clamp nut (G) on spindle. If the wheel you are
installing is more than 3.17 mm (1/8") 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 3.17 mm (1/8") 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
1. Allow the tool to reach full speed before touching
the tool to the work surface.
2. Apply minimum pressure to the work surface
20 ˚ -30 ˚
FIG. 11
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 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
CAUTION: Wheels used for cutting and edge grinding
FIG. 12
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
12.7 mm [1/2"] in depth). The open side of the guard must
be positioned away from the operator. See the chart on
pages 9–10 for more information.
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. Position yourself so that the open-underside of the
wheel is facing away from you.
4. Once a cut is begun and a notch is established in the workpiece, do not change
the angle of the cut. Changing the angle will cause the wheel to bend and may
cause wheel breakage. Edge grinding wheels are not designed to withstand side
pressures caused by bending.
5. Remove the tool from the work surface before turning the tool off. Allow the tool
to stop rotating before laying it down.
WARNING: Do not use edge grinding/cutting wheels for surface grinding
applications because these 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 the tool to the work surface.
2. Apply minimum pressure to work surface, allowing the tool to operate at high
speed. Sanding rate is greatest when the tool operates at high speed.
3. Maintain a 5 ˚ to 10 ˚ angle between the tool
5 ˚ -10 ˚
FIG. 13
and work surface.
4. Continuously move the tool in a forward and
backward motion to avoid creating gouges in the
work surface.
