Use of gasoline with an ethanol content greater than 10% can damage
the engine and fuel system and will void the manufacturer's warranty.
When refueling, keep it away from cigarettes, open flames, smoke and/
or sparks.
Do not touch the spark plug while the engine is operating or shortly after
the engine has been shut down.
Know how to stop the engine quickly and understand operation of all
the controls. Never permit anyone to operate the engine without proper
instructions.
Do not operate in rain or snow.
To avoid breathing in poisonous carbon monoxide from the exhaust
gases, adequate ventilation should be provided if running in a partially
enclosed space.
If stored outdoors, check all electrical components before each use.
Moisture can damage the eletronics and can lead to an electric shock.
Do not connect an extension to the exhaust pipe.
If you start to feel sick, dizzy, or weak after the engine has been running,
move to fresh air RIGHT AWAY. See a doctor. You could have carbon
monoxide poisoning.
1.3 AC SAFETY
WARNING!
Before connecting the snowthrower to an electrical device or power cord:
Make sure that everything is in proper working order. Faulty devices or
power cords can lead to an electrical shock.
Turn off immediately if the device begins to operate abnormally. Then
disconnect and investigate the problem.
Use only a three-conductor power cord properly grounded to the power
source.
Use a tough rubber sheathed flexible cable (according to IEC245 or
equivalent standards). The maximum length of the extension cable: 196
feet (60 meters) for cable of 15.5 gauge (1.5mm²); 328 feet (100 meters)
