunction. �� Piping Usage of nylon tubing and polyurethane tubing in environments with a low dew point may affect dew points of ambient air and inside of piping. Use fluoropolymer tubing (Series TL) or stainless steel copper tubing (Supply it on your own) in environments with a low dew point. �� Chemical environment Refrain from using the products in such environments as exposed to chemicals. Otherwise, resin parts may deteriorate. If you want SMC to test the products for the effects of chemicals attached to them, send the products back to SMC after thoroughly cleaning them.
