Using this Wera wrench set is a breeze. First, select the right torque setting between 2Nm and 12Nm according to your needs. You can turn it clockwise to tighten or counterclockwise to loosen. Hold the ergonomic handle firmly while using it to get the best results. When you're done with the task, just use the slip - over release mechanism to remove the wrench from the nut or bolt. Remember, don't try to force it beyond the set torque range to avoid damage. For maintenance, keep the set in the provided compact textile box when not in use. Wipe the wrenches with a clean, dry cloth after each use to keep them in good condition. Check the teeth regularly for any signs of wear and tear. If you notice any issues, it's best to get it checked by a professional.
