Before Operation

PRE-OPERATION CHECKS

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.
WARNING
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 pre-operation inspection before each operation and correct any problem.
Before beginning your pre-operation checks, be sure the engine is level and the engine switch is in the STOP position.
Check the General Condition of the Engine
• Remove any excess dirt or debris, especially around the heat shield, recoil starter, and cylinder head fins.
• Inspect for signs of damage and oil leakage.
• Be sure all shields and covers are in place. All nuts, bolts, and screws must be tight.
Check the Engine
• Check the engine oil level. Running the engine with a low oil level or improper oil can cause engine damage. To avoid the
inconvenience of an unexpected shutdown, always check the engine oil on a level surface before startup. Engine may be shipped
with or without oil. 5W-30 oil is recommended for general use. Synthetic oil is an acceptable alternative (refer to Engine Oil Level
Check (page 9) for proper engine oil levels).
• Check the fuel level before start-up. Since the engine must be cool before refueling, starting with a full tank will help to eliminate or
reduce operating interruptions for refueling.
Electric Start
• Determine what type of power source outlet you will be connecting the power cord to. If the starter is equipped with a 120V AC
electrical requirement, make sure to use the appropriate 120V AC household current input.
• Determine if your power source has a Ground Fault Interrupt (GFI) three-wire system by consulting with a licensed electrician.
If your power source does not have a GFI three-way ground system, DO NOT USE THE ELECTRIC STARTER due to a possible
hazardous condition.
