3.3.4 CHECKING OIL LEVEL
See the “Before Starting the Generator” section for information on
checking the oil level. The oil level should be checked before each
use, or at least every eight hours of operation. Keep the oil level
maintained.
3.3.5 CHANGING THE OIL
Change the oil after every 100 hours. If running this unit under
dirty or dusty conditions, or in extremely hot weather, change the
oil more often.
n
Hot oil may cause burns. Allow engine to
cool before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
Use the following instructions to change the oil after the engine
cools down:
Clean area around oil drain plug.•
Remove oil drain plug from engine and oil fill plug to drain oil •
completely into a suitable container.
When oil has completely drained, install oil drain plug and •
tighten securely.
Fill engine with recommended oil. (See “Before Starting the •
Generator” for oil recommendations).
Wipe up any spilled oil.•
Dispose of used oil at a proper collection center.•
3.3.6 REPLACING THE SPARK PLUG
Use Champion N9YC spark plug or equivalent. Replace the plug
once each year. This will help the engine start easier and run
better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug into the cylinder head
(Figure 11).

3.5 VALVE CLEARANCE
Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008" inches)•
Exhaust — 0.0020 ± 0.02mm (cold) (0.008" ± 0.0008" •
inches)
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to ensure longest life for the engine.
