Blade Height Scale

The blade height indicator has two horizontal, red lines on both sides. Readings should be taken
with eyes level with the indicator, when the two red lines are in line. This will allow to avoid the
parallax error (different scale readings depending on the angle of vision).
The Scale
The horizontal red line on the blade height indicator shows how many centimeters the bottom of the
blade is above the bed of the mill. If you know the height of your blade at each cut, you can determine
the thickness of lumber you are sawing.
Example: You want to cut 25 mm random width boards from a log. Position the blade for the first cut.
Move the carriage to an even measurement on the scale. Make a trim cut. Return the carriage for the
second cut and lower it 29 mm below the original measurement. (The extra 3 mm allows for saw kerf
and shrinkage of the lumber.)
The yellow area on the scale identifies where the blade could encounter a side support or log clamp.
Check that these items are below the blade level before sawing.
The Quarter Scale
See Table 3-1.
The quarter scale contains four sets of marks. Each set represents a specific lum-
ber thickness. Saw kerf and shrinkage allowance are included, but actual board thickness will vary
slightly depending on blade thickness and tooth set.
To choose which scale to use, determine what finished thickness you want to end up with. The Grade
Hardwood Quarter Scale provides thicker finished boards usually required by commercial buyers.
The Standard Quarter Scale allows for kerf and shrinkage of finished boards suitable for most
custom applications. Always 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.Example: You want to cut 1" (25 mm) (4/4)
random width boards from a log. Position the blade for the first cut. 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.
