Safety Precautions
Before operating the engine, read this manual and become
familiar with it and the equipment. Safe and efficient operation
can be achieved only if the equipment is properly operated and
maintained.
The following symbols, found throughout this manual, alert you to
potentially dangerous conditions to the operator, service personnel, or
the equipment.
This symbol warns of immediate hazards which will
result in severe personal injury or death.
This symbol refers to a hazard or unsafe practice
which can result in severe personal injury or death.
This symbol refers to a hazard or unsafe practice
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
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 fire 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 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 imme-
diately, 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.
