5. Operation
Once the dust extractor is properly assembled and connected, you can begin your grinding task with significantly reduced dust.
- Power On Vacuum: Before starting the angle grinder, turn on your vacuum cleaner to ensure immediate dust extraction.
- Begin Grinding: Power on your angle grinder and proceed with your grinding work as usual. The dust extractor's brush base will contain the dust, directing it into the vacuum system.
- Edge Grinding: The dust extractor features a movable guard that can be adjusted to allow grinding closer to edges and walls. Carefully adjust this guard as needed for specific tasks.
- Monitor Dust Collection: Periodically check your vacuum cleaner's dust bag or canister and empty it as necessary to maintain optimal suction.
- Finish Work: Once grinding is complete, turn off the angle grinder first, then allow the vacuum to run for a few more seconds to clear any remaining dust from the hose and extractor.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your dust extractor.
- Cleaning: After each use, disconnect the dust extractor from the angle grinder and vacuum. Use a brush or compressed air to remove any accumulated dust from the interior and exterior surfaces, especially around the brush skirt and dust port.
- Inspect Brushes: Periodically inspect the brush skirt for wear or damage. Worn brushes can reduce dust collection efficiency. Replace if necessary.
- Check Connectors: Ensure the universal connectors and rubber vacuum adapter are free from debris and maintain a snug fit. Clean if necessary.
- Storage: Store the dust extractor in a clean, dry place away from direct sunlight and extreme temperatures.
