Using this flaring tool is easy. First, select the appropriate size for your copper tube. Place the tube in the tool and secure it. Then, use the reversible ratchet action to start the flaring process. It will make the job much easier compared to non - ratchet tools. When using, make sure the tube is clean and free of debris. Don't apply too much force suddenly as it may damage the tool or the tube. After use, wipe the tool clean with a dry cloth. Store it in a dry place to prevent rusting. If you notice any parts are worn out, replace them promptly to keep the tool working well.
