Table saw and mitre saw dust extraction

Treat saw extraction as a capture problem around the blade, rather than simply a hose attached somewhere on the cabinet. Table saws and cross-cut saws send dust into different areas. The correct arrangement must suit the exact machine and the cuts being made.

Table saws: check both capture areas

HSE's WD2 guidance describes extraction at the crown guard and below the bench, with an effective enclosure underneath. It advises reducing unnecessary flexible ducting, keeping connections secure and providing a way to check airflow. Changes to a guard or extraction port should be discussed with the manufacturer, rather than improvised from a photograph.

Our suggested preparation list is:

• Find the matching manual and identify every extraction connection.
• Record the specified airflow and whether it applies to an individual connection or the arrangement as a whole.
• Ask the supplier how both capture areas will receive the required performance.
• Check that hoses allow normal use of the guard and controls.
• Write down the commissioning checks and routine fault procedure.

Do not assume a cabinet hose also deals with dust above the table. Do not remove a guard to obtain a more convenient hose route.

Mitre and cross-cut saws: account for movement

HSE's WD3 guidance describes top-guard extraction and a hood behind a cross-cut saw, where dust is commonly thrown. Workpiece width and angled cuts affect the capture arrangement. A hose that moves with the saw must remain secure through the permitted travel.

A useful supplier enquiry includes the saw model, the normal workpiece dimensions, the range of angles and a sketch of the available space. Ask the maker which approved hood or extraction arrangement suits those conditions. A generic enclosure may interfere with machine movement, so compatibility needs checking.

Plan for use and maintenance

HSE's saw guidance covers RPE, cleaning, equipment maintenance and workplace examination requirements alongside the hood design. Read the full applicable sheet, rather than using this page as a complete risk assessment. If control equipment is damaged or the airflow check indicates a problem, stop and resolve it.

Use hose and port sizes to record the connections and the extraction planner to identify gaps in the specifications. A calculator cannot verify capture effectiveness at a working saw.
