4.2 Placement of the Reaction Arm

When the Torque Multiplier is in operation, the reaction arm rotates in
the opposite direction to the output square and MUST be placed
squarely against a solid object or surface adjacent to the bolt to be
tightened.
ALWAYS select an anchor point (wall, another bolt) sufficient to
withstand torque reaction forces. Reaction torque equals output
torque.
