First thing you might do is call their 800 number and ask them to send you a manual and catalog of accessories. Maybe the manual can be printed off the website, I don't know. One great accessory is the thingy that allows you to change bushings without taking the whole top off the loader, if that accessory is not already on your loader. Most 800B loaders were not equipped with this when first manufactured. A lot of stiffness can be eliminated by keeping the charging assembly clean, dry, and free of powder residue. Keeping the posts oiled helps also.
