Question

what should you do with liquid powered tools before refueling them? select the best option. refuel while it is still on turn it off and refuel it right away dump what fuel is left out first turn it off and allow the motor to cool down before refueling

Explanation:

To refuel liquid - powered tools safely, we need to consider safety precautions. Refueling while the tool is on (first option) is dangerous as it can cause fires or other hazards. Turning it off and refueling right away (second option) is not safe because the motor is still hot, which can also lead to fire risks. Dumping the remaining fuel (third option) is unnecessary and wasteful, and also poses safety risks. The correct practice is to turn off the tool and let the motor cool down (fourth option) because a hot motor can ignite the fuel, and cooling it down reduces this risk.

Answer:

D. Turn it off and allow the motor to cool down before refueling
