● These safety precautions are to prevent you and those in the vicinity from
incurring harm or damage. Make sure to observe these precautions and to
constantly strive to ensure safety.
● Safe use of the engine is your personal obligation and responsibility.
Constantly take care to act with good judgment as you enjoy your hobbies.
•Make sure never to touch the propeller when it is rotating. Also make sure
that the propeller does not come in contact with the ground or with
anything in its surroundings. Doing so could result in grave injury.
• The fuel is toxic. Do not let it get into your eyes or mouth. Store it in a cool
place, out of the reach of infants and children. Improperly handled, it is a
health hazard.
• Use of open flames around the fuel is prohibited, owing to the danger of
fire occurring.
• To prevent burns, make sure not to touch the engine while it is operating
or immediately after it has stopped.
• Do not run the motor in poorly ventilated places. When running it outside,
do not breathe the exhaust, as it is a health hazard.

• Special caution must be taken with all propellers used. Make sure to use
them correctly, in keeping with the manufacturers’ operating manuals, etc.
Failure to do so could result in injury.
• Please wear clothing that facilitates your safety. Remove all scarves, overly
long sleeves, neckties and the like. Failure to do so could result in injury.
• Please check to ensure that the direction in which the engine’s throttle
linkage operates and the amount it operates are correct. Failure to do so
could result in engine damage.
•When starting the engine, make sure to be wearing protective eyewear and
gloves and to use the starter. Failure to do so could result in injury.
•Do not run the motor on sandy soil or where there is a lot of gravel. Doing
so could result in injury.
• When mounting the engine to a model, make sure to follow the model’s
operating manual. If necessary, reinforce the engine mounting unit and the
peripheral parts.
