Operation with wire cup brush (optional
accessory)
007242
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.
Remove the battery cartridge from the 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 supplied wrench. When using
brush, avoid applying too much pressure which causes
over bending of wires, leading to premature breakage.

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.

Operation with abrasive cut-off wheel
007244
WARNING:
When using an abrasive cut-off wheel, be sure to
•
use only the special wheel guard designed for use
with cut-off wheels.
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.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
