3.3.3 ENGINE MAINTENANCE


When working on the generator, always
disconnect the spark plug wire from spark plug
and keep wire away from spark plug.

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 (Figure 9).

3.3.5 CHANGING THE OIL

Change the oil after the first 20 hours of operation, then every 50
hours thereafter. If running this unit under dirty or dusty conditions,
or in extremely hot weather, change the oil more often.

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 while the engine
is still warm:
• Clean area around oil drain plug (Figure 12).
• 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 spark plug F6TC, NGK BP6IS or Champioin RN11YC. 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 0.76 mm (0.030 in.). Install the
correctly gapped spark plug into the cylinder head and torque
to 15 ft/lbs. (Figure 13).

3.3.7 SPARK ARRESTOR

The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen at least once each year (Figure 14). If unit is
used regularly, inspect and clean more often.
If using the generator on any forest-covered, brush-covered
or grass-covered unimproved land, it must equipped with a
spark arrestor. The spark arrestor must be maintained in good
condition by the owner/operator.
Clean and inspect the spark arrestor as follows:
• Remove clamp and spark arrestor from muffler.
• Inspect screen and replace if torn, perforated or otherwise
damaged. DO NOT USE a defective screen. If screen is not
damaged, clean it with commercial solvent.
• Replace the spark arrestor and clamp.
