Carburetor Adjustment - Echo SHAFT HEDGE CLIPPER HCA-265 Operator's Manual

CARBURETOR ADJUSTMENT

Engine Break-In
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.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 1,000 feet above mean sea
level (MSL). To maintain proper engine operation above 1,000 feet
MSL the carburetor must be adjusted by an authorized ECHO service
dealer.
IMPORTANT
If the engine is adjusted for operation above 1,000 feet MSL, the
carburetor must be re-adjusted when operating the engine below
1,000 feet MSL, otherwise severe engine damage can result.
Level 3.
Tools required: Screwdriver, Tachometer (ECHO P/N
99051130017)
Parts required: None
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 page 27 "Specifications" 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 turn at idle, otherwise serious personal
injury may result.
