IMPORTANT NOTES:
Blast wheel blades must be replaced as a set. Replacing only some of the blades can cause imbalance of the
blast wheel.
Use a new central fixing bolt when mounting a new blast wheel.
Every time the control cage is replaced, the thread of the blast wheel fixing bolt should be checked. Make sure
that this bolt will be tightened correctly. In addition, absolute care must be taken to clean the thread from dust
and abrasive.
After each blast wheel repair work switch on the blast wheel motor for a short period (without feeding
abrasive) in order to find out whether the rotating parts turn freely and without vibration. After that, the blast
cleaning procedure can be continued.
