Insert the new cylinder gently into the cylinder seat. Make sure the cylinders are properly aligned and that the intake and outlet lines are connected to them. Then, use a wrench or appropriate tool to tighten the cylinder's bolts or screws to secure it to the seat.

Step 6: Test the cylinder

After the installation of the cylinder, reconnect the power supply to the air compressor and discharge some compressed air to test the normal operation of the cylinder. Make sure the cylinder does not leak and is working properly.

Step 7: Perform regular maintenance

In order to ensure that the cylinders of oil-free air compressors can operate consistently and efficiently, regular maintenance is very important. Check the operating condition of the cylinder regularly and replace lubricants and seals as needed. This will extend the life of the cylinder and ensure its efficient operation.

Please note that this is a general step-by-step guide and actual operation may vary depending on the air compressor model number. If you are not familiar with the operation, ask technical personnel to perform the operation or consult related services.
