Echo HCA-265 Manual De Usuario

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.

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.

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.

Tools required:   Screwdriver, Tachometer (ECHO P/N 99051130017)

Parts required:    None

Every unit is run at the factory and the carburetor is set in compli-

ance 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  avail-

able, idle speed screw (A) should be set to the specifications found 

on page 28 “Specifications” of this manual. Turn idle screw (A) 

clockwise to increase idle speed; counter clockwise to decrease 

idle speed.

When carburetor adjustment is completed, the cutting attachment 

should not turn at idle, otherwise serious personal injury may 

result.
