• The combustion of propane by this engine produces carbon monoxide, a deadly, colorless, odorless,
poisonous gas. This engine is specically calibrated to operate at a very “lean” air/fuel ratio which minimiz-
es the production of carbon monoxide. Additionally, a catalyst muer is provided with this engine which
specically targets and eliminates any remaining carbon monoxide, making it safe to operate indoors.
• DO NOT OPERATE THIS ENGINE WITHOUT THE CATALYST MUFFLER.
• DO NOT TAMPER WITH REGULATOR OR OTHER SETTINGS WHICH WOULD ALTER AIR/FUEL RATIO.
• INSURE ANY INDOOR SITE OF USE HAS ADEQUATE VENTILATION WHICH MEETS INDUSTRY STANDARDS

CAUTION:
• Overlling propane cylinders is the number one cause of damage to the propane fuel system. This fuel
system is designed to run o vapor propane, not liquid propane. When the cylinder is overlled, liquid
propane will enter the fuel system and can damage lock-o and regulator, in addition to causing the engine
to run poorly or not at all. This voids the warranty on aected parts of the engine. To avoid problems, read
and understand fully, the section “FILLING PROPANE CYLINDERS”.
• OVERHEATING is a major cause of engine failure. Keep the engine clean and free of debris build up.
• Low oil levels and dirty oil account for most of the other failures. Follow the engine manual’s recom-
mended oil change schedule.

ABOUT PROPANE
• Propane is ammable and commonly used as a fuel.
• The molecular formula of propane is C3H8, and it is in the family of liqueed petroleum gases (LP gases).
The other LP gases include butane, propylene, butadiene, butylene, isobutylene and mixtures thereof.
• Propane is commonly available and has proven to be a dependable, safe, economical, and clean burning fuel.
It can be used as a household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been
used as a fuel since 1910.
• At atmospheric pressure, propane boils at -44 degrees Fahrenheit, meaning it typically exists as a vapor.
However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.
• Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct
odor similar to rotten eggs or skunk.
• Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.
PROPANE CYLINDERS (TANKS):
Propane cylinders are constructed according to ASME and Federal DOT #4ET20 pressure safety codes. All
valves and ttings are UL Listed. Propane gas is noncorrosive and will not rust the inside of a cylinder. It
is recommended to have propane cylinders inspected regularly during re-ll by an authorized National LP
Gas Association propane dealer. The fuel cylinder is supplied directly from the manufacturer and is void of
propane.
PROPANE CYLINDER CONFIGURATIONS:
Propane cylinders are constructed to function in specic congurations. The primary conguration options
are:
• Propane Withdrawal: Vapor or Liquid
• Cylinder Orientation: Horizontal or Vertical
IMPORTANT: Dierent cylinder congurations are not interchangeable.
All ONYX engines use Vapor cylinders, and the orientation can be either Horizontal or Vertical.
WARNING: NEVER use a cylinder not intended engine fuel applications. DO NOT substitute
cylinders that are used with a barbecue grill, etc.
CAUTION: Do not use propane cylinders that are liquid withdrawal cylinders, such as cylinders
for fork lift trucks or other liquid withdrawal applications.

CAUTION: Failure to use a proper cylinder or failure to install cylinder in proper orientation will
result in liquid propane withdrawal and cause damage the regulator.
FILLING PROPANE CYLINDERS
WARNING:
• Propane cylinders should only be lled by your propane provider or by individuals who have been proper-
ly trained and certied.
• Escaping propane can freeze skin and cause frostbite and damage eyesight. Always wear safety gloves
and safety glasses when lling propane cylinders.
• DO NOT overll cylinders.
• DO NOT tamper with cylinder gauges or safety relief valves.
• At time of ll, ensure tank is in operable condition and meets all certication requirements. Discontinue
use of any cylinder that is damaged or rusted or does not comply with certication requirements. Your
propane service company will assist with compliance.
STORING & TRANSPORTING PROPANE CYLINDERS:
The NFPA Technical Committee prohibits the storage of propane cylinders in buildings. Propane cylinders
should NOT be stored in buildings used by the public or frequented by anyone passing through or who is
working in the building. Full or empty, never leave cylinders in small enclosed areas. Cylinders must be
stored in a secure, tamper-proof storage enclosure that provides safety from accident or vandalism.
Propane cylinders should always be transported either secured to the machine using cylinder straps, or
secured in an upright position during transportation.

• Relief valve opens due to over pressurized cylinder creating hazardous situation.
• Moisture in the cylinder.
• Powered engine operates initially but shuts down when propane mixture becomes too lean.
The maximum ll volume of a propane cylinder is ALWAYS considered 80% of the total cylinder volume to
allow for expansion and to ensure proper vapor withdrawal from the cylinder.
For example, if your propane cylinder is referred to as a “20 lb cylinder”, this means that when the propane
cylinder is 80% full, the weight of the propane is 20 lb.
Cylinders should be lled in the vertical position.
When lling a propane cylinder, the xed liquid level gauge should be opened (unscrewed counterclock-
wise) so it can be used to determine when propane has reached 80% full. As propane is added during lling,
vapor will escape the small hole in this gauge. When the cylinder reaches 80% full, the escaping propane
will turn to liquid propane. When this happens, the lling should be immediately stopped and the gauge
should be closed (turned clockwise).

