Honda F720 Owner's Manual page 27

Do not use the tiller with a rotor whose diameter is in excess of
360 mm.
Operating the tiller on grades could cause the tiller to tip over.
Allowing any one to operate this tiller without proper instruction
may result in injury.
Wear sturdy, full coverage footgear. Operating this tiller with bare
feet, or with open toe shoes or sandals increases your risk of injury.
Do not use the tiller in the night.
Be sure to use two people to transport the tiller from one place to
another without using a carrier.
When the rotor is clogged with mud, pebbles etc., immediately stop
the engine and clean the rotor in a safe place. Be sure to wear heavy
gloves when cleaning the rotor.
To prevent damage, check the tiller for any signs of damage or
other faults each time the tiller is used after it has been operated
last.
