Compatible Dust
Extractor (Fig. G)

WARNING: Do not use dust extraction when cutting
metal. Swarf from metal cutting may be hot and may
spark which can melt vacuum hoses and may cause a
fire inside thevacuum.

WARNING: When using dust extraction, empty
vacuum before work begins and often during work.
Use care in disposing of dust. Materials in fine dust can
beexplosive.
Your tool is compatible with the DeWALT AirLock™
connection system. The AirLock™ allows for a fast, secure
connection between the AirLock™ connector
23
and your
tool's dust extraction port
8
.
1. Remove thebattery.
2. Ensure the collar on the AirLock™ connector is in the

on
collar and AirLock™ connector as shown for unlock and
lockpositions.
3. Push the AirLock™ connector onto the adapter
connectorpoint.
4. Rotate the collar to the lockedposition.
NOTE: The ball bearings inside collar lock into slot and
secure the connection.The power tool is now securely
connected to the dustextractor.
Mounting, Removing and Adjusting the
Dust Shroud (Fig. F)
NOTE: The dust shroud is only for tile/concrete and drywall
cutting applications to connect to a vacuum for dust
collecting. We do not recommend use of the shroud for
metal cuttingapplications.
1. Remove thebattery.
2. With the wheel properly installed, rotate the guard
12
all the wayforward.
3. Loosen the depth of cut wing nut
11
and fully extend
the shoe. Hand‑tighten the depth of cutknob.
4. Maneuver the upper guard and wheel into the dust
shroud assembly
9
and rotate tool to lock in place.
The front of the guard will rest against the stop inside
the assembly, and the back of the guard will catch the
release tab
21

To Adjust the Depth of Cut
1. Loosen the depth of cut wing nut and slide the shroud
up or down. Use the markings on the depth of cut gauge
to help determine proper depth. Adjust the cutting
depth to the thickness of the workpiece. Less than 1/4" of
the wheel should be visible below theworkpiece.
