OPERATION
WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure.
Forcing and excessive pressure could cause
dangerous wheel breakage.
• ALWAYS replace wheel if tool is dropped while
grinding.
• NEVER bang or hit grinding disc or wheel onto
work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
• After operation, always switch off the tool and wait
until the wheel has come to a complete stop before
putting the tool down.
Grinding and sanding operation
A B
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an angle
of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the work-
piece. Once the edge of the wheel has been rounded off
by use, the wheel may be worked in both A and B direc-
tion.
Operation with diamond wheel
(optional accessory )
CAUTION:
• Do not "jam" the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of
kickback, wheel breakage and overheating of the
motor may occur.
• Do not start the cutting operation in the workpiece.
Let the wheel reach full speed and carefully enter

into the cut moving the tool forward over the
workpiece surface. The wheel may bind, walk up or
kickback if the power tool is started in the
workpiece.
• A diamond wheel shall be operated perpendicular
to the material being cut.
Operation with wire cup brush
(optional accessory)
CAUTION:
• Check operation of brush by running tool with no
load, insuring that no one is in front of or in line with
brush.
• Do not use brush that is damaged, or which is out
of balance. Use of damaged brush could increase
potential for injury from contact with broken brush
wires.
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Thread wire cup brush onto spindle and tighten with sup-
plied wrench. When using brush, avoid applying too
much pressure which causes over bending of wires,
leading to premature breakage.
Operation with wire wheel brush
(optional accessory)

CAUTION:
• Check operation of wire wheel brush by running
tool with no load, insuring that no one is in front of
or in line with the wire wheel brush.
• Do not use wire wheel brush that is damaged, or
which is out of balance. Use of damaged wire
wheel brush could increase potential for injury from
contact with broken wires.
• ALWAYS use guard with wire wheel brushes,
assuring diameter of wheel fits inside guard. Wheel
