recess is seated onto the flats of the
spindle by pushing and twisting the flange
before placing wheel.
2. Place wheel against the backing flange,
centering the wheel on the raised section
(pilot) of the backing flange.
3. While depressing the spindle lock button,
thread the clamp nut (F) on spindle. If
the wheel you are installing is more than
1/8" (3.31 mm) thick, place the threaded
clamp nut on the spindle so that the
raised section (pilot) fits into the center of
the wheel. If the wheel you are installing
is 1/8" (3.31 mm) thick or less, place
the threaded clamp nut on the spindle
so that the raised section (pilot) is not
against the wheel.
4. While depressing the spindle lock button,
tighten the clamp nut with a wrench.
5. To remove the wheel, depress the spindle
lock button and loosen the threaded
clamp nut with a wrench.
NOTE: If the wheel spins after the clamp
nut is tightened, check the orientation of the
threaded clamp nut. If a thin wheel is installed
with the pilot on the clamp nut against the
wheel, it will spin because the height of the
pilot prevents the clamp nut from holding
the wheel.
SURFACE GRINDING WITH GRINDING WHEELS (FIG. 9)
1. Allow the tool to reach full speed before touching the tool to the
work surface.
2. Apply minimum pressure to the work surface, allowing the tool
to operate at high speed. Grinding rate is greatest when the tool
operates at high speed.
3. Maintain a 20˚ to 30˚ angle between the
20˚–30˚
FIG. 9
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 laying it down.
EDGE GRINDING WITH GRINDING WHEELS (FIG. 10)
CAUTION: Wheels used for cutting and
FIG. 10
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 cut-off wheel, use a closed,
Type 1 guard. See the chart on page 10 for
more information. 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.
