Engine Break-In
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.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting, 
emission, and durability performance up to 1,100 feet above sea level 
(ASL) (96.0 kPa). To maintain proper engine operation and emission 
compliance above 1,100 feet ASL the carburetor may need to be ad-
justed by an authorized ECHO service dealer.
IMPORTANT 
If the engine is adjusted for operation above 1,100 feet ASL, the 
carburetor must be re-adjusted when operating the engine below 
1,100 feet ASL, otherwise severe engine damage may result.
