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 fon^/ard 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 I
diamond wheel
Optional accessory
Awarning : When using an abrasive cut-off
I 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.)
AwARNING: NEVER use cut-off wheel for side
grinding.
AwARNING: 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.
AwARNING: 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.
AwARNING: 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.
Awarning : A diamond wheel shall be oper
ated perpendicular to the material being cut.
