Before a shift, which condition of the bucket and teeth indicates maintenance is needed?

• A. Inspect for wear, cracks, broken welds, missing teeth; replace as needed.
• B. Only look for rust.
• C. Check for hydraulic fluid color.
• D. Verify bucket capacity by weight of soil.

Answer: (A)

This question is about pre-shift inspection signs that indicate the bucket and teeth need maintenance. The best indicator is wear, cracks, broken welds, or missing teeth. These issues directly affect the bucket’s strength and digging effectiveness: worn teeth lose cutting efficiency and can accelerate wear; cracks can propagate under load and fail; broken welds weaken joints and pose a safety risk; missing teeth change load distribution and increase stress on the bucket and linkage. If any of these are present, maintenance or replacement should be done before operation to prevent failure and keep digging performance reliable.

Rust alone isn’t a reliable sole indicator—surface rust can be cosmetic, and deeper corrosion must be evaluated but isn’t by itself a definitive maintenance sign. Checking hydraulic fluid color relates to the hydraulic system, not the bucket’s structural condition. Verifying bucket capacity by soil weight is about workload planning, not the bucket’s physical condition.
