Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Low or no suction
HighSymptoms: Cast dust not captured at the saw, weak airflow.
Root cause: Full or clogged filter bag / cartridge, a kinked or blocked hose, or a worn motor / impeller.
Vacuum will not auto-start with the saw
MediumSymptoms: Vac does not turn on when the cast saw runs.
Root cause: Auto-start current sensor or the saw-outlet connection.
Excess noise / overheating
MediumSymptoms: Loud operation, thermal cut-out during long use.
Root cause: Blocked cooling vents or a worn motor.
Filter seal / dust leak
LowSymptoms: Dust escaping the housing, filter not sealing.
Root cause: Worn filter gasket or lid seal.
