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.
CAUTION:
Do not use edge grinding wheels / 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.
Figure K -
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 prevent accidental operation, turn off and unplug tool before
performing the following operations.
Failure to do this could result in serious
personal injury.
NOTE:
Guard may be removed when using sanding backing pads.
WARNING:
Proper guard must be reinstalled for grinding
wheel, sanding flap disc, cutting wheel, wire brush or wire wheel
applications after sanding applications are complete.
1.
Figure L -
Place or appropriately thread backing pad (14)
on the spindle.
2. Place the sanding disc (15) on the backing pad (14).
3. While depressing spindle lock, thread clamp nut (13) 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.
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 removal rates and a rougher finish. Finer
grits yield slower material removal and a smoother finish.
Begin with coarse grit discs for fast, rough material removal. Move to a medium grit
paper and finish with a fine grit disc for optimal finish.
Coarse
16 - 30 grit
Medium
36 - 80 grit
Fine Finishing
100 - 120 grit
Very Fine Finishing
150 - 180 grit
