15 ENGLISH
OPERATION
WARNING: It should never be necessary to
force the tool. The weight of the tool applies ade-
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING: ALWAYS replace wheel if tool is
dropped while grinding.
WARNING: NEVER hit the workpiece with the
wheel.
WARNING: Avoid bouncing and snagging
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
WARNING: NEVER use tool with wood cutting
blades and other saw blades. Such blades when
used on a grinder frequently kick and cause loss of
control leading to personal injury.
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: After operation, always switch o
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION: ALWAYS hold the tool rmly with
one hand on housing and the other on the side
grip (handle).
NOTE: A dual purpose wheel can be used for both
grinding and cutting-o operations.
Refer to the "Grinding and sanding operation" for
grinding operation, and refer to the "Operation with
abrasive cut-o / diamond wheel" for cutting-o
operation.
Grinding and sanding operation
► Fig.24
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 o by use, the wheel may be worked in both
forward and backward direction.
Usage example: operation with cup-type diamond
wheel
► Fig.25
Keep the tool horizontally and apply the entire cup-type
diamond wheel to the workpiece surface.
Operation with abrasive cut-o /
diamond wheel
Optional accessory
WARNING: 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.
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.
WARNING: During cutting operations, never
change the angle of the wheel. Placing side pres-
sure on the cut-o wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING: A diamond wheel shall be oper-
ated perpendicular to the material being cut.

Operation with wire cup brush
Optional accessory
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.
NOTICE: Avoid applying too much pressure
which causes over bending of wires when using
the wire cup brush. It may lead to premature
breakage.
Usage example: operation with 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.
NOTICE: Avoid applying too much pressure
which causes over bending of wires when
using wire wheel brush. It may lead to premature
breakage.
