Mounting The foot mounting cylinder has a hole in the foot to drive a pin into for accurate positioning and fixing. ！ C a u t i o n - Be careful not to scratch or damage the sliding surface of the rod while mounting it to the product or during maintenance. -
Page 12: Operating Environment
2-4. Operating envi ronment ！ W a r n i n g ・Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. ・Provide a protective cover if the product is used in direct sunlight. ・Do not operate in environments subject to heavy vibration and/or impact. - Page 13 [Use with air cylinder] ③ Use the pneumatic circuit which applies balance pressure to the both sides of the piston when locking. To prevent sudden extension when operation restarts or lock is released, control the cylinder to make balancing pressure applied to both sides of the piston so that the force generated in the operating direction of the piston due to load can be counteracted.

3. How to Use 3-1. Usage ① For intermediate stop, take stopping accuracy and overrun into consideration. As this is a mechanical lock, there will be a slight time difference for the stop signal and delay of the cylinder. The cylinder stroke during the delay is called overrun. The range between maximum and minimum overrun is referred to as overrun. -
