Product Overview
The tool features a chuck, depth gauge, torque adjustment, and a forward/reverse switch. The battery status and tool malfunctions are indicated by LEDs on the Li-ion battery.
Intended Use
The product is a hand-held cordless screwdriver designed for fastening profile metal sheets, metal sheets, and sandwich panels in metal construction. It is designed for driving and removing self-drilling and self-tapping screws.
Operation
Battery: Use only Hilti Li-ion batteries of the B 22 series and Hilti battery chargers of the C4/36 series. Ensure contacts are clean and dry before insertion.

If the tool does not start, check if the battery is fully inserted and charged. If the tool or battery gets very hot, stop immediately and contact Hilti Service. If the screw is not driven correctly, adjust the depth gauge.
