Here's the diagram:http://fish.shimano-eu.com/media/techdocs/content/cycle/EV/bikecomponents/ST/EV-ST-T400-S-1970_v1_m56577569830613258.pdf The lube in them tends to dry out and harden over time and needs to be flushed out with whatever is safe for the parts (cleaner/degreaser) and then relubed with some high quality lubricant. The spray stuff doesn't stay around long enough. Ask your local bike tech what he uses.I used saxophone key oil.

do you have the Shimano STI levers on a drop handle bar?
(if so then pull the brake lever hard to expose a hidden screw/allen key bolt)

Shimano's site doesn't show an MR486. Perhaps YOU could find something that matches your levers.
You can't make up for air or low oil in a hydraulic system by just tweaking the lever.

There is a barrel adjuster on the derailer, right where the cable comes in.
If you are having trouble getting to the easier gears then you need to tighten (usual problem -cable stretches). Pull out the barrel adjuster and unscrew it (turn CCW). Do this gradually until you get the shifting you want.
There are also two little adjusting screws on the face of the derailer that limit the travel of the derailer(keep it from jumping off the cogs, into the spokes or outside it). It is good to check these while you are working on it. The upper one is usually for the easiest gears, screw it in until you can no longer shift to the easiest, then unscrew it just a bit so that you can get in gear, but so the erailer can never go too far). If nothing happened, it is the other screw, so tighten that one.
Now do the other screw, tighten it until you can no longer shift to the smallest cog , then unscrew a bit, making sure you can shift to the smallest cog.
Hope that helps

SOURCE: Shimano CX200 mtb brake levers-
This is from a different model but it's old school, too, so it probably applies to yours.
"The Shimano 200GS is held to the bar with a hidden screw like old ten-speed brake levers. Remove the cable. Squeeze the brake lever. Look for the head of a screw or bolt in the gap exposed by the open lever/perch."
