DECLARATION OF USE
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 of any unnecessary metal.
The contact surface with the reaction bar must
be able to withstand the reaction torque of the
tool. The reaction bar is made according 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.
Only a Desoutter-branded reaction bar is
to be used with ECP/ERP tools.
Desoutter shall not be held liable if the
tool is used with any other reaction bar.
The reaction bar must be applied on the
contact point before the tightening starts.
It will turn in the opposite direction of the
tightening accessory. (see Figure E, p.5)
Never put your hand on or close to the
reaction bar while the machine is being
used to avoid very serious injuries.
ADAPTING THE REACTION BAR
ANGLE CALCULATION
FIGURE A
To avoid overload of the output bearing and
reaction bar overload (TR), the contact point
should be within the shaded area (F). To
determine the area (F), it is necessary to carry
out a plan on a sheet of paper. (see Figure B,
p.5).
1. Measure the distance (L) between the
reaction bar grooved base (TR) and the centre
of the nut in its final position (DV).
2. Mark out this distance on the sheet of paper
using two points. Point A is the reaction bar
base (TR), point B the centre of the nut in its
final position (DV).
3. Refer to the table to identify the minimum
angle associated with the applicable
tightening torque. Draw a line at an angle α
with the centre line (A-C).

centre line (A-C)) from point (B).
