Make a solution with a ratio of 30 gram (a handful) sodium carbonate to 1 liter hot water.2. Soak the dust filters in the solution for 30 to 60 minutes. The grease should be dissolved after 1 hour.3. If the dust filter is still clogged repeat this procedure from step 1.4. Rinse the dust filters with clean water to flush all grease residue away.5. Shake out all excess liquid by repeatedly swinging the filter to-and-fro in a centrifugal action.6. Then allow the filters to dry thoroughly.Note: Drying time of the dust filters can be up to 24h or more. Drying time can be shorter when being done in a well-ventilatedarea.Tip: To speed-up drying, allow the filter(s) to dry at 50°C max in a well ventilated room.C AUTION : UNDER NO CIRCUMSTANCES SHOULD WET FILTERS BE INSTALLED BACK INTO THE PROJEC-TOR.
