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 (FIG. 2). Type 1 guards are avail-
able 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 grind-
ing 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

ing pads and sanding discs. Sanding flap discs are considered
grinding wheels by ANSI standards and require the use of a guard.

sanding flap disc, wire brush, or wire wheel applications after sand-
ing applications are complete.
