Code 1300 is LOW OIL PRESSURE, shown with a red LED: the low oil pressure sensor triggered a shutdown because of inadequate oil. Generac says the cause is typically low oil from oil consumption, leaks or a lack of maintenance, and that your options are limited beyond basic checks and one attempt to clear the alarm and restart.

0 of 4 completedCapture the exact state
ReversibleLeave the code visible, record the run hours and note when the unit stopped and whether it had been running for a long stretch.
Separate the likely fault domains
ReversibleLet the generator cool for at least 30 minutes. Confirm the dipstick is fully inserted and that the oil fill cap, oil drain cap and oil filter are hand-tightened (righty-tight, lefty-loose), because a loose one can leak. Check the oil level with the dipstick as the owner's manual directs and inspect visible areas for oil leaks; if you see one, clean it up first and dispose of used oil under national, state or local rules.
Correct only the proven, accessible condition
ReversibleAdd only the specified oil when the measured level is low. Do not overfill. Then clear the alarm: on an Evolution controller press OFF, ENTER twice, then AUTO, and on a Power Zone 200 controller hold the OFF button for 3 seconds. An alarm can be a one-time event, so Generac says clearing it and restarting is sometimes all that is needed.
Verify once before going farther
ReversibleNever start the generator while it is under load. If the unit runs continuously for extended periods, Generac says it must be shut down every 24 hours for at least 30 minutes to cool and to have the oil level checked.
