General Information

This manual contains safety information to make you aware of the hazards and risks associated with engines and how to avoid them. It also contains instructions for the proper use and care of the engine. Because Briggs & Stratton Corporation does not necessarily know what equipment this engine will power, it is important that you read and understand these instructions and the instructions for the equipment. Save these original instructions for future reference.

For replacement parts or technical assistance, record below the engine model, type, and code numbers along with the date of purchase. These numbers are located on your engine (see the Features and Controls page).

Date of purchase:

MM/DD/YYYY

Engine model:

Model: Type: Code:

Look for the 2D barcode located on some engines. When viewed with a 2D--capable device, the code will bring up our website where you can access support information for this product. Data rates apply. Some countries may not have online support information available.

Power Ratings: The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque values are derived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken with exhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine power will be higher than net engine power and is affected by, among other things, ambient operating conditions and engine--to--engine variability. Given the wide array of products on which engines are placed, the gasoline engine may not develop the rated gross power when used in a given piece of power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine--to--engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this engine.

How To Change The Oil - Figure 11 12 13

Used oil is a hazardous waste product and must be disposed of properly. Do not discard with household waste. Check with your local authorities, service center, or dealer for safe disposal/recycling facilities.

Remove Oil

1.With engine off but still warm, disconnect the spark plug wire (A) and keep it away from the spark plug (Figure 11).

2.Remove the oil drain plug (B, Figure 12). Drain the oil into an approved receptacle. Note: Any of the oil drain plugs shown below may be installed in the engine.

3.After the oil has drained, install and tighten the oil drain plug.

Add oil

Place engine level.

Clean the oil fill area of any debris.

See the Specifications section for oil capacity.

Models with oil fill cap

1.Remove the oil fill cap (D, Figure 12).

2.Pour the oil slowly into the engine oil fill (E). Fill to point of overflowing.

3.Replace and tighten the oil fill cap.

Models with short dipstick

1. Remove the dipstick (F, Figure 12) and wipe with a clean cloth.

*In dusty conditions or when airborne debris is present, clean more often.
