Built-in function in order to facilitate steering. The
operator only has to turn the steering wheel gently.

If the machine is left unattended, re-
move the lead from the spark plug. Also

The engine may be very warm immedi-
ately after it is shut off. Do not touch the
silencer, cylinder or cooling flanges.
This can cause burn injuries.
Do not park in close proximity to in-
flammable objects. Do not cover the
machine until the catalytic converter
