Adjusting The Carburetor

WARNING!

The cutter attachment must

never oscillate at engine idle speed. If

the idle speed cannot be adjusted by

the procedures described here, return

the trimmer to your Shindaiwa dealer

for inspection.

The engine must return to idle speed

whenever the throttle trigger is released.

Idle speed is adjustable and must be set

low enough to permit the engine clutch

to disengage the cutter attachment when

throttle trigger is released.

Check and Adjust Idle Speed

1. Start the engine and allow it to idle two

or three minutes, or until it warms up.

2. If the cutter attachment oscillates

at engine idle, reduce idle speed

by turning the idle adjusting screw

counter-clockwise as necessary.

IMPORTANT!

Use a tachometer, if one is available, to

set engine idle. Standard idle speed is:

2,750 (±250) min

-1

adjustment screw clockwise.

STOP position.

The mixture of the carburetor on this unit
