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 Shindaiwa service dealer.
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 Shindaiwa 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.

correct idle speed.
Adjusting Engine Idle
The engine must return to idle speed
whenever the throttle lever is re-
leased. Idle speed is adjustable, and
must be set low enough to permit the
engine clutch to disengage the cutting
attachment.
Idle Speed Adjustment
Place the trimmer on the ground, 1.
then start the engine, and then
allow it to idle 2-3 minutes until
warm.
If the attachment moves when the 2.
engine is at idle, reduce the idle
speed by turning the idle adjust-
ment screw counter-clockwise.
WARNING!
The cutting attachment
must NEVER move at engine idle!
If the idle speed cannot be adjusted
by the procedure described here,
return the unit to your Shindaiwa
dealer for inspection.
