Types of work
WARNING
Risk of electric shock! Severe injury and burns can result if any attempt is made to operate the tool without
an earth/ground conductor and ground fault circuit interrupter correctly connected.
▶ Irrespective of whether mains power or generator power is used, always make sure that an earth/ground
conductor and ground fault circuit interrupter are present in the power supply and that these are correctly
connected.
▶ Do not use the product unless these safety measures are in place and fully operational.
WARNING
A damaged supply cord presents a hazard! Do not touch the supply cord or extension cord if damaged
while working. Disconnect the supply cord plug from the power outlet.
▶ Check the appliance's supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged.
Full approval must be obtained from the site engineer or architect prior to beginning the work.
5.2.1
Chiseling
1. Plug the supply cord into the power outlet.
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.

Transport
The transport trolley helps to ensure that the breaker can be transported safely.
•
Take care to ensure that the transport trolley stands in a steady, secure position.
•
Place the power tool on the locating pin provided on the transport trolley and always secure it for
transport by closing the retaining bar.
