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.
Mount urethane washer then thread wire cup brush onto
spindle and tighten with supplied wrench. When using
brush, avoid applying too much pressure which causes
over bending of wires, leading to premature breakage.
NOTE:
When using wire cup brush, mount urethane
•
washer to the spindle. It will make it easier to
remove wire cup brush.
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
can shatter during use and guard helps to reduce
chances of personal injury.

premature breakage.
Operation with abrasive cut-off /
diamond wheel (optional accessory)
WARNING:
When using an abrasive cut-off / diamond wheel,
•
be sure to use only the special wheel guard
designed for use with cut-off wheels. (In some
European countries, when using a diamond wheel,
the ordinary guard can be used. Follow the
regulations in your country.)
NEVER use cut-off wheel for side grinding.
•
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.
During cutting operations, never change the angle
•
of the wheel. Placing side pressure on the cut-off
wheel (as in grinding) will cause the wheel to crack
and break, causing serious personal injury.
A diamond wheel shall be operated perpendicular
•
to the material being cut.
Mount the inner flange onto the spindle. Fit the
wheel/disc on the inner flange and screw the lock nut
onto the spindle.
