Movement of the reaction arm
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!
6.1 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 2.
NOTE:
Improper reaction will void warranty and can cause premature tool failure.
6.2 Reaction arm height
Ensure the height of the socket is even with the height of the reaction arm as seen below in Figure 3A.
The height of the socket cannot be shorter or higher than the height of the reaction arm as seen below in
Figure 3B and 3C.
6.3 Reaction arm foot
Ensure the foot of the reaction arm aligns with the length of the nut as seen in Figure 4A. The length of the
foot cannot be shorter or longer than the nut as seen in Figure 4B and 4C.
