Using Cut-Off Wheels
Cut-Off Wheels are suited for small cut-off and
shallow notching operations only.
The guard type must match the
WARNING
wheel type to provide maximum
protection for the operator if the wheel should break.
When using a cut-off wheel, hold the tool as shown,
using only the edge of the wheel.
Using the face of a Cut-Off Wheel (as
WARNING
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.
Do not remove the Type 27 Guard when using a
wire cup brush. Do not use with the Type 1
clipon guard installed. Rotate the guard as
shown below. Do not let the guard interfere with
the wire cup brush. If the wire cup brush is worn
and touching the guard, replace the accessory
immediately.
If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work
load and centrifugal forces.
Always install wire brushes according to the
accessory manufacturer's instructions. Only use
accessories with threads matching the tool spindle.
While using a wire cup brush, adjust the guard for
viewing the workpiece.
Wire Wheel Brush
Type 27 Guard
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
(increased wire size, decreased wire length or
different brush type (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
forward to produce the desired finish.
For best result use only this portion of disc
Cross Sanding - When finishing 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 finish.
Failure to cross sand when changing from a coarse
disc to a finishing disc may result in deep scratches
and circular marks.
Removing Welds or Hammer Marks - When
removing welds or hammer marks, limit coarse
sanding to the immediate area. Use successively
finer grits to smooth surface.
Finishing Metal - Constantly move across the
surface. 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.
To reduce risk of injury, always
WARNING
remove the battery pack and
keep tool in storage position while transporting
and storing. Carry tool with fingers off the
trigger.
