Blade Height Scale

check with your customer before you saw to determine what actual finished thickness is required.
To use the quarter scale, look at the blade height indicator.Line up the horizontal red line on the indicator with
the nearest mark on the scale you want to use. Make a trim cut. When you return the carriage for a second cut,
lower the carriage to the next mark on the scale. This mark shows where the blade should be positioned to cut
a certain thickness of lumber, without having to measure on the inch scale.
Example: You want to cut 1" (25 mm) (4/4) random width boards from a log. Position the blade for the first cut.
Adjust the quarter scale so a 4/4 mark is aligned with the red line on the indicator. Make a trim cut. Return the
carriage for the second cut. Now, instead of having to measure down 1 1/8" (29 mm) on the inch scale, you can
simply lower the blade so the indicator is aligned with the next 4/4 mark on the quarter scale. Turn the log 90
degrees and repeat.
