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:
1. Clean area around oil drain plug (Figure 12).
2. Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
3. When oil has completely drained, install oil drain plug and
tighten securely.
4. Fill engine with recommended oil. (See "Before Starting the
Generator" for oil recommendations.)
5. Wipe up any spilled oil.
6. Dispose of used oil at a proper collection center.

3.3.6 REPLACING THE SPARK PLUG
Use spark plug F6TC, NGK BP6IS or Champion 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:
1. Remove clamp and spark arrestor from muffler.
2. 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.
3. Replace the spark arrestor and clamp.

dirty air filter. Clean the air filter every 25 hours (Figure 15). Clean
or replace more often if operating under dusty conditions (Part No.
0H33750219.
1. Remove air filter cover.
