Storage hopper.
Contaminated abrasive.
Abrasive feed and
abrasive control valve.
Wheel impeller, control
cage wear.
Drive belt.
Loss of consistent blast
pattern, “hot spot”.
Choked wheel. Check ammeter reading. Low
reading indicates insufficient
abrasive getting to wheel.
Check abrasive level.
Abrasive may contain substantial
percentage of fines and
contaminants. Check ventilation.
Check for obstructions in the
abrasive feed, i.e. feed spout,
abrasive control valve, and
separator screen.
May be worn. Replace wheel kit.
Check belt for proper tension,
alignment or wear.
Check blast pattern. Check the
blast wheel for proper seating with
the wheel hub.
Close abrasive valve and gradually
reopen. Check abrasive valve
operation. Check “over-amping”
blast wheel.
Excessive wear on blast
housing rebound
chamber/liners. Improper setting of
control cage. Abrasive is being misdirected into
internal components instead of

and readjust.
