Final answer:
The question pertains to the procedure for operating an Engine Starter Operation, where you turn the ignition 'on' to engage the starter, and 'off' if the engine does not start to avoid damage to the starter motor.
Step-by-step explanation:
The phrase "(Engine starter) _____ on, _____ off for 1st attempt" appears to relate to the procedure for operating a vehicle's or machine's engine starter system. When initiating the first attempt to start an engine, the typical procedure is to turn the ignition switch to the 'on' position to engage the starter motor and then to 'off' if the engine does not start.
This could be part of a safety procedure or a troubleshooting step for ensuring that the starter motor is not damaged due to consecutive or prolonged attempts. It's important to follow the manufacturer's instructions for starting procedures to prevent damage to the engine or starter system.
Starter motors are typically designed to crank the engine for short periods, with rest intervals if the engine does not start immediately.
