In preparing for alignment, which should be done first after ensuring lockout/tagout has been applied?

The first step in preparing for alignment after ensuring that lockout/tagout procedures have been applied is to stabilize the machine base. This is crucial because a stable base ensures that the machine does not shift or move during the alignment process, which could lead to inaccurate measurements and potential misalignment. Stabilizing the base involves checking that all mounting bolts are tight, ensuring that any shims are properly adjusted, and confirming that any underlying supports are secure and level.

An unstable or improperly supported machine can introduce variables that affect alignment accuracy, which can lead to premature wear and tear on machinery components, misaligned shafts, and other operational problems. Therefore, the stability of the machine is foundational to the alignment process, making it the logical first step.

Other actions, such as measuring coupling spacing, inspecting parts for wear, or removing safety guards, are important but should follow the stabilization step to ensure that the alignment process begins on a solid foundation.
