I have a Titan SF2656 sds drill, and the hammer action isn't working. The gearbox has been well greased. Any help on how to free it up, or where to find a manual will be much appreciated

There is supposed to be grease on the chuck end of SDS+ and SDS Max bits. Actually, you should put a little lightweight grease on the end of the bit every time you put one in your drill. If you, or noone who has ever used the drill, have ever done this, it is possible internal grease is leaking out of the drill and it should not. There are seals to prevent internal grease from getting out of the transmission and striker mechanisms. If you are loosing internal grease, these seals should be checked.
It is hard to understand what you are asking, however I have found that with the SDS drills one does NOT want to crowd them but just let the tool work with light pressure...
It uses grease to lube the gearbox. makita supply their own grease so you should be able to get a small tube from your local dealer. You don't have to use Makita grease though, just general grease should be fine. Not too thick and heavy, or too oily and light. I know that sounds a bit vague. Do you have other machines that you have grease for? SDS hammer drills, saws, any small power tool like that will use a similar type of grease.
Two drive systems are available on both the hammer drill and the rotary hammer models: 1. SDS (or Slotted Drive System) bits for hammer drills/rotary hammers allow the bit to slide in the chuck and enhance the hammering action of the tool. For most applications, these bits provide plenty of torque. 2. SDS Max bits are similar to SDS bits, but have larger shanks and come in larger sizes than SDS bits. These powerful bits are useful in industrial applications.
