turn the backing pad and sanding
pad while depressing the spindle
lock button.
USING SANDING BACKING PADS
(FIG. 14)
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.

1. Allow the tool to reach full speed before touching 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 15° angle between the tool and work surface.
The san ding disc should contact approximately 1" (25.4 mm) 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 work surface before turning tool off. Allow
the tool to stop rotating before laying it down.
MOUNTING AND REMOVING HUBBED WHEELS (FIG. 15)
Hubbed wheels install directly on the
5/8"-11 threaded spindle. Thread of
accessory must match thread of spindle.
1. Remove backing flange by pulling
away from tool.
2. Thread the wheel on the spindle (E)
by hand.
3. Depress the spindle lock button and
use a wrench to tighten the hub of the
wheel.
4. Reverse the above procedure to
remove the wheel.
NOTICE: Failure to properly seat the wheel before turning the tool on
may result in damage to the tool or the wheel.
Precautions To Take When Sanding Paint
1. Sanding of lead based paint is NOT RECOMMENDED due to
the difficulty of controlling the contaminated dust. The greatest
danger of lead poisoning is to children and pregnant women.
2. Since it is difficult to identify whether or not a paint contains
lead without a chemical analysis, we recommend the following
precautions when sanding any paint:
PERSONAL SAFETY
1. No children or pregnant women should enter the work area
where the paint sanding is being done until all clean up is
completed.
2. A dust mask or respirator should be worn by all persons entering
the work area. The filter should be replaced daily or whenever the
wearer has difficulty breathing.
