Working at low temperatures:
The hammering mechanism works only when the product has reached a minimum operating
temperature. Briefly position the product on the surface to be worked and run the product under
no load until the required temperature is reached. If necessary, repeat this procedure until the
hammering mechanism begins to operate.
6.3.2 Switching off
▶ Press the on/off switch.
6.3.3 Working with the power tool
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.
▶ Bring the chisel into contact with the workpiece about 80 -100 mm (3¹⁄₈" - 4") from its edge.
▶ When working close to reinforcing bars, always guide the chisel toward the edge of the workpiece, not
toward a reinforcing bar.
▶ Start with the chisel held at an angle of 90 ° to the concrete surface and face the chisel toward the edge
of the workpiece. Then change the angle to 70 ° to 80 ° and chisel the material away.
▶ Rotate the chisel regularly to help ensure even wear and to promote the self-sharpening process.
▶ If inadequate pressure is applied, the chisel will jump around uncontrollably. Application of excessive
pressure will result in a loss of chiseling performance.
