GAM 220 MF: "Simple Mitre" Operating Mode
The "Simple MTR" operating mode is used for calculation of the "MTR" cut-
ting angle when two workpieces with the same mitre shall together form any
outer angle x° smaller than 180° (e.g. for floor trimmings, staircase balus-
ters and picture frames).
The "Simple Mitre" operating mode is activated by pressing the "MTR1" but-
ton. 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.
The mitre angle "MTR", by which the two workpieces are to be shortened, is
calculated. For these mitre cuts, the saw blade is vertical to the workpiece
(the bevel angle is 0°).
Press button 14. The calculated horizontal mitre angle "MTR", which has to
be set on the chop and mitre saw, and the "MTR" indicator will be shown on
the display.
Press the "MTR1" button 14 to return from the "Simple Mitre" operating
mode to the "Angle Measurement" operating mode.
Briefly pressing the "ON/OFF" button will also take you back to the "Angle
Measurement" operating mode. However, any saved "HOLD" value will be
deleted when doing so.
Note: The calculated mitre angle "MTR" can only be taken over for chop and
mitre saws, for which the setting for vertical cuts is 0°. When the setting for
vertical cuts is 90°, the angle for the saw must be calculated as follows:
90° – indicated "MTR" angle = angle to be set on the saw.
GAM 220 MF: "Compound Mitre" Operating Mode
The "Compound MTR" operating mode is used for calculation of mitre and
bevel angles when two workpieces with multiple angles are to be precisely
joined (e.g. for ceiling strips).
The "Compound Mitre" operating mode is activated by pressing the "MTR2"
button. The displayed value of the leg positions is always used for the calcu-
lation of the angles. Any saved "HOLD" value will be deleted when the "Com-
pound Mitre" operating mode is ended.
