Using Cut-Off Wheels
Cut-Off Wheels are suited for small cut-off and shal-
low notching operations only.
WARNING
The guard type and mounting
hardware must match the wheel
type to provide maximum protection for the op-
erator if the wheel should break.
Always install according to the accessory manufac-
turers instructions. Only use accessories matching
the tool spindle. Do not use Type 1 cut-off wheels
with hubs.

When using a cut-off wheel, hold the tool as shown,
using only the edge of the wheel. WARNING! Using
the face of a Cut-Off Wheel (as in grinding) will cause
the Wheel to crack and break, resulting in serious
personal injury.
Using Wire Brushes
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
WARNING
Everyone in the area must wear
protective clothing and safety
goggles or face shields. Fatigued wires and
residue will y off the brush with considerable
force, causing potential for serious injury.
Never exceed Maximum Safe Operating Speed of
brush. Do not use a damaged brush or one that
is functioning improperly (throwing wires, out-
of-balance, etc.). These conditions increase the
possibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
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 manufacturers 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.
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 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 nish.
For best result use only this portion of disc
Hold at a 5° to 15° angle
Cross Sanding - When nishing 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 nish. Failure
to cross sand when changing from a coarse disc to
a nishing 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 ner 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.
Troubleshooting
Deep scratches and circular marks can result from:
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
coarse to nishing 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
MAINTENANCE
WARNING
To reduce the risk of injury, always
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
MILWAUKEE service facility for ALL repairs.
Maintaining Tool
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.
WARNING
To reduce the risk of personal in-
jury and damage, never immerse
your tool, battery pack or charger in liquid or
allow a liquid to ow inside them.
Cleaning
Clean dust and debris from vents. Keep handles
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use ammable or
combustible solvents around tools.
Repairs
For repairs, return the tool, battery pack and charger
to the nearest service center.
