Maintenance
18 Instruction Manual for Portable Generator
• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft bristle brush to loosen caked on dirt, oil, etc.
• Use a vacuum 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
generator. These openings must be kept clean and unob-
structed.
DO NOT use a garden hose to clean
generator. Water can enter engine fuel
system and cause problems. If water enters generator
through cooling air slots, some water will be retained in
voids and crevices of rotor and stator winding insulation.
Water and dirt buildup on generator internal windings will
decrease insulation resistance of windings.
Engine Maintenance
Accidental start-up. Disconnect spark
plug wires when working on unit. Fail-
ure to do so could result in death or serious injury.
Engine Oil Recommendations
All oil should meet minimum American Petroleum Insti-
tute (API) Service Class SJ, SL or better. Use no special
additives. Select the oil's viscosity grade according to the
expected operating temperature (also see chart).
• Above 40° F, use SAE 30
• Below 40° F and down to 10° F, use 10W-30
• All temperatures, use synthetic 5W-30
Use petroleum based oil for engine break-in (30 hours)
before using synthetic oil.
Any attempt to crank or start the
engine before adding the recom-
mended type and quantity of engine oil can result in
engine damage.
Inspect engine oil level prior to each use, or every 8
hours of operation.
1. Place generator on a level surface.
2. Clean area around oil fill.
3. Remove oil fill cap and wipe dipstick clean.
4. Screw dipstick into filler neck. Verify oil level is within safe
operating range as shown.
5. Add recommended engine oil as necessary.
6. Replace oil fill cap and hand-tighten.
Some units have more than one oil fill
location. It is only necessary to use one
oil fill point.
Change Engine Oil
Accidental start-up. Disconnect spark
plug wires when working on unit. Fail-
ure to do so could result in death or serious injury.
When using generator under extreme, dirty, dusty condi-
tions, or in extremely hot weather, change oil more fre-
quently.
Don’t pollute. Conserve resources.
Return used oil to collection centers.
Change oil while engine is still warm from running, as fol-
lows:
1. Place generator on a level surface.
2. Disconnect the spark plug wire from the spark plug and
place the wire where it cannot contact spark plug.
3. Clean area around oil fill, and oil drain plug.
4. Remove oil fill cap and wipe dipstick clean.
5. Remove oil drain plug and drain oil completely into a suit-
able container.
6. Install oil drain plug and tighten securely.
7. Slowly pour oil into oil fill opening until oil level is between L
and H marks on dipstick. DO NOT overfill.
8. Install oil fill cap, and hand-tighten.
9. Wipe up any spilled oil.
10. Properly dispose of oil in accordance with all applicable reg-
ulations.
