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 11 and 12 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 serious personal
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
WARNING: To reduce the risk of serious personal injury,
turn tool off and and remove battery pack before making any
adjustments or removing/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 sanding
applications are complete.
1. Place or appropriately thread backing pad (Q) on the spindle.
2. Place the sanding disc (R) on the backing pad (Q).
3. While depressing spindle lock, thread
clamp nut (S) on spindle, piloting the
raised hub on the clamp nut into the
center of san ding 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.
