Application Instructions

1. Ensure rotary hammer drill is set to hammer-drill mode for masonry applications
2. Insert SDS-plus shank into the drill chuck until it clicks and locks securely
3. Verify bit is seated correctly with no lateral play
4. Mark drilling position clearly before starting
5. Begin drilling at low speed to establish a starting point before increasing speed
6. Apply steady, even pressure — allow the hammer action to do the work
7. Withdraw the bit periodically to clear debris from the flutes and bore hole
8. Use appropriate dust extraction or respiratory protection when drilling masonry
9. Exercise care when drilling through walls to avoid hidden services
10. Inspect carbide tip for wear or damage before each use — replace if chipped or dull
