The Bosch HS143PK SDS-plus Bulldog Self-Sharpening Chisel Set is designed for efficient material removal in masonry applications. This 3-piece set includes chisels with specialized geometry that allows them to self-sharpen during use, extending their operational life and enhancing material removal rates compared to standard chisels.

The set comprises three distinct chisels:

• HS1472 Star-Point Chisel Twist: Features a unique star-point twist tip designed for greater productivity and reduced jamming. Its self-sharpening design ensures a wider material-removal footprint and prolonged life.
• HS1470 Viper Flat Chisel: Equipped with Power Ribs and Viper Teeth on its blade for faster material breakout. This chisel also benefits from a self-sharpening design for extended durability.
• HS1465 Tile Chisel: Engineered for quick tile removal, capable of removing material up to 40% faster than conventional tile chisels. It is ideal for removing tiles in one piece.

The chisels are provided in a compact tube for convenient storage and transport.

• Wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, gloves, and a dust mask, especially when working with concrete or tile.
• Ensure the chisel is correctly inserted and locked into the tool's chuck before operation.
• Keep hands and body clear of the working area during operation.
• Do not force the tool; allow the chisel and tool to do the work.

3. Configuració i instal·lació

These chisels are designed for use with SDS-plus rotary hammers or demolition hammers. Follow these steps to install a chisel:

1. Ensure your power tool is unplugged or its battery is removed.
2. Clean the shank of the chisel and apply a small amount of SDS-plus grease to the shank end. This helps reduce friction and wear.
3. Insert the chisel into the SDS-plus chuck of your rotary hammer. Push and twist the chisel until it clicks into place.
4. Pull on the chisel to ensure it is securely locked. There should be a small amount of play (movement) in the chuck, which is normal for SDS-plus systems.

4. Instruccions de funcionament

Once the chisel is securely installed, select the appropriate mode on your rotary hammer (typically 'hammer only' or 'chiseling' mode). Position the chisel at the desired angle and apply steady pressure. Allow the tool's hammering action to break the material.

4.1 Using the HS1472 Star-Point Chisel Twist

This chisel is effective for general breaking and demolition of concrete and masonry. Its star-point design helps to concentrate impact force, making it suitable for starting holes or breaking up larger sections. Angle the chisel to leverage the material and allow the twist design to clear debris.

4.2 Using the HS1470 Viper Flat Chisel

The Viper Flat Chisel is ideal for wider material removal, channeling, and shaping. Its Power Ribs and Viper Teeth facilitate aggressive material breakout. Use it for tasks requiring a broader impact area, such as removing larger sections of concrete or preparing surfaces.

4.3 Using the HS1465 Tile Chisel

Specifically designed for removing ceramic and other types of tiles. Position the chisel at a shallow angle beneath the tile, aiming to get under the adhesive layer. The design allows for quicker removal, often keeping tiles intact if desired.

5. Manteniment i emmagatzematge

Proper maintenance ensures the longevity and performance of your chisels.

• Neteja: After each use, clean the chisels to remove concrete dust and debris. A wire brush can be used for stubborn residue.
• Lubricació: Periodically apply SDS-plus grease to the shank of the chisels to maintain smooth operation and prevent wear in the tool's chuck.
• Inspecció: Regularly inspect chisels for signs of excessive wear, cracks, or damage. Replace any damaged chisels immediately to prevent injury or tool damage.
• Emmagatzematge: Store the chisels in their original compact tube or a suitable tool case to protect them from damage and corrosion. Keep them in a dry environment.

6. Solució De Problemes

If you encounter issues while using your Bosch SDS-plus chisels, consider the following:

• Chisel not engaging/slipping: Ensure the chisel shank is clean and properly inserted into the SDS-plus chuck until it locks. Apply SDS-plus grease if needed. Check if the tool is in the correct mode (hammering/chiseling).
• Reduced material removal: Verify that the chisel is not excessively worn. While these chisels are self-sharpening, extreme wear will reduce effectiveness. Ensure you are applying adequate, steady pressure and not forcing the tool.
• Vibració excessiva: This can indicate a worn chisel, an improperly seated chisel, or an issue with the power tool itself. Stop operation, inspect the chisel and tool, and re-seat the chisel.

For persistent issues, consult your power tool's instruction manual or contact Bosch customer support.
