which can result in personal injury or product or property damage.

Fuels, electrical equipment, batteries, exhaust gases and moving parts present potential hazards that can result in severe personal injury. Take care in following these recommended procedures. All local, state and federal codes should be consulted and complied with.

This engine is not designed or intended for use in

! WARNING

any type of aircraft. Use of this engine in aircraft can result in engine failure and cause severe personal injury or death.

GENERAL

• Provide appropriate ﬁ re extinguishers and install them in convenient locations. Use an extinguisher rated ABC by NFPA.

• Make sure that all fasteners on the engine are secure and accurately torqued. Keep guards in position over fans, driving belts, etc.

• If it is necessary to make adjustments while the engine is running, use extreme caution when close to hot exhausts,

moving parts, etc.

• Used engine oils have been identiﬁ ed by some state and

federal agencies as causing cancer or reproductive toxicity. When checking or changing engine oil, take care not to ingest, breathe the fumes, or contact used oil.

• Do not work on this equipment when mentally or physically

fatigued, or after consuming any alcohol or drug that makes the operation of equipment unsafe.

BATTERIES

• Before starting work on the engine, disconnect batteries to prevent

inadvertent starting of the engine. Disconnect negative (-) cable ﬁ rst.

• DO NOT SMOKE while servicing batteries. Lead acid batteries give

off a highly explosive hydrogen gas which can be ignited by ﬂ ame, electrical arcing or by smoking.

• Verify battery polarity before connecting battery cables. Connect

negative (-) cable last.

PROTECT AGAINST MOVING P ARTS

• Do not wear loose clothing in the vicinity of moving parts, such as

PTO shafts, ﬂ ywheels, blowers, couplings, fans, belts, etc.

• Keep your hands away from moving parts

FUEL SYSTEMS

• DO NOT ﬁ ll fuel tank while engine is running

• DO NOT smoke or use an open ﬂ ame in the vicinity of the engine or

fuel tank. Internal combustion engine fuels are highly ﬂ ammable.

• Fuel line must be made of steel tubing which adequately secured,

and free from leaks. Tubing which connects to the carburetor should be factory approved ﬂ exible line. Do not use copper tubing as the ﬂ exible lines as copper will harden and become brittle enough to break.

• Be sure all fuel supplies have a positive shutoff valve.

• Benzene and lead, found in some gasoline, have been identiﬁ ed by

some state and federal agencies as causing cancer or reproductive toxicity. When checking, draining, or adding gasoline take care not to ingest, breathe fumes, or contact the gasoline.

EXHAUST SYSTEM

• Exhaust products of any internal combustion engine are toxic and can cause injury, or death it inhaled. When operating the engine in a conﬁ ned area, make sure the ventilation system is operating properly.

• DO NOT use exhaust gases to heat a compartment.

• Make sure that your exhaust system is free of leaks. Make sure that exhaust manifolds are secure and are not warped by bolts unevenly torqued.

EXHAUST GAS IS DEADLY!

Exhaust gases contain carbon monoxide, a poisonous gas that can cause unconsciousness and death. It is an odorless and colorless gas formed during combustion of hydrocarbon fuels. Symptoms of carbon monoxide poisoning are:

• Dizziness

• Vomiting

• Headache

• Muscular Twitching

• Throbbing in Temples

• Weakness and Sleepiness If you experience any of these symptoms, get out into fresh air immediately, shut down the unit and do not use it until it has been inspected. The best protection against carbon monoxide inhalation is proper installation and regular, frequent inspections of the complete exhaust system. If you notice a change in the sound or appearance of exhaust system, shut the unit down immediately and have it inspected and repaired at once by a competent mechanic.

KEEP THE UNIT AND SURROUNDING AREA CLEAN

• Make sure that oily rags are not left on or near the engine.

• Remove all unnecessary grease and oil from the unit. Accumulated grease and oil can cause overheating and subsequent engine damage and present a potential ﬁ re hazard.

Description

FEATURES

• Overhead valve arrangement enables high power, and low fuel and

oil consumption

• V-Twin, four stroke design

• Air-cooled and gasoline fueled

• The light weight and compact design makes it easy to install and

utilize for many applications.

• A steel crankshaft and high-load bearing offer durability

• Pressure lubrication system and large capacity air cleaner enhance

reliability of the engine.

• The combustion chamber shape, along with a tuned exhaust valve

system, enhance the low exhaust emission and provides high torque at low speed.

Standard features include a fuel cut-of valve, a 12V-15 amp alternator and a pulse-type fuel pump.

The ﬂ ywheel-type governor gear provides constant operation at the selected speed against load variations.

The carburetor is a down draft, ﬂ oat controlled fuel system with a ﬁ xed main jet. A fuel cut-off valve is provided to secure engine shut-down when the switch is turned off. Carburetors are calibrated for sure starting, good acceleration, low fuel consumption and adequate power output. A throttle solenoid (optional) automatically senses when the engine needs to run at full power and when it requires idle speed. The solenoid operates using a 15 second delay before dropping to idle.

