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:

When dealing with liquid - powered tools, safety is crucial. Refueling while the tool is on is extremely dangerous as it can cause fuel spills and potential fires due to the heat and movement of the running tool. Turning it off and refueling right away might still be risky if the motor is hot, as some fuels are flammable and can ignite with a heat source. Dumping the remaining fuel is wasteful and not a standard safety practice. However, turning it off and allowing the motor to cool down before refueling is a safe practice. This reduces the risk of fuel vapors igniting from a hot motor.

Answer:

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