CHANGING ENGINE OIL
n
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeat-
ed skin exposure with used oil. Thoroughly
wash exposed areas with soap.
Refer to the Service Schedule for engine oil and filter change fre-
quencies.
Drain the oil while the engine is still warm from running. This
means warm up the engine, shut it down and drain immediately
as follows:
1. Remove the drain hose from its retaining clip or cut the zip-tie
securing the oil drain hose.
2. Loosen and remove OIL DRAIN HOSE CAP. Drain oil com-
pletely into suitable container.
3. When all oil has drained, install and tighten OIL DRAIN HOSE
CAP and secure drain hose with a new zip-tie, or place the
hose in its retaining clip.
4. Turn OIL FILTER (Figure 10.1) counterclockwise and remove.
Properly dispose of old filter.
5. Apply light coating of new engine oil to seal of new oil fil-
ter. Install FILTER and tighten by hand only. DO NOT OVER
TIGHTEN.
6. Remove OIL FILL CAP and add recommended oil. Crankcase
oil capacity is listed in the "Specifications" section.
n
After refilling the crankcase with oil, always
check oil level on dipstick. NEVER OPERATE
ENGINE WITH OIL BELOW THE DIPSTICK “ADD”
MARK.
7. Start engine and check for oil leaks.
8. Shut OFF engine and wait 10 minutes for the oil to settle down
into the oil pan. Recheck oil level on dipstick. DO NOT fill
above the dipstick "FULL" mark.
9. Dispose of used oil at a proper collection center.
COOLING INTAKE/OUTLET
Air intake and outlet openings in the generator compartment must
be open and unobstructed for continued proper operation. This
includes such obstructions as high grass, weeds, brush, leaves
and snow.
Without sufficient cooling and ventilating air flow, the engine/gen-
erator quickly overheats, which causes it to shut down. (See the
installation diagram.)
The exhaust system parts from this product get
extremely hot and remains hot after shutdown.
High grass, weeds, brush, leaves, etc. must
remain clear of the exhaust. Such materials may
ignite and burn from the heat of the exhaust
system.
INSPECT COOLING SYSTEM
Inspect engine cooling system. See the Service Schedule.•
Check hoses for damage, deterioration, leaks, etc. Correct any •
discrepancies found.
Check hose clamps for tightness.•
