1. Do not wear loose clothing when using wire
brushes. The wires may catch on loose clothing
and pull the clothing into the moving parts.
2. Firmly grasp rear handle and side handle before
starting and while using tool. Always test the wire
brush for balance and loose or damaged wires
by running tool at no load speed for at least one
minute before applying it to your work.
3. When applying brush to work, avoid using too
much pressure. This causes over-bending of
wires and heat build-up resulting in premature wire
breakage, rapid dulling and reduced brush life.
Instead of using more pressure, try a wire wheel
brush with more aggressive cutting action
(increased wire size, decreased wire length or
different brush type, i.e. knot type instead of
crimped wire type).
1. Unplug tool and place it upside down on a level
surface. Remove any accessories from spindle.

Position the guard in the location which offers
best control and guard protection. For operating
zones that provide maximum protection for the
operator, see "Grinding".
3. Press in the spindle lock button while tightening
brush with a wrench (not provided with tool).
4. To remove wire wheel brush and guard, unplug
tool and reverse procedure.
Installing Wire Wheel Brushes
Using Wire Brushes
WARNING Because the wires on wire
wheel brushes are directed towards the opera-
tor, a Type 27 guard must be used to protect
the operator when fatigued wires break.

WARNING Never exceed Maximum
Safe Operating Speed of the brush. Do not use
a damaged brush or one which is functioning
improperly (throwing wires, out-of-balance,
etc.). These conditions increase the pos-
sibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
USING WIRE BRUSHES
Selecting Wire Brushes
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc. A wide variety of wire brushes
are available for many applications.
WARNING Everyone in the area must
wear protective clothing and safety goggles
or face shields. Fatigued wires and residue
will fl y off the brush with considerable force,
causing the potential for serious injuries.

contact your local distributor or a service center.
WARNING To reduce the risk of injury,
always unplug the tool before attaching or
removing accessories. Use only specifi cally
recommended accessories. Others may be
hazardous.
WARNING To reduce the risk of injury,
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to fl ow inside the tool.
MAINTENANCE
WARNING To reduce the risk of injury,
always unplug your tool before performing
any maintenance. Never disassemble the tool
or try to do any rewiring on the tool’s electrical
system. Contact a MILWAUKEE service facility
for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general condition of your tool. Inspect guards,
switches, tool cord set and extension cord for
damage. Check for loose screws, misalignment,
binding of moving parts, improper mounting, bro-
ken parts and any other condition that may affect
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. Tag damaged tools “DO NOT USE”
until repaired (see “Repairs”).
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical
operation
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
