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 appli-
cation. 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 oper-
ate 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 sur-
face 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
Turn off and unplug tool before making any adjustments or
removing or installing accessories. Before reconnecting the
tool, depress and release the trigger switch to ensure that the
tool is off.
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 soft 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 soft
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.
