Briggs & Stratton 40248 Oil Recommendations, Checking and Adding Oil, Changing Oil

Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris. Use the same instructions given above for the engine.

CAUTION

Improper treatment of generator can damage it and shorten its life.

•DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.

•DO NOT insert any objects through cooling slots.

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:

*Check oil level frequently at higher temperatures. 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.

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 and Adding Oil

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

1.Make sure unit is on a level surface.

2.Remove roof (see Removable Roof and Battery Access section).

3.Remove oil fill cap/dipstick and wipe clean with cloth.

4.Verify oil level is at the FULL mark on dipstick (Figure 14).

Figure 14 — Oil Fill Range

5.If needed, slowly pour oil into oil fill opening. RECHECK oil level. DO NOT overfill.

6.Replace and tighten dipstick.

7.Replace roof.

Changing Engine Oil and Filter

Remove the two screws from each plastic access cover and remove both access covers from the two sides of the generator enclosure.

Changing Oil

1.Slide oil drain tube from hose clamp and place oil drain tube into approved container.

2.Push in and rotate oil drain fitting 1/4 turn counterclockwise. Slowly pull outward until oil starts draining (Figure 15). DO NOT pull oil drain fitting off.
