processed surface (V). Move the grinder with smooth movements towards you and away from you.
During cutting the cutting disc should be at the straight angle to the surface being cut. Do not cut at any other angle. It is prohibited
to change the angle of the cutting disc to the processed material during cutting. Cutting must be realised along a straight line.
Otherwise the risk of the disc being seized in the material increases, which may cause rebounding of the tool towards the operator,
or the disc may break.
During cutting the grinder must be moved in the same direction as the rotation of the disc (VI).
During work with the grinder do not exert excessive pressure against the material and do not make violent movements, so as to
avoid seizure or breaking of the grinding disk.
Do not overload the grinder – the temperature of the external surfaces must not exceed 60°C.
once the work has fi nished, unplug the grinder and inspect it.
Attention! The disc may rotate for some time once the grinder has been turned off . Before any inspection wait until the disc has
cooled down. During work both the disc and the processed material may heat up to a high temperature.
Rotation control (VII)
The product features the ability to adjust the rotational speed. Adjustment is done by means of a knob. The lower the dial setting,
the lower the speed. Lower speed is recommended to be used when using the product for grinding with wire brushes or grinding
with sandpaper. Reducing the rotational speed results in reduced heating of discs and the material itself, and it also reduces
the amount of dust generated during operation. However, it should be remembered that due to design solutions, the higher the
rotational speed, the better the product cooling. When working at reduced speed, more frequent breaks should be taken to cool
the product.
Remember! While operating the angular grinder:
Always wear protective goggles.
Do not use grinding wheels whose maximum acceptable tangential velocity is lower than 80 m/s!
Do not use grinding wheels whose maximum acceptable rotational speed is lower than the rotational speed of the grinder.
The declared total value of vibrations was measured with a standard method and may be used to compare diff erent tools.
The declared total value of vibrations may be used at the preliminary evaluation of exposition.
Attention! Emission of vibrations during work with the tool may diff er from the declared value, depending on how the tool is used.
Attention! It is required to determine the safety measures to protect the operator, which are based upon evaluation of exposition
under real conditions of operation (including all the stages of the working cycle, e.g. when the tool is off or idling, as well as when
the tool is on).
MAINTENANCE AND OVERHAUL
ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been
fi nished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following
elements: body and handle, conductor with a plug and defl ection, functioning of the electric switch, patency of ventilation slots,
sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee
period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee
rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service
shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be
cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or
cleaning liquids. Tools and handles must be cleansed with a clean cloth.
