canrestricttheageoftheoperator.

•Nevermowwhilepeople,especiallychildren,orpets
arenearby .

•Keepinmindthattheoperatororuserisresponsible
foraccidentsorhazardsoccurringtootherpeopleor
theirproperty.

•Donotcarrypassengers.

•Alldriversshouldseekandobtainprofessional

emphasize:

–theneedforcareandconcentrationwhen

workingwithride-onmachines;

–controlofaride-onmachineslidingonaslope
