Use Reaction Bar

In operation, the reaction bar rotates in the opposite direc-
tion to the Output Square Drive and must be allowed to
rest squarely against a solid object or surface adjacent to
the bolt to be tightened. React should be on the end of the
reaction bar. When loosening attach the reaction bar on
the opposite side.

The supplied reaction bar has been designed to give an
ideal reaction point when used with a standard length
socket. In order to take into account a small difference in
the socket length, the reaction recording can have contact
at any point, in the shaded area of the illustration see Fig.
1-3: Safe Support Window, page 11.

If an extra long socket is used it may move the reaction
bar outside the safe reaction window.The standard reac-
tion bar may need to be extended to ensure it remains
wholly within the shaded area.

6.2 Limitation when using high torque /
soft screw joint
High torques and soft screw joints require a longer break
between screw connections, which is why we recommend
pre-tightening to increase the effectiveness.
