Operating Instructions for Hilti SFC 14-A / SFC 18-A Cordless Drill/Driver

Quick guide from the manual

This manual provides essential operating instructions for the Hilti SFC 14-A and SFC 18-A cordless drill/drivers. Always read these instructions before first use and keep them with the tool. Ensure the tool is switched off and the safety lock (forward/reverse switch in the middle position) is engaged before performing any maintenance, changing accessories, or transporting the tool.

Product overview

The drill/driver features a keyless chuck, a torque and drilling mode setting ring, a 2-speed gear selector switch, a forward/reverse selector switch with transport lock, a control switch with electronic speed control, a grip, and a lamp. The battery includes release buttons and a charge status display.

Before use

Ensure the battery is clean and dry before inserting it into the charger. To insert the battery, slide it into the tool until it clicks securely. To remove, press the release buttons and pull the battery out. The belt hook can be attached to either side of the tool for left- or right-handed use by securing it with the provided screws.

Operation

Forward/Reverse Rotation: Use the selector switch to choose the direction. When the switch is in the middle position, the control switch is locked (transport lock).

Speed Selection: Use the 2-speed gear switch to select the required speed range. Always operate large and heavy insert tools in the first gear to prevent damage.

Drilling and Screwdriving: Turn the torque/mode setting ring to the drilling symbol for drilling. For screwdriving, select the appropriate torque setting. Ensure the workpiece is secured with clamps or a vice.

Battery care and protection

The tool is equipped with an electronic protection system to prevent overloading and overheating. If the tool stops automatically, release the control switch and allow it to cool down. Check the charge status by pressing the battery release buttons; the LEDs will indicate the remaining charge. If the battery is too hot, it may be defective; allow it to cool down and contact Hilti Service if issues persist.

Care and maintenance

Keep the tool, especially grip surfaces, clean and free from oil and grease. Do not use cleaning agents containing silicone. Clean ventilation slots with a dry brush. Do not use spray, steam pressure cleaning equipment, or running water.
