2. Installation and Usage
- If the load during operation changes, choose a cylinder with sufficient output force;
- In high temperature or corrosive environments, select cylinders with appropriate high-temperature or corrosion-resistant properties;
- In areas with high humidity, dust, water droplets, oil stains, or welding slag, take necessary protective measures for the cylinder;
- Before connecting the cylinder to the pipeline, clear out any debris inside the pipeline to prevent contaminants from entering the cylinder;
- The working medium should be filtered through a 40μm (or higher) filter before use;
- In low-temperature environments, take anti-freezing measures to prevent water in the system from freezing;
- Before use, conduct a trial run using air drive. Set the cushioning to minimum and gradually relax it to avoid excessive impact that may damage the cylinder;
- Avoid lateral loads during operation to ensure proper performance and prolong the cylinder's service life;
- If the cylinder is not used for an extended period, protect the surface from rust and cover the air inlet/outlet with dust caps.
