WARNING
Tip-Over Hazard
A child or adult can tip the range and be killed.
Verify the anti-tip bracket has been properly installed
so the foot is secure in the anti-tip bracket.
Ensure the anti-tip bracket is re-engaged when the range
is moved so the foot is secure into the bracket.
Do not operate the range without the anti-tip bracket in
place and engaged.
Failure to follow these instructions can result in death or
serious burns to children or adults.
