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.

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.

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 dipstick, remove oil dipstick and wipe dipstick with clean cloth. Insert dipstick firmly, then remove and check oil level.

3.Verify oil is at “Full” mark on dipstick. Insert dipstick firmly before starting engine.

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, remove oil fill cap and 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 both the oil fill cap and dipstick.
