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 (U.S.) / Distributor's Warranty
(CA.) does not cover parts damaged by misuse.
