Using these hose clips is easy. First, identify the hoses on your 2019 - 2022 Husqvarna TC 125 where you need to install the clips. Make sure the hoses are clean and dry. Then, simply place the clip around the hose and tighten it properly. Note that these clips are designed for AS3 Performance and OEM hoses, so don't use them on incompatible hoses. As for maintenance, since they're made of 18/8 marine - quality stainless steel, they're quite resistant to corrosion. But it's still a good idea to check them regularly for any signs of wear or damage. If you notice anything wrong, you can take advantage of the 12 - month warranty that comes with the product. Also, remember the photos are just for illustration, so the actual clips might vary slightly in appearance.
