The bolt has an M5 - 5mm head. You may have trouble finding the socket, but it's out there.
Remove the fan cage (4mm hex, left-hand thread). Rock the crank off with screwdriver. Install belt. Use screwdriver to hold it on the drive pully, turning the driven pully.
Use a 5/16" driver to remove the 2 long bottom bolts. (** might be 5MM ) You have to unscrew from the nut side, not the side that looks like you would use a straight blade screw driver. Also the shroud is easier to remove if you take off the brass fitting where the air hose connects. After you remove the shroud, you can remove the plastic cover on the pressure switch and there is an adjustment bolt that sticks out, has a 10mm head. There are + - indicators stamped near the bolt so you can tell which way increases max pressure and which way decreases.
Use the 5/16 driver to secure the head of the bolt, then back out the nut on the other end with a flat head screwdriver. You will need a wire hanger or a small and long punch to knock the bolt out of the other side.
