Stop and cool the engine before adding fuel.
DO NOT SMOKE!

SAFETY GUARDS: It is the owner's
responsibility to ensure that all guards and
shields are in place and in working order.

IGNITION SYSTEMS: Breakerless, magneto,
and battery ignition systems can cause severe
electrical shocks. Avoid contacting these
units or their wiring.
