3.3.5 CHANGING THE OIL

Change the oil after the first 30 hours of operation. Change the
oil every 100 hours or every season 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 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 oil sump 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

See Engine Specifications for recommended spark plug. 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 14).

3.3.7 BATTERY REPLACEMENT

The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank the
engine, plug in the 12V charger included in the accessory box
(see the Charging a Battery section). RUNNING THE GENERATOR
DOES NOT CHARGE THE BATTERY. The part number for this
battery is 0G9449.

3.4 SERVICE AIR CLEANER

The engine will not run properly and may be damaged if using
a dirty air cleaner. Clean or replace the air cleaner paper filter
once a year. Clean or replace more often if operating under dusty
conditions (Figure 16). The air filter part number is 0G84420151.
To clean or replace paper air filter:
• Remove air cleaner cover and remove paper filter.
• Clean paper filter by tapping it gently on a solid surface. If the
filter is too dirty, replace it with a new one. Dispose of the old
filter properly.
• Clean air cleaner cover, then insert new paper filter into the base
of the air cleaner. Re-install air cleaner cover.
