OPERATION
WARNING:
•
It should never be necessary to force the tool. The
weight of the tool applies adequate pressure.
Forcing and excessive pressure could cause
dangerous wheel breakage.
•
ALWAYS replace wheel if tool is dropped while
grinding.
•
NEVER bang or hit grinding disc or wheel onto
work.
•
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
•
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:
•
After operation, always switch off the tool and wait
until the wheel has come to a complete stop before
putting the tool down.
Grinding and sanding operation
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. 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 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the
workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both A
and B direction.

In case of mounting an abrasive cut-off / diamond wheel
thinner than 4 mm, place the lock nut so that the
protrusion on the lock nut faces outside. Otherwise place
it so that the protrusion on it fits into the inner diameter of
the wheel/disc.
WARNING:
•
When using an abrasive cut-off / diamond 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.
•
A diamond wheel shall be operated perpendicular
to the material being cut.
