Press the button
MTR1
(14)
to return from the "simple mitre" operating
mode to the "standard measurement" operating mode.
Briefly
pressing the on/off button
(12)
will also take you back to the "stand-
ard measurement" operating mode. However, any saved
Hold
value will be
deleted when doing so.
Note:
The calculated mitre angle
MTR
can only be transferred for mitre
saws, for which the setting for vertical cuts is 0°. When the setting for ver-
tical cuts is 90°, the angle for the saw must be calculated as follows:
90° – displayed angle
MTR
= angle to be set for the saw.
GAM 220 MF: "Compound Mitre" Operating Mode
The "Compound mitre" ("Compound MTR") measurement is used to calcu-
late mitre and bevel angles when two workpieces with multiple angles (e.g.
crown mouldings) have to join precisely.
The "compound mitre" operating mode is activated by pressing the but-
ton
MTR2
(15)
. The displayed value of the leg positions is always used for
the calculation of the angles. Any saved
Hold
value will be deleted when the
"compound mitre" operating mode is ended.
Carry out the worksteps exactly in the given sequence.
1. SPR: Storing the spring angle
SPR
SPR
The spring angle can be saved as follows:
– Open the fold-out leg and base leg until the required spring angle is
shown on the display.
– Measure the spring angle if it is unknown. For this, place the workpiece to
be measured between the fold-out leg and the base leg.
When measuring particularly narrow or small workpieces with the meas-
uring tool is not possible, use auxiliary equipment such as a bevel angle or
mitre rule, and then adjust the angle on the measuring tool.
Press the
MTR2
(15)
button to store the measured spring angle for the com-
pound mitre.
SPR
and the current angle will appear on the display.
When the angle is greater than 90° yet less than 180° when pressing the but-
ton
MTR2
(15)
, the slope angle
SPR
is automatically converted as follows:
SPR
= 180° – measured or set angle.
2. CNR: Storing the corner angle
CNR
To measure the corner angle, place the fold-out and base legs flat against the
walls or set a known corner angle on the measuring tool.
Press the
MTR2
(15)
button again to store the measured corner angle for
the compound mitre.
CNR
and the current angle will appear on the display.
3. MTR: Calculating the mitre angle
MTR
Press the
MTR2
(15)
button again.
MTR
and the calculated mitre angle for
the mitre saw are indicated on the display. The mitre angle is used to define
the rotation of the saw table (
MTR
).
