A Type "27" guard must be installed when using
a wire wheel brush to provide maximum protec-
tion for the operator when fatigued wires break.
(See "Removing/Installing/Adjusting the guard".)
Always install wire brushes according to the acces-
sory manufacturer's instructions. Only use acces-
sories with threads matching the tool spindle.
Guard
Test wheel for balance and loose or damaged wires
by letting it spin for one minute before applying it to
the workpiece. During this time, no one should stand
in front of or in line with it.
Control pressure and surface contact between
wheel and workpiece. Too much pressure causes
over-bending of wires and heat build-up causing
premature wire breaking, rapid dulling and reduced
brush life. Instead of more pressure, try a wire wheel
with more aggressive cutting action (increased wire
size, decreased wire length or different brush type
(knot type vs. crimped wire type).
Using Sanding Discs
Hold tool at 5° to 15° angle to ensure proper sanding
pressure and control. Too great an angle will result
in too much pressure and could cause excessive
wear to the disc and workpiece. Too small an angle
will reduce control.
Use long, sweeping, side to side strokes, advancing
forward to produce the desired finish.
For best result use only this portion of disc
Cross Sanding - When finishing a surface that

has been prepared by a coarse disc or wheel, sand
at right angles to the strokes made by the coarser
disc. Finishing marks left from previous sanding are
easily seen and removed for a uniform finish. Failure
to cross sand when changing from a coarse disc to
a finishing disc may result in deep scratches and
circular marks.
Removing Welds or Hammer Marks - When remov-
ing welds or hammer marks, limit coarse sanding to
the immediate area. Use successively finer grits to
smooth surface.
Finishing Metal - Constantly move across the sur-

face. Work faster on curved surfaces where contact

areas are smaller and pressure is greater. Flat areas

may appear at the end of the stroke when pressure
is too heavy. Ease up on pressure at end of each
stroke and when reversing strokes.
Deep scratches and circular marks can result from:
Wire
• Using too coarse a grit
Cup
• Using a partially glazed disc
Brush
• Dirt or loose metal on the workpiece
• Failure to sand across the grain when changing from
coarse to finishing discs
• Failure to use closed coated discs to reduce the
problem of grains working loose and scratching the
workpiece
Bluish discoloration of metal surface indicates:
• Excessive heat caused by circular motion in a small area
• Excessive pressure
• Use of worn out or glazed discs
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the tool, battery pack or charger. Contact a
MILWAUKEE service facility for ALL repairs.
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool, battery pack and charger to a MILWAUKEE
service facility for inspection.
If the tool does not start or operate at full power with
a fully charged battery pack, clean the contacts on
the battery pack. If the tool still does not work prop-
erly, return the tool, charger and battery pack, to a
MILWAUKEE service facility for repairs.
Hold at a
5° to 15°
angle
your tool, battery pack or charger in liquid or
allow a liquid to flow inside them.
