Fuel Filter Cup Cleaning
The fuel filter cup is a small well underneath the fuel valve. It helps to trap dirt and water that
may be in your fuel tank before it can enter the engine. To clean the fuel filter cup:
1. Turn the fuel valve to the "OFF” position.
2. Unscrew the fuel filter cup from the fuel valve using a wrench. Turn the valve toward you
to unscrew (
see figure 19
).
3. Clean the cup of all sediment. Using a rag or brush.
4. Reinstall the fuel filter cup.

Spark Plug Maintenance
The spark plug is important for proper engine operation. A good spark plug should be intact,
free of deposits, and properly gapped. To inspect you spark plug:
1. Pull on the spark plug cap to remove it.
2. Unscrew the spark plug from the generator using the spark plug wrench included with
this product (see
figure 20
).
3. Visually inspect the spark plug. If it is cracked or chipped, discard and replace with a new
spark plug. We recommend using a F6RTC spark plug such as NGKBPR5ES.
4. Measure the plug gap with a gauge (see
figure 21
). The gap should be 0.7-0.8 nun
(0.028-0.031 in).
