Optional May not apply

This may not apply to you. You have not answered "Requirement 4: which machine job?" yet. Answer it and this step will either settle or drop off.

For any engine-powered machine: include the engine coolant, engine oil, hydraulic and/or transmission fluid, and battery voltage (using a voltmeter). Then conduct a preoperational check of that machine with it.

Note. Two halves: create the checklist, then use it to conduct the preoperational check. Battery voltage is checked with a voltmeter.
