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

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.

If the oil level is low, add the proper amount of oil. Start the engine and make sure the warning light (if equipped) is not activated.

If the oil level is not low, do not start the engine. Contact an Authorized Briggs & Stratton Dealer to have the the oil problem corrected.

Fuel Recommendations

Fuel must meet these requirements:

Clean, fresh, unleaded gasoline.

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

Gasoline with up to 10% ethanol (gasohol) is acceptable.

NOTICE: Do not use unapproved gasolines, such as E15 and E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. Use of unapproved fuels will cause damage to engine components, which will not be covered under warranty.

To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See Storage. All fuel is not the same. If starting or performance problems occur, change fuel providers or change brands. This engine is certified to operate on gasoline. The emissions control system for this engine is EM (Engine Modifications).

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON) gasoline is acceptable.

	Oil capacity (see the Specifications section)					For carbureted engines, high altitude adjustment is required to remain emissions

WARNING

POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a poisonous gas that could kill you in minutes. You CANNOT see it, smell it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas. If you start to feel sick, dizzy, or weak while using this product, shut it off and get to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

Operate this product ONLY outside far away from windows, doors and vents to reduce the risk of carbon monoxide gas from accumulating and potentially being drawn towards occupied spaces.

Install battery--operated carbon monoxide alarms or plug--in carbon monoxide alarms with battery back-up according to the manufacturer’s instructions. Smoke alarms cannot detect carbon monoxide gas.

DO NOT run this product inside homes, garages, basements, crawlspaces, sheds, or other partially-enclosed spaces even if using fans or opening doors and windows for ventilation. Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this product has shut off.

ALWAYS place this product downwind and point the engine exhaust away from occupied spaces.

NOTICE: This engine was shipped from Briggs & Stratton without oil. Before you start the engine, make sure you add oil according to the instructions in this manual. If you start the engine without oil, it will be damaged beyond repair and will not be covered under warranty.

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.

4.Move the throttle control (B) to the fast position. Operate the engine in the fast

position.

5.Move the choke control (C), or the combination choke/throttle lever, to the choke

position.

Note: Choke is usually unnecessary when restarting a warm engine.

6.Turn the electric start switch (D) to the on/start position (Figure 4).

NOTE: If the engine does not start after repeated attempts, contact your local dealer or go to BRIGGSandSTRATTON.COM or call 1-800-233-3723 (in USA).

NOTICE: To extend the life of the starter, use short starting cycles (five seconds maximum). Wait one minute between starting cycles.

7.As the engine warms up, move the choke control (C) to the run position.

How To Stop The Engine - Figure 4

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

Do not choke the carburetor to stop engine.

How To Service The Air Filter - Figure 8 9 10

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.

The air filter system uses either a flat, round, or oval air filter. Some models are also equipped with a pre-cleaner that can be washed and reused.

Flat Air Filter

1.Remove the cover (A, Figure 8).

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

2.Use pliers to squeeze tabs (B) on the clamps (C), then slide the clamps away from the fuel filter. Twist and pull the fuel lines (D) off of the fuel filter.

3.Check the fuel lines for cracks or leaks. Replace if necessary.

4.Replace the fuel filter with an original equipment replacement filter.

5.Secure the fuel lines with the clamps as shown.

How To Clean The Air Cooling System - Figure 12

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.

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 and the filter into the engine base (D).

6.Install the cover.

Round or Oval Air Filter

1.Remove the cover (A, Figure 9, 10).

2.To remove the filter (B), lift the end of the filter.

3.Remove the pre-cleaner (C), if equipped, from the filter.

NOTICE: Do not use water to clean the engine. Water could contaminate the fuel system. Use a brush or dry cloth to clean the engine.

This is an air cooled engine. Dirt or debris can restrict air flow and cause the engine to overheat, resulting in poor performance and reduced engine life.

Use a brush or dry cloth to remove debris from the finger guard/rotating screen (A). Keep linkage, springs and controls (B) clean. Keep the area around and behind the muffler free of any combustible debris (Figure 12). Make sure the oil cooler fins (C) are free of dirt and debris.
