NOTE
This model is equipped with an EPA
approved carburetor with no mixture
adjustment.
IMPORTANT!
Use a tachometer, if one is available, to
set engine idle. Standard idle speed is:
2,750 (±250) rpm (min
-1
).
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 rotates at
engine idle, reduce idle speed by
turning the idle adjusting screw
counter-clockwise as necessary.
See Figure 23.
3. If the engine is stalling and won’t
idle, increase idle speed by turning
the idle adjustment screw clockwise.
