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, 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 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"
(12.7 mm) 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 8 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.
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.
20˚-30˚ 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 and work surface.
4. Continuously move the tool in a
forward and backward 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.
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.
