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.
