I just bought an Elliptical. I didn't get the instruction book because it is an
exhibits on display and I got discount when I bought it. But now I can heard some noises when I use it and I don't know it is normal or not. This noise makes me a little bit unhappy. I don't know if I need to apply some lubricants . I haven't used lubricants to try yet because I found there are
some parts made by plastic material. I hope if someone here know and can tell me.
