Assembly and Operation
Battery Charging
Use only the chargers listed in the technical data. The battery is supplied partially charged. To ensure full performance, charge the battery completely before first use.
Changing the Tool
The drill spindle is locked when the on/off switch is not pressed. Open the keyless chuck by turning it in the direction of rotation until the tool can be inserted. Insert the tool and firmly tighten the chuck by hand.
Adjusting the Drill Head
The drill head can be locked in 5 different angle positions. Press the release button and swivel the tool head to the required position. Release the button to lock it in place. Always check that the head is locked before starting operation.
Operation
Use the rotational direction switch to change the direction of rotation. Press the on/off switch to start the tool. The speed can be regulated steplessly by varying the pressure on the on/off switch. The tool features a run-out brake to prevent the tool from continuing to rotate after the switch is released.
Maintenance and Cleaning
Remove the battery before any work on the tool (e.g., maintenance, tool change, transport, or storage). Keep the tool and ventilation slots clean for safe and efficient operation.
Safety
Always wear personal protective equipment, including eye protection. Do not operate the tool in explosive atmospheres. Keep children and bystanders away while operating. If the tool blocks, switch it off immediately to avoid high reaction torques.
