TORQUE REACTION
When the Christie VC-RAD wrench is in operation the reaction arm rotates in the opposite direction to
the output square drive and must be allowed to rest squarely against a solid object or surface adjacent to
the bolt to be tightened. (See figure Below).
Ensure the Reaction Arm is NOT resting on a sloping or bevelled face.
SPECIAL NOTICE -
TIGHT FASTENERS
When tightening or releasing tight fasteners, the torque required to move the nut may be high enough to
keep the reaction locked in one position. This can cause the reaction plate to bend or cause gearbox
failure. To prevent failure, re-position the reaction plate after every two turns of the fastener, i.e operate
the tool briefly in the opposite direction.
