Page 5: Introduction
INTRODUCTION ® The Pneutorque 72mm series are air driven power tools designed for applying torque to threaded fasteners. An external pressure regulator (Lubro Control Unit) is needed; this allows the air pressure to be adjusted to determine the stall torque from the graph provided. There are models to cover torque capacities of 500 N∙m to 2000 N∙m. -

FEATURES AND FUNCTIONS Replaceable Drive Square All tools are fitted with a ¾” (19mm) or 1” (25mm) drive square that can easily be replaced. Trigger The trigger controls the flow of air. The more the trigger is pressed the more air flows into the tool. This allows for slow positioning of socket and reaction plate. -
