LUKAS advanced blade geometry
Wider blade opening and optimized cutting geometry enable safer perimeter cuts and reduce the risk of blade twist, tool kickback or uncontrolled movement.

Intuitive dashboard
The E4 dashboard provides real-time visual feedback including roll warnings and stroke indicators to help prevent mid-cut stalls and support safe operation in low visibility.

Ergonomic handle
Two-component injection-moulded construction combines a rigid structural core with a soft-touch outer layer for secure handling and reduced fatigue. Certified 1,000 V protection allows safer work near EV and hybrid high-voltage systems.

Integrated light bar
Built-in high-intensity illumination highlights cutting points, hazards and tool position, improving decision-making and safety without external lighting.

Integrated on-tool charging
Direct-to-tool charging keeps the unit mission-ready by eliminating battery swaps and minimizing downtime during multi-call operations.
