Your lawnmower is shipped without oil in the engine.

For type and grade of oil to use. see "ENGINE" in the Maintenance section of this manual.

• i. CAUTION: DO NOT overfill engine with oil. or it will smoke heavily from the muffler on startup.

Be sure lawnmower is level.

Remove oil dipstick from oil fill spout.

You receive a container of oil with the unit.

Slowly pour the entire container down the oil fill spout into the engine.

NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the manufacturers 100% quality testing.

When changing oil you may need 20 oz.

Insert and tighten dipstick.


• Check oil level before each use.

Add oil if needed.

Fill to full line on dipstick.

• Change the oil after every 25 hours of operation or each season.

You may need to change the oil more often under dusty. dirty conditions.

See "TO CHANGE ENGINE OIL" in the Mainte nance section of this manual.

ADD GASOLINE Fill fuel tank to bottom of tank filler neck.

Do not overfill.

Use fresh. clean. regular unleaded gasoline with a minimum of 87 octane.

Do not mix oil with gasoline.

Purchase fuel in quantities that can be used within 30 days to assure fuel fresh ness. CAUTION" Wipe off any spilled oil or fuel.

Do not store. spill or use gasoline near an open flame. CAUTION: Alcohol blended fuels (called gasohol or using ethanol or metha nol) can attract moisture which leads to separation and formation of acids during storage.

To stop engine. release operator pres ence control bar.


NOTE: Due to protective coatings on the engine. a small amount of smoke may be present during the initial use of the product and should be considered normal.

NOTE: Your engine is equipped with an automatic choke system.

No priming or choking is required before starting. To start engine. hold operator presence control bar down to the handle and pull starter handle quickly.

Do not allow starter rope to snap back.

MOWING TiPS _. CAUTION: Do not use de-thatcher blade attachments on your mower. Such attachments are hazardous. will damage your mower and could void your warranty. Under certain conditions. such as very tall grass. it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clippings.

It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time. For extremely heavy cutting. reduce the width of cut by overlapping previously cut path and mow slowly. For better grass bagging and most cut ting conditions. the engine speed should be set in the FAST position. Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass. To prevent this. regularly hose catcher off with water and let dry before using. Keep top of engine around starter clear and clean of grass clippings and chaff.

This will help engine air flow and extend engine life.


IMPORTANT: For best performance. keep mower housing free of built-up grass and trash. See "CLEANING" in the Maintenance section of this manual.

The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed.

Also. the mulched grass will biodegrade quickly to provide nutrients for the lawn.

Always mulch with your highest engine (blade) speed as this will provide the best recut ting action of the blades. Avoid cutting your lawn when it is wet.

Wet grass tends to form clumps and interferes with the mulching action.

The best time to mow your lawn is the early afternoon.

At this time the grass has dried. yet the newly cut area will not be exposed to direct sunlight. For best results. adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass blades.

If the lawn is overgrown it will be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of mulched grass.

For extremely heavy grass. reduce your width of cut by overlapping previously cut path and mow slowly.

MAX 1/3

Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings.

When doing a sec ond cut. mow across (perpendicular) to the first cut path. Change your cutting pattern from week to week.

Mow north to south one week then change to east to west the next week.

This will help prevent matting and graining of the lawn.

IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor. fuel filter. fuel hose. or tank during storage.

Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage.

Acidic gas can damage the fuel system of an engine while in storage. Empty the fuel tank by starting the en gine and letting it run until the fuel lines and carburetor are empty. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage.

Add stabilizer to gasoline in fuel tank or stor age container.

Always follow the mix ratio found on stabilizer container.

Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the car buretor.

Do not empty the gas tank and carburetor if using fuel stabilizer.


Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Maintenance section of this manual).


Remove spark plug.

Pour one ounce (29 ml) of oil through spark plug hole into cylinder.

Pull starter handle slowly a few times to distribute oil.

Replace with new spark plug.


Do not store gasoline from one season to another. Replace your gasoline can if your can starts to rust.

Rust and/or dirt in your gasoline will cause problems. If possible. store your unit indoors and cover it to protect it from dust and dirt.

• Cover your unit with a suitable protec tive cover that does not retain moisture.

Do not use plastic.

Plastic cannot breathe. which allows condensation to form and will cause your unit to rust.

IMPORTANT: Never cover mower while engine and exhaust areas are still warm. &CAUTION: Never store the lawn

Engine Power Rating information

The gross power rating for individual gas engine models is labeled in accordance with SAE (So ciety of Automo-tive Engineers) code J11940 (Small Engine Power & Torque Rating Procedure). and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-5).

Actual gross engine power will be lower and is affected by. among other things. ambi ent operating conditions and engine-to-engine variability.

Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment. the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net horsepower).

This difference is due to a variety of factors including. but not limited to. accessories (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 Series engine.
