Question

wheel grinders need be equipped with a(n):

• machine guard
• cautionary sign
• operations manual
• fabric cover

Explanation:

Wheel grinders are power tools, and for safety during operation, they must be equipped with a machine guard to protect users from flying debris, wheel breakage, etc. A cautionary sign is a warning but not a physical safety device for the machine itself, an operations manual is for instructions (not a required equipment for safety during use), and a fabric cover is not a standard safety equipment for wheel grinders.

Answer:

A. Machine guard
