"Compound Mitre" Operating Mode
The "Compound MTR" operating mode is used for calcu-
lation of mitre and bevel angles when two workpieces with
multiple angles are to be precisely joined (e.g. for ceiling
strips).
Carry out the worksteps exactly in the given sequence.
"1. SPR": Storing the Spring Angle
SPR
The following possibilities are available for storing the
spring angle:
– Open the fold-out leg and the base leg until the required
spring angle is indicated in the display.
– When the spring angle is not known, measure it. For
this, place the workpiece to be measured between the
fold-out leg and the base leg.
When measuring particularly narrow or small work-
pieces with the measuring tool is not possible, use aux-
iliary aids such as a bevel angle or mitre rule, and then
adjust the angle on the measuring tool.
– Recall an already held value by briefly pressing the
"Recall / Hold" button 9.
Press button 11 to save the measured or recalled spring
angle for the compound mitre. "SPR" and the current angle
are indicated in the display.
When the angle is greater than 90° yet less than 180°
when pressing button 11, the "SPR" spring angle is auto-
matically converted as follows:
"SPR" = 180° – measured or set angle.
"2. CNR": Storing the Corner Angle
To measure the corner angle, place the fold-out leg and the
base leg flat against the walls, or set a known corner angle
on the measuring tool, or recall a held angle.
Press button 11 again to save the measured or recalled
corner angle for the compound mitre. "CNR" and the cur-
rent angle are indicated in the display.
"3. MTR": Determining the Mitre Angle
Press button 11 again. "MTR" and the calculated mitre angle
for the chop and mitre saw are indicated on the display.