LOCATING

Locate the engine at least 1 meter (3.0 ft) away from buildings or other structures. Provide proper exhaust routing. Refer to EXHAUST SYSTEM below. Do not use the engine near ﬂ ammables or other hazard- ous materials such as trash, rags, lubricants, or explosives. When determining the mounting location, make sure of the following:

• Gas and oil can easily be checked and supplied

• Oil can be changed.

• The air cleaner can be serviced

• Spark plugs can be checked.

Carefully examine the engines position, the method of connecting it to a machine, and the foundation and support structure. Locate the engine in a safe area on a stable level surface free of small rock, loose gravel, etc.

! CAUTION

Operating the engine on an incline may cause

seizure due to improper lubrication; even at maximum oil level.

carburetor. If the tank is mounted above the carburetor, a fuel shut-off valve must be connected between the fuel tank and the fuel pump.

Note: To prevent fuel from ﬂ ooding the carburetor, the fuel valve must be closed when the engine is not running.

Properly install fuel lines to the carburetor by completely inserting the hose onto the ﬁ tting and then secure it with a hose clamp.

Gaseous fuels are ﬂ ammable and explosive and

! WARNING

can cause severe personal injury or death. Do not smoke if you smell gas or are near fuel tanks or fuel-buring equipment or are in an area sharing ventilation with such equipment. Keep ﬂ ames, sparks, pilot lights, electrical switches, arc-producing equipment and all other sources of ignition well away. Keep a type ABC ﬁ re extinguisher handy.

EXHAUST SYSTEM

EXHAUST GAS IS DEADLY! Engine-powered equipment must never be operated inside buildings or other enclosed spaces. If a long exhaust pipe is used, the internal resistance results in loss of engine power. The exhaust pipe ID must increase in proportion to exhaust pipe length. For example, if the exhaust pipe is: less than 3.0 m (9.8 ft.) long - pipe ID = 30mm (1-3/16in)

less than 5.0 m (16.4 ft)long - pipe ID = 33mm (1.3in) It is the responsibility of the equipment operator(s) to check for

exhaust leaks on a daily basis and to have all leaks repaired before continuing to operate the equipment.

FUEL Fuel Tank

The fuel tank system must be provided by the OEM. A fuel shut-off valve must connected between the fuel line and the fuel pump.

The fuel tank may be mounted up to 0.66 meters (2.0ft) below the

Do not reﬁ ll the fuel tank while the engine is running. Do not overﬁ ll the tank. Wipe away any spilled fuel and wait until it has dried before starting the engine.

Fuel recommendations

Use clean, fresh unleaded gasoline having a minimum octane rating (Anti-Knock Index) of 87. This engine is certiﬁ ed to operate on unleaded gasoline. During some periods of the year only mandated “oxygenated” gasolines may be available. These are acceptable for use, but not preferable. Do not use gasoline or gasoline additives (de-icers) containing methanol because methanol can be corrosive to fuel system compo-

nents.

! CAUTION

Do not use gasoline or gasoline additives containing methanol because methanol can be corrosive to fuel system components.

Installation

ENGINE OIL Recommendations

Use premium quality motor oil, Class SJ or SL. Look for the SAE (Society of Automotive Engineers) or API viscosity grade. Referring to the table below, choose the viscosity grade appropriate for the ambient temperatures expected during the period of time until the next scheduled oil change.

Check the oil level daily, before starting. Keep the oil level between the upper and lower level on the gauge.

EXPECTED AMBIENT TEMPERATURES

SAE VISCOSITY

GRADE 32°F (0° C) and higher 30 0°F to 80°F

(-18°C to 27°C)

Single-grade SAE 30 oil is preferable when temperatures are 50° and 90°F (10° - 32°C). If multi-grade oil is used, oil consumption tends to increase if the ambient temperature is high.

Filling and Change Interval

After the ﬁ rst 20 hours of operation the initial oil and oil ﬁ lter should be replaced. Thereafter, change the oil every 100 hours of operation and change the oil ﬁ lter every 200 hours. Apply a thin coat of oil to the oil ﬁ lter gasket surface and install by tightening the oil ﬁ lter about 3/4 turn after the seal has reached the crankcase surface. The oil capacity of the crankcase is 1.55L (53 ﬂ .oz.). When ﬁ lling the crankcase, keep the engine level and ﬁ ll up to the up- per mark of the oil gauge. Check the oil with the oil gauge pushed all the way in its seat.

STARTING BATTERIES

An engine equipped with an electric starter requires a properly sized battery along with appropriately sized interconnecting cables to insure proper starting. Neither cranking performance or starter service life will be satisfactory if an undersized battery is used. Use a battery rated 12V-30 amp or larger. The customer must supply battery cables. Use the table below to select the proper cable for the positive side connection. Connect a ground strap to the negative terminal. Use a ﬂ at strap
