Basic Function Descriptions
Torque: Allows the operator to enter the target torque that the gun will seek when the trigger is pulled
and held.
Angle: If an angle setting is above “0” the gun will add this angle of rotation to a completed torque
operation using the maximum output of the unit.
Release Angle: After completing an operation, the gun will automatically run backwards the specied
angle to release windup from reaction torque. This will allow the operator to remove the tool without
loosening the fastener.
Torque and Angle Operation Caution: If the torque required to rotate the fastener through the selected
angle is unknown the torque may exceed the capacity of the tool in which case a failure warning will be
displayed: “Motor Stalled at Full Power.”
In order to determine if the tool is capable of meeting the requirement the following is suggested:
1. Tighten the fastener to the desired torque in Torque Mode.
2. Mark the position of the fastener.
3. With the tool still in Torque Mode set the tool to max output and measure how far the fastener
rotates.
4. If the fastener does not meet the angle requirement (with some margin) the torque to achieve the
angle is beyond the tools capacity and a larger tool should be used.
Note: This procedure will subject the fastener to max tool output torque. If unsure the fastener
can safely handle max torque do not perform this operation.
