2. सुरक्षा जानकारी
Always prioritize safety when operating power tools and accessories. Failure to follow safety guidelines can result in serious injury.
- व्यक्तिगत सुरक्षा उपकरण (PPE) लगाउनुहोस्: Always wear safety glasses, hearing protection, and a dust mask when drilling. Gloves are recommended for grip and protection.
- उपकरण अनुकूलता: Ensure the drill bit is compatible with your rotary hammer drill. The DW5540 features an SDS+ shank and is designed for SDS+ chucks only.
- सुरक्षित कार्यपिका: Always secure the material you are drilling into to prevent movement during operation.
- प्रयोग गर्नु अघि निरीक्षण गर्नुहोस्: Before each use, inspect the drill bit for any signs of damage, cracks, or excessive wear. Do not use damaged bits.
- अत्याधिक तातोबाट बच्नुहोस्: Allow the drill bit to cool periodically during extended use to prevent overheating, which can reduce bit life.
- खाली मलबे: The four-flute design helps clear debris, but ensure the work area remains clear of obstructions.
3. सेटअप
Proper installation of the drill bit is crucial for safe and effective drilling.
- सही बिट छान्नुहोस्: Ensure you are using the DEWALT DW5540 1/2-inch SDS+ drill bit for your specific application.
- शङ्क सफा गर्नुहोस्: 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.
- संलग्नता प्रमाणित गर्नुहोस्: 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. सञ्चालन निर्देशनहरू
Follow these steps for optimal performance and longevity of your drill bit.
- Mark Drilling Location: Clearly mark the precise location where you intend to drill.
- ड्रिललाई राख्नुहोस्: Hold the rotary hammer drill firmly with both hands. Position the tip of the drill bit directly over the marked spot.
- ड्रिलिंग सुरु गर्नुहोस्: 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.
- Maintain Straight Angle: Keep the drill bit perpendicular to the surface to ensure a straight hole and prevent bit breakage.
- खाली मलबे: The four-flute design of the DW5540 efficiently removes debris. For deep holes, periodically withdraw the bit slightly to further aid in chip removal.
- गर्मी मनिटर: If the bit becomes excessively hot, pause drilling and allow it to cool.
- प्वाल पूरा गर्नुहोस्: वांछित गहिराई पुगेसम्म ड्रिलिंग जारी राख्नुहोस्।
- Withdraw the Bit: Once the hole is complete, slowly withdraw the drill bit from the hole while the drill is still rotating.

5. मर्मतसम्भार
Regular maintenance extends the life of your drill bit and ensures consistent performance.
- सरसफाई: 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.
- स्नेहन: 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.
- भण्डारण: 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.
- निरीक्षण: 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.

T. समस्या निवारण
सामान्य समस्याहरू र तिनीहरूका सम्भावित समाधानहरू:
| समस्या | सम्भावित कारण | समाधान |
|---|---|---|
| Drill bit not cutting efficiently | 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. |
