WARNING

Starting engine creates sparking.

Sparking can ignite nearby flammable gases.

Explosion and fire could result.

If there is natural or LP gas leakage in area, do not start engine.

Do not use pressurized starting fluids because vapors are flammable.

WARNING

Engines give off carbon monoxide, an odorless, colorless, poison gas. Breathing carbon monoxide can cause nausea, fainting or death.

Start and run engine outdoors.

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

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.

How To Start The Engine

 

 

 

 

 

 

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.

 

* Below 40°F (4°C) the use of SAE 30 will result in hard starting.

 

 

 

 

 

 

 

 

 

 

 

 

** Above 80°F (27°C) the use of 10W-30 may cause increased oil consumption. Check

 

 

 

 

 

oil level more frequently.

 

 

 

 

WARNING

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Fuel and its vapors are extremely flammable and explosive.

How To Check/Add Oil - Figure 2

 

 

 

 

 

 

 

Before adding or checking the oil

 

 

 

When Starting Engine

 

 

Place engine level.

 

 

 

 

 

 

 

 

Ensure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in

place and secured.

 

1.

Remove the dipstick (A) and wipe with a clean cloth (Figure 2).

 

 

 

Do not crank engine with spark plug removed.

2.

Insert and tighten the dipstick.

 

 

 

 

If engine floods, set choke (if equipped) to OPEN/RUN position, move throttle

3. Remove the dipstick and check the oil level. It should be at the top of the full indicator

 

(if equipped) to FAST position and crank until engine starts.

 

 

 

 

 

(B) on the dipstick.

 

 

 

 

 

 

 

4.If low, add oil slowly into the engine oil fill (C). Do not overfill. After adding oil, wait one minute and then recheck the oil level.

5. Replace and tighten the dipstick.

 

WARNING

 

 

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

 

 

Fuel Recommendations

 

Breathing carbon monoxide can cause nausea, fainting or death.

 

 

Fuel must meet these requirements:

 

 

Start and run engine outdoors.

Clean, fresh, unleaded gasoline.

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

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

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

CAUTION: 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 damage the engine components and void the engine warranty.

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.

BRIGGSandSTRATTON.COM

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.

Primer System: This features a red primer to be used for starting in cool temperatures. It does not have a manual choke.

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

Note: Equipment may have remote controls. See the equipment manual for location and operation of remote controls.

Maintenance

NOTICE: If the engine is tipped during maintenance, 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.

WARNING: When performing maintenance that requires the unit to be

tipped, the fuel tank must be empty or fuel can leak out and result in a fire or explosion.

We recommend that you see any Briggs & Stratton Authorized Dealer for all maintenance and service of the engine and engine parts.

NOTICE: All the components used to build this engine must remain in place for proper operation.

Inspect Muffler And Spark Arrester - Figure 1

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 (H, Figure 1) for cracks, corrosion, or other damage. Remove the spark arrester, 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.

1.Remove the dipstick (G) and wipe with a clean cloth (Figure 11).

2.Pour the oil slowly into the engine oil fill (H). Do not overfill. After adding oil, wait one minute and then check the oil level.

3.Install and tighten the dipstick.

4.Remove the dipstick and check the oil level. It should be at the top of the full indicator (J) on the dipstick.

5.Install and tighten the dipstick.

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.

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.
