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 cutters.

Adjusting Engine Idle

Stopping the Engine

1.  Cool the engine by allowing it to idle for 

–3 minutes.

.  Move the ignition switch to the “O” or 

STOP position. See Figure 11.

WARNING!

The cutters must NEVER engage at 
engine idle speeds! If the idle speed 
cannot be adjusted by the above  
procedure, return the trimmer to your 
dealer for inspection.

1.  Start the engine, and then allow it to idle 

–3 minutes until warm.

.  If the cutters move when the engine is 

at idle, reduce idle speed by turning the 

idle adjustment screw counterclockwise.

3.  If a tachometer is available, the engine 

idle speed should be final-adjusted to 

3,000 ±50 rpm (min

-1

).

4.  Carburetor fuel mixture adjustments 

are preset at the factory and cannot be 

adjusted or serviced in the field.

Starting a Flooded Engine

CAUTION!
Incorrect spark plug installation can 
damage the engine!

1.  Disconnect the spark plug lead, and 

then use the spark plug wrench to 

loosen and remove the spark plug.

.  If the spark plug is fouled or is soaked 

with fuel, clean or replace the plug as 

necessary. For spark plug specifications 

and gapping procedure, see page 9.

3.  With the spark plug removed, crank the 

engine several times to clear excess fuel 

from the combustion chamber.

 WARNING!

Burn danger from hot engine! Allow 
engine to cool before removing  
cylinder cover.

4.  Replace the spark plug and tighten it 

firmly with the spark plug wrench. If a 

torque wrench is available, torque the 

spark plug to 170-190 kg cm.

5.  Repeat the starting procedures for a 

warm engine.

6.  If the engine still fails to start or fire, 

refer to the troubleshooting chart at the 

end of this manual.
