Using Grinding Wheels
A Type "27" guard must be installed
WARNING
when using a grinding wheel to
provide maximum protection for the operator if
the wheel should break.
When grinding, hold tool at a 5
constant pressure for a uniform finish. Too great an
angle causes concentrated pressure on small areas
which may gouge or burn work surface.
For best result use only this portion of disc
Using Cut-Off Wheels
Type "1" Cut-Off Wheels are suited for small cut-off
and shallow notching operations only.
A Type "1" or Type "41" guard must

be installed when using a cut-off
wheel to provide maximum protection for the
operator if the wheel should break.
Type "1" and Type "41" Cut-Off Wheels are suited for
small cut-off and shallow notching operations only.
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.
Everyone in the area must wear
WARNING
protective clothing and safety
goggles or face shields. Fatigued wires and
residue will fly 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 manufacturer's instructions. Only use acces-
sories with threads matching the tool spindle.
Wire Cup Brush
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).
