GENERAL INFORMATION
READING AND UNDERSTANDING THE MANUAL
Your engine should be used with due care and attention. Symbols have therefore been placed on the
engine to remind you of the main precautions to be taken. Their full meaning is explained later on. You
are also asked to carefully read the safety regulations in the applicable chapter of this handbook.
Some paragraphs in the manual containing information of particular importance for safety and operation
are highlighted at various levels of emphasis, and signify the following:
SAFETY SYMBOLS
NOTE: or IMPORTANT:
These give details or further information on what has already been said, and aim to prevent damage
either to the engine or other damages.
WARNING: Non-observance will result in the risk of injury to oneself or others.
DANGER: Non-observance will result in the risk of injury to oneself or others.
NOTE: All indications, “front”, “rear”, “right” and “left”, are to be taken as referring to the engine positioned
with the spark plug facing forwards with respect to the observer.
WARNING: Read and follow Operating Instructions before running engine.
WARNING: Propane is ammable. Allow engine to cool at least 2 minutes before refuelling.
WARNING: Engines emit carbon monoxide. DO NOT run in enclosed area.
GENERAL SAFETY STANDARDS
TRAINING:
1) Carefully read the instructions contained in this manual and the instructions of the machine on
which this engine is installed. Learn how to stop the engine quickly.
2) Never allow people unfamiliar with these instructions to use the engine.
3) Never use the engine while people, especially children, or pets are nearby.
4) Remember that the operator or user is responsible for accidents or hazards occurring to other
people or their property.

GENERAL SAFETY STANDARDS
PREPERATION:
1) Do not wear loose-tting clothing, dangling drawstrings, jewels or items that could become caught;
tie up long hair and keep at safe distance while starting the lawnmower.
2) Turn engine OFF and let it cool before removing gas cap.
3) WARNING: DANGER! Fuel is highly ammable:
– store the fuel in special containers;
– refuel only outdoors by using a funnel;
never smoke while refueling and/or handling fuel;
– add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel while the engine
is running or when the engine is hot;
– if you have split some fuel, do not attempt to start the engine but move the machine away from the
area of spillage and avoid creating any source of ignition until the fuel has evaporated and fuel vapours
have dissipated.
– always put the tank and fuel container caps
back on and tighten well.
4) Replace faulty silencers and the guard, if damaged.
OPERATION:
1) Do not operate the engine in a conned space where dangerous carbon monoxide fumes can collect.
2) Do not use starting uids or similar products.
3) Do not change the engine governor settings or overspeed the engine.
4) Do not tilt the machine onto its side to prevent fuel leaks from the fuel tank cap.
5) Do not touch the cylinder ns and/or the silencer guard until the engine has cooled down.
6) Stop the engine and disconnect the spark plug cable before checking, cleaning or servicing the machine
or the engine.
7) Do not crank the engine with spark plug removed.
8) Transport the machine with empty tank.
MAINTENANCE AND STORAGE:
1) A routine maintenance is essential for safety and for keeping a high performance level.
2) Do not store the machine with fuel in the tank in an area where the fuel vapours could reach an open
ame, a spark or a strong heat source.
3) Allow the engine to cool before storing in any enclosure.
4) To reduce the re hazard, keep the engine, the silencer and the fuel storage area free of grass, leaves, or
excessive grease.
5) If the fuel tank has to be drained, this should be done outdoors once the engine has cooled down.
6)On safety ground, never use the engine with either worn or damaged parts. Parts are to be replaced and
not repaired. Use genuine spare parts. Parts that are not of the same quality can damage the engine and
impair your safety.

LX700 19HP PROPANE ENGINE
ONYX LX700 engines operate on clean burning propane fuel signicantly reducing emissions while increasing
safety and reliability.
CLEANEST EMISSIONS IN CLASS
LEHR Propane Fuel Systems on the LX700 are certied 53% cleaner emissions than the closest engine in its class
according to the Environmental Protection Agency. Standard low tone catalytic muers reduce carbon monoxide
emissions well below OSHA permissible exposure limits. SAM Safe Air Monitor further increases safety by
alerting operators should carbon monoxide levels climb to unsafe levels and will automatically shut engines down
to prevent injury.
RELIABILITY
DESIGNED FOR PROPANE DURABILITY
LEHR Propane Fuel Systems use a patented variable venturi and fuel jet design which never comes out of
calibration and requires no eld adjustments. LEHR systems utilize a threestage pressure regulator that
vaporizes any liquid propane caused by overlled cylinders or use of liquid cylinders making the LX700 the
safest and most reliable engine in its class.
Heavy-duty piston rings, a cast iron cylinder liner, and hardened heads designed for propane fuel resist wear and
ensure precise timing for long engine life in commercial and industrial applications. Our heavy duty, low tone
catalytic muer is supported back to the engine block with two brackets and lasts the life of the engine.

WHAT YOU NEED TO KNOW
The engine performance, reliability and life are inuenced 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 aected by:
a) Temperature:
– Working in low temperatures could lead to a dicult cold starting.
– Working in very high temperatures could lead to a dicult 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 classied 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 dierent 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 overll. Overlling 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 eciency 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 eciency and life of the engine.
c) Never start the engine without mounting the ltering element properly.
