2. Sigurnosne informacije
Always prioritize safety when operating power tools and accessories. Failure to follow safety guidelines can result in serious injury.
- Nosite ličnu zaštitnu opremu (LZO): Always wear safety glasses, hearing protection, and a dust mask when drilling. Gloves are recommended for grip and protection.
- Kompatibilnost alata: Ensure the drill bit is compatible with your rotary hammer drill. The DW5540 features an SDS+ shank and is designed for SDS+ chucks only.
- Osigurajte radni komad: Always secure the material you are drilling into to prevent movement during operation.
- Pregledajte prije upotrebe: Prije svake upotrebe, provjerite da li na svrdlu ima znakova oštećenja, pukotina ili prekomjernog habanja. Ne koristite oštećena svrdla.
- Izbjegavajte pregrijavanje: Tokom duže upotrebe, povremeno ostavite svrdlo da se hladi kako biste spriječili pregrijavanje, što može smanjiti vijek trajanja svrdla.
- Očistite krhotine: The four-flute design helps clear debris, but ensure the work area remains clear of obstructions.
3. Podešavanje
Proper installation of the drill bit is crucial for safe and effective drilling.
- Odaberite ispravan bit: Ensure you are using the DEWALT DW5540 1/2-inch SDS+ drill bit for your specific application.
- Očistite dršku: Wipe the SDS+ shank of the drill bit clean to remove any dust or debris. A small amount of grease can be applied to the shank for smoother insertion and removal, and to reduce wear.
- Insert into Rotary Hammer: Pull back the collar on your SDS+ rotary hammer drill's chuck. Insert the drill bit shank into the chuck until it clicks into place.
- Potvrdite angažman: Release the collar and gently pull on the drill bit to ensure it is securely locked. There will be a small amount of play, which is normal for SDS+ systems.

4. Uputstvo za upotrebu
Follow these steps for optimal performance and longevity of your drill bit.
- Lokacija za označavanje bušenja: Clearly mark the precise location where you intend to drill.
- Pozicionirajte bušilicu: Čvrsto držite rotacijsku bušilicu s obje ruke. Postavite vrh svrdla direktno preko označenog mjesta.
- Započni bušenje: Begin drilling at a low speed to create a pilot indentation, then increase to the appropriate speed for your material. Apply steady, firm pressure. Do not force the drill.
- Održavajte pravi ugao: Keep the drill bit perpendicular to the surface to ensure a straight hole and prevent bit breakage.
- Očistite krhotine: The four-flute design of the DW5540 efficiently removes debris. For deep holes, periodically withdraw the bit slightly to further aid in chip removal.
- Monitor topline: If the bit becomes excessively hot, pause drilling and allow it to cool.
- Complete the Hole: Nastavite sa bušenjem dok se ne postigne željena dubina.
- Izvucite bit: Once the hole is complete, slowly withdraw the drill bit from the hole while the drill is still rotating.

5. Održavanje
Regular maintenance extends the life of your drill bit and ensures consistent performance.
- čišćenje: After each use, clean the drill bit to remove concrete dust and debris. A wire brush can be used for the flutes, and a cloth for the shank.
- podmazivanje: Periodically apply a small amount of SDS+ chuck grease to the shank of the bit to reduce friction and wear in the rotary hammer chuck.
- Skladištenje: Store the drill bit in a dry place to prevent rust. Keep it in its original packaging or a dedicated drill bit case to protect the carbide tip from damage.
- inspekcija: Regularly inspect the carbide tip for chipping or excessive wear. A worn or damaged tip will reduce drilling efficiency and can lead to bit breakage.

6. Otkrivanje problema
Uobičajeni problemi i njihova moguća rješenja:
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Burgija ne reže efikasno | Worn or damaged carbide tip; incorrect drilling speed; insufficient pressure. | Inspect the tip and replace if damaged. Adjust drilling speed and apply steady pressure. |
| Excessive heat from the drill bit | Continuous drilling without cooling; drilling too fast; insufficient debris removal. | Pause drilling to allow the bit to cool. Reduce drilling speed. Periodically withdraw the bit to clear debris. |
| Drill bit stuck in material | Bit binding due to incorrect angle; debris accumulation. | Ensure the drill is held straight. Try to gently rotate and pull the bit. If necessary, use a wrench to carefully turn the bit (ensure drill is off and unplugged). |
| Drill bit not locking into chuck | Debris in chuck; worn chuck; incorrect bit type. | Clean the SDS+ chuck. Ensure the bit is SDS+. If issues persist, the chuck may require service. |
