Sigurnosne informacije
Uvijek se pridržavajte osnovnih sigurnosnih mjera opreza kako biste smanjili rizik od požara, strujnog udara i tjelesnih ozljeda prilikom korištenja električnih alata. Sačuvajte ovaj priručnik za buduću upotrebu.
- Sigurnost radnog područja: Radno područje održavajte čistim i dobro osvijetljenim. Ne koristite električne alate u eksplozivnim atmosferama, kao što je prisustvo zapaljivih tekućina, plinova ili prašine.
- električna sigurnost: Izbjegavajte kontakt tijela sa uzemljenim površinama. Ne izlažite električne alate kiši ili vlazi.
- Lična sigurnost: Uvijek nosite zaštitu za oči, zaštitu za sluh i odgovarajuće radne rukavice. Obucite se prikladno; izbjegavajte široku odjeću ili nakit.
- Upotreba i njega alata: Ne forsirajte električni alat. Koristite odgovarajući električni alat za vašu primjenu. Isključite bateriju iz električnog alata prije bilo kakvih podešavanja, promjene pribora ili skladištenja električnog alata.
- Upotreba i održavanje akumulatorskog alata: Punite samo punjačem koji je odredio proizvođač. Koristite električne alate samo sa posebno namijenjenim baterijama.

2. Auxiliary Handle Attachment
The auxiliary handle provides additional control and stability during operation.
- Otpustite pomoćnu ručku okretanjem u smjeru suprotnom od kazaljke na satu.
- Gurnite ručku na prednju stranu tijela alata.
- Rotate the handle to the desired position for comfortable and secure grip.
- Zategnite ručku okretanjem u smjeru kazaljke na satu dok se čvrsto ne pričvrsti.

3. SDS-Plus Bit/Chisel Installation
This tool uses SDS-Plus bits for quick and secure accessory changes.
- Očistite dršku svrdla ili dlijeta.
- Pull back the chuck collar (1) and insert the SDS-Plus bit into the chuck.
- Release the chuck collar. The bit should click into place. Pull on the bit to ensure it is securely locked. A slight axial play is normal for SDS-Plus systems.
- Da biste uklonili, povucite prirubnicu stezne glave i izvucite svrdlo.

4. Depth Stop Adjustment
The depth stop allows for precise control over drilling depth.
- Umetnite šipku graničnika dubine u otvor na dodatnoj dršci.
- Adjust the rod to the desired drilling depth by sliding it in or out.
- Secure the depth stop by tightening the knob on the auxiliary handle.

Radni režimi
The SFMCH900B features a mode selector switch (2) to choose between different operating functions:

Figure 8: The mode selector switch allows selection of drilling, hammer drilling, or chiseling functions.
1. Hammer Drilling Mode (Hammer and Drill Bit Icon)
This mode is for drilling in concrete, masonry, and brick. It combines rotary action with powerful hammer blows for fast drilling progress.

Figure 9: Demonstrating hammer drilling into a wall.
2. Drilling Mode (Ikona svrdla)
This mode provides rotary action only, suitable for drilling in wood, metal, plastics, and ceramics. The impact mechanism is disengaged.
3. Chiseling Mode (Chisel Icon)
This mode provides hammer action only with a rotary stop, ideal for light chiseling work in plaster, tiles, or for removing small amounts of material. Ensure a chisel bit is installed.

To change modes, rotate the mode selector switch to the desired icon. Ensure the tool is off before changing modes.
Operacija
Before starting any operation, ensure the work area is clear and you are wearing appropriate personal protective equipment.
- Pokretanje alata: Squeeze the trigger switch (5) to start the tool. The speed is variable depending on the pressure applied to the trigger.
- Zaustavljanje alata: Otpustite okidač da biste zaustavili alat.
- Primjena pritiska: Apply steady, firm pressure to the tool. Do not lean into the tool excessively; let the hammer mechanism do the work.
- pregrijavanje: If the tool becomes excessively hot, run it without load for a few minutes to cool the motor.
Održavanje
Redovno održavanje osigurava dugotrajnost i optimalne performanse vašeg alata.
- čišćenje: Keep the ventilation slots clean and free from dust. Use a soft brush or dry cloth to clean the tool. Do not use water or chemical cleaners.
- Motor bez četkica: The brushless motor design significantly reduces maintenance requirements compared to traditional brushed motors, as there are no carbon brushes to replace.
- Skladištenje: Alat i bateriju čuvajte na hladnom i suhom mjestu, dalje od direktne sunčeve svjetlosti i vlage. Prije skladištenja provjerite je li baterija izvađena iz alata.
- Održavanje pribora: Keep drill bits and chisels clean and sharp for best performance.
