ELECTRIC STARTER & START BUTTON 

The electric starter will start a properly choked and 
primed engine when start button (120V AC) is pushed.

To start the machine, connect the electric starter to 
an electric power source with an approved extension 
cord and press the start button.

Thoroughly inspect the electrical cord before 
using the machine. If the cord is damaged, do 
not operate the machine. Replace or repair the 
damaged cord immediately.

Connect extension cord to the electric starter 

plug-in first and then to a power outlet; disconnect 
the extension cord from the power outlet first and 

then from the machine.

To prevent damaging the electric starter, do not 
run it more than 5 continuous seconds each time 
you try to start. Wait 10 seconds between each 
attempt.
