[SML] SawStop

[Thomas Grabowski]

As we have a SawStop too and use a lot of Rosco Super Sat and Tough Prime, is there a difference with the colors as to the level of carbon infusion?  We are about two years in on the saw and have has 2 or so seemingly random triggers but have probably cut an amount of wood with Rosco paint on it.  Are there colors to watch out for?  Or is your message refereeing only to the Black color of the various Rosco Paints?

> Thank you for the brake cartridge you sent to us.  After we read the data

> cases include:
> 
>    - foil layers in laminated material such as countertop or flooring (or
>    printed circuit boards)
>    - foil backing on insulation board
>    - metallic paint on picture frames
>    - graphite layers in laminates
>    - carbon fiber material
>    - mirror-backing on acrylic plastic
>    - carbon-infused theater-set paint
>    - uncured glue layers in laminates
> To avoid this kind of problem going forward:
>  - avoid cutting the above materials in normal mode
>    - make sure that any glue layers have fully cured before cutting
> 
> If you are not sure whether a material poses a risk of activating the
> brake, you can place the saw in bypass mode and make a test cut or two.  If
> the material would have triggered the brake, the saw will blink its red LED
> until the blade is stopped to show that contact was detected. If the green
> LED stayed blinking with no red LED, you can cut safely normal mode. If the
> red LED started blinking, you?ll need to cut the material in bypass mode
> only.
