Maintenance, replacement or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, to obtain no charge repairs under the terms and provisions of the Briggs & Stratton warranty statement, any service or emission control part repair or replacement must be performed by a factory authorized dealer.

In the Interest of Safety

This safety alert symbol indicates that this message involves personal safety. Words danger, warning and caution indicate degree of hazard. Death, personal injury and/or property damage may occur unless instructions are followed carefully.

You are not ready to operate this engine if you have not read and understood the following safety items. Read this entire owner's manual and the operating instructions of the equipment this engine powers.

The Briggs & Stratton engine you bought with your equipment is made of the finest material in a state-of-the-art manufacturing facility. Please understand that Briggs & Stratton sells engines to original equipment manufacturers. It also sells to others in the distribution chain who may sell to the ultimate consumer, an equipment manufacturer, another distributor or a dealer. As a result, Briggs & Stratton does not necessarily know the application on which the engine will be placed. For that reason, you should carefully read and understand the operating instructions of the equipment on which your engine is placed before you operate it.

You should also understand that there are equipment applications for which Briggs & Stratton does not approve the use of its engines. Briggs & Stratton engines are not to be used on vehicles with less than 4 wheels. They include motor bikes, aircraft products and All Terrain Vehicles. Moreover, Briggs & Stratton does not approve of its engines being used in competitive events. F0R THAT REASON, BRIGGS & STRATTON ENGINES ARE NOT AUTHORIZED FOR ANY OF THESE APPLICATIONS. Failure to follow this warning could result in death, serious injury (including paralysis) or property damage.

Oil & Fuel Recommendations

Oil

This engine is shipped from Briggs & Stratton without oil. Before starting engine, check oil level as shown below.

Change and add oil according to chart below. Do not over-fill.

Use a high quality detergent oil classified ªFor Service SF, SG, SH,º such as Briggs & Stratton ªwarranty certifiedº SAE 30 oil, Part No. 100005. Use no special additives with recommended oils. Do not mix oil with gasoline.

SAE Viscosity Grades

						*
°F	-20	0	20	32	40		60	80	100
°C	-30	-20	-10	0		10	20	30	40

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

*Air cooled engines run hotter than automotive engines. The use of

multi-viscosity oil such as (10W-30, etc.) in ambient temperatures above 40°F (4°C) will result in higher than normal oil consumption. If multi-viscosity oil is used, check the oil level more frequently to prevent any possible engine damage due to lack of lubrication.

**Use of SAE 30 oil below 40° F (4° C) will result in hard starting and possible engine damage due to inadequate lubrication.

Fuel

Use clean, fresh, regular unleaded gasoline with a minimum of 77 octane. Do not mix oil with gasoline. Fresh fuel prevents gum from forming in fuel system or on essential carburetor parts. Purchase fuel in quantity that can be used within 30 days. In countries other than the U.S.A., leaded gasoline may be used if commercially available and unleaded is unavailable.

We recommend the use of Briggs & Stratton Gasoline Additive. (See your Authorized Briggs & Stratton Service Dealer for Part No. 5041 or the single-use pouch.) See storage instructions, on page 9.

Note: Some fuels, called oxygenated or reformulated gasolines, are gasolines blended with alcohols or ethers. Excessive amounts of these blends can damage the fuel system or cause performance problems. Do not use gasoline which contains Methanol. If any undesirable operating symptoms occur, use gasoline with a lower percentage of alcohol or ether.

Do not over-fill fuel tank.

Allow space for fuel expansion.

Check oil level before starting engine.

Add oil as shown below.

Oil capacity of Model Series 190000 is about 1-1/8 quarts (36 ounces or 1.1 liters).

Oil capacity of Model Series 280000 is about 1-1/2 quarts (48 ounces or 1.4 liters).

After filling with or changing oil, start and run engine at idle for 30 seconds. Shut engine off. Wait 30 seconds and check oil level. Add oil, if required, to bring level to Full mark on dipstick.

Starting & Stopping

Choke operation/engine warm-up

This engine is a low emissions engine which operates differently from previously built engines. It is designed for maximum performance and life if operated with the choke fully open (in RUN) and throttle fully open (in FAST). To open the choke fully requires an engine warm-up period of several seconds to several minutes, depending on the temperature.

After starting engine, first open the choke (toward RUN) until the engine just begins to run smoothly. Then open the choke in small steps, allowing the engine to accept small changes in speed and load, until the choke is fully open (in RUN).

During engine warm-up, the equipment can be operated.

To obtain best starting results

Store and fuel lawn mower in level position.

Start lawn mower on hard surface or over previously cut grass.

Do not use a pressurized starting fluid. Starting fluid is flammable. Severe engine damage or fire may occur.

Periodically remove grass build-up under mower deck. Remove spark plug wire before removing grass. When tipping lawn mower to remove grass, keep spark plug side of engine up.

A warm engine requires less choking than a cold engine.

Starting in cold weather

Use the correct oil for the starting temperature expected.

De-clutch all possible external loads.

Set speed control at part throttle position.

A warm battery has more starting capacity than a cold battery.

Do not use gasoline left over from summer. Use fresh winter grade gasoline which has higher volatility to improve starting.

Before starting engine

Move choke control to CHOKE or START position.

Note: Choke must fully close. If engine does not start, see control adjustments on page 5.

Start engine

Always keep hands and feet clear of mower blade or other rotating machinery.

Rewind starter

Grasp rope handle as illustrated and pull slowly until resistance is felt. Then pull cord rapidly to overcome compression,

prevent kickback and start engine.

Repeat if necessary with choke off and throttle control in FAST position. Operate engine in FAST position.

Rewind starter

Electric starter, if equipped

Turn key to START or press button. Repeat if necessary with throttle control in FAST position. Operate engine in FAST position.

Note: If equipment manufacturer has supplied battery, charge it before trying to start engine, as equipment manufacturer recommends. Use short starting cycles (15 secs. per min.) to prolong starter life. Extended cranking can damage starter motor.

PRESS

Typical electric starter

Stop engine

Do not move choke control to CHOKE position to stop engine. Backfire or engine damage may occur.

Move throttle control to SLOW position, then to STOP or turn key to OFF, depending on how equipped.

Always remove key from switch, if equipped, when equipment is not in use or left unattended.

Typical stop controls

When engine is transported, close fuel shut-off valve (if engine is equipped) to prevent fuel leakage.
