Look the tool over before you pull the trigger: housing, guards, cord, plug. Four things, every time.
A tool with a cracked housing or a missing guard is not less safe, it is unguarded. It does the same work right up to the moment it does something else.
It is a four-item list and it takes seconds. Housing: cracks, missing screws, anything that exposes the inside. Guards: present and working, not wired back or removed. Cord: the whole length, not just the end you can see. Plug: pins straight, nothing loose, the grounding pin still there if it is supposed to be.
Check yourself: The guard is missing but you know how to hold the tool safely. Proceed?
Answer: No. A missing guard is a reason to stop, not a reason to be extra careful.
The guard is there for the moment your attention is elsewhere or something unexpected happens. Care substitutes for it exactly until the moment the guard would have mattered.
