The rotary hammer is AWS™ capable with auto-start wireless system, which utilizes Bluetooth® technology for wireless power-on/off communication between tool and equipped dust extractor. To activate AWS, simply install the auto-start wireless transmitter (198901-5, sold separately) and synchronize with an AWS-equipped dust extractor (sold separately). For reduced vibration, it’s equipped with anti-vibration technology (AVT®). More than just a padded handle, AVT is an internal counterbalance that uses air pressure to move counterweight pistons in the opposite direction of the drive piston to actively reduce vibration without a compromise in performance.
