limit screws may need adjustingTig

The derailleur's limit screws that prevent the chain from dropping off the inner or outer chainring may not be allowing enough range of movement. If you make an adjustment with the limit screw, do it ever so slightly and then take a test ride around the block. Too much travel will drop your chain. Here's a great guide from Park Tools:

If your cables are old, they may need replacing. Try lubricating them first. Check out this shifter problem remedy as well:

If it was right once, and nobody has fooled with the limit screws, I doubt they need adjusting.

My bet is new cables and housings, along with a good general cleaning of all the moving parts will do the job.

check the cablesTig

You may want to pull the cable out and check it for fraying or rust. Also check the cable housing ends to make sure the openings at each end are round, smooth, and have no burrs that could snag the cable. If everything is old or rusted, replace. Otherwise shoot some lube down the housings and replace the cable. You should replace the rear derailleur's cable and housings as well for preventative maintenance.

A little lubing of the pivoting surfaces of the derailleur wouldn't hurt either. Lube the shifters also:

If the derailleur is older you might want to check the spring to make sure that it hasn't rusted or worn out. Not very likely but it can happen. More likely that you just need to clean and lube the derailleur.
