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.
1. Move remote control on equipment, or engine mounted
control, or any ignition stop switch on engine, to
“STOP” or “OFF” position, if present (see equipment
manufacturer’s instructions). See Figures 6, 10 and 15
beginning on page 5. Afterward, continue reading
instructions below.
2. Close air vent screw on fuel fill cap, if present (see
equipment manufacturer’s instructions). See Figure 7
on page 5. Afterward, continue reading instructions
below.
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.
The exhaust deflector and other
engine parts become extremely hot
during operation and remain hot after the engine has
stopped. To avoid severe burns on contact, STAY AWAY
from these areas.
To prevent accidental starting when
working on equipment, always:
• Carefully disconnect spark plug wire and keep it
away from spark plug. See Figures 16 and 17.
• 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.
