- Never stick your hands in the snowblower! If snow jams the snowblower, stop the engine and wait more than 5 seconds. Use a solid object to clear wet snow or debris from the chute. Beware of the recoil of the motor and blades after the machine has been turned off.
- Proper supervision. Do not leave the snow blower unattended when it is running. Shut off the engine if you must walk away from the machine.
- Safe fueling. Add fuel before starting the snow blower. Never add fuel when the engine is running or hot. Do not operate the machine in an enclosed area.
- Avoid the engine. Stay away from the engine. It can become very hot and burn unprotected flesh.
- Watch the snowblower cord. If you are operating an electric snow blower, be aware of where the power cord is at all times.
- No tampering. Do not remove safety devices, shields, or guards on switches, and keep hands and feet away from moving parts.
- Watch for motor recoil. Beware of the brief recoil of motor and blades that occurs after the machine has been turned off.
- Keep children away. Never let children operate snowblowers. Keep children 15 years of age and younger away when snowblowers are in use.
- Understand your machine. Read the instruction manual prior to using a snowblower. Be familiar with the specific safety hazards and unfamiliar features. Do not attempt to repair or maintain the snowblower without reading the instruction manual.
