• Compatibilitate instrument: Ensure the drill bit is compatible with your rotary hammer drill. The DW5540 features an SDS+ shank and is designed for SDS+ chucks only.
• Securizarea piesei de lucru: Always secure the material you are drilling into to prevent movement during operation.
• Inspectați înainte de utilizare: Înainte de fiecare utilizare, verificați burghiul pentru a depista orice semne de deteriorare, crăpături sau uzură excesivă. Nu utilizați burghie deteriorate.
• Evitați supraîncălzirea: Lăsați burghiul să se răcească periodic în timpul utilizării prelungite pentru a preveni supraîncălzirea, care poate reduce durata de viață a burghiului.
• Curățați resturile: The four-flute design helps clear debris, but ensure the work area remains clear of obstructions.
