5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
EDGE GRINDING WITH GRINDING WHEELS
CAUTION: Wheels used for cutting and edge grinding may break
if they bend or twist while the tool is being used to do cut-off work
or deep grinding. To reduce the risk of serious injury, limit the use of
these wheels with a standard type 27 guard to shallow cutting and
notching (less than 1/2" in depth). The open side of the guard must
be positioned away from the operator. For deeper cutting with a type
1 wheel, use a closed, type 1 guard. Type 1 guards are available at
extra cost from your local dealer or authorized service center.
1. Allow the tool to reach full speed before touching the tool to the
work surface.
2. Apply minimum pressure to work surface, to allow the tool to
operate at high speed.
3. Protect yourself during edge finishing by directing the open side
of the guard away from you.
4. Move the tool continuously in a forward and back motion to avoid
creating gouges in the work surface.
5. Remove tool from work surface before turning the tool off. Allow
the tool to stop rotating before setting it down.
WARNING: Do not use edge grinding wheels for surface grinding
applications because edge grinding wheels are not designed for side
pressures encountered with surface grinding. Wheel breakage and
injury may result.
SURFACE FINISHING WITH SANDING FLAP DISCS
1. Allow the tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface, to allow the tool to
operate at high speed.
3. Maintain a 5˚ to 10˚ angle between the tool and work surface.
4. Continuously move the tool in a forward
and back motion to avoid creating gouges
in the work surface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotating before setting it
down.
Mounting and Using Sanding
Backing Pads
Sanding pads and sanding discs must be rated above minimum
accessory speed as shown on tool. Recommended sanding backing
pads and sanding discs are available at extra cost from D
service centers and D WALT dealers.

NOTE : Guard may be removed for sanding applications with backing
pads and sanding discs. Sanding flap discs are considered grinding
wheels by ANSI standards and require the use of a guard. (See
Mounting and Using Depressed Center Grinding Wheels and
Sanding Flap Discs).
MOUNTING SANDING BACKING PADS
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off. An
accidental start-up can cause injury.
CAUTION: Proper guard must be
reinstalled for grinding wheel, sanding flap
disc, wire brush, or wire wheel applications
after sanding applications are complete.
