Stopping The Engine; Adjust Engine Idle; Idle Speed Adjustment - Shindaiwa 502s Manual Del Operador

Starting a Flooded Engine
If the carburetor choke is closed (choke
control fully extended) and after repeated
attempts, the engine fails to start, the
engine may be flooded with fuel. The fol-
lowing steps are recommended to clear a
flooded engine.
1. Move the "ON-OFF" ignition control
switch to the "OFF" position.
WARNING!
The ignition switch must be
in the "OFF" position to prevent the
chance of igniting fuel and/or fuel
vapors escaping from the engine
during this procedure.
2. Push the choke control completely in
to open the choke.
3. Remove the spark plug access cover
and disconnect the plug wire. Remove
the spark plug.

4. Inspect the spark plug for damage or
excessive wear and replace if neces-
sary. If the spark plug electrode is fuel
soaked, or coated with carbon depos-
its, clean and set the plug gap. Refer
to the Specifications section for spark
plug information.
WARNING!
Keep clear of the spark
plug opening! Any excess fuel in the
engine will be ejected through the
spark plug opening during starter
operation.
5. With the spark plug removed, the
choke control pushed in and the igni-
tion control in the "OFF" position, clear
any excess fuel in the engine by repeat-
edly pulling the starter until no evi-
dence of fuel is seen escaping from the
spark plug opening.
1. Move the "ON-OFF" ignition control
switch to the off position. If the saw has
just been used, allow the engine to idle
for 1 to 2 minutes to stabilize engine
operating temperature before stopping
the engine.
