Question 7

A pneumatic drill uses compressed air, so it's useful when electricity isn't available (option a). Option b: pneumatic drills aren't for tight small areas (like electric drills with small bits might be). Option c: they're noisy, so not for noise - problem areas. Option d: they aren't for precision work; tools like CNC or small electric drills are better for precision.

A circular saw's upper blade guard is for safety; without it, the exposed blade is dangerous (option b). Option a: trigger lock is separate. Option d: saw kerf width is about blade thickness, not guard. Option c: safety features disabled is not the main reason; the exposed blade is the direct danger.

The upper blade guard on a circular saw is crucial for safety and needs maintenance (option a). Option b: blade sharpness is important but not the most important maintenance related to the guard. Option c: battery charge is for cordless, not the main guard - related maintenance. Option d: lower blade guard is less critical for main maintenance compared to upper.

Answer:

a. when electricity is unavailable
