Setting the Angle using the Scale
To set an angle that is not preset, you need to use the scales. Just
loosen the handle, line the desired angle up with the 0 mark on the
Vernier side of the scale, and tighten the handle.

Using the Vernier Scale
Occasionally you will need to set the angle to the nearest 1/10 deg.
The Vernier scale lets you do that quickly and accurately.
Each black line represents 1/10 deg. and is used as the reference
point to set the number of tenths of a degree it represents. The use
of a Vernier scale is easier taught by example than trying to explain
how it works.
For example, to build a seven-sided picture frame you need an angle
of 25.7 deg.
1) Set the angle to 25 deg. Note we are using the left side of
the scale in the example.
2) Find the seven line on the left side of the Vernier scale.
3) Move the miter gauge until the very next degree line to the
left matches the seven line - so it looks like one continuous
line across the gap. Note how no two other lines match
exactly.
Tip
A common error in using a Vernier scale is lining up the Vernier scale
to the nearest degree mark instead of the next larger degree. You can
always double check your setting by looking at where the zero mark is
located. At 25.7 deg., the zero mark is about 3/4 the way to 26 deg.
