SAFETY PRECAUTIONS

• Make sure the engine is off before you begin any maintenance or
repairs. To prevent accidental startup, disconnect the spark plug
cap. This will eliminate several potential hazards:
– Carbon monoxide poisoning from engine exhaust.
Operate outside, away from open windows or doors.
– Burns from hot parts.
Let the engine and exhaust system cool before touching.
– Injury from moving parts.
Do not run the engine unless instructed to do so.
• Read the instructions before you begin, and make sure you have
the tools and skills required.
• To reduce the possibility of fire or explosion, be careful when
working around LPG or NATURAL GAS. Use only a
non-flammable solvent, not gasoline, to clean parts. Keep
cigarettes, sparks, and flames away from all fuel related parts.
Remember that an authorized Honda servicing dealer knows your
engine best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new Honda
Genuine parts or their equivalents for repair and replacement.

REFUELING

Recommended Fuel
LPG: Propane content of 95% or higher.
NATURAL GAS: Methane content of 90% or equivalent.
This engine is certified to operate on LPG or NATURAL GAS only.
Occasionally you may hear a light ''spark knock'' or ''pinging''
(metallic rapping noise) while operating under heavy loads. This is
no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under
normal load, see an authorized Honda servicing dealer.
Running the engine with persistent spark knock or pinging can
cause engine damage.
Running the engine with persistent spark knock or pinging is
considered misuse, and the Distributor's Limited Warranty does not
cover parts damaged by misuse.
