Take measures to prevent freezing, since moisture in circuits will be frozen under 5℃, and this may cause damage to seals and lead to malfunction. Refer to SMC’s “Air Cleaning Equipment” catalog for further details on compressed air quality.
- Page 13 9． Design circuitry to prevent sudden lurching of driven objects. When a cylinder is driven by an exhaust center directional control valve or when starting up after residual pressure is exhausted from the circuit, etc., the piston and its driven object will lurch at high speed if pressure is applied to one side of the cylinder because of the absence of air pressure inside the cylinder.

Page 14: Operating Environment
３） Mounting Caution ！ １． Make sure to connect the piston rod and the load so that their axial center and movement directions match. If they do not match, stress could be applied to the piston rod and the cylinder tube, causing the inner surface of the cylinder tube, the bushing, the piston rod surface, and the seals to wear and to become damaged. -
Page 15: Piping
4. Do not store cylinders in humid places. Humid environment should be avoided when storing cylinders. Before storing cylinder, be sure to retract its piston rod in a low humid place to avoid rust generation. ５） Piping Figure 1 is a basic circuit when operating a cylinder with air filter, regulator, solenoid valve and speed controller. -

３. Screwing of fitting When screwing the fitting into the port, tighten by the following appropriate torque. Table ５ Tighten torque of piping Tightening torque Port size N・m ２８～３０ Rc 1/2,NPT 1/2 ２８～３０ Rc3/4,NPT3/4 ６） Cushion ！ Warning 1) A deceleration circuit or shock absorber, etc., may be required. When a driven object is operated at high speeds or the load is heavy, a cylinder’s cushion will not be sufficient to absorb the shock. -
Page 17: Speed Control
3 . If the cushion valve is fully closed throughout operation, the piston may bounce at the stroke end, not move full stroke, or the cushion seal may be damaged due to excessive pressure. Therefore, do not use the cushion cover in such manner. -

2. Intermediate stops When intermediate stopping of a cylinder piston is performed with a 3 position closed center type directional control valve, it is difficult to achieve stopping positions as accurate and minute as with hydraulic pressure, due to the compressibility of air. -

Page 22: Replacement Procedure Of Seal
a. Seal kits should be packed in sealed up condition and stored. b. When removing a part of the seal kits, pack the remained items again so that the package condition will be restored to its former state as much as possible with care to protect them from foreign matters. Don’t store the remained items without sealing. -
