Quick guide from the manual

This document provides essential operating instructions for the Hilti SF 14-A and SFH 14-A cordless drill/drivers. Always read the full documentation before initial operation to ensure safe and trouble-free handling.

Product Overview

The drill/driver features a keyless chuck, torque and drilling mode selector ring, side handle, control switch, forward/reverse selector with safety lock, and gear speed selection switch. The battery includes a charge state indicator.

Intended Use

The SF 14-A is designed for driving and removing screws and for drilling in steel, wood, and plastic. The SFH 14-A includes these functions plus hammer drilling in cellular concrete and masonry. Use only Hilti B14 series Li-ion batteries and C4/36 series chargers.

Preparations

• Charging: Ensure battery contacts are clean and dry before charging. Use an approved Hilti charger.
• Inserting/Removing Battery: Push the battery into the holder until it engages with an audible click. Press the release buttons to remove.
• Side Handle: Adjust to the desired position.
• Belt Hook: Can be fitted to the left or right side of the tool base using two screws.
• Accessory Tool: Set the forward/reverse switch to the middle position. Open the keyless chuck, insert the tool, and turn the chuck firmly by hand until tight and clicks are heard.

Operation

• Gear Selection: Adjust the two gear selector switches.
• Rotation: Set the forward/reverse switch to the desired direction. The switch is locked in the middle position.
• Switching On/Off: Press the control switch to start. Speed is controlled steplessly by varying the pressure. Release the switch to stop.
• Modes: Use the selector ring to choose between screwdriving, drilling, or hammer drilling (SFH 14-A only).

Care and Maintenance

Always remove the battery before maintenance. Clean air vents with a dry brush. Use a slightly damp cloth for the casing; do not use silicone-based cleaning agents. Check all parts for damage regularly.

Troubleshooting

If the tool does not work, check if the battery is fully inserted or needs charging. If the tool stops and all four LEDs blink, it may be overloaded or overheated; release the switch and allow the tool to cool down. If one LED flashes, the battery may be low or at an extreme temperature.
