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.

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.
G
, p.
3
).
n
Rough grinding
For best rough grinding efficiency the angle between the disk and
º
º
machined surface should range from approx. 30 do 40 (see: Fig.
H
, p.
3
).
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.
NOTE:
Never use cutting disks to grind/remove layers.
n
Cutting
While cutting with the tool do not exert excessive pressure, do not tilt
and do not oscillate. Move the tool at a constant speed adjusted to the
material machined.
Do not brake the rotating disk by pressing it against other objects.
NOTE:
Observe proper cutting direction. Cutting should be carried out at
the direction shown on the disk (see: Fig.
I
, p.
3
). Do not cut in opposite
tightens up during operation. Observing this recommendation
will help avoiding damage to the motoreducer casing during the
disk removal.
NOTE:
The spindle lock button (
6
) can be pressed only when the spindle is
stopped!
Never use a disk with improper maximum admissible speed!
n
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 (
7
) 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
REGULAR OPERATION:
extension cable should be fully unwound.

Mounting the side handle
To turn on the angle grinder push the switch (

NOTE:
For safety reasons always use the side handle (
1
).
To turn the tool off press the rear part of the on/off switch (a spring
automatically moves the switch back to off position).
Depending on working requirements the handle can be inserted in one of
the three openings provided in grinder's head (see: Fig.
B
, p.
2
).
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.

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 (

) up. Insert the fixing flange
(

) with its bottom projecting part with a groove onto the spindle
shaft to mesh the flange on the spindle.
2. Insert a disk (
