CAUTION
To prevent starter motor damage, do not attempt to start the engine for more than 10
seconds continuously. If the engine does not start within 10 seconds, wait at least 1 minute
to allow starter motor to cool before starting again. Failure to comply may result in damage
to equipment.
NOTE
Extended engine starter engaging will result in starter drop-out and generate a
starter engagement time fault.
After starting, engine accelerates to 1,600 rpm during warm up. Discharge air
