Starting A Flooded Engine
1. Disconnect the spark plug lead and use
the spark plug wrench to remove the
spark plug (turn counter clockwise to
remove).
2. Slide the ignition switch to the "O"
(STOP) position.

If the spark plug is fouled or
soaked with fuel, clean the plug as
necessary.

Stopping the Engine

Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the "O" (Engine OFF) position.

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.

Idle Speed Adjustment

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 Swisher dealer for
inspection.
3. Open the choke and fully depress the
throttle lever with your left hand, then
pull the starter handle rapidly with your
right hand to clear excess fuel from the
combustion chamber.
4. Reinstall the spark plug and tighten it
firmly. If a torque wrench is available,
torque the spark plug to 148–165 in.-lb
(170–190 kg/cm).

by turning the idle adjustment screw
counter-clockwise.
