download the basic teardown and re essembly video, you should use oil made for paintball(like goldcup) and lube up the internals. If you keep them maintained your marker should work well for a long time. Also, the first time you shoot it you may need to trim the spring so it will shoot at under the required velocity, someone at your field should be able to help with that if your uncertain. Good luckand welcome to paintball.
