MAINTENANCE
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.
1.
Before adjusting the
carburetor, clean or replace
the air filter and spark arrestor
screen.
2.
Start engine and run for
several minutes to reach
operating temperature.
3.
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; counter clockwise to
decrease idle speed.
When carburetor adjustment is completed, the cutting
attachment should not move at idle, otherwise serious personal
injury may result.
