Exercise Equipment Repair Questions? Ask a Technician
Yes, if you have some mechanical skills you can service the machine yourself.
You will need to locate the cause of the tapping sound first.
You can then get replacement parts from http://www.sportsmith.net

Usually a tapping sound on these machines will be caused by a mechanical part which has loosened or become mis-shapen over time and is clashing; however since you are haring the sound as soon as you turn the machine on, this suggests it may be electro-mechanical.
First remove the cover, then listen carefully to different areas to try and narrow down where the sound is coming from.
If possible, attach a video here so I may see and hear.
