Instructions For A Safe Operation
DANGER ! Explain the instructions below to your child:
Right after seeing the vehicle, your child will want to drive it
immediately. Children are not capable of judging, realizing and
assessing dangers. Unsupervised operations can lead to serious
injuries. Before letting your child drive the vehicle, you must check
the area and your child’s ability to judge and drive the vehicle
safely. Even if children are instructed before, they are not capable
of foreseeing the dangers and turning away from them. There are
no other directly supervision options for adults. Set up safety rules
adapted to local conditions alongside the instructions below about
using the vehicle. Ensure that these instructions are followed. All
of these rules must be obeyed by the children who will play with
your child as well.
Instructions for a safe operation:
Ensure that children learn and obey the rules below:
1. Always sitting properly on the seat.
2. No driving without sturdy shoes.
3. Only one (1) child must get on the vehicle. If the child sits
improperly or stands in the vehicle, he/she may fall off; the
vehicle may overturn and this may lead to serious injuries.
4. Do not allow your child to drive the vehicle in the streets or
roads where motored vehicles are driven.
5. Do not allow your child to drive the vehicle near swimming
pools, ponds, barriers (e.g: furniture, trees with low branches
