TIP: Loctite Anti-Seize applied to the threaded portion of the spark plugs will retard corrosion, making future removal of
the spark plugs easier.
WARNING: Do not remove the spark plugs while the engine is hot. Allow the engine to cool before removing them.
5.4.5 How to Clean the Air Screen/Flame Arrestor
The air screen/flame arrestor should be cleaned after the first 50 hours of operation. Then refer to the
maintenance schedule in this manual.
1. Clean using a good dish washing solution, rinse, and air dry.
2. Inspect the seal edges. If worn, install a new flame arrestor.

WARNING: The generator should never be started/operated without the air screen/flame arrestor properly installed.
5.4.6 How to Check the Engine Oil Pressure
The engine oil pressure is continuously monitored by the ECU and the generator control panel when the
engine is running. Should the oil pressure fall below a safe operating level, the generator shuts down and the
control panel low oil pressure fault LED illuminates. If this occurs, follow these steps:
1. Do not attempt to restart the generator.
2. Check the oil level and the condition of the oil.
3. If there is a loss of oil:
a. Inspect the engine for leaks.
b. Inspect the wire connections at the oil pressure sender and oil pressure switch.
