Operation with wire cup brush
Optional accessory
CAUTION: Never switch on the tool when it
is in contact with the workpiece, it may cause an
injury to operator.
CAUTION: Always wear safety goggles or a
face shield during operation.
CAUTION: Check operation of brush by run-
ning tool with no load, insuring that no one is in
front of or in line with brush.
CAUTION: After operation, always switch off
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION: ALWAYS hold the tool firmly with one
hand on housing and the other on the side grip (handle).
NOTICE: Avoid applying too much pressure
which causes over bending of wires when using
the wire cup brush. It may lead 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.
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° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both
forward and backward direction.
Operation with abrasive cut-off /
diamond wheel
NOTICE: Avoid applying too much pressure
which causes over bending of wires when
using wire wheel brush. It may lead to premature
breakage.
Optional accessory
Usage example: operation with wire wheel brush

WARNING: Do not "jam" the wheel or apply
excessive pressure. Do not attempt to make an exces-
sive 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.
MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
WARNING: 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.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
WARNING: 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.
WARNING: A diamond wheel shall be oper-
ated perpendicular to the material being cut.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
