Using these hose clips is easy. First, make sure the hose and the connection area are clean. Then, place the clip around the hose at the right position. Tighten the clip properly, but don't over - tighten as it may damage the hose. When it comes to maintenance, since these clips are made of stainless steel, they are resistant to corrosion. However, it's still a good idea to check them regularly for any signs of wear or looseness. If you notice any issues, replace the clips right away. Keep them in a dry place when not in use. Remember, these clips are designed for specific applications, so make sure they are used on 1990 - 1993 Honda VFR 750 models and with AS3 Performance or OEM hoses.
