• Select the Correct Wrench Size — Identify the metric size of the flared nut on the fuel line, brake hose, or transmission line you need to service. Choose the corresponding wrench from the SEDY set (e.g., 9x11mm, 10x12mm, 13x14mm, 15x17mm).
• Position and Grip the Nut — Slide the correct end of the flare nut wrench over the nut, ensuring it fits snugly. The specialized design grips the flats of the nut, minimizing the risk of rounding it off, unlike standard open-end wrenches.
• Apply Steady Pressure — Using the offset handle for leverage, apply steady, controlled pressure to loosen or tighten the nut. For stubborn nuts, a gentle rocking motion may help. Avoid excessive force that could damage the fitting or the wrench.
• Store Properly After Use — Once finished, clean the wrenches to remove any grease or dirt. Place them back into the provided storage pouch to keep them organized and protected from corrosion, ensuring they are ready for your next automotive task.
