Using your Shimano Altus FD - M310 front derailleur is easy. First, make sure it's properly installed on your bike frame with the right clamp size. Then, connect the derailleur cable to your shifter. When you want to change gears, just use your shifter to move the chain between the different chainrings. Remember to adjust the limit screws on the derailleur so that the chain doesn't fall off the chainrings. As for maintenance, regularly clean the derailleur with a mild bike cleaner and a soft brush. After cleaning, lubricate the moving parts to keep the shifting smooth. Check the cable tension every few rides, and if it seems loose, adjust it using the barrel adjuster on the derailleur or shifter. This will ensure that your derailleur works well for a long time.
