FOR YOUR SAFETY

provided important safety messages in this manual and on the snow 
blower. This information alerts you to potential hazards that could hurt 
you or others. Please read these messages carefully.

Of course, it is not practical or possible to warn you about all the 
hazards associated with operating or maintaining a snow blower. You 
must use your own good judgment.

what you can do to avoid or reduce injury.
These signal words mean:

Important Message to Parents

The safety of your children is very important to Honda. Snow blowers 
are tools, not toys. As with any equipment, bad judgments can result 
in serious injuries. Your child must be big enough, strong enough, and 
have the coordination necessary to comfortably reach and operate the 
controls. Anyone who takes unnecessary risks and doesn’t obey rules 
should not operate this snow blower.

Safety Label Locations

These labels warn you of potential hazards that can cause serious 
injury. Read them carefully. If a label comes off or becomes hard to 
read, contact an authorized Honda servicing dealer for a replacement.
