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 adjusted by an
authorized ECHO service dealer.
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.
Level 2.
Parts Required:
Note: Every unit is run at the factory and the carburetor is set in
compliance with emission regulations. Carburetor
adjustments, other than idle speed, must be performed by an
authorized ECHO dealer.
Before adjustment make sure that:
• Air filter is clean and properly installed.
• Spark arrestor screen is free of carbon.
• Blower pipes are installed.
1. Start engine, run at idle for one
minute.
2. Complete warm up by running
at full throttle for 5 minutes,
operating choke twice to clear
air from carburetor chambers.
3. Check idle speed and reset if
necessary. If a tachometer is
available, idle speed screw (A)
