WARNING
Accidental starts can cause severe injury or death.
Disconnect and ground spark plug leads before
servicing.
Before working on engine or equipment, disable engine as
follows: 1) Disconnect spark plug leads. 2) Disconnect
negative (–) battery cable from battery.
Before disconnecting negative (–) ground cable, make
sure all switches are OFF. If ON, a spark will occur at the
ground cable terminal which could cause an explosion if
hydrogen gas or LPG/NG fuel vapors are present.
WARNING
Risk of Fire. Can cause severe injury or death.
Do not smoke or permit flames or sparks near fuels or the
fuel system.
Servicing the fuel system. A flash fire can cause
severe injury or death. Do not smoke or permit flames or
sparks near the carburetor, fuel line, fuel filter, fuel pump,
or other potential sources of spilled fuels or fuel vapors.
Catch fuels in an approved container when removing the
fuel line or carburetor.
Servicing the air cleaner. A sudden backfire can cause
severe injury or death. Do not operate the engine with
the air cleaner removed.

WARNING
Rotating parts can cause severe injury.
Stay away while the engine is in operation.
Keep hands, feet, hair, and clothing away from all moving
parts to prevent injury. Never operate the engine with
covers, shrouds, or guards removed.
WARNING
Carbon monoxide can cause severe nausea, fainting,
or death.
Avoid inhaling exhaust fumes.
Engine exhaust gases contain poisonous carbon
monoxide. Carbon monoxide is odorless, colorless, and
can cause death if inhaled.
WARNING
Explosive fuel vapors. Can cause severe injury or
death.
Use extreme care when handling, storing, and using
fuels.
Gas fuel leaks. Explosive fuel vapors can cause severe
injury or death. Fuel leakage can cause an explosion.
Check the LPG vapor or natural gas fuel system for
leakage by using a soap and water solution with the fuel
system test pressurized to 6–8 ounces per square inch
(10–14 inches water column). Do not use a soap solution
containing either ammonia or chlorine because both
prevent bubble formation. A successful test depends on
the ability of the solution to bubble.
