To avoid unsupervised operation of
an engine, especially by children,
NEVER leave it unattended when it is running. Always turn
off the engine after use and remove ignition key, if

VII. Maintenance
An adult should perform maintenance
on this engine. Only allow children to
perform maintenance if an adult has determined they are
experienced and capable of such operation.
To prevent accidental starting when working on equipment,
always:
• Disconnect spark plug wire and keep it away from
spark plug. See "G. Avoid Accidental Starts"
instructions on page 2.
• Keep the disconnected spark plug wire
securely away from metal parts where arcing
could occur.
• Attach the spark plug wire to the grounding
post, if provided.
• Disconnect battery at negative terminal first, if
engine is equipped with an electric starter.
• Turn off all engine switches.
• Remove ignition key, if provided.

A. Checking and Changing Oil

• Check oil level before each use and after every
5 operating hours when engine is warm.
See "A. Checking Oil Level" instructions on page 4.
• Change oil after first 2 operating hours and every 25
operating hours thereafter; more often if operated in
extremely dusty or dirty conditions. Engine should
still be warm but not hot from recent use.
1. Be sure you find the correct drain plug location, if
