VI. Stopping Your Engine and
Short-Term Storage
Stop engine according to equipment manufacturer’s
instructions.
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
provided. Failure to do so may lead to serious injury or
death.
NEVER store engine with fuel in the
fuel tank inside a building with
potential sources of ignition such as hot water or space
heaters, clothes dryers, electric motors, etc. Doing so may
lead to an explosion resulting in death or serious injury.
VII. Maintenance
To avoid serious injury or death, 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.
NOTE
The Twin Cylinder Engines have
two
spark plug
connections.
To prevent accidental starting when
working on equipment, always:
• Carefully disconnect spark plug wire and keep it
away from spark plug. See “G. Avoid Accidental
Starts” instructions on page 2. Afterward, continue
reading instructions below.
• Keep the disconnected spark plug wire
securely away from metal parts where arcing
could occur.
• Carefully attach the spark plug wire to the
grounding post, if provided.
• Disconnect battery at negative terminal first, if
engine is equipped with a DC electric starter.
• Turn all engine switches to “OFF” position.
• Remove ignition key, if provided.
A. Changing Oil
To avoid engine damage, it is important to:
• Check oil level before each use and every 5
operating hours when engine is warm. See
"A. Checking Oil Level" instructions on page 4.
Afterward, continue reading instructions below.
• Change oil after first 2 operating hours and every 50
operating hours thereafter; more often if operated in
extremely dusty or dirty conditions. Engine should
still be warm but NOT hot from recent use.
