Operation Guide

1. Pre-start checks

   • Confirm air supply pressure is within the specified range
   • Check for correct piping connections
   • Ensure operating temperature is within the allowable range
   • Verify secure installation of the cylinder
   • Confirm angle adjustment is correct

2. Basic operation

   • Forward rotation: Compressed air enters from one port, driving the vane to rotate
   • Reverse rotation: Compressed air enters from the other port, driving the vane to rotate in the opposite direction
   • Double acting cylinders provide power in both directions for bidirectional rotation

3. Pressure adjustment

   • Adjust operating air pressure according to application requirements
   • Higher air pressure results in greater cylinder output torque
   • Ensure air pressure does not exceed the maximum operating pressure of 0.7MPa
   • Select the appropriate minimum operating pressure based on bore size

4. Speed adjustment

   • Adjust rotation speed using speed controllers
   • Turn the speed controller knob clockwise to decrease speed
   • Turn the speed controller knob counterclockwise to increase speed
   • Ensure speed is within the specified range

5. Load considerations

   • Ensure the load does not exceed the cylinder's maximum allowable load
   • Avoid radial and thrust loads exceeding specified values
   • Consider the effect of inertial forces on the cylinder
   • Avoid sudden loading or unloading during rotation

Safety Precautions

1. Carefully read this user guide before operation
2. Ensure air supply pressure is within the specified range to avoid equipment damage or safety accidents due to excessive pressure
3. Cut off the air supply before installation and maintenance
4. Avoid use in environments with corrosive gases, dust, or high temperatures unless the equipment is specially treated
5. Do not exceed the rated load and operating frequency of the equipment
6. Regularly inspect equipment status to detect and address potential issues promptly
7. Immediately stop use and perform inspections if abnormal conditions are detected
8. Avoid placing fingers or other body parts within the cylinder's movement range
9. Use appropriate safety protection devices, such as protective covers or safety light curtains
10. Release internal pressure before disassembling the cylinder
11. Do not disassemble or modify the cylinder to avoid affecting safety performance
12. Use original accessories when replacing parts
