Using Cut-Off Wheels (Fig. 12)
Type “1” Cut-Off Wheels are suited for small cut-off and shallow notch-
ing operations only.
1. Firmly grasp body of tool and side handle before starting and while
using tool. Allow wheel to come to full speed before starting.
2. When using a cut-off wheel, hold Sander/Grinder as shown, using
only the edge of the wheel.
A Type “1” guard must be installed when using
a cut-off wheel to provide maximum protection
for the operator if the wheel should break.
WARNING!
Fig. 12
3. Control pressure and surface contact between disc and workpiece.
Too much pressure slows cutting speed.
Using the face of a Cut-Off Wheel (as in grinding)
will cause the Wheel to crack and break, resulting
in serious personal injury.
WARNING!
Everyone in the area must wear 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.
WARNING!
Installing Wire Cup Brushes (Fig. 13)
2. To install, thread wire cup brush onto spindle. Press the spindle lock
button while tightening brush with a 7/8" open end wrench (not
provided with tool).
3. To remove wire cup brush, unplug tool and reverse procedure.
Using Wire Wheel Brushes (Fig. 14)
WARNING!
Because the wires on wire wheel brushes are
directed towards the operator, a guard must be
used to protect the operator when fatigued wires
break.
WARNING!
Never exceed Maximum Safe Operating Speed of
brush. Do not use a damaged brush or one which
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.
1. Unplug tool and place it upside down on a level surface as shown.
Remove any accessories from spindle.

Guard
Wire wheel brushes are useful for removing rust, scale, burrs, weld
slag, etc. A wide variety of wire brushes are available for many
applications.
Test wire wheel 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. During this time, no one should stand in front of or in line with
it. 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).
