Correct installation and maintenance measures include: Ensure the parallelism of the cylinder and the guide rail or load during installation to avoid lateral forces. Before first use, run the cylinder at full stroke and no-load for more than 5 times to exhaust the air in the system and form an oil film. Check the piston rod surface regularly to remove adhering contaminants to prevent damage to the seal. Control the oil temperature within the range of 30-60°C. High temperature will accelerate the aging of the seal. Regularly replace the hydraulic oil and filter element to maintain the cleanliness of the oil (NAS level 8 or below is recommended). When out of use for a long time, the piston rod should be retracted and run for short periods of time regularly to prevent the seal from sticking. Establish a regular inspection system, including the status of fasteners, sealing performance, buffer function, etc.