WHAT YOU NEED TO KNOW
The engine performance, reliability and life are inuenced by many factors, some external and some
strictly associated with the quality of the products used and with the scheduled maintenance.
The following information allow a better understanding and use of your engine.
ENVIRONMENTAL CONDITIONS:
The operation of a four-stroke endothermic engine is aected by:
a) Temperature:
– Working in low temperatures could lead to a dicult cold starting.
– Working in very high temperatures could lead to a dicult hot starting due to the evaporation
of the fuel either in the carburetor oat chamber or in the pump.
– In any case, the right kind of oil must be used, according to the operating temperatures.
b) Altitude:
– The higher the altitude (above sea level), the lower the max power developed by an endothermic
engine.
– When there is a considerable increase in altitude, the load on the machine should be reduced and
particularly heavy work avoided.
OIL:
Use always high quality oils, choosing their viscosity grade according to the operating temperature.
a) Use only detergent oil classied SJ,SL or higher are acceptable.
b) Choose the SAE viscosity grade of oil from this chart:
– from 5 to 35 °C = SAE 30
– from -25 to + 5 °C = 5W-20 or 5W-30 (Multi-viscosity)
– from -7 to + 35 °C = Synthetic oils 10W-30 or 15W-40 (Multi-viscosity)
c) The use of multi-viscosity oils in hot temperatures will result in higher than normal oil consumption;
therefore, check oil level more frequently.
d) Do not mix oils of dierent brands and features.
e) SAE 30 oil, if used below 5°C, could result in possible engine damage due to inadequate lubrication.
f) Oil should be at “MAX” mark do not overll. Overlling with oil may cause:
– Smoking;
– Spark plug or air lter fouling, which will cause hard starting.
AIR FILTER:
A good quality fuel is the major issue for the engine reliability of operation. The air lter must always
be in perfect working order, to prevent debris and dust from getting sucked into the engine, reducing
the eciency and life of the machine.
a) Always keep the ltering element free of debris and in perfect working order.
b) If necessary, replace the ltering element with an original spare part. Incompatible ltering ele-
ments can impair the eciency and life of the engine.
c) Never start the engine without mounting the ltering element properly.
WHAT YOU NEED TO KNOW
SPARK PLUG:
Not all the spark plugs for endothermic engines are the same!
a) Use only spark plugs of the recommended type, with the right heat range.
b) Check the length of the thread, because – if too long – it will damage the engine beyond repair.
c) Make sure that the electrodes are clean and their gap is correct.
STANDARDS OF USE
BEFORE EVERY USE:
Before every use, perform the following checking procedures in order to assurea regular operation.
CHECK THE OIL LEVEL:
See the specic chapter for the oil to be used.
a) Place the engine level.
b) Clean around oil ll.
c) Unscrew the cap, clean the end of the dipstick and insert it, as illustrated, without screwing it down.
d) Remove the cap with the dipstick and check the oil level that must be between “MIN” and “MAX”
marks.
e) If oil is required, add oil of the same kind up to the “MAX” mark, being careful not to spill any outside
the oil ll.
f) Fully tighten the llercap and wipe o any spilled oil.
CHECK THE AIR CLEANER:
The eciency of the air lter is fundamental for the engine to work properly. Do not start the engine if
the ltering element is missing or broken.
a) Clean around the lter cover.
b) Open the clips of the two sides of the air lter cover.
c) Check the condition of the ltering element. It must be intact, clean and in pefect working order; if
not, either carry out maintenance or replace it.
d) Put the cover back.
LONG STORAGE (OVER 30 DAYS):
In case the engine has to be stored for a long time (for example at the end of the season), a few precautions
are needed to help the future start-up.
a) To prevent the formation of deposits inside the tank, empty it of fuel by unscrewing the carburettor
oat chamber plug and collecting all the fuel in a suitable container. At the end of the operation remember
to screw the plug back on and fully tighten it.
b) Remove the spark plug and pour about 3 cl of clean engine oil into the spark plug hole, then, having
blocked the hole with a rag, run the starter motor briey to turn the engine for a few revs and distribute the
oil over the inner surface of the cylinder. Finally replace the spark plug without connecting the cable cap.

EMISSION CONTROL SYSTEM
To protect the environment the manufacturer has incorporated (1) crankcase emission and (2) exhaust
emission control systems (EM) in compliance with applicable regulations of the United States Environ-
mental Protection Agency and California Air Resources Board.
1. Crankcase Emission Control System. A sealed-type crankcase emission control system is used to elimi-
nate blow-by gases. The blow-by gases are led to the breather chamber through the crankcase where it is
led to the air cleaner. Oil is then separated from the gases while passing through the inside of the breather
chamber from the crankcase, and then returned back to the bottom of crankcase.
2. Exhaust Emission Control System. The exhaust emission control system applied to this engine consists
of a carburetor and an ignition system having optimum ignition timing characteristics. The carburetor has
been calibrated to provide lean air/propane mixture characteristics and optimum propane economy with a
suitable air cleaner and exhaust system.
TAMPERING WITH EMISSION CONTROL SYSTEM PROHIBITED
Federal law and California State law prohibits the following acts or the causing thereof: (1) the removal or
rendering inoperative by any person other than for purposes of maintenance, repair, or replacement, of
any device or element at design incorporated into any new engine for the purpose of emission control prior
to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the engine after such
device or element of design has been removed or rendered inoperative by any person.
Among acts presumed to constitute tampering involve the parts/systems listed below:
• Carburetor and internal parts
• Spark plugs
• Magneto or electronic ignition system
• Propane lter element
• Air cleaner elements
• Crankcase
• Cylinder heads
• Breather chamber and internal parts
• Intake pipe and tube

cause hard starting, and it leaves gum deposits that clog the fuel system. As a result, if the

from deterioration of the fuel in the fuel system and carburetor. The failure of the fuel system
or engine performance arising from improper storage are beyond the scope of the warranty.
