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).
Grinding and sanding operation
►
Fig.7
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:
When using an abrasive cut-off /
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.)
WARNING:
NEVER use cut-off wheel for side
grinding.
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.

MAINTENANCE
CAUTION:
Always be sure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
NOTICE:

Limit mark
Check the carbon brushes regularly.
Replace them when they wear down to the limit mark.
Keep the carbon brushes clean and free to slip in the
holders. Both carbon brushes should be replaced at the
same time. Use only identical carbon brushes.
1.
Use a screwdriver to remove the brush holder
caps.
2.
Take out the worn carbon brushes, insert the new
ones and secure the brush holder caps.
