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
DANGER
When working on the generator, always
disconnect negative cable from battery. Also
disconnect spark plug wires 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.
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.
NOTE:
Whenever possible, run engine for approximately 5 minutes to
get the engine oil hot. This will aid in draining the oil.
Use the following instructions to change the oil while the engine
is still warm:
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.
Place a suitable container beneath the oil filter and turn •
filter counterclockwise to remove. Discard according to local
regulations.
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.
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
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) Torx screws "T27" and
take off 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
14).
5. Push the boot firmly on the spark plug and install side panel.
