the cut. The support must prevent the workpiece parts being separated by the cut from collapsing inward, which may cause the
saw blade to stick in between.
Keep the guide bar in contact with the workpiece throughout the cut.
Do not apply excessive pressure on the workpiece and/or an excessive saw blade speed. Establish the proper pressure and saw
blade speed experimentally by trying to cut scrap material.
Watch the colour of the swarf and the edges of the cut. If discolouration becomes visible, the temperature is too high at the cut due
to excessive pressure on the band saw and/or an excessive saw blade speed. When cutting metals other than steel, excessive
pressure and/or band saw speed may cause caking of the saw blade teeth with the swarf. This will reduce the cutting performance.
Too much pressure and/or speed accelerates the wear of the saw blade. If you notice a decrease in the saw blade teeth sharpness
or broken teeth after a cut, replace the saw blade with a new one. Reduce the pressure and/or the saw blade speed when cutting.
Apply the band saw to the workpiece at an angle to the surface of entry (XI) to facilitate the engagement of the teeth. Apply the
slightest pressure possible and a lower saw blade speed at the start of the cut. With the cut groove properly formed, you can
increase the pressure and/or the saw blade speed as required to cut effi ciently.
Safety instructions for battery charging
Caution! Before starting charging, make sure that the power unit body, cord 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 tool is charging, disconnect the charger from the
mains by removing the power unit 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 plates and checking
their sparking.
Battery storage
Ensure the proper storage conditions to extend the battery's life. The battery can last for approximately 500 charge-discharge
cycles. Store the battery at a temperature ranging from 0ºC to 30ºC at the relative air humidity of 50%. Charge the battery to ap-
prox. 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 tempera-
ture – 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 thor-
oughly 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.
Transport of batteries
Lithium-ion batteries are treated as hazardous materials, 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 en-
trust 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 regula-
tions for the transport of hazardous materials must also be observed.
Charging the battery
Caution! Before charging, disconnect the power unit from the mains by removing the plug from the mains socket. In addition,
remove any dirt and dust from the battery and battery clamps with a soft, dry cloth.
The battery has a built-in charge indicator. The LEDs will light up by pressing the button. The more of them come on, the more
charged the battery is. If the LEDs do not light up when the button is pressed, the battery is discharged.
Disconnect the battery from the tool.
Slide the battery into the charger socket (XII).
Plug the charger into a mains socket.
The red LED will light up, which indicates the charging process.
When charging is complete, the red LED will turn off and the green LED will light up to indicate that the battery is fully charged.
Pull the power unit plug out of the mains socket.
