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
1,100 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.
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 Shindaiwa dealer..
WARNING!
When carburetor adjustment is completed, the cutting attachment should not move at idle, otherwise serious
personal injury may result.

Adjusting Engine Idle

The engine must return to idle speed whenever the throttle lever is released.
Idle speed is adjustable, and must be set low enough to permit the engine
clutch to disengage the cutting attachment.
WARNING!
The cutting attachment must NEVER rotate at engine idle! If the
idle speed cannot be adjusted by the procedure described here, return
the trimmer to your Shindaiwa dealer for inspection.

Idle Speed Adjustment

1. Place the trimmer on the ground, then start the engine, and then allow it to
idle 2-3 minutes until warm.
2. If the attachment rotates when the engine is at idle, reduce the idle speed
by turning the idle adjustment screw (A) counter-clockwise.
3. If a tachometer is available, adjust idle. Check Specifications page for cor-
rect idle speed.
Carburetor fuel mixture adjustments are preset at factory and cannot be ser-
viced in the field
