- 80Vmax cordless breaker powered by two 40Vmax XGT Li-Ion batteries in series.
- This cordless model, with its 80Vmax high voltage and BL motor, achieves power similar to corded models.
- Improvement in work efficiency on site achieved by the following:
• No need to prepare generator for on-site operation.
• Work can be performed without considering voltage drop as when using a cable reel. - Low Vibration / Anti-Vibration Technology (AVT)
• The anti-vibration housing structure and counterweight reduce vibration transmitted to the user's hands, and theimpact energy of 72.8 J makes the tool high-power and highly efficient, while reducing the load on the user duringcontinuous chipping operation. - Maintenance warning function
• An indicator lamp provides a warning when maintenance is required, such as grease-up, replacement of parts, etc.
