MAINTENANCE & CARE

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 the 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
and unscrew (See Figure 12).
3. Clean the cup of all sediments using a rag or brush.
4. Reinstall the fuel filter cup.

SPARK PLUG MAINTENANCE

Spark plug: Torch F5RTC
The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits,
and properly gapped. Refer to Recommended Maintenance Schedule in Figure 9. To inspect the spark plug:
1. Remove spark plug boot. Be careful not to tear insulation or wire.
2. Unscrew the spark plug from the engine using the spark plug wrench provided. There is limited space for the
wrench to turn. Use both rows of holes in the spark plug wrench to gain leverage to loosen the plug.
3. Visually inspect the spark plug for cracks or excessive electrode wear. Replace as necessary.
4. Measure the plug gap with a wire gauge. The gap should be 0.7 to 0.8 mm (0.028-0.031 in).
5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base then re-gap the
spark plug.
6. Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten spark
plug. Recommended tightening of spark plug is ½ to ¾ of a turn after spark plug gasket contacts spark plug hole.
Reinstall the spark plug boot.
OIL FILTER MAINTENANCE
Every 250 hours of use, make sure to change out your oil filter. The oil
filter can be found on the back of the generator at the base of the engine, as
shown in figure 13.
