4.1 Installing the reaction arm
Ensure the reaction arm and retaining ring are installed securely to hold the reaction arm in place. Make
sure the reaction arm is in contact with a solid reaction point before you operate the tool. When the tool
is in operation the reaction arm rotates in the opposite direction 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, see Figure 8.
WARNING: In use, this tool must be supported at all times in order to prevent unexpected release in the
event of a fastener or component failure!
4.2 Reactie arm height
Ensure the height of the socket is even with the height of the reaction arm as seen below in Figure 9A.
The height of the socket cannot be shorter or higher than the height of the reaction arm as seen below in
Figure 9B and 9C.
