Note: Synthetic oil meeting ILSAC GF-2, API certification mark and API service symbol (shown at left) with SJ/CF ENERGY CONSERVING" or high- er, is an acceptable oil at all temperatures. Use of

synthetic oil does not alter required oil change intervals.CHECKING AND ADDING OIL

Fig. 3

•Check oil level before starting the engine.

•Check level daily, or after every eight (8) hours Ê.

•Keep oil level at FULL Ë.•Do not overfill.Oil filling procedure:1.First add 2 liters (67 ounces).2.Start and run engine at idle for 30 seconds. See Starting Instructions.3.Shut engine off and wait 30 seconds.4.Then add more oil slowly to bring level to Full mark on dipstick.Oil checking procedure:

1.Place engine level. Clean around oil fill and dipstick Ì.

2.Remove dipstick and wipe clean with cloth.

3.Then push dipstick back in and remove to check oil level. Oil should be at FULL line on dipstick Ë.

4.If oil is needed, add slowly.5.Fill to FULL line on dipstick − recheck.6.Replace dipstick firmly.

FUEL RECOMMENDATIONS

Use clean, fresh, regular unleaded gasoline with a minimum of 85 octane. Fresh fuel prevents gum from forming in the fuel system or on essential carburetor parts. Purchase fuel in quantity that can be used within 30 days.

•Do not use gasoline which contains Methanol.

•Do not mix oil with gasoline.

•For engine protection use Briggs & Stratton Gasoline Additive available from your Authorized Briggs & Stratton Dealer (P/N 5041 or single use pouch).

This engine is certified to operate on gasoline. Exhaust Emission Control System: EM (Engine Modifications).

CAUTION:

Some fuels, called oxygenated or reformulated gasoline, are gasoline blended with alcohols or ethers. Excessive amounts of these blendscan damage the fuel system or cause perfor- manceproblems. If any undesirable operating symptoms occur,use gasoline with a lower percentage of alcohol or ether.

ADDING FUEL

1.Remove cap. Fill tank to

WARNING approximately 1-1/2 inches below top of neck to allow for

fuel expansion. Be careful not to overfill.

2.Replace cap before starting.

STARTING/STOPPING

WARNINGOIL PRESSURE SWITCH

If engine is equipped with an oil pressure switch, the switch will either activate a warning light or stop the engine when the engine runs low on oil. (Read the operating instructions

supplied by the equipment manufacturer to determine which way your engine is equipped.)

See OIL PRESSURE in the MAINTENANCE SECTION for oil filling instructions.STARTING IN COLD WEATHER:

♦Use correct type of oil for expected starting temperature. See Oil.

♦Use fresh gasoline, which has higher volatility to improve starting.

♦Remove external equipment/engine loads. (See equipment operating instructions.)

♦Open fuel shut-off valve, if equipped, before starting engine.

♦Allow engine to warm up several seconds to several minutes, depending on outside temperature.

♦Gradually open choke.

♦For maximum performance and life, operate engine with choke in OPEN and throttle in FAST.

TO START ENGINE

1.Open fuel shut-off valve Ê (if equipped).2.Move choke control to CHOKE or START Ë.3.Move throttle (if equipped ) to FAST Ì.

4.Push rocker switch (if equipped ) to ON or RUN Í.

5.Insert key and turn to START Î.

CAUTION:

To prolong starter life, use short starting cycles (5 seconds maximum, then wait one minute). Follow equipment manufacturer’s recommendations for charging.

6.Allow engine to warm up. If choke equipped:

Slowly adjust toward RUN position. Wait until engine runs smoothly before each choke adjustment.

WARNING

The manufacturer of the equipment on which this engine is installed specifies top speed at which the engine will be operated. DO NOT EXCEED this speed.

TO STOP ENGINE

1.Move throttle to SLOW Ì (if equipped)2.Turn key OFF Î. Remove key and store out of reach of children.

3.Push rocker switch Í (if equipped) to OFF or STOP.

4.Close fuel shut-off valve Ê (if equipped).NATURAL / LIQUID PROPANEGAS POWERED ENGINESFUEL RECOMMENDATIONS

•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.

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.

ADDING FUEL

Read the operating instructions supplied by the equipment manufacturer for information on refueling natural or LP gas engine.

TO START ENGINE

Insert key and turn to START.

CAUTION:

To prolong starter life, use short starting cycles (5 seconds maximum, then wait one minute). Follow equipment manufacturer’s recommendations for charging.

TO STOP ENGINE

Turn key OFF. Remove key and store out of reach of children.

MAINTENANCE

Regular maintenance will improve the performance and extend the life of the engine. See any Authorized Briggs & Stratton Dealer for service. Use only genuine Briggs & Stratton parts. Other parts may not perform as well, may damage the engine, and may result in injury. In addition, use of other parts may void your warranty.

ENGINE AND ENGINE PARTS

We recommend that you see an authorized Briggs & Stratton Service Dealer for all maintenance and service of the engine and engine parts. Use only genuine Briggs & Stratton parts.

Perform the following at recommended intervals:Every 8 hours or dailyDCheck oil levelDCheck for oil leaks Every 50 hoursDCheck valve clearance *
