Installation and Use (General Purpose)

·When the load changes during operation, a cylinder with ample output force should be selected.

·Under high temperature or corrosive conditions, a corresponding high-temperature resistant or corrosion-resistant cylinder should be selected.

·In environments with high humidity,lots of dust,or presence of water droplets, oil dust, and welding slag,appropriate protective measures should be taken for the cylinder.

·Before the cylinder is connected to the pipeline, the dirt inside the pipeline must be cleared to prevent foreign objects from entering the cylinder.

·The medium used in the cylinder should be filtered through a filter element with a pore size smaller than 40um before use.

·In low-temperature environments, anti-freezing measures should be taken to prevent the water in the system from freezing.

·Before using the cylinder,it should be run under no load. Before running, the buffer should be minimized and gradually relaxed to avoid damaging the cylinder due to excessive impact.

·Avoid lateral loads. otherwise the piston rod will bend and deform and damage the rod end thread. The single acting type cannot be loaded during the return stroke.

·If the cylinder disassembled and not used for a long time ,attention should be paid to surface rust prevention dust-proof caps should be added to the intake and exhaust ports and special attention: the front and rear covers cannot be disassembled be the user independently.
