That is why I mark them with my sharpy!
Always got to love those quick fixes,eh?
You know who many times I've had to readjust them just because someone didn't take the time to simply meg the motor.
It's amazing leveling problems can be fixed by just blowing out the carbon dust.
There was this one time when I got called to a job because of this and they sent over an"expert".
I let fiddle with it all day,he couldn't get anywhere.
He left and would be there again the next day.
Well,I grabbed my little portable air compressor,got there a little early and blew out the motor.
He shows up and everything is fine.
I just told him I didn't know what happen.
