In the case of wheels enabling the installation of the sandpaper disc with Velcro, only sandpaper discs with the diameter specifi ed
in the technical data table should be used. The disc should be placed concentrically on the wheel. The edge of the disc must not
project beyond the edge of the wheel.
It is also possible to use diamond grinding wheels with the dimensions specifi ed in the technical data table intended for dry cutting
and grinding. Perform the assembly in the same manner as in the case of grinding wheels. When using diamond segmented discs,
the gap between the segments must not exceed 10 mm, measured at the perimeter of the disc, and the segments must have a
negative angle of attack.
It is recommended to use grinding wheels made of materials intended for machining a given type of metal. Refer to the
documentation provided with the grinding wheel.
Grinding wheels intended for machining stone or diamond grinding wheels for dry working can be used for the machining of
ceramic materials.
It is recommended to use wire brushes and sandpaper discs to remove old paint coats from metal parts.
It is forbidden to modify the fi xing hole, spindle or use reduction rings to adjust the diameter of the fi xing hole to the spindle
diameter. It is forbidden to use grinding wheels with a fi xing hole diameter other than specifi ed in the technical data table. It is
forbidden to use grinding wheels with a cutting chain or cutting discs because they increase the risk of tool kickback towards the
operator.
Caution! It is forbidden to use discs other than those allowed for use in this manual, even if they can be assembled on the grinder
spindle. Improper discs may not withstand the loads generated during the operation of the angle grinder. Damaged or decaying
grinding wheels present a risk of serious injury or death.
CAUTION! All operations mentioned in this chapter must be carried out with the power supply disconnected – the battery must
be disconnected from the tool!
Safety instructions for battery charging
Caution! Before starting charging, make sure that the power unit body, cable and plug are not cracked or damaged. It is forbidden
to use a defective or damaged charging station and power unit! Use only the supplied charging station and power unit to charge
the batteries. The use of another power unit may result in fi re or damage to the tool. The battery should only be charged in a
closed, dry room, protected against unauthorised access, especially by children. Do not use the charging station and power unit
without the constant supervision of an adult! If you need to leave the room where the product is being charged, disconnect the
charger from the mains by removing the power unit's plug from the mains socket. If smoke, suspicious odours, etc. are escaping
from the charger, remove the charger plug from the mains socket immediately!
The tool is supplied with an uncharged battery and should therefore be charged according to the procedure described below with
the included power unit and charging station before use. Li-ion (lithium-ion) batteries do not have the so-called "memory eff ect",
which means they can be recharged at any time. However, it is recommended to discharge the battery during normal operation
and then charge it to full capacity. If, due to the nature of work, it is not possible to use the battery in such a manner every time,
it should be done at least every several work cycles. Never discharge any batteries by short-circuiting the battery plates, as this
will cause irreparable damage! In addition, do not check the battery charge status by short-circuiting the electrodes and checking
their sparking.
Storing the battery
Ensure the proper storage conditions to extend the battery's life. The battery can withstand approximately 500 charge-discharge
cycles. Store the battery at a temperature ranging from 0ºC to 30ºC at a relative air humidity of 50%. Charge the battery to approx.
70% of its total capacity to store it for a longer period of time. In case of prolonged storage, the battery should be periodically
charged once a year. Do not over-discharge the battery as this will shorten its life and may cause irreparable damage. During
storage, the battery will gradually discharge due to leakage. The self-discharge process depends on the storage temperature –
the higher the temperature is, the faster the discharge process is. If the batteries are stored incorrectly, the electrolyte may leak.
In case of leakage, secure the leak with a neutralising agent. In the case of electrolyte contact with eyes, rinse eyes thoroughly
with water, and immediately seek medical attention. It is not allowed to use the tool with a damaged battery. If the battery is
completely worn, return it to a specialist waste disposal centre.
Transporting the batteries
Lithium-ion batteries are treated as hazardous goods according to legal regulations. The user of the tool can transport the product
together with the battery and the batteries alone by land. In that case, no additional conditions have to be met. If you entrust
transport to third parties (e.g. a courier company), follow the regulations regarding the transport of hazardous goods. Before
shipping, please contact a properly qualifi ed person.
It is not allowed to transport damaged batteries. For the duration of transport, remove the demountable batteries from the product
and secure the exposed contacts, e.g. by covering them with insulation tape. Protect the batteries in the packaging in such a way
that they do not move inside the packaging during transport. National regulations for the transport of hazardous materials must
also be observed.
Rechargeable battery
Only one of the following YATO Li-Ion 18 V batteries can be used to power the tool: YT-82842, YT-82843, YT-82844, YT-82845,
