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.

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.
