More than likely the o rings are worn such that it won't seal. You can go to and download a breakdown for this tool and see all the parts needed to rebuild. Let me know if you need more assistance.

My makita hr3000c won't hammer what is the most likely reason

Beware that its an old type Makita where several parts are not are deliverable any more lubrication is the first reason leaking 2 seconds and if its leaking it becomes hot inside has lost its pneumatic working so the parts are become hot and will be worn soon and the person who works with leaking tools overload themselves rather than the work object.
Makita has sometimes problems in front of the impact bolts by its rotary hammers. to observate the part cilinder 331559-9 very carefull if its not torn nowhere and this applies also to part tool holder 323912-3 it must be smooth inside in front where the impact bolt is sealed

The big control levers off, but the small one only comes off once you have removed the screw and have it in the down position.
