Cylinder sections should be what before assembly?

Before assembling cylinder sections, it is essential to ensure they are cleaned out. This step is crucial because any debris, dust, or foreign materials present in the cylinder can compromise the integrity and functioning of the hydraulic system. Contaminants can lead to wear and tear on components, affect seals, and ultimately cause malfunction or failure of the system once it is in operation. Proper cleaning helps ensure smooth operation and longevity of the jacks, aligning with best practices in mechanical assembly and maintenance.

While lubrication, painting, and testing may play important roles in other aspects of maintenance and assembly, the primary focus prior to assembly is on removing contaminants to prevent operational issues once the cylinder is in use.
