• Use clean, dry fuel, free of moisture or any particulate material. Fuels used
outside the recommended values can cause performance problems.
• On engines that operate on LPG, commercial grade HD5 LPG is recommended.
Recommended fuel composition is fuel with a minimum fuel energy of 2500
BTU's/ft³ with maximum propylene content of 5% and butane and heavier gas
content of 2.5% and minimum propane content of 90%.
NG or LPG engines are certified to operate on natural or liquid propane gas. The
emissions control system for this engine is EM (Engine Modifications).
WARNING
The equipment is equipped with an automatic safety gas "fuel lock-off" valve. If the "fuel
lock-off" valve is damaged or missing, do not operate the equipment.
Add Fuel
WARNING
Fuel vapors are flammable and explosive. Fire or explosion could result in burns
or death.
When you add fuel
• Fill the fuel tank outdoors or in an area that has good airflow.
• Frequently examine the fuel lines, fuel tank, and connections for cracks or leaks.
Replace damaged parts.
For information on refueling natural or LP gas engines, read the operating instructions
supplied by the equipment manufacturer.

faster than you can let go. Broken bones, fractures, bruises or sprains could result. To
prevent kickback when you start the engine, pull the starter cord slowly until resistance
is felt and then pull quickly.
