• Use low pressure air (not to exceed 25 psi) to blow
away dirt. Inspect cooling air slots and openings on the
generator.These openings must be kept clean and
unobstructed.

Oil
Oil Recommendations
NOTE: When adding oil to the engine crankcase, use only
high quality detergent oil classified “For Service SF, SG, SH,
SJ” or higher. DO NOT use special additives.
1. Choose a viscosity according to the following table:
NOTE: Synthetic oil meeting ILSAC GF-2,API certification
mark and API service symbol with “SJ/CF ENERGY
CONSERVING” or higher, is an acceptable oil at all
temperatures. Use of synthetic oil does not alter required
oil change intervals.
SAE 30: 40 °F and higher (5 °C and higher) is good for all
purpose use above 40°F, use below 40°F will cause hard
starting.
10W-30: 0 to 100 °F (-18 to 38 °C) is better for varying
temperature conditions.This grade of oil improves cold
weather starting, but may increase oil consumption at
80°F(27°C) or higher.
*Check oil level frequently at higher temperatures.
Synthetic 5W-30: -20 to 120 °F (-30 to 40 °C) provides
the best protection at all temperatures as well as improved
starting with less oil consumption.
5W-30: 40 °F and below (5 °C and below) is recommended
for winter use, and works best in cold conditions.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 5 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Remove oil dipstick and wipe dipstick with clean cloth.
Replace and tighten dipstick. Remove and and check oil
level.
3. Verify oil is at “Full” mark on dipstick. Replace and
tighten dipstick.
Adding Engine Oil
1. Make sure generator is on a level surface.
2. Check oil level as described in “Checking Oil Level”.
3. If needed, slowly pour oil into oil fill opening to the
“Full” mark on dipstick. DO NOT overfill.
4. Replace and tighten dipstick.
Servicing Air Cleaner
Your engine will not run properly and may be damaged if
you run it with a dirty air cleaner.
Replace the air cleaner every 25 hours of operation or
once each year, whichever comes first. Replace more often
if operating under dirty or dusty conditions.
• DO NOT expose generator to excessive moisture, dust, dirt,
or corrosive vapors.
• DO NOT insert any objects through cooling slots.
Improper treatment of generator can damage it and
shorten its life.
CAUTION
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR
GENERATOR
• Disconnect the spark plug wire from the spark plug and place
the wire where it cannot contact spark plug.
WHEN TESTING FOR ENGINE SPARK
• Use approved spark plug tester.
• DO NOT check for spark with spark plug removed.
Unintentional sparking can result in fire or
electric shock.
