General Power Tool Safety: Always keep the work area clean and well-lit. Do not operate in explosive atmospheres. Keep children and bystanders away. Ensure the power tool plug matches the outlet and avoid body contact with earthed surfaces. Use personal protective equipment, including eye protection, dust masks, and hearing protection.

Screwdriver Specific Safety: Hold the tool by insulated gripping surfaces when performing operations where the fastener may contact hidden wiring. Never use the depth gauge or chuck as a gripping area.

Operation

Before use, ensure the battery is fully charged and the forward/reverse switch is in the middle (safety lock) position. The tool features a depth gauge for precise screw seating and a lockbutton for sustained operation. To start, press the tool lightly against the working surface.

Maintenance and Troubleshooting

Regularly clean air vents with a dry brush and keep the tool free of oil and grease. If the tool fails to start, check if the battery is fully inserted or discharged. If the tool is overloaded, release the control switch and restart. For persistent issues, contact Hilti Service.
