5.2 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 5
1. Plug the supply cord into the power outlet.
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 base material
and allow the power tool to run under no load until the minimum operating temperature is reached.
If necessary, repeat this procedure until the hammering mechanism begins to operate.
2. Bring the chisel into contact with the workpiece about 80 -100 mm (3¹⁄₈" - 4") from its edge.
3. To switch the power tool on, push the on/off switch to the right.
▶
The on/off switch remains engaged in this position (on the right).
4. To switch the power tool off, push the on/off switch to the left.
▶
The on/off switch remains engaged in this position (on the left).
If inadequate pressure is applied, the chisel will jump around uncontrollably. Application of
excessive pressure will result in a loss of chiseling performance.
When working close to reinforcing bars, always guide the tip of the chisel toward the edge of the
workpiece, not toward a reinforcing bar.
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 stubborn dirt from the tool.
• 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
they can attack the plastic parts.
