20 multiple choice 1 point
when would the use of an air tool be inappropriate?
when rotating tires
when doing an oil change.
when removing a valve cover
when replacing suspension components

Explanation:

1. For the first question, draining the water from an air - compressor at the end of each day helps prevent corrosion and damage. Turning off the emergency shut - off is not a daily routine when just powering down, changing oil and retorquing mounting bolts are not daily tasks either.
2. For the second question, an oil change typically involves using wrenches and other hand tools in a more controlled environment and doesn't require high - power air tools. Air tools are commonly used for rotating tires (impact wrenches), removing valve covers (if bolts are tight), and replacing suspension components (for loosening and tightening bolts).

Answer:

1. Drain the water
2. When doing an oil change.
