IMPORTANT USAGE & CARE GUIDE FOR CARBIDE TOOLS
- Uniform Surface Contact: Always strike lightly, ensuring the entire carbide-tipped face makes even, uniform contact with the stone. Avoid striking too hard, as excessive force can cause the delicate carbide points to chip.
- Full-Face Strike Alignment: Always ensure the entire face hits flat against the stone. Striking at an angle (hitting on points or corners only) will cause the delicate carbide tips to chip.
- Delicate Nature of Carbide: Carbide products are extremely hard yet brittle and sensitive to impact shock. Please handle with care.
- Note on Chipping: Due to the nature of multi-point carbide tools, improper striking angles or excessive force may cause minor chipping along the tips. This is a normal characteristic of high-hardness bush hammers and is not considered a product defect.
- Storage: Wipe away dust, moisture, and debris immediately after use. Store in a dry location.
