5. Adjustment and Fixing of Chisel Angle
The chisel can be adjusted to 12 different position(in
30° increments). This ensures that flat chisels and
shaped chisels can always be set to optimum working
positions.
While pushing the selector forward as shown below, set
the desired angle in either clockwise or counterclock-
wise direction and let go of the Selaector.
Then the selector will be engaged with the body of the
Hammer preventing the rotation of the Chisel.
