Getting Started 13
Adjusting the blade exposure to the proper amount is a trial and error process.
You adjust the blade exposure visually, then perform a hand-held test cut on the
material you will be cutting. Evaluate the results, adjust the blade in or out, and
perform another hand-held test cut. Keep repeating this procedure until the depth
of cut permits easy weeding without cutting the material backing.
To set the blade exposure
1.
Hold the tool holder with the blade toward the ceiling. Turn the adjustment
cap clockwise (to extend) or counter clockwise (to retract) so that the blade
extends beyond the end of the tool holder approximately the thickness of
two sheets of paper. (Note: This is the correct setting for Scotchcal 220
material. Other materials may require more or less exposure.)
CAUTION: When performing the next step, do not press too hard on
the material. Too much pressure can damage the blade.
2.
Place a piece of the material you will be cutting on a flat surface and,
pressing gently, scribe a circle with the tool by hand.
3.
Weed the circle. If it weeds properly without cutting into the backing, the
blade exposure is correctly set for that material.
4.
If the material has not been cut all the way through, turn the adjustment cap
clockwise one or two hash marks to expose more blade. Go back to Step 2.
Repeat the procedure until the scribed circle weeds properly without cutting
the backing material.
5.
If the backing material has been cut, turn the adjustment cap counter
clockwise to decrease the blade exposure. Go back to Step 2. Repeat the
procedure until the backing material is no longer cut and the scribed circle
weeds properly without cutting the backing material.
