BEFORE OPERATION CHECKS
IS YOUR ENGINE READY TO GO?
For your safety, to ensure compliance with environmental regulations,
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 pre-operation checks, be sure the engine is level
and the engine switch is in the OFF position.
Always check the following items before you start the engine:
Check the General Condition of the Engine
1. Look around and underneath the engine for signs of oil or gasoline
leaks.
2. Remove any excessive dirt or debris, especially around the muffler
and recoil starter.
3. Look for signs of damage.
4. Check that all shields and covers are in place, and all nuts, bolts, and
screws are tightened.
Check the Engine
1. Check the fuel level (see page 8). Starting with a full tank will help to
eliminate or reduce operating interruptions for refueling.
2. Check the engine oil level (see page 9). Running the engine with a
low oil level can cause engine damage.
The ‘‘Oil Alert’’ buzzer (applicable types) will warn you when engine
oil needs to be added to the crankcase. If the buzzer sounds, stop the
engine and add oil.
3. Check the air filter element (see page 10). A dirty air filter element will
restrict air flow to the carburetor, reducing engine performance.
4. 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.
