CHECK BEFORE OPERATION

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.

Before beginning your preoperation checks, be sure the engine is 
level and the engine switch is in the OFF position.

CHECK THE GENERAL CONDITION OF THE ENGINE

  

Look around and underneath the engine for signs of oil or 

gasoline leaks. 

  

Remove any excessive dirt or debris, especially around the 

muffler and recoil starter. 

 

Look for signs of damage. 

  

Check that all shields and covers are in place, and all nuts, bolts, 

and screws are tightened.

CHECK THE ENGINE

Check the engine oil level. Running the engine with a low oil level 
can cause engine damage. 

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 before 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.

CHECK THE EQUIPMENT POWERED BY THIS ENGINE

Review the instructions provided with the equipment powered 
by this engine for any precautions and procedures that should be 
followed before engine startup.

IS YOUR ENGINE READY TO GO?

Improperly maintaining this engine, or failing to 
correct a problem before operation, could cause a 
malfunction in which you could be seriously injured.

Always perform a preoperation inspection, and correct 
any problem.

STARTING THE ENGINE

Move the fuel valve lever to the ON position.

To start a cold engine, move the choke lever to the CLOSE 
position.

OPERATION

Before operating the engine for the first time, please review the 

IMPORTANT SAFETY INFORMATION and the chapter titled 
BEFORE OPERATION.

Review the instructions provided with the equipment powered 
by this engine for any safety precautions that should be observed 
in conjunction with engine startup, shutdown, or operation.

SAFE OPERATING PRECAUTIONS

Carbon monoxide gas is toxic. Breathing it can cause 
unconsciousness and even kill you.  

Avoid any areas or actions that expose you to carbon 
monoxide.
