 ◎ given torque, built-in ACCU-TRK-type control automatically expire twisted bodies, precise control of torque: 
 Reach the predetermined tightening torque, torque control valve body within an instant turn off the motor immediately stops and the first batch will not turn, repeat the tightening torque to ensure the accuracy and reduce recoil, to save air consumption and improve productivity. 
 ◎ torque adjustment method: a small screw through the blade with adjustable torque clutch; 
 ◎ switch to a different torque spring, you can get more than standard torsion spring can be set to a wider range of torque can be set. Can also quickly snuff out the clutch to replace the entire (pre-set to different torque values.) 
 ◎ rotation / constant torque direction: both directions, L-or D-set torque (positive and negative to be twisted; individual types of positive torque setting, reverse variable torque). 
 ◎ Durability: Built O'Brien quality air motors (rotary power components), precision gear, special metal and heat-treated precision transmission parts and components, precision bearings, ensures high reliability, long-term durability. 
 ◎ Handle Type: Ergonomic design, soft plastic, non-slip, comfortable handle (straight shank), straight handle, grip, simple shape, easy to operate; easy to install auxiliary handles, hooks and other accessories; optional multi-function reaction arm. 
 ◎ tools start: under the pressure starts, the hand lever, pull the gun to start. 
 ◎ 1 / 4 "standard hex screwdriver folder mouth, insert pull, or quick. 
 ◎ vibration, noise and other parameters in full compliance with CE (European Union), ISO standards. 
 ◎ optional enhanced silencer casing (the standard tool has built muffler ???), can then 20-30%. 
 ◎ applications that require precise control of the application of tightening torque, is generally hard-wired; tighten the mounting screws, nuts, bolts, suitable for most industrial assembly use. 
 ◎ since parts of more than 90% of the Italian factory by their own production O'Brien, O'Brien will strictly control the quality and cost, high performance and low cost.
