Using these hose clips is easy. Just place the clip around the hose where you need it and tighten it properly. Make sure it's snug but don't over - tighten as it might damage the hose. When installing, keep an eye on the banded edges and smooth inners to ensure they are properly aligned with the hose. As for maintenance, since they are made of 18/8 marine - grade stainless steel, they can withstand most conditions. But it's a good idea to check them regularly for any signs of wear, especially if you're using your vehicle in harsh environments. If you notice any issues within the 12 - month warranty period, you can get them replaced. Remember, these clips are designed for specific KTM models from 1998 - 2002, so make sure they are the right fit for your bike.
