SECTION 1 OF THIS MANUAL
Troubleshooting List...Blast Unit...Mechanical Malfunctions
Trouble Probable Cause Remedy
Excessive vibration -
usually indicates that the
blast wheel is out of
balance. This condition
will eventually cause
bearing failure in the
motor or bearing unit. Unevenly worn wheel.
Chipped, broken blades.
Replace wheel kit. Check
separator and ventilation system.
Chipped or broken blades will
permanently unbalance the blast
wheel and can cause damage to
other components. Change wheel
kit immediately.
Excessive noise - usually
indicates misaligned
components which
causes premature wear
and component failure. Improper clearances or
alignments between
rotating parts, usually the
control cage and the
blast wheel.
Loose bolts or
mis-alignment. Check alignment of control cage
and wheel. Allow sufficient
clearance between rotating parts.
Check bearing unit, belts, sheaves,
motor mounting, wheel housing
and any other associated parts to
be sure of alignment and that they
are firmly secured.
