to shallow cutting and notching (less than 1/2" [13 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 pages 14 and 15 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.
WARNING: Proper guard must be reinstalled for grinding
wheel, cutting wheel, sanding flap disc, wire brush or wire wheel
applications after sanding applications are complete.
1. Place or appropriately thread backing pad (P) on the spindle.
2. Place the sanding disc (Q) on the backing pad (P).
3. While depressing spindle lock button,
thread clamp nut (R) 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.
5. To remove the wheel, grasp and turn
the backing pad and sanding pad
while depressing the spindle lock
button.
USING SANDING BACKING PADS
Choose the proper grit sanding discs for your application. Sanding
discs are available in various grits. Coarse grits yield faster material
5˚–10˚
removal rates and a rougher finish. Finer grits yield slower material
removal and a smoother finish.
