Bought a pacemaster pro plus II recently. Loved the machine and for a
while I was trying to increase workout intensity by walking fast (3.4
mph) with an incline for 6-7%. Initially, it was not a problem, but I
noticed a creaking/cracking sound when I was walking in this mode.
Initially, it was sporadic and occassional, but it has since gotten
more frequent. In fact, when I was using one of the pre-programmed
variable intensity workouts where the speed and incline changes, I
noticed the sound when the treadmill was changing incline angle. I
have also tried changing incline when I am not standing on the
treadmill and I don't get this sound. When I walk fast without an
incline I don't get this sound also.
So the big question is: what is causing the sound? Is it potentially
dangerous enough that I should stop using it? Thanks in advance.
