Inspect Fuel
System / Check for
Leaks Inspect fuel system & check for leaks BEFORE starting generator.
Do not start generator until all needed repairs have been completed.
WARNING: Fuel leak hazard
Gasoline, LP gas (propane) and NG (natural gas) are highly
explosive and fuel leaks can result in fire or explosions. You can be
burned and seriously injured if the fuel system is not properly
hooked up or there is a fuel leak when you start the engine.
1) Inspect the entire fuel system. Look for: Signs of leaks or deterioration,
chafed or spongy fuel hose, loose connections, loose or missing fuel hose
clamps, a damaged gasoline tank, or a defective gasoline shut-off valve.
2) If you are using LPG or NG, check for leaks after opening supply valve:
a) Leak test method. Test for leaks on a regular basis by applying a
soap and water solution over pipes, hoses, and connections. Soap
bubbles will form if there is a leak. Use this method to test after each
reconnection to NG/LPG supply (for example, after moving the
generator), and on a regular basis thereafter. This method will help
you detect small leaks.
b) Also beware of gas odor. Both LP and NG have an odorant added
(rotten egg/sulfur smell) that will aid in the detection of more
dangerous quantities of leaking gas. Note:
• Natural gas. Natural gas is lighter than air and tends to collect in
high areas.
• LP gas (propane). LP gas is heavier than air and tends to settle in
low areas. Smell next to floor for gas.
If you smell gas, DO NOT start engine! DO NOT light a match. DO NOT
flip on an electrical switch. If possible, shut off LPG or NG
supply. Exit area immediately and call gas supplier or fire department.
Personal Protection 1) Hearing can be damaged from prolonged, close-range exposure to the
type of noise produced by this generator. The use of ear plugs or other
hearing protection device is recommended for persons working within
15-20 feet of the running generator for an extended period of time.
2) Loose or dangling apparel can become entangled in moving parts. Metal
jewelry can conduct electricity. Never wear jewelry or loose-fitting
clothing when starting or operating the generator.
