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).

WARNING

Certain components in this product and its related accessories contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Wash hands after handling.

WARNING

The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

Power Rating

The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002--05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. 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 gas 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

WARNING

Briggs & Stratton does not approve or authorize the use of these engines on 3-wheel All Terrain Vehicles (ATVs), motor bikes, fun/recreational go-karts, aircraft products, or vehicles intended for use in competitive events. Use of these engines in such applications could result in property damage, serious injury (including paralysis), or even death.

WARNING

Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go.

Broken bones, fractures, bruises or sprains could result.

When starting engine, pull the starter cord slowly until resistance is felt and then pull rapidly to avoid kickback.

Remove all external equipment/engine loads before starting engine.

Direct-coupled equipment components such as, but not limited to, blades, impellers, pulleys, sprockets, etc., must be securely attached.

WARNING

Gaseous fuels are extremely flammable and readily form explosive air-vapor mixtures at ambient temperatures.

Do not start the engine.

Do not actuate any electrical switches.

Do not use a phone in the vicinity.

Evacuate the area.

Contact the gas supplier or fire department.

WARNING

Rotating parts can contact or entangle hands, feet, hair, clothing, or accessories.

Traumatic amputation or severe laceration can result.

Operate equipment with guards in place.

Keep hands and feet away from rotating parts.

Tie up long hair and remove jewelry.

Do not wear loose-fitting clothing, dangling drawstrings or items that could become caught.

WARNING

Wear eye protection when doing repair work.

Frostbite can result from skin/eye contact with leaking LP liquid.

Installation, adjustment and repair work should be done by a qualified technician.

Regularly check flexible supply line. Make sure they are in good condition. Replace damaged or leaking components.

Fuel Recommendations

WARNING

Missing or inoperative “fuel lock-off” valve can cause a fire or explosion.

Do not operate the equipment if the “fuel lock-off” valve is missing or inoperative.

Fuel must meet these requirements:

Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems.

In engines set up to run on LPG, commercial grade HD5 LPG is recommended. Recommended fuel composition is fuel with a minimum fuel energy of 2500 BTU’s/ft3 with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%.

NG or LPG engines are certified to operate on natural or liquid propane gas. The emissions control system for this engine is EM (Engine Modifications).

WARNING: The equipment on which this engine is mounted is equipped

with an automatic safety gas “fuel lock-off” valve. Do not operate the equipment if the “fuel lock-off” valve is missing or inoperative.

Oil Recommendations

How To Add Fuel

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,

Inspect Muffler And Spark Arrester - Figure 5

WARNING

Running engines produce heat. Engine parts, especially muffler, become extremely hot.

Severe thermal burns can occur on contact.

Combustible debris, such as leaves, grass, brush, etc. can catch fire.

Allow muffler, engine cylinder and fins to cool before touching.

Remove accumulated debris from muffler area and cylinder area.

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 5) 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.

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.

How To Service The Air Filter - Figure 6

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

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.

See the Maintenance Chart for service requirements.

1.Open the latches (A) and remove the cover (B). See Figure 6.

2.Remove the nut (D) and the retainer (E)..

3.Remove the air filter (F).

4.Remove the pre-cleaner (G), if equipped, from the air filter.

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

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

7.Assemble the dry pre-cleaner to the air filter.

8.Install the air filter and secure with retainer and nut.

9.Install and secure the cover.
