Then, adjust the diameter of the compressor using the tool - less thumb adjuster according to your piston size. Place the compressor around the piston rings and gently guide the piston into the bore with the help of the gradual billet taper design. When using, avoid applying too much force to prevent damage to the piston or rings. For maintenance, keep the compressor clean after each use. Wipe it down with a dry cloth and store it in a dry place. If you notice any signs of wear or damage, it's a good idea to replace the compressor to ensure it continues to work effectively.
