KNOW YOUR ENGINE
CONTROLS
FUEL VALVE LEVER
The fuel valve opens and closes the passage between the fuel
tank and the carburetor.
The fuel valve lever must be in the ON position for the engine to run.
When the engine is not in use, leave the fuel valve lever in the
OFF position to prevent carburetor flooding and to reduce the
possibility of fuel leakage.
THROTTLE LEVER
The throttle lever controls engine speed.
Moving the throttle lever in the directions shown makes the
engine run faster or slower.
ENGINE SWITCH
The engine switch enables and disables the ignition system.
The engine switch must be in the ON position for the engine to run.
Turning the engine switch to the OFF position stops the engine.
CHOKE LEVER
The choke lever opens and closes the choke valve in the
carburetor.
The CLOSE position enriches the fuel mixture for starting a cold
engine.
The OPEN position provides the correct fuel mixture for
operation after starting, and for restarting a warm engine.
Some engine applications use a remotely mounted choke control
rather than the engine-mounted choke lever shown here.
CHECK BEFORE OPERATION
IS YOUR ENGINE READY TOGO?
For your safety, and to maximize the service life of your
equipment, it is very important to take a few moments before you
operate the engine to check its condition. Be sure to take care
of any problem you find, or have your servicing dealer correct it,
before you operate the engine.

The Oil Alert system (applicable engine types) will automatically
stop the engine before the oil level falls below safe limits.
However, to avoid the inconvenience of an unexpected shutdown,
always check the engine oil level startup.
Check the air filter. A dirty air filter will restrict air flow to the
carburetor, reducing engine performance.
Check the fuel level. Starting With a full tank Will help to eliminate
or reduce operating interruptions for refueling.

Refuel in a well-ventilated area starting the engine. If the
engine has been running, allow it to cool. Refuel carefully to avoid
spilling fuel. DO not fill above the fuel strainer shoulder. After
refueling, tighten the fuel tank cap securely.
Never refuel the engine inside a building where gasoline fumes
may reach flames or sparks. Keep gasoline away from appliance

A CAUTION
Be careful not to spill fuel when
filling your fuel tank. Damage caused by spilled fuel is not
covered under warranty.
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of 86 or
higher.
These engines are certified to operate on unleaded gasoline.
Unleaded gasoline prcxiuces fewer engine and spark plug desx)sits
and extends exhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline
mixture. Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light “spark knock” or “pinging”
(metallic rapping noise) while operating under heavy loads. This is
no cause for concern.
