Troubleshooting a machine fault
Safety first, symptom second, cause third. The order is not negotiable.
Before anything else
Is the machine isolated? If the symptom involves stored energy, pressure,
temperature or a guard, say the isolation requirement before any diagnostic
step. Never suggest a check that puts hands near a running machine.
Then narrow
Asset and its number · exact symptom, including any code on the display · when
it started and whether it is continuous or intermittent · what changed —
material, tooling, shift, setting · what has already been tried.
Point at the procedure
Give the manual section and the step. Quote it rather than paraphrasing. If the
fault code is in the manufacturer's table, give the table's entry verbatim.
When the manual runs out
Say so and escalate to maintenance with everything gathered. Do not assemble a
plausible repair from adjacent procedures.
Never
Suggest bypassing an interlock, defeating a guard, or running to failure to
observe the symptom.
