2. Setup
2.1 Unpacking and Initial Inspection
Carefully remove the tool and all accessories from the packaging. Inspect the tool for any damage that may have occurred during transit. Ensure all listed components are present.
2.2 Attaching the Side Handle
The side handle provides additional control and stability during operation. Loosen the handle clamp, slide the handle onto the tool's barrel, and rotate it to a comfortable position. Tighten the clamp securely.
2.3 Installing and Removing SDS-Plus Bits
- Installation: Clean the bit shank and apply a small amount of grease. Pull back the tool holder cover, insert the bit into the chuck until it locks, then release the cover. Pull the bit lightly to ensure it is securely seated.
- Removal: Pull back the tool holder cover and pull the bit out of the chuck.
3. Operation
3.1 Powering On/Off
To start the tool, press the trigger switch. To stop, release the trigger switch. For continuous operation, press the lock-on button while the trigger is depressed, then release the trigger. To stop from continuous operation, press the trigger switch fully, then release it.
3.2 Mode Selection
The HR2470 offers three operating modes, selected via the mode change lever:
- Rotation Only: For drilling in wood, metal, or plastic.
- Rotation with Hammering: For drilling in concrete, masonry, or stone.
- Hammering Only: For chiseling, chipping, or scaling operations.
Ensure the mode selector is fully engaged in the desired position before starting the tool.
3.3 Drilling Operation
Select "Rotation Only" mode. Apply light pressure and allow the tool to do the work. For deeper holes, periodically withdraw the bit to clear debris.
3.4 Hammer Drilling Operation
Select "Rotation with Hammering" mode. Hold the tool firmly with both hands. Apply moderate pressure and let the hammering action penetrate the material. Do not force the tool.
3.5 Chiseling Operation
Select "Hammering Only" mode. Insert the chisel bit. Position the chisel at the desired angle and apply steady pressure. The tool's hammering action will break up the material.
4. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your tool. Always disconnect the tool from the power source before performing any maintenance.
4.1 Cleaning
- Wipe the tool body with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Clean the ventilation openings regularly to prevent overheating.
- Remove dust and debris from the chuck and bit holder after each use.
4.2 Lubrication
The SDS-Plus chuck mechanism benefits from periodic lubrication. Apply a small amount of SDS-Plus grease to the bit shank before insertion to reduce wear and ensure smooth operation.
