EDGE GRINDING WITH GRINDING WHEELS
WARNING: Wheels used for cutting and edge grinding may break
or kick back if they bend or twist while the tool is being used to do
cut-off work or deep grinding. Toreduce 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" (13 mm) 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.
