High Altitude Operation

This engine has been factory adjusted to maintain satisfactory starting and

durability performance up to 330 m (1100 ft.) above sea level (ASL) (96.0

kPa). To maintain proper engine operation and emission compliance above

330 m (1100 ft.) ASL the carburetor may

need to be adjusted by an

authorized ECHO service dealer.

If the engine is adjusted for operation above 330 m (1100 ft.) ASL, the

carburetor must be re-adjusted when operating the engine below

330 m (1,100 ft.) ASL, otherwise severe engine damage may result.

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.

1. Check idle speed and reset if

necessary. If a tachometer is

available, idle speed screw (A)

should be set to the

specifications found on

“Specifications” page of this

manual. Turn idle screw (A)

clockwise to increase idle

speed; counterclockwise to

decrease idle speed.

When carburetor adjustment is completed, the cutting

attachment should not move at idle, otherwise serious personal

injury may result.
