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.

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.
BEFORE YOU START WORKING:
The initial/trial start up should be carried our away from people.
1. Make sure that the power source parameters match the parameters
presented on the grinder nameplate.
2. Make sure that the grinder power switch (
8
) is in off position.
3. When using an extension cable make sure the extension cable
parameters and conductor sections match the grinder parameters. It
is recommended to use the shortest extension cables possible. The
extension cable should be fully unwound.

NOTE:
Before you install or remove the grinding disk, make sure that the
device switch is in off position and that it is disconnected from the mains.
Before installation clean the grinder spindle and all fixing components.
Make sure the admissible size and speed of the grinding disk matches
the parameters presented on the grinder nameplate. The grinding disk
should be installed without any clearance on the fixing flange. Do not
use any reduction washers or adapters.
To install a disk:
1.
Place the grinder with the spindle (
11
) up. Insert the fixing flange (
4
)
with its bottom projecting part with a groove onto the spindle shaft
to mesh the flange on the spindle.
2. Insert a disk (
12
) with its convex part down onto the upper
projecting part of the fixing flange.
3. Screw the compression nut (
3
) onto the spindle to secure the disk
properly. (The compression nut has a concave and convex side.
Depending on the rated disk thickness it can be applied on one or the
other side. (see: Fig.
G
p.2).
4. Press the spindle lock button (
6
) and tighten the nut using the pin
towards the arrow, press the switch (
8
), then press the locking lever
farther towards the arrow.
To stop the tool working locked for continuous operation:
1-press the switch to the end,
2- release it (see: Fig.
E
, p.1).
NOTE:
Never put the grinder aside when the switch is locked. When the tool
is not used disconnect the power cord plug from the mains.

Tips regarding the operation
ź
The objects to be machined that do not rest securely under their own
weight should be fixed properly.
ź
Avoid excessive pressure exerted on the disk. Grinding should be
carried out using the weight of the tool. Only slight pressure is allowed
when cutting. Excessive pressure reduces the disk speed, which results
in producing rough surfaces. In addition, it results in overheating and
damage to the motor.
n
Grinding direction
When using a new grinding disk move the grinder back (B direction)
(see: Fig.
I
, p.2), then the new disk edge will be rounded, which will allow
the user to move the tool in any direction.
n
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
º
º
should range from approx. 15 to 30 (see: Fig.
