COMPONENT & CONTROL LOCATION

BEFORE OPERATION CHECKS 

IS YOUR ENGINE READY TO GO?

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 throttle lever (ignition switch lever or engine stop switch) is in 
the STOP position.

Always check the following items before you start the engine:

1. Fuel level (see page 5).

2. Oil level (see page 5).

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.

3. Air cleaner (see page 6).

4. General inspection: Check for fluid leaks and loose or damaged 

parts.

5. 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.
