Proper equipment function requires a properly aligned and balanced machine.  Allowing a machine to operate with an unbalance condition can result in bearing damage, cracks, loose components, and many other costly maintenance issues.  Loose debris can dislodge and impact the balance quality of a machine. Debris buildup on the impellers/blades, and other rotating parts can create unbalance conditions. Before balancing the machine it is very important that the rotating surfaces (blades, etc.) are cleaned of any debris. Removing buildup will help ensure that the machine can be properly balanced and remains in a balanced condition.
