The vibration level value given refers to basic application of the tool. If the
tool is used for other applications or with other tools, or if it is not
maintained properly, the vibration level may differ from the values given.
The above-mentioned causes may lead to higher exposure to vibrations
during the whole work time.
One must implement additional safety measures to protect the operators
from exposure to vibrations, such as maintenance of the electric tool and
work tools, assurance of proper hand temperature, or determination of
the sequence of work operations.
ź
To switch the tool on it is first necessary to depress the unlocking
button (
9
) and then depress the On/Off
(
10
) and hold it
depressed.
ź
To switch the tool off it is enough to release the On/Off
(

).
NOTE:
Due to safety reasons the On/Off
(

) cannot be locked for
continuous operation. It must be kept depressed manually by the operator
during the entire time of the tool operation.

Grinding angle
Do not use the whole disk surface to grind, use its edge only.
For efficient grinding the angle between the disk and machined part

should range from approx. 15 to 30 (see: Fig. , p.

Rough grinding
For best rough grinding efficiency the angle between the disk and

The tool should be slightly pressed against the surface and smoothly
moved along the material. Thanks to the right pressure the machined
part does not heat up excessively, does not lose its color and no grooves
or other roughness will appear on its surface.

Trial start up
After inserting a disk and after connecting the grinder to the mains check
whether the disk is properly fixed and whether it rotates without any
obstacles.
The initial/trial start up should be carried our away from people.
BEFORE YOU START WORKING:
1. Make sure that the power source parameters match the parameters
presented on the grinder nameplate.
2. Make sure that the grinder power switch (
