In a bristle blaster, the adapter (or accelerator bar) should be replaced when you notice:
- Excessive Wear – If the bar is visibly worn down, grooved, or has lost its original shape, it can reduce performance.
- Decreased Performance – If the tool isn’t cleaning or profiling the surface as effectively as before, the adapter might be worn out.
- Uneven Bristle Wear – If bristle belts are wearing out faster or unevenly, the adapter may not be guiding them properly.
- Visible Damage – Any cracks, dents, or deformation on the adapter mean it should be replaced to avoid further issues.
- Manufacturer Recommendation – Some manufacturers provide guidelines on when to replace the adapter based on usage hours or cycles.
Regularly inspecting the adapter ensures the tool operates efficiently and extends the life of your bristle belts.
