Engine Break-In
New engines must be operated a minimum of two tanks of fuel 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.
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 ad-
justed by an authorized ECHO service dealer.
IMPORTANT
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:
None.
NOTE
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 "Specifications" page of this manual. Turn idle screw (A)
clockwise to increase idle speed; counter clockwise to decrease
idle speed.
WARNING
When carburetor adjustment is completed, the cutting attachment
should not move at idle, otherwise serious personal injury may
result.
