Safety: Remove the battery before disassembling the canister.

• Disassemble canister: Follow DeWalt instructions to separate the cyclone or internal baffles.
• Clear blockages: Use a brush or compressed air to remove compacted dust from cyclone cones and screens.
• Inspect pre-filter: Ensure the pre-filter is not collapsing into the airflow path. Replace if deformed.
• Reassemble carefully: Make sure all internal parts are correctly oriented and seated to maintain proper airflow.
