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).

Fuel Recommendations

 

 

 

 

 

 

 

 

 

 

 

 

 

Engines give off carbon monoxide, an odorless, colorless, poison gas.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Breathing carbon monoxide can cause nausea, fainting or death.

Fuel must meet these requirements:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Start and run engine outdoors.

Clean, fresh, unleaded gasoline.

 

 

 

 

 

 

 

 

 

A minimum of 87 octane/87 AKI (91 RON). High altitude use, see below.

 

 

 

 

Do not start or run engine in enclosed area, even if doors or windows are open.

Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary

 

 

butyl ether) is acceptable.

NOTICE: This engine was shipped from Briggs & Stratton without oil. Before you start

Determine The Starting System

Before starting the engine, you must determine the type of starting system that is on your engine. Your engine will have one of the following types.

ReadyStart® System: This features a temperature controlled automatic choke. It does not have a manual choke or a primer.

Choke System: This features a choke to be used for starting in cool temperatures. Some models will have a separate choke control while others will have a combination choke/throttle control. This type does not have a primer.

To start your engine, follow the instructions for your type of starting system.

Note: Some engines and equipment have remote controls. See the equipment manual for location and operation of remote controls.

It is a violation of California Public Resource Code, Section 4442, to use or operate the engine on any forest-covered, brush-covered, or grass-covered land unless the exhaust system is equipped with a spark arrester, as defined in Section 4442, maintained in effective working order. Other states or federal jurisdictions may have similar laws. Contact the original equipment manufacturer, retailer, or dealer to obtain a spark arrester designed for the exhaust system installed on this engine.
Remove accumulated debris from muffler area and cylinder area. Inspect the muffler (A, Figure 8) for cracks, corrosion, or other damage. Remove the spark arrester (B), if equipped, and inspect for damage or carbon blockage. If damage is found, install replacement parts before operating.

How To Change The Oil - Figure 2 9 10 11

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

If you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel can leak out and result in a fire or explosion.

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

Drain the oil from the bottom drain hole or from the top oil fill tube.

1.With engine off but still warm, disconnect the spark plug wire (A) and keep it away from the spark plug (Figure 9).

2.Remove the oil drain plug (B, Figure 10). Drain the oil into an approved container. 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.

4.If you drain the oil from the top oil fill tube (C), keep the spark plug end of the engine (D) up (Figure 11). Drain the oil into an approved container.

** Not required unless engine performance problems are noted.

How To Service The Air Filter - Figure 12 13

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

WARNING: Replacement parts must be of the same design and installed

in the same position as the original parts. Other parts may not perform as well, may damage the unit, and may result in injury.

Never start or run the engine with the air cleaner assembly (if equipped) or the air filter (if equipped) removed.

NOTICE: Do not use pressurized air or solvents to clean the filter. Pressurized air can damage the filter and solvents will dissolve the filter.

Two types of air filter systems are shown, a Standard and a High Capacity. Determine the type installed on your engine and service as follows.

Standard Air Filter - Figure 12

The air cleaner system uses a foam element that can be washed and reused.

1. Move the slide lock (A) to the unlock position. Open the cover (B). See Figure 12.

8

BRIGGSandSTRATTON.COM

2.Remove the foam element (C).

3.Wash the foam element in liquid detergent and water. Squeeze dry the foam element in a clean cloth.

4.Saturate the foam element with clean engine oil. To remove the excess engine oil, squeeze the foam element in a clean cloth.

5.Install the foam element into the air filter base.

6.Close the cover and move the slide lock to the locked position.

High Capacity Air Filter - Figure 13

The air cleaner system uses a pleated filter with an optional pre-cleaner. The pre-cleaner can be washed and reused.

1.Loosen the fastener (A) that holds the cover (B). Remove the cover. See Figure 13.

2.Remove the pre-cleaner (C) and the filter (D).

3.To loosen debris, gently tap the filter on a hard surface. If the filter is excessively dirty, replace with a new filter.

4.Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air dry. Do not oil the pre-cleaner.

5.Assemble the dry pre-cleaner to the filter.

6.Install the filter and pre-cleaner into the base (E). Make sure filter fits securely in the base.

7.Install air filter cover and secure with fastener. Make sure the fastener is tight.

Fuel System

Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs & Stratton FRESH START® fuel stabilizer, available as a liquid additive or a drip concentrate cartridge.

There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel system. The engine and fuel can then be stored up to 24 months.

If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.

Engine Oil

While the engine is still warm, change the engine oil. See the How To Change The Oil section.

NOTICE: Store the engine level (normal operating position). If the engine is tipped for storage, the fuel tank must be empty and the spark plug side must be up. If the fuel tank is not empty and if the engine is tipped in any other direction, it may be difficult to start due to oil or gasoline contaminating the air filter and/or the spark plug.
