Bolt cutters should be realigned when they are no longer cutting effectively or when the jaws appear misaligned. This can happen due to the bolts loosening during use, or if the jaws have been forced together or apart.
Here's a more detailed explanation:
Signs that your bolt cutters need realignment:
Poor cutting performance:
If the bolt cutters struggle to cut through materials they previously cut easily, it's a sign that the jaws may be misaligned or the cutting edges are dull.
Visible misalignment:
If the jaws don't close evenly, or there's a gap between them when they should be touching, they need to be adjusted.
Uneven wear:
If the cutting edges of the jaws show uneven wear, it indicates a misalignment problem.
When to check for and adjust:
Regularly:
It's a good practice to inspect the bolt cutters before each use, especially if you've used them for a while or for demanding tasks.
After heavy use:
If you've been cutting a lot of material, or if you've had to apply significant force, check the alignment afterward.
After dropping or impacting:
If the bolt cutters have been dropped or subjected to impact, they may have become misaligned
