3.4.4 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.
3.4.5 CHANGING THE OIL AND OIL FILTER
Change the oil and filter 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:
1. Clean area around oil drain cap.
2. Remove oil drain cap from the drain hose and oil fill plug to
drain oil completely into a suitable container.
3. When oil has completely drained, install oil drain cap and
tighten securely.
4. Place a suitable container beneath the oil filter and turn filter
counterclockwise to remove. Discard according to local
regulations.
5. Coat gasket of new filter with clean engine oil. Turn filter
clockwise until gasket contacts lightly with filter adapter. Then
tighten an additional 3/4 turn.
6. Fill oil sump with recommended oil and replace the oil fill plug.
(See "Before Starting the Generator" for oil recommendations).
7. Wipe up any spilled oil.
8. Dispose of used oil at a proper collection center.
3.4.6 REPLACING THE SPARK PLUG
Use Champion RC14YC 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. To gain access, remove the four (4) socket head screws and
take off the side panel.
3. Clean the area around the spark plug and remove it from the
cylinder head.
4. Set the spark plug's gap to .76 mm (0.030 in.). Install the
correctly gapped spark plug into the cylinder head (Figure 12).
5. Push the boot firmly on the spark plug and install side panel.

3.5 SERVICE AIR FILTER

The engine will not run properly and may be damaged if using a
dirty air filter. Clean or replace the air filter paper filter every 200
hours or once a year (Figure 15). Clean or replace more often if
operating under dusty conditions. To clean or replace paper air
filter:
1. Remove air filter cover and remove paper filter (Figure 13).
2. 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.
3. Clean air filter cover. Next insert new paper filter into the base
of the air filter. Re-install air filter cover.
To order a new air filter (part number 073111), please contact
