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
(knot type vs. crimped wire type).
Using Sanding Discs
Hold tool at to
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
For best result use only this portion of disc
Hold at a
5° to 15° angle
MAINTENANCE
WARNING
To reduce the risk of injury, always
Cross Sanding -
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
to cross sand when changing from a coarse disc to
circular marks.

WARNING
Chemical Burn Hazard.
This device contains a
jury and damage, never immerse
your tool, battery pack or charger in liquid or
ONE-KEY™
lithium button/coin cell battery. A new
or used battery can cause severe in-
ternal burns and lead to death in as
unplug the charger and remove the
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the tool, battery pack or charger. Contact a

Maintaining Tool
little as 2 hours if swallowed or enters the body.
Always secure the battery cover. If it does not
close securely, stop using the device, remove the
batteries, and keep it away from children. If you
think batteries may have been swallowed or en-
tered the body, seek immediate medical attention.
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
properly, return the tool, charger and battery pack,
to a
MILWAUKEE
®
service facility for repairs.

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.
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.
Using too coarse a grit
Using a partially glazed disc
Dirt or loose metal on the workpiece
Failure to sand across the grain when changing from
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
Removing Welds or Hammer Marks -
When remov-
ing welds or hammer marks, limit coarse sanding 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.
Troubleshooting
Deep scratches and circular marks can result from:
Wire Wheel Brush
Guard
Wire Cup Brush
