toxic gas that can kill you in minutes. Do not run in an enclosed area.

Hot surface can burn you. Stay away if engine has been running.

SAFETY PRECAUTIONS

The safety alert symbol ( ) is used with a signal word (DANGER, CAUTION, WARNING), a pictorial and/or a safety message to alert you to hazards.

DANGER indicates a hazard which, if not avoided, will result in death or serious injury. WARNING indicates a hazard which, if not avoided, could result in death or serious injury. CAUTION indicates a hazard which, if not avoided, might result in minor or moderate injury.

NOTE indicates a situation that could result in engine damage. Follow safety messages to avoid or reduce the risk of injury or death.

The manufacturer cannot possibly anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and the tags and decals afﬁ xed to the unit are, therefore, not all-inclusive. If you use a procedure, work method or operating technique that the manufacturer does not speciﬁ cally recommend you must satisfy yourself that it is safe for you and others. You must also make sure that the procedure, work method or operating technique that you choose does not render the engine system unsafe.

These safety warnings cannot eliminate the hazards that they indicate. Common sense and strict compliance with the special instructions while performing the action or service are essential to preventing accidents.

Study these RULES FOR SAFE OPERATION carefully before operating or servicing this equipment. Become familiar with the OWNER’S MANUAL and with the engine. The engine can operate safely, efﬁ ciently and reliably only if it is properly operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions.

SAFETY PRECAUTIONS

BEFORE OPERATING

• Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE. Do not permit smoking, open ﬂ ames, sparks or heat in the area while handling gasoline. Avoid spilling gasoline on a hot engine. Comply with all of the laws regulating storage and handling of gasoline.

•Store gasoline and other fuels only in containers designed and approved for the storage of such materials.

• Pressure can build up in the fuel tank. Loosen the fuel cap slowly to relieve any pressure in the tank.

• Add gasoline and other fuels in a clean, well-ventilated area. Wipe up any spilled gasoline immediately. If gasoline has been spilled, let it dry completely before starting the engine.

• Do not overﬁ ll the fuel tank. Always allow room for fuel expansion. If the tank is overﬁ lled, the fuel can overﬂ ow onto a hot engine and cause a FIRE or an EXPLOSION.

• Thoroughly inspect the engine for loose or damaged parts before each use. Do not use the engine until adjustments or repairs are made.

• Check the oil level in the engine before each use.

• Inspect the engine periodically. Repair or replace all damaged or defective parts immediately.

• Inspect fuel system frequently for leaks or damage. Repair or replace any damaged or leaking component immediately. Never attempt to change, alter or modify the engine fuel system in any way that might affect safety or compliance with applicable codes and standards.

• This engine requires an adequate ﬂ ow of cooling air for its continued proper operation. Never operate the equipment inside any room or enclosure where the free ﬂ ow of cooling air into and out of the equipment might be obstructed. Without sufﬁ cient cooling air ﬂ ow, the engine quickly overheats, damaging the engine or nearby property.

• Do not smoke around the engine. Wipe up any fuel or oil spills immediately. Never leave oily or fuel soaked rags around the engine. Keep the area around the engine clean and free of debris.

• Keep hands, feet, clothing, etc., away from moving parts of this engine.

• Never operate the engine (a) in the rain; (b) in any en- closed compartment; (c) if the engine speed changes; (d) if the engine sparks; (e) if ﬂ ame or smoke is observed while the engine is running.

• Never work on this engine or handle any electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRIC SHOCK will result.

• Allow mufﬂ er, engine cylinder and ﬁ ns to cool before touching.

• Remove accumulated combustibles from mufﬂ er area and cylinder area.

• Install and maintain in working order a spark arrester before using equipment on forest covered, grass covered, brush covered unimproved land.

SERVICE INFORMATION

WHILE OPERATING

• This engine was designed and manufactured for speciﬁ c applications. Do not attempt to modify the equipment or use it for any application for which it was not designed.

• Engine exhaust gases contain DEADLY carbon monoxide gas. This dangerous gas, if breathed in sufﬁ cient concentrations, can cause unconsciousness or even death. Operate this equipment only in the open air where adequate ventilation is available.

• Do not insert any object through the cooling slots of the engine. This could damage the equipment or injure personnel.

• Do not operate the engine faster than the speed necessary to operate the equipment. Do not run the engine at high speed when not operating the equipment.

Service on this engine within and after the warranty period can be performed by any authorized Subaru service dealer.

GENERAL INFORMATION

OIL AND FUEL INFORMATION

NOTE: Be sure to read these instructions carefully before attempting to start or operate this equipment. Using old or improper oil or fuel can cause engine damage.

CAUTION

▲

Any attempt to crank or start the engine before

▲

it has been properly serviced with the recommended oil may result in engine damage.

This engine is shipped from the manufacturer

without oil. Check oil level before starting engine. The engine will be damaged beyond repair and will not be covered under warranty if started without oil.

RECOMMENDED OIL TYPE

Use only high quality detergent oil rated with an API service classiﬁ cation SJ or higher. DO NOT use oil designated “For Diesel Engines Only”. The use of a multi-weight oil (10W-30) may result in higher than normal oil consumption. Therefore, checking the oil level more frequently may be required. The recommended oil weights include the following:

• During summer months: SAE30. An acceptable substitute is SAE 10W-30. After ﬁ rst oil change, synthetic oil is acceptable.

• During winter months: SAE 5W-30, or after the ﬁ rst oil change, synthetic 5W-30 can be used. DO NOT USE SAE

10W-40.

Temperature Range of Expected Use

Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before each use and change the oil regularly (see Figure 1). Failure to use the correct oil, or using dirty oil, can cause premature engine wear and failure.

CHANGE OIL

Use no special additives. Make sure that the unit is level when ﬁ lling with oil. DO NOT OVERFILL.

IMPORTANT: DO NOT OVERFILL. Check and maintain oil level regularly. Change oil and ﬁ lter after ﬁ rst eight (8) hours of operation. Thereafter, change oil and ﬁ lter every 100 hours of operation. Change oil more often if engine is operated in dirty or dusty conditions or if engine is operated under heavy loads or in high ambient air temperatures.
