8.3.2 Replace nutrunner (tool)
Do not attempt to replace a component of the tool - the tool must be replaced as a complete
assembly. The tool type identification can be found on the identification tag affixed to the tool
and on the System [PREAMP EEPROM DATA] screen.
WARNING:
DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM
COMPONENTS WITH POWER APPLIED.
1. Verify all System power is off.
2. Ensure that the three (3) homerun cables are marked for reconnection, then disconnect
them from the tool.
3. Ensure the spindle assembly is supported, and remove the two (2) bolts securing it to the
mounting plate.
WARNING: These two (2) bolts also secure the nutrunner, with the two (2) bolts
removed in the next step. Some tool models are very heavy. Use precautions when
disconnecting, removing, and installing these components.
4. The preamplifier is secured to the powerhead frame with two (2) screws. When possible,
it is more convenient to disconnect the preamp from the powerhead frame prior to
removing the nutrunner.
CAUTION: The preamp is also connected to the nutrunner, and this connection
must not be subject to stress or shock which could cause damage and result in
inaccurate System output. Do not allow any pull on the preamp cable.
5. To remove the nutrunner, first verify the preamplifier removal status (Step 4, above).
Ensure the nutrunner is supported, and remove the two (2) remaining bolts (two of the four
were removed in Step 3).
6. Follow all safety precautions to install an identical nutrunner/preamp assembly by
performing the removal procedure in reverse order.
8.3.3 Replace homerun cables
FEC INC. provides a spare set of homerun cables with each System.
1. Verify all System power is off.
2. Disconnect the damaged cable(s) from the nutrunner and the Axis unit, and replace with
the spare cable(s).
