9. TROUBLESHOOTING GUIDE (WHEEL TYPE BLAST MACHINES)

1. SYMPTOM: Problems with stability

If the machine uses a variable speed drive, check it for stability or bypass it with a conventional

motor starter.

The instability may be caused by flooding/choking the wheel or trying to flow more shot than the

capability of the wheel. Check for obstructions or restrictions or unnecessary bends in the flow path.
Worn blades or damaged control cages will not pass as much shot as new blades, therefore as blades
wear the maximum shot flow rate is reduced.
