Installing wire wheel brush
Optional accessory
CAUTION:
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.
CAUTION:
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.
Place the tool upside down to allow easy access to the
spindle.
Remove any accessories on spindle. Thread wire wheel
brush onto spindle and tighten with the wrenches.

NOTE:
For information how to install the dust col-
lecting wheel guard, refer to the manual of the dust
collecting wheel guard.
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 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).
NOTE:
A dual purpose wheel can be used for both
grinding and cutting-off operations.
Refer to the "Grinding and sanding operation" for
grinding operation, and refer to the "Operation with
abrasive cut-off / diamond wheel" for cutting-off
operation.
Grinding and sanding operation

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
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-off 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.
