I have a 2010 Bone Hunter, which I understand is the same as the Cheetah. After I shoot a couple of arrows, I have a creaking sound coming from the idler wheel. If I draw it once but don't fire and draw it again, it doesn't make the noise the second or any subsequent draw until I actually shoot an arrow again. There is a lot of wax built up on the wheel and I am just wondering if the string is getting wedged onto the wheel causing the noise. If that is the case, how do I clean the extra wax off the wheel. Called Martin and he had no idea but said to send it in. Well, it is deer season so I am not too excited about sending my bow in to be checked.
