3.3.2 TO CLEAN THE GENERATOR
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
• A vacuum cleaner may be used to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi) may be used to blow
away dirt. Inspect cooling air slots and openings on the generator.
These openings must be kept clean and unobstructed.
3.3.3 ENGINE MAINTENANCE
When working on the generator, always disconnect

negative cable from battery. Also disconnect 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.
3.3.5 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. You will need Oil Filter Part
No. 070185B.
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.

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.

(See "Before Starting the Generator" for oil recommendations).
7. Wipe up any spilled oil.
8. Dispose of used oil at a proper collection center.
3.3.6 REPLACING THE SPARK PLUG
Use Champion RC14YC spark plug or equivalent. Replace the
plug every 200 hours. This will help the engine start easier and
run better.

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

3.4 SERVICE AIR CLEANER
The engine will not run properly and may be damaged if using a

if operating under dusty conditions. To clean or replace paper air
filter:
1. Remove air cleaner cover and remove paper filter (Figure 14).
