6.3 Disengagement button for reaction pawl
The reaction pawl assures a one-way ratcheting mechanism. The reaction pawl absorbs
torsion and bending of the bolt, flexibility of the tool and movement of the reaction point.
Without the reaction pawl, the required torque may not reach the nut or the bolt and the
tightening speed will be decreased. The reaction pawl may cause the motor to stall at the
end of the tightening process.
After torquing, the tool is under tension and can be hard to remove. Disengage the
reaction pawl to release the tension and to remove the tool easily. Before you remove the
tool from the nut or bolt, complete the following instructions.
Procedure
1. Press and hold the start button on
the remote control until the set
pressure is reached.
2. Move the disengagement button to
position A.
3. Release the start button on the
remote control.
4. Remove the tool from the nut or the
bolt.
