The tool type identification can be found on the identification tag affixed to the tool and on the System
[TOOL TYPE] preset value.
Tool Replacement Procedures
1. Verify all System power is off.
2. Ensure that the homerun cable is marked for reconnection, then disconnect it from the tool.
3. Ensure the spindle assembly and nutrunner are supported, and remove the (3) bolts securing
them to the mounting plate.
WARNING: These bolts also secure the nutrunner. Some tool models are very heavy. Use
precautions when disconnecting, removing, and installing these components.
4. Follow all safety precautions to install an identical nutrunner assembly by performing the removal
procedure in reverse order.
