moving parts, etc.
•Used engine oils have been identified 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 first.
•DO NOT SMOKE while servicing batteries. Lead acid batteries give off a highly explosive hydrogen gas which can be ignited by flame, electrical arcing or by smoking.
•Verify battery polarity before connecting battery cables. Connect negative (-) cable last.
PROTECT AGAINST MOVING PARTS
•Do not wear loose clothing in the vicinity of moving parts, such as PTO shafts, flywheels, blowers, couplings, fans, belts, etc.
•Keep your hands away from moving parts
FUEL SYSTEMS
•DO NOT fill fuel tank while engine is running
•DO NOT smoke or use an open flame in the vicinity of the engine or fuel tank. Internal combustion engine fuels are highly flammable.
•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 flexible line. Do not use copper tubing as the flexible 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 identified 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 confined 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 fire hazard.

Installation
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 flammables or other hazardous 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.
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
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 flooding 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 fitting and then secure it with a hose clamp.
! WARNING Gaseous fuels are flammable and explosive and 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 flames, sparks, pilot lights, electrical switches, arc-producing equipment and all other sources of ignition well away. Keep a type ABC fire extinguisher handy.
Do not refill the fuel tank while the engine is running. Do not overfill 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 certified 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 components.
! CAUTION Do not use gasoline or gasoline additives containing methanol because methanol can be corrosive to fuel system components.

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.
EXPECTED AMBIENT |
SAE VISCOSITY |
TEMPERATURES |
GRADE |
32°F (0° C) and higher |
30 |
0°F to 80°F |
10W-30 |
(-18°C to 27°C) |
10W-40 |
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 first 20 hours of operation the initial oil and oil filter should be replaced.
Thereafter, change the oil every 100 hours of operation and change the oil filter every 200 hours.
Apply a thin coat of oil to the oil filter gasket surface and install by tightening the oil filter 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 filling the crankcase, keep the engine level and fill up to the upper mark of the oil gauge. Check the oil with the oil gauge pushed all the way in its seat.
! WARNING Crankcase pressure can blow hot engine oil out the fill tube causing severe burns. Always stop the engine before removing the oil fill cap or the
oil gauge.
15
Check the oil level daily, before starting. Keep the oil level between the upper and lower level on the gauge.
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 flat strap 25.0mm (0.25”) wide.
