4. OPERATION
4.1. SINGLE CUT
NOTE: The outer scale is used to set the mitre saw setting angle to allow the placement of a single work piece to fit to an angle.
4.1.1. Measure the corner angle at the required location.
4.1.2. Read the angle on the outer scale (fi g 1).
4.1.3. Set the mitre saw to this angle and cut work piece to suit.
4.2. MITRE CUT
NOTE: The inner scale reading is used to set the mitre saw setting angle to achieve accurate mitred joints.
4.2.1. Measure the corner angle at the required location.
4.2.2. Read the angle on the inner scale (fi g 1).
4.2.3. Set the mitre saw to this angle and cut work pieces to suit.
4.3. CROWN MOULDING CUT
4.3.1. Place the mitre saw protractor onto the wall near to the ceiling and adjust to suit the inside or outside corner angle (fi g 3).
WARNING! If working at height take adequate safety precautions to prevent injury from falling.
4.3.2. Note the angle value on the inner scale (fi g 1).
4.3.3. Determine the spring angle (available on purchase of moulding) (fi g 2).
4.3.4. Refer to the Compound Cut Conversion Table, and locate the corresponding value from the inner scale on the mitre saw protractor,
with the row with the same “Mitre Cut” value.
4.3.5. Make a note of the “Mitre Angle” and the “Bevel Angle” from the corresponding row to suit the Crown angle of the work piece
(38º or 45º).
4.3.6. Set the mitre angle and the bevel angle on your compound mitre saw to suit.
