1. Place or appropriately thread rubber backing pad (L) down to
mount.
2. Place the sanding disc on the rubber backing pad.
3. While depressing spindle lock, thread clamp nut (N) on spindle,
piloting the raised hub on the clamp nut into the center of sanding
disc and backing pad.
4. Tighten the clamp nut with the proper wrench.
5. To remove the wheel, reverse the above procedure.
USING SANDING BACKING PADS
Choose the proper grit sandpaper for your application. Sandpaper
is 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 coarser 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
1. Allow the tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface, allowing tool to operate
at high speed.
3. Maintain a 5˚ to 15˚ angle between the tool and work surface.
The sanding disc should contact approximately one inch of work
surface.
4. Move the tool constantly in a straight line to prevent burning and
swirling of work surface. Allowing the tool to rest on the work
surface without moving, or moving the tool in a circular motion
causes burning and swirling marks on the work surface.
5. Remove the tool from the work surface before turning the tool off.
Allow the tool to stop rotating before setting it down.
Mounting and Using Wire Brushes and
Wire Wheels
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. An
accidental start-up can cause injury.
Wire brushes and wire wheels must be rated above minimum
accessory speed as shown on tool. Use only wire brushes and
wheels provided with a 5/8"–11 or M-14 threaded hub. A type 27
guard is required when using wire brushes and wheels.
CAUTION: Wear work gloves when handling wire brushes or
wheels. Wire brushes and wheels can become sharp.
MOUNTING WIRE BRUSHES AND WIRE WHEELS
1. Thread the wheel on the spindle by hand, seating the wheel
against the mount.
2. Depress the spindle lock button and use a wrench on the hub of
the wire brush or wheel to tighten the wheel.
3. To remove the wheel, depress the spindle lock button and use a
wrench on the hub of the wire brush or wheel to loosen it.
NOTE: Failure to properly seat the wheel hub against the mount
before turning the tool on may result in damage to the tool or wheel.
USING WIRE CUP BRUSHES AND WIRE WHEELS
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces.
1. Allow tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface, to allow the tool to
operate at high speed.
