The blades must not move at idle, otherwise serious personal injury 

may result. Periodic carburetor adjustment may be necessary to as-

sure blades do not move at idle.  

If blades move, readjust carburetor according to these instructions, 

or see your ECHO Dealer  

New engines must be operated a minimum duration of two tanks of fuel 

break-in before carburetor adjustments can be made. During the break-

in period your engine performance will increase and exhaust emissions 

will stabilize. Idle speed can be adjusted as required.
