2. Position the tip of the chisel at the desired location.
3. Press the on/off switch.
Working at low temperatures:
The hammering mechanism works only when the power tool has reached a minimum operating
temperature. Bring the chisel into contact with the workpiece and allow the power tool to run
under no load until the required temperature is reached. If necessary, repeat this procedure until
the hammering mechanism begins to operate.
5.2.2 Switching off
1. Press the on/off switch.
2. Unplug the supply cord from the power outlet.
5.2.3 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 tip of the chisel toward the edge of the
workpiece, not toward a reinforcing bar.
▶ Begin with the chisel positioned at an angle of 70° to 80° to the concrete surface, with the tip of the chisel
pointing toward the edge of the workpiece. Break material away by subsequently increasing the angle to
approx. 90° as the chisel penetrates.
▶ 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.
6 Optional transport trolley
6.1 Transport
The transport trolley helps to ensure that the breaker can be transported safely.

• Place the power tool on the locating pin provided on the transport trolley and always secure it for
transport by closing the retaining bar.
• Push the chisels into the holders provided until they engage securely.
• Take care to use only safe transport routes.
• Do not park the transport trolley on an incline.
7 Care and maintenance
WARNING
Electric shock hazard! Attempting care and maintenance with the supply cord connected to a power outlet
can lead to severe injury and burns.
▶ Always unplug the supply cord before carrying out care and maintenance tasks.
Care
