RS2H Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations.

RS2H Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary.
2. Model selection The flow chart below shows the general procedure to select the optimum model in the RS2H series to suit the operating requirements. Operating conditions 1. Mass of transferred object: m (kg) 2. Transfer speed: v (m/min) Model selection example 3.

Lateral load and operating pressure Figure-2-2. Cylinder extended Warning (1) Precautions for model selection The compatibility of the product is the responsibility of the person who designs the pneumatic equipment or decides its specifications.
Caution (1) Do not allow pallets to collide while the lever is standing erect. If the next pallet collides while the lever is standing erect (after kinetic energy has been absorbed by the shock absorber), all the energy will be applied to the cylinder body. (2) When a load directly connected to the cylinder is stopped at an intermediate position Apply the operating range in the model selection (P.5) only in these cases where the stopper cylinder is used to stop pallets on a conveyor belt.
3-2. Piping Caution (1) Preparation before piping. Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove cutting chips, cutting oil and other debris from inside the pipe. (2) Wrapping of sealant tape. When connecting pipes and fittings, etc., be certain that cutting chips from the pipe threads and sealing material do not get inside the piping.
Caution (1) Do not apply rotational torque to the cylinder piston rod. Align the cylinder so that it is parallel to the working face of the pallet in order to prevent rotational torque acting on the cylinder piston rod. (2) Do not scratch or gouge the sliding part of the piston rod or guide rod. Scratches and gouges may damage the seals, causing air leakage or malfunction.
3-6. How to change piping port position If the piping port position needs to be changed for reasons of surrounding space, loosen the hexagon socket head plug, then mount in the new position. Hexagon socket head plug Tightening torque RS2H50・・・7~9Nm RS2H63, 80・・・12~14Nm Figure-5 3-7.
4. Operation Caution (1) For cylinders with locking mechanism, do not apply external force from the opposite side when the lever is locked. Lower the cylinder before adjusting the conveyor or moving the pallet. (2) For cylinders with locking mechanism, do not allow the pallet and roller to collide when the lever is locked.
Warning (1) Design the circuit to prevent sudden lurching of driven objects. When a cylinder is driven by an exhaust center type 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.
(3) Drain flushing Remove drainage from air filters regularly. (4) Removal of equipment, and supply/exhaust of compressed air When components are removed, first confirm that measures are in place to prevent work pieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function.
Warning Seals should be replaced by trained and experienced personnel. The person who does the replacement is responsible for safety once the cylinder is disassembled and reassembled. Caution Be careful not to cut hands and fingers on the edges of components when replacing seals. 6-3-1.
6-3-3. Grease application Caution Use SMC standard grease. Grease pack part numbers: GR-S-010 (Net weight: 10g), GR-S-020 (Net weight: 20g) 1) ①Piston seal Apply grease to the inner and outer circumferences lightly and evenly for easier mounting onto the piston. 2) ②Tube gasket Apply grease thinly to prevent the gasket from coming off.
6-4. Consumable parts 6-4-1. Replacement parts Please check the product number of the seal kit on our website. Caution Seals are not shipped in sealed packaging for storage, so they should be used within one year. 6-4-2. Seal storage Caution ・Pack seals in a sealed package such as a polyethylene bag and store in a box.
