EDGE GRINDING WITH GRINDING WHEELS
CAUTION: 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. 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 pages 10 and 11 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 work-
piece, 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 pres-
sures 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 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.
MOUNTING SANDING BACKING PADS
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
NOTE: Guard may be removed when using sanding backing pads
CAUTION: Proper guard must be reinstalled for grinding wheel,
sanding flap disc, wire brush or wire wheel applications after sand-
ing applications are complete.
1. Place or appropriately thread backing
pad (N) on the spindle.
2. Place the sanding disc (O) on the
backing pad (N).
3. While depressing spindle lock, thread
clamp nut (P) on spindle, piloting the
raised hub on the clamp nut into the
center of sanding disc and backing
pad.
4. Tighten the clamp nut by hand. Then
depress the spindle lock button while
turning the sanding disc until the
sanding disc and clamp nut are snug.
5. To remove the wheel, grasp and turn the backing pad and
sanding pad while depressing the spindle lock button.
