If you're looking to inflate your Majoni fenders, there are a few things you'll need to do first. First, locate the inflation valves on the fenders. There are typically two valves - one for each fender. Once you've found the valves, use an air compressor or pump to inflate the fenders to the desired pressure. Be sure not to overinflate the fenders, as this can cause them to burst. If you're not sure what pressure to inflate the fenders to, consult your boat's owner's manual for guidance.
