MAINTENANCE OWNER/
OPERATOR CAN PERFORM
CHECK ENGINE OIL LEVEL
Refer to the “Checking Fluid Levels” section.
CHECK BATTERY
Check battery fluid level each week as outlined under “Check •
Fluid Levels”.
Check battery cables for condition, tightness, corrosion or dam- •
age. Clean, tighten or replace as necessary.
EXERCISE SYSTEM
Start the generator engine at least once every seven days and let it
run at least 20 minutes. See the “Weekly Exercise Cycle” section.
INSPECT COOLING SYSTEM
Inspect engine cooling system at least once each month. •
Check hoses for damage, deterioration, leaks, etc. Correct any •
discrepancies found.
Check hose clamps for tightness. •
CHECK ENGINE COOLANT LEVEL
See the “Checking Fluid Levels” section.
PERFORM VISUAL INSPECTION
Complete a thorough visual inspection of the entire engine-genera-
tor monthly. Look for obvious damage, loose, missing or corroded
nuts, bolts and other fasteners. Look for fuel, oil or coolant leaks.
INSPECT EXHAUST SYSTEM
Inspect the exhaust system at least once every three months.
Check all exhaust system pipes, mufflers, clamps, etc. for condi-
tion, tightness, leaks, security, damage.
CHECK FAN BELT
Inspect fan belts every three months. Replace any damaged, •
deteriorated, worn or otherwise defective belt.
Check fan belt tension. Thumb pressure, exerted midway •
between pulleys, should deflect about 3/8 to 5/8 inch. Adjust
belt tension as required.
INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
n
Do not attempt to adjust the governor. Only
qualified service facilities should adjust
the governor. Excessively high operating
speeds are dangerous and increase the
risk of personal injury. Low speeds impose
a heavy load on the engine when adequate
engine power is not available and may
shorten engine life. Correct rated frequency
and voltage are supplied only at the proper
governed speed. Some connected electrical
load devices may be damaged by incorrect
frequency and/or voltage. Only qualified ser-
vice technicians should adjust the governed
speed.
CHANGING ENGINE OIL
Refer to maintenance performed by authorized service facilities for
engine oil and filter change frequencies.
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 OIL DRAIN HOSE from its retaining clip.
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 re-install into its retaining clip.
4. Turn OIL FILTER (Figure 10.2) counterclockwise and remove.
Dispose of old filter.
5. Apply light coating of new engine oil to seal of new oil
filter.-Install FILTER and tighten by hand only. DO NOT
OVERTIGHTEN.
6. Remove OIL FILL CAP. Add recommended oil (see
SPECIFICATIONS). DO NOT FILL ABOVE THE DIPSTICK
“FULL” MARK. Crankcase oil capacity is 4.0 U.S. quarts (3.8
liters).
