Max. torque output CW 610N･ｍ CCW 700N･ｍModelsAI4201Special design by reinforced resin body and super light weight, only 1.0 kg!Small size that can enter even narrow places that did not enter until now.Achieves high power (maximum torque 700 N · m).The setting can be changed so that it can be operated with either left or right hand.Achieves high power with a big hammer mechanism that increases the impact power at one time despite the small size of the main unit.A rotary joint that prevents twisting of the hose.Achieves high power (maximum torque 922 N · m).Special design by reinforced resin body.Easily to change the setting to be operated with 2 way, either left or right hand.The reverse (left) rotation direction is set to a larger output than the positive (right) rotation so that loosening work can be performed efficiently.There is little vibration from twin hammers.A rotary joint that prevents twisting of the hose.Output adjustment dialOutput adjustment dialRotation direction switching leverRotation direction switching leverBig hammerOPTIONImpact socket（4NV-○○）P.224AI4201AI4220AIR IMPACT WRENCH, SHORT TYPEAIR IMPACT WRENCH※ Use a compressor with an air tank. The output of the compressor is recommended to be 0.75 kW (1 PS) or more.※ If the tightening torque is quite specied, we recommended to use a torque wrench together.※1The maximum air consumption (ntp) indicates the air consumption converted to the standard condition (0 ° C, 1 atm = 0.1MPa). The maximum air consumption (op) indicates the air consumption under actual operating conditions (20 ° C, 0.62MPa). ※2Adaptation bolt assumes wheel nut for car.Specication631849310869.5174191Max. torque output CW 732N･ｍ CCW 922N･ｍModelsAI4220Twin hammerCAUTION●Tightening torque may differ by conditions.12.7mm1/212.7mm1/2ModelsOutput drive dr.
