Don't worry...I'm legit.  I have been posting on another forum also, and they were also concerned.  My name is Joe and I work for Barker & Herbert Analytical Laboratories in New Haven, IN.  We are a private forensic lab, and I was hired by an insurance company to determine the origin and cause of this fire.  My investigation so far has led me to an area of fire origin (at or near the parking brake).  Don't get me wrong, I am not saying operator error is not a factor.  I have not found an exemplar machine to exam, so I thought I would consult the people who own them.  My job also requires me to rule in or rule out potential manufacturing defects.

Some questions I would like to see answered:

How far do you have to pull up on the parking brake to illuminate the indicator light?
If 3 or 4 clicks, will a brake engaged at 1 or 2 clicks create enough friction to ignite nearby combustibles?
How close is the nearest combustible material to the parking brake?
Etc, etc!!!

Can anyone help??
