2. General Safety Instructions
Always observe the following safety precautions when operating power tools to prevent electric shock, fire, and serious injury.

4.3 Installing/Removing Drill Bits or Driver Bits
- Ensure the tool is switched off and the forward/reverse selector is in the center (locked) position to prevent accidental starting.
- Rotate the chuck collar counter-clockwise to open the chuck jaws.
- Insert the drill bit or driver bit fully into the chuck.
- Rotate the chuck collar clockwise to tighten the jaws securely around the bit. Hand-tighten firmly.

5. Operating Instructions
5.1 Powering On/Off and Speed Control
- The tool is powered on by pressing the trigger switch. The speed is variable and controlled by the amount of pressure applied to the trigger.
- To turn off the tool, release the trigger switch.
5.2 Forward/Reverse Rotation
- The forward/reverse selector switch is located above the trigger.
- Push the selector to the left for forward rotation (drilling/driving screws in).
- Push the selector to the right for reverse rotation (removing screws).
- For safety, place the selector in the center position to lock the trigger and prevent accidental starting when not in use or when changing bits.
5.3 Torque Adjustment
The Hilti SFC 18-A CPC features a torque adjustment collar located behind the chuck. Rotate this collar to select the desired torque setting. Lower numbers are for smaller screws or softer materials, while higher numbers provide more torque for larger screws or harder materials. The drill symbol typically indicates maximum torque for drilling applications.
Figure 2: Detail of the chuck and torque adjustment collar on the Hilti SFC 18-A CPC. The collar has numerical settings (e.g., 11, 13, 15) and a drill icon, allowing users to select appropriate torque for various tasks.
5.4 Drilling and Screwdriving Tips
- Always secure your workpiece to prevent movement.
- Apply steady, even pressure. Avoid excessive force, which can damage the bit or the workpiece.
- For drilling, start with a slow speed to create a pilot hole, then increase speed as needed.
- For screwdriving, select a torque setting appropriate for the screw size and material to prevent overtightening or stripping.
6. Maintenance
6.1 Cleaning
- Regularly clean the ventilation slots on the tool to prevent overheating. Use a dry brush or compressed air.
- Wipe the tool's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
