Упутство за употребу
Familiarize yourself with the controls and functions before beginning work.
1. Mode Selector Switch:
The GBH 3-28 E features a mode selector switch to choose between different operating modes:
- Drilling (Rotation only): For drilling in wood, metal, ceramics, and plastics without hammer action.
- Hammer Drilling (Rotation with Hammer Action): За бушење у бетону, зиданим зидовима и камену.
- Chiseling (Hammer Action only): For light chiseling work, such as removing tiles or breaking small sections of concrete.
Напомена: Always switch modes only when the tool is switched off to prevent damage to the gearbox.
2. Укључивање/искључивање:
- To switch on, press the On/Off switch.
- To switch off, release the On/Off switch.
- For continuous operation, press the On/Off switch and then press the lock-on button. To switch off, press the On/Off switch again.
3. Speed Preselection:
The rotary hammer drill features a speed preselection wheel. Adjust the speed according to the material and the size of the drill bit/chisel. Lower speeds are generally used for larger diameters and harder materials.
4. Working with the Tool:
- бушење: Apply moderate pressure. Let the tool do the work. Excessive pressure will not speed up drilling but can damage the drill bit and the tool.
- клесање: Hold the tool firmly with both hands. Guide the chisel along the desired line.
- Заштита од преоптерећења: The tool is equipped with an overload clutch. If the drill bit jams, the drive to the spindle is interrupted. Always hold the tool firmly with both hands to counteract the reaction forces.
