1. Microcomputer control system-automatically detect pressure when it is crimping, with double safety protect. 2. The hydraulic unit incorporates an automatic retraction which returns the piston into it is starting position when the maximum operating pressure is reached. 3. The tool equipped with a fast approach towards the connecting material and a slow working stroke. 4. The crimping head can be smoothly turned by 360°around the longitudinal axis in order to gain better access to tight comers and other difficult working areas. 5. If a deviation from the set operation pressure or low battery charges is identified, an acoustic signal sounds and a red display flashes., Manufacturer: ZXZZAS
