Safety Codes
• All local, state and federal codes should be consulted
and complied with.
• This engine is not designed or intended for use in
aircraft. Any such use is at the owner’s sole risk.

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 ex¬
hausts. moving parts, etc.
Protect Against Moving Parts
• Do not wear loose clothing in the vicinity of moving
parts, such as PTO shafts, flywheels, blowers, coup¬
lings, fans, belts, etc.
• Keep your hands away from moving parts.
Batteries
• Before starting work on the engine, disconnect batter¬
ies to prevent inadvertent starting of the engine.
• DO NOT SMOKE white 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.
Fuel System
• DO NOT fill fuel tanks 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 lines must be of steel piping, adequately secured,
and free from leaks. Piping at the engine should be
approved flexible line. Do not use copper piping for
flexible lines as copper will work harden and become
brittle enough to break.
• Be sure all fuel supplies have a positive shutoff valve.
Exhaust System
• Exhaust products of any internal combustion engine
are toxic and'can cause injury, or death if inhaled. All
engine applications, especially those within a confined
area, should be equipped with an exhaust system to
discharge gases to the outside atmosphere.
• Do not use exhaust gases to heat a compartment.
• Make sure that your exhaust system is free of leaks.
Ensure that exhaust manifolds are secure and are not
warped by botts unevenly torqued.
Exhaust Gas is Deadly!
Exhaust gases contain carbon monoxide, a poisonous gas
that might cause unconsciousness and death. It is an
odorless and colorless gas formed during combustion of
hydrocarbon fuels. Symptoms of carbon monoxide poi¬
soning are:
• Dizziness • Vomiting
• Headache • Muscular Twitching
• Weakness and Sleepiness • Throbbing in Temples
If you experience any of these symptoms, get out into fresh
air immediately, shut down the unit and do not use 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.
Cooling System
• Coolants under pressure have a higher boiling point
than water. DO NOT open a radiator pressure cap when
coolant temperature is above 212° F (100°C) or while
engine is running.
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.
