low notching operations only.
WARNING
The guard type must match the
wheel type to provide maximum
protection for the operator if the wheel should
break.
Always install according to the accessory manufac-
turer’s instructions. Only use accessories matching
the tool spindle.

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
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 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.
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 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
For best result use only this portion of disc
Hold at a 5° to 15° angle
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.
