Using your AS3 radiator guard is easy. First, gather all the hardware and fitting instructions that come with it. Follow the step - by - step instructions to mount the guard onto your bike's radiator. Make sure to tighten all the screws properly for a secure fit. When it comes to maintenance, simply clean the guard with a mild soap and water solution. Avoid using abrasive cleaners that could scratch the textured matt black finish. Regularly check the guard for any signs of damage or loose parts. If you notice anything wrong, contact us within the 12 - month warranty period for assistance. And remember, this guard is specifically designed for 2022 - 2024 Husqvarna Norden 901 and 2023 Husqvarna Norden 901 Expedition, so make sure your bike model matches before installation.
