Installation
Installation Requirements
Selecting the torque reaction bar
The reaction bar is used to absorb the reaction torque of the tool during the tightening phase. It ensures the tightening
is done at the preselected torque. The reaction bar is a steel bar that should be shaped depending on the application
and the chosen tightening socket. Its weight can be reduced by cutting off any unnecessary metal. The contact sur-
face with the reaction bar must be able to withstand the reaction torque of the tool. The reaction bar is made accord-
ing to the location of this contact surface and the tightening torque. Each individual reaction bar is adapted to one
single tool. The reaction bars are not interchangeable from one tool to another.
Select the reaction bar type according to the tables above in this manual making sure that the tightening torque pro-
grammed does not exceed the maximum torque accepted by the reaction arm.
Desoutter shall not be held liable if the tool is used with any reaction bar other than a Desoutter-branded one.
For other models, contact the reaction arm supplier.

Selecting the contact area
To avoid output bearing and reaction bar overloads (TR), the contact point has to be within the shaded area (F) (see
Figure A). To determine the area (F), carry out a plan on a sheet of paper (see Figure B).

EN Installation
10/2019 11 / 20
1. Measure the distance (L) between the reaction bar grooved base (TR) and the centre of the nut in its final posi-
tion (DV).
2. Mark out this distance on the sheet of paper by using two points. Point A is the reaction bar base (TR), point B
being the centre of the nut in its final position (DV).
3. Refer to the table below to identify the minimum angle associated to the applicable tightening torque. Draw a
line at an angle α with the centre line (A-C).

Angle α (°) 21 30 35 38 41
Min. width: 86.5 mm
4. Draw a line (B-E) at right angles (90° to the centre line (A-C)) from point (B).
5. Starting at the same point (B), draw two lines at angles of +15° and -15° respectively from the line (B-E).
6. Highlight the F area by drawing the outlines.
7. Define the shape of the reaction bar (TR) so that the contact point (K) falls within the F area.
The ideal location of the contact point is on the B-E line. In Figure C, see the ideal contact line (LCI).
If the contact point K is located on an angle lower than α, the output bearing may be overloaded and the
reaction bar might be distorted. In Figure C, see the prohibited area (ZI).
If the contact point K is outside the +/-15 degrees, there is a risk of rapid wear of the socket and torque
accuracy for the selected torque is not guaranteed. In Figure C, see the area to avoid (ZE).
Bending the torque reaction arm
1. Heat the spot to red colour. It is recommended to concentrate the heat to the inside radius so that the external
width (W) remains over Wmin. (see Figure D and torque/angle table)
2. After bending, allow to cool slightly down to room temperature.
3. In order to lighten the reaction bar, it is recommended to cut it out as shown in Figure D.
After the bending, clean and degrease the surface where the safety pictogram is to be attached then attach
it.
Identify the surface that will be in contact with the bracket. In Figure D, see the contact surface.

Starting the tool
Fit the tool with a suitable socket.
Select the appropriate program on the controller.
Hold the tool by means of the handle, place the reaction bar on a suitable reaction point and apply to the fastener to
be tightened.
WARNING Risk of Injury
As the reaction force increases in proportion to the tightening torque, there is a risk of severe bodily injury of the
operator as a result of unexpected behavior of the tool.
►Make sure that the tool is in perfect working order and the controller is programmed correctly.
WARNING Risk of Burns
The motor may heat up during heavy duty cycles.
►Wear gloves.
