15° angle while sanding so that only about 1" of
the surface around the edge of the disc contacts
the work.
WARNING!
If the disc (accessory) is held
flat or the back edge of the disc comes in contact
with the work, a violent thrust to the side may
result.
If sander is tilted too much, sanding action will
be too great and a rough cut surface or gouging
and snagging will result.
Guide the Disc Sander with crosswise strokes.
Be careful not to hold the sander in one spot too
long. Do not use a circular motion, as this
makes swirl marks. Test before use on scrap
stock.
Do not force or apply pressure when sanding.
Use only the weight of the tool for pressure.
Excess pressure actually slows the tool down,
and over loads the motor. If faster stock removal
is desired, change to a coarser grit disc.
Remove gummy paint from metal with an "open
coat" disc. Sand until sparks start to appear,
then stop and change to a "closed coat" disc to
remove any remaining paint.
Sanding Wood
When sanding wood the direction of the disc
motion at the contact point should parallel the
grain as much as possible. The rapid cut of
discs and the swirl type scratch pattern they
occasionally create generally prohibit their use
for producing the final finish.
Scratches and circular marks are usually the
result of using too coarse a grit. When changing
to a finer grit, move across the sanding lines that
were made by a previous coarser disc.
Sanding Metal
When sanding automobiles or appliances, wipe
the metal clean with a non-flammable solvent
or a commercial cleaner to remove all wax and
grease. By doing this first, the sanding discs
will sand better and last longer.
For heavy duty work, use a coarse grit disc first.
Follow-up with a medium grit to remove

scratches. To produce smooth finish, use fine
grit disc.
MASONRY CUTTING
For cutting masonry materials like brick, tile,
stone, etc. it is best to use a dry diamond cutting
wheel. The lock nut and backing flange supplied
with this grinder are not intended for use with
dry diamond cutting wheels. Use only lock nut
and flange with equal diameters. The wheel
guard MUST be used with a dry diamond
cutting wheel.
WARNING!
fluid with this tool for cutting.
Disconnect tool from power source before
attaching cutting wheel. With wheel guard in
place, assemble flange, cutting wheel and lock
nut in order shown on page 2.
When cutting make only small passes through
workpiece at a time. Be aware that "Kickback"
can occur at any time. Keep both hands on tools
for maximum control.
WIRE BRUSH OPERATIONS
Wire brushes are intended to "clean" structural
steel, castings, sheet metal, stone and concrete.
They are used to remove rust, scale and paint.
Before assembling wire brush to this tool
disconnect from the power source. Wire brushes
are equipped with their own threaded hub.
Simply thread on to spindle be sure to seat
against shoulder before turning tool "ON".
WARNING!
not specified in this manual may create a hazard.
