Operating the Wrench

Before you start the tightening or loosening operations, make sure of the following:
The square drive is installed correctly and is set to give the desired drive direction.
The reaction arm is installed correctly, with the correct orientation for the application.
The impact socket is the correct size for the application.
The impact socket is secured to the square drive with a pin and ring.
There are no hydraulic leaks. To test, cycle the tool 3–4 times to allow the pressure to build to the target value. Examine the system for hydraulic leaks.
For applications where the rear nut can rotate, make sure that a suitable backup wrench is available.
