Installing the reaction bar

reaction bar in place.
2. Attach the socket to the square drive. Make sure to insert the locking pin through the
socket and square drive according to the illustration.
Operating the tool with reaction bar
1. Attach the tool to the application.
2. WARNING Be aware that the reaction bar will turn in the opposite direction to
the tool.
By using the reverse lever, the tool can be operated in both clockwise and counter-clock-
wise directions.
3. Make sure the tool is placed in the correct position on the work surface as described in the
picture. The end surface of the reaction bar and the socket/nut must be aligned. Make sure
that the foot of the reaction bar hits the center of the nut that takes the reaction force.
4. WARNING Never put your hand on or close to the reaction bar while the tool is
being used.
Press the push button to start the tool.
5. Continue pressing the push button while running down the nut. With pneumatic tools you
can hear a sound, while the tool is running the nut down. When the sound decreases, re-
lease the push button to stop the tool. With electric tools the run down of the nut is con-
trolled by the Power Focus.
