ENSURE THAT POWER TO THE CONTROLLER IS
DISCONNECTED OR PROPER LOCK OUT/TAG OUT
PROCEDURES ARE BEING FOLLOWED
• Orient the Reaction Bar so that the recess above the spline on the
Reaction Bar is oriented towards the rear of the tool and any reaction
foot is oriented away from the tool anvil
• Install the Reaction Bar onto the splines of the gearbox ensuring that
the Reaction Bar is staying true to the splines.
• Install the Reaction Bar retaining ring/plate onto the end of the
Gearbox securing the Reaction Bar in place on the Gearbox.
FAILURE TO SECURE THE REACTION BAR PROPERLY CAN
RESULT IN SEVERE INJURY TO THE OPERATOR AND/OR
DAMAGE TO THE TOOL/APPLICATION
• Restore power/disengage Lock Out/Tag Out and prepare for use
THE TOOL HANDLE MUST NOT BE LOCATED AGAINST AN
OBJECT OR RESTRICTION DURING OPERATION OF THE TOOL
TO AVOID CREATION OF A PINCH POINT. AN OEM SOURCED
OR APPROVED REACTION BAR OR PROPER REACTION
ABSORPTION DEVICE MUST BE IN USE AND IN GOOD
CONDITION ANY TIME THE TOOL IS OPERATED. PROPER
TORQUE REACTION MANAGEMENT PRACTICES MUST BE
OBSERVED AT ALL TIMES. FAILURE TO UNDERSTAND AND
EMPLOY SAFE OPERATING TECHNIQUES CAN RESULT IN
TOOL DAMAGE, APPLICATION DAMAGE, SEVERE PERSONAL
INJURY, OR DEATH
When ready to begin tightening:
• Swivel the reaction bar (Slip Ring Equipped Models only) into position minimizing
or ideally eliminating any gap between the Reaction Bar and the Reaction
Surface of the application. On Fixed Gearcase models, ensure that reaction
absorption device is configured properly.
• Complete the tightening event.
Slip Ring Models
An optional feature (AEx4Bxxxxxxx models) on AcraDyne HT Series Nutrunners is a
Slip Ring that allows the Gearbox to rotate 360 degrees in either direction related to
the motor/handle assembly. This feature is useful in enabling the operator to position
the reaction bar against a reactive point of sufficient structure prior to commencing
tightening of the bolt.
Operators MUST ensure that no hands, body parts, or
other non-sufficiently structural elements are between the reaction bar and
reactive point when positioning the reaction bar. Care MUST be taken to
avoid tool start while positioning of the reaction bar is undertaken. Failure
to practice safe reaction bar handling can result in SEVERE injury to person
or damage to tool/application.
