CAUTION: Muffler and other engine
parts become extremely
hot during operation and

WARNING: This lawn mower is equipped
with an internal com bus tion engine and
should not be used on or near any un im-
proved forest-covered, brush-covered or
grass-cov ered land unless the engine's
exhaust system is equipped with a spark
arrester meeting applicable local or state

should be maintained in effective working
order by the operator.
In the state of California the above is required
by law (Section 4442 of the California Public

I. CHILDREN
WARNING: CHILDREN CAN
BE SERIOUSLY INJURED OR

the safety instructions below.
The American Academy of Pediatrics recom-
mends that children be a minimum of 12 year
of age before operating a pedestrian con-
trolled lawn mower and a minimum of 16 years
of age before operating a riding lawn mower.
Tragic accidents can occur if the op er a tor is
not alert to the presence of children. Children
are often attracted to the ma chine and the
mowing activity. Never assume that children
will remain where you last saw them.
• Keep children out of the mowing area and
under the watchful care of a re spon si ble
adult other than the operator.
• Be alert and turn machine off if chil dren
enter the area.
• Before and while walking back wards, look
behind and down for small chil dren.
• Never allow children to operate the ma-
chine.
