2. Important Safety Instructions
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools. Read and understand all instructions before use.
- Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug. Avoid body contact with earthed or grounded surfaces (e.g., pipes, radiators, ranges, refrigerators). Do not expose power tools to rain or wet conditions.
- Personal Safety: Always wear appropriate personal protective equipment (PPE), including eye protection (safety glasses), hearing protection, a dust mask, and heavy-duty gloves. Dress properly; avoid loose clothing or jewelry. Secure long hair.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Secure the workpiece with clamps or a vise.
- Maintenance: Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use.

4. Setup and Assembly
4.1 Attaching the Auxiliary Handle
- Loosen the auxiliary handle by rotating it counter-clockwise.
- Slide the handle over the front of the tool body to the desired position.
- Rotate the handle clockwise to tighten it securely. Ensure it is firmly fixed for safe operation.
4.2 Installing SDS+ Accessories (Drill Bits/Chisels)
- Clean the shank of the SDS+ accessory and apply a thin layer of grease (not supplied) to prevent wear.
- Pull back the chuck sleeve on the tool.
- Insert the SDS+ accessory into the chuck until it clicks into place.
- Release the chuck sleeve. Pull on the accessory to ensure it is securely locked. The SDS+ system allows for slight axial play, which is normal.
- To remove, pull back the chuck sleeve and pull out the accessory.
4.3 Connecting to Power
Ensure the tool's voltage rating matches your power supply (220V). Plug the power cord into a suitable grounded electrical outlet. If using an extension cord, ensure it is rated for outdoor use (if applicable) and has adequate gauge for the tool's power requirements.
5. Operating Instructions
5.1 Function Selection
The tool features a function selector switch to choose between three operating modes:
- Drilling (Rotation Only): For drilling in wood, metal, plastics, and for screwdriving. The hammer mechanism is disengaged.
- Hammer Drilling (Rotation with Hammering): For drilling in concrete, masonry, and stone. Both rotation and impact action are active.
- Chiseling (Hammering Only): For light demolition work, removing tiles, or channeling. Rotation is locked, and only the impact action is active.
To change the function, rotate the selector switch to the desired symbol. Always ensure the tool is switched off before changing the function.
5.2 Powering On/Off
To switch the tool on, press the ON/OFF trigger switch. To switch it off, release the trigger switch. For continuous operation, press the lock-on button (if present) while the trigger is pressed, then release the trigger. To switch off continuous operation, press and release the trigger again.
5.3 Speed Preselection
The tool features a variable speed preselection dial. Rotate the dial to adjust the maximum speed/impact rate. Lower settings are suitable for softer materials or when more control is required, while higher settings are for harder materials or faster work progress.
5.4 Working with the Tool
- Drilling: Apply steady, even pressure. Let the tool do the work. Do not apply excessive force, as this can overheat the motor or damage the drill bit.
- Hammer Drilling: For concrete and masonry, use the hammer drilling function. The pneumatic mechanism requires minimal pressure from the user.
- Chiseling: When chiseling, hold the tool firmly and guide it along the desired line. The auxiliary handle provides additional control.
- Depth Stop: Use the depth stop for precise drilling depths. Insert it into the auxiliary handle and adjust to the required depth.
6. Maintenance
Regular maintenance ensures optimal performance and extends the tool's lifespan.
- Cleaning: After each use, clean the tool, especially the ventilation slots, to prevent dust and debris buildup. Use a soft brush or compressed air. Do not use water or chemical cleaners.
- Chuck Maintenance: Keep the SDS+ chuck clean and lightly greased to ensure smooth accessory changes and prevent premature wear.
- Power Cord: Regularly inspect the power cord for any signs of damage (cuts, fraying). If damaged, have it replaced by a qualified technician.
- Storage: Store the tool in its carrying case in a dry, secure location, out of reach of children.
- Service: For any repairs or internal maintenance, contact an authorized Skil service center.
