5. Operating Instructions
This rotary hammer drill offers two primary operating modes: Electric Hammer and Electric Pick. Select the appropriate mode for your task using the mode selector switch.

Image: The mode selection switch on the top of the drill, showing the two settings: Electric Hammer and Electric Pick. This switch allows for quick adjustment between functions.
5.1 Electric Hammer Mode (Drilling and Hammering)
This mode is ideal for drilling into concrete, masonry, and other hard materials. It combines rotary action with a powerful hammering mechanism.
- Set the mode selector to the "Electric Hammer" icon (often depicted as a hammer and drill bit).
- Ensure the correct SDS drill bit for your material is securely inserted.
- Hold the drill firmly with both hands, maintaining a stable stance.
- Place the tip of the drill bit on the desired drilling point.
- Press the power switch to begin drilling. Apply steady, even pressure.

5.2 Electric Pick Mode (Hammering Only)
This mode provides hammering action without rotation, making it suitable for tasks like chipping, chiseling, and removing tiles or plaster.
- Set the mode selector to the "Electric Pick" icon (often depicted as a chisel).
- Insert an SDS chisel or point bit securely into the chuck.
- Hold the drill firmly and position the chisel bit against the material to be removed.
- Press the power switch to activate the hammering action.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your rotary hammer drill.
- Cleaning: After each use, wipe down the tool with a clean, dry cloth. Use compressed air to clear dust from ventilation openings. Do not use harsh chemicals or abrasive cleaners.
- Lubrication: The drill requires periodic lubrication. Refer to the lubricating oil injection port (as shown in the product overview diagram) for adding grease. Use the provided lubricating grease or a suitable equivalent.
- Carbon Brushes: The drill comes with spare carbon brushes. If the motor performance degrades or sparks excessively, the carbon brushes may need replacement. Consult a qualified technician if unsure.
- Chuck Maintenance: Keep the SDS chuck clean and free of debris. Apply a small amount of grease to the SDS bit shank before insertion to reduce wear.
- Storage: Store the drill in its plastic storage box in a dry, secure location, away from direct sunlight and extreme temperatures.

7. Troubleshooting
If you encounter issues with your rotary hammer drill, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Drill does not start. | No power supply; faulty power cord/plug; worn carbon brushes. | Check power outlet and connections. Inspect power cord for damage. Replace carbon brushes if worn. |
| Reduced hammering/drilling power. | Worn drill bit; insufficient lubrication; worn internal components. | Replace worn drill bit. Apply lubricating grease. If problem persists, seek professional service. |
| Overheating. | Blocked ventilation slots; continuous heavy use; motor overload. | Clear ventilation slots. Allow tool to cool down. Avoid excessive pressure during operation. |
| Bit not locking in chuck. | Debris in chuck; damaged chuck mechanism; incorrect bit type. | Clean chuck thoroughly. Ensure you are using SDS bits. If damaged, chuck may need replacement. |
If the problem persists after attempting these solutions, please contact customer support.
