Measuring with Leg Extension (see figures F–H)
The leg extension 17 enables angle measurement when
the contact surface is shorter than the fold-out leg 1.
Place the base leg 4 and the leg extension flat on or
against the edges to be measured.
The reading of the angle w between base leg and fold-out
leg is indicated in the display. The required angle v be-
tween base leg and leg extension is calculated as follows:
v = 180° – w
The "Simple MTR" operating mode is used to determine
miter angles for miter cuts that are made with the blade
vertically perpendicular to the workpiece; in other words,
miter cuts for which the bevel setting is set at 0°. Such
applications include mitering baseboard and chair rail,
picture rails, door frames, staircase balusters, and pic-
ture frames.
The "Simple Miter" operating mode is activated by press-
ing the "MTR1" button. The displayed value is always
used for the calculation of the "MTR". If a saved value
is being displayed (indicator a flashes), the calculation
will be performed with the saved value regardless of the
position of the legs.
When workpieces are to be fitted into a corner (e.g. for
floor trimmings), measure the corner angle x° by applying
the fold-out leg and the base leg. For given angles (e.g.
picture frames), open the fold-out leg and the base leg
until the desired angle is indicated in the display.
