WARNING: Certain dust, such as oak or beech dust, is considered
carcinogenic, especially in connection with wood-treatmentadditives.
• Always use dustextraction.
• Provide for good ventilation of the workspace.
• It is recommended to wear an appropriaterespirator.

CAUTION: Never operate this saw for cutting wood unless the
dust bag or
DeWALT
dust extractor is in place. Wood dust may
create a breathinghazard.

Your mitre saw has a built-in dust port
16
that allows connection to
either a dust bag (33mm nozzles) or direct attachment to the
DeWALT
AirLock(DWV9000-XJ)
34
.
Observe the relevant regulations in your country for the materials to
beworked.

You may notice that all the dust will not come free from the bag. This will
not affect cutting performance but will reduce the saw's dust collection
efficiency. To restore your saw's dust collection efficiency, depress the
spring inside the dust bag when you are emptying it and tap it on the side
of the waste bin or dustreceptacle.
