Fuel Valve Maintenance

The fuel valve is equipped with a fuel sediment cup, screen, retaining ring and o-ring that need to be cleaned every 100 hours or once a year (whichever occurs first).

1.Move fuel valve to “Off” position.

2.Remove sediment cup (A) from fuel valve. Remove o-ring (B), retaining ring (C) and screen (D) from fuel valve.

3.Wash sediment cup, o-ring, retaining ring, and screen in a nonflammable solvent. Dry them thoroughly.

4.Place screen, retaining ring, and o-ring into fuel valve. Install sediment cup and tighten securely.

5.Move fuel valve to “On” position, and check for leaks. Replace o-ring if there is any leakage.

Engine Maintenance

WARNING Unintentional sparking can result in fire or electric shock.

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.

Oil Recommendations

We recommend the use of Briggs & Stratton Warranty Certified oils for best performance. Other high-quality detergent oils are acceptable if classified for service SF, SG, SH, SJ or higher. DO NOT use special additives.

Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.

*Below 40°F (4°C) the use of SAE 30 will result in hard starting.

**Above 80°F (27°C) the use of 10W30 may cause increased oil consumption. Check oil level more frequently.

NOTICE 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.

Checking Oil Level

Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil level maintained.

1.Make sure generator is on a level surface.

2.Clean area around oil fill, remove oil cap/dipstick and wipe dipstick with clean cloth. Replace dipstick. Remove and and check oil level.

NOTICE DO NOT screw in dipstick when checking oil level.

3.Verify oil is at “Full” mark (E) on dipstick. Replace and tighten oil cap/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.

NOTICE Overfilling with oil may cause the engine to not start, or hard starting.

•DO NOT overfill.

•If over the FULL mark on dipstick, drain oil to reduce oil level to FULL mark on dipstick.

4.Replace and tighten oil cap/dipstick.
