Starting and Stopping

 

Before Starting the Engine 

1. Fill the fuel tank as instructed in the Before Operation section of   

  this manual. 

2. Rest the Multi-cutter on the ground. 

3. Make sure the cutting attachment is clear of any broken glass,   

    nails, wire, rocks or other debris. 

4. Keep all bystanders, children and animals away from the working   

  area. 

 

Cold Starting Procedure

 

 
The carburetor on this engine is equipped with a fuel primer and a 

choke system. 

To start a “cold” engine properly, perform the following procedure: 

1. Pump the primer bulb until fuel can be seen flowing through 
    the fuel return line to the fuel tank. Flowing fuel should be   
    almost clear, not foamy or full of bubbles.

 

2. Turn the choke lever to the Close “

” position.   

3. With the stop switch “ON” , and the throttle trigger positioned at   

    Fast-idle start position, pull the starter grip. After the engine is   

    started, turn the choke lever to the Open “

” position. Then   

    squeeze and release the throttle trigger to allow it to return   

  to the idle position. 

If the engine stops running before you turn   

the choke lever to the Open “

” position : 

Go ahead and open the choke, pull the starter   

grip with the throttle trigger positioned at   

Fast-idle

 

start position.
