supply cord is unplugged from the power outlet.

5.2.1
Chiseling
4
The chisel can be adjusted to 6 different positions (in 60° increments). This ensures that flat chisels
and shaped chisels can always be set to the optimum working position.
If inadequate pressure is applied, the chisel will jump around uncontrollably. Application of excessive
pressure will result in a loss of chiseling performance.
1. Plug the supply cord into the power outlet.
2. Bring the chisel into contact with the workpiece about 80 -100 mm (3¹⁄₈" - 4") from its edge.
