Festool Kapex KS 120 - Manual (Page 27)

11.
Measure the length of the fourth offcut. The accuracy
of this measurement is not critical, so a standard tape
measure or ruler will suffice.
12.
Measure the width of the fourth offcut at both ends (as
labeled “Right” and “Left”). These two measurements
are critical, so use the best method you can.

Calculating the Error
The equation for calculating the error is shown below,
however, the electronic version of this manual also
contains a built-in calculator. To use the calculator, enter
your measurements (in either mm or inches) in the boxes
and click on the “Calc Error” button. The calculated error
(angle) is displayed to the right of the button.

If the answer is a negative number (Right side wider
than Left side), then your saw is cutting too much to
the left of center.
►
If the answer is a positive number, your saw is cutting
too much to the right of center.
Adjusting the Saw
1.
Using the hex key stored on the cord reel, slightly
loosen the two adjusting screws located behind the
cord reel shown below.
2.
You may find it easier to move the entire saw head
instead of just the bevel plate. To move the entire saw
head, leave the bevel lock lever (see page 13) in the
locked position. To move just the bevel plate, move
the bevel lock lever to the unlocked position.
3.
Carefully adjust the bevel angle to account for the
error calculated previously.
4.
Retighten the two screws, and repeat the procedure to
verify the results.
5.
When the calibration is correct, torque the two screws
to 18 ft. lbs. (25 Nm).
