Safety Instructions

Always read and follow all safety warnings to prevent electric shock, fire, or serious injury. Ensure the work area is clean and well-lit. Use appropriate personal protective equipment, including eye protection, hearing protection, and a dust mask. Never modify the tool or its accessories. When working near hidden electrical cables, hold the tool only by the insulated gripping surfaces.

Operation

To operate, insert a charged Hilti B 22 battery until it clicks into place. The tool features a variable speed trigger and a locking button for continuous operation. The depth gauge can be adjusted to ensure consistent screw seating, especially when using sealing washers. The rotation direction can be toggled using the forward/reverse switch, which also acts as a safety lock when in the center position.

Maintenance and Troubleshooting

Regularly clean the ventilation slots with a dry brush and wipe the housing with a slightly damp cloth. Do not use silicone-based cleaning agents. If the tool fails to start, check that the battery is fully engaged and charged. If the tool overheats or experiences electrical faults, stop use immediately and contact Hilti service. Always remove the battery before performing any cleaning or maintenance tasks.

Disposal

Hilti tools are largely made of recyclable materials. Do not dispose of electrical equipment or batteries in household waste. Return used batteries and tools to your local Hilti Store or authorized collection point for proper recycling.
