5.1.4 Removing the accessory tool 3
WARNING
Risk of injury! The accessory tool gets hot during use and may also have sharp edges.
▶ Wear protective gloves when changing the tool.
DANGER
Risk of fire! Risk of contact between the hot accessory tool and highly inflammable materials.
▶ Do not lay the hot accessory tool down on highly inflammable materials.
1. Pull the chuck back.
2. Remove the accessory tool.
5.2 Types of work
ATTENTION
Risk of damage by incorrect handling!
▶ Do not operate the switches for direction of rotation and/or function selection during operation.
Observe the safety instructions and warnings in this documentation and on the product.
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.
3. 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.
▶ When working close to reinforcing bars, always guide the tip of the chisel toward the edge of the
workpiece, not toward a reinforcing bar.
4. Rotate the chisel regularly to help ensure even wear and to promote the self-sharpening process.
5.2.2 Setting the chiseling power
▶
Press the power level selector switch.
▶ Chiseling power can be reduced to approx. 70% by pressing the power level selector switch.
Chiseling power can be adjusted only when the power tool is switched on and ready for use. To
reselect full chiseling power, press the chiseling power level selector switch again. Switching off
and then on again also causes the power tool to return to full chiseling power.
6 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
• Carefully remove any dirt that may be adhering to parts.
• Clean the air vents carefully with a dry brush.
• Use only a slightly damp cloth to clean the casing. Do not use cleaning agents containing silicone as
these may attack the plastic parts.
