Exhaust emissions are controlled by the
design of the engine and components
(e.g. carburation, ignition, timing and
valve or port timing).
The carburetor has been set at the
factory to provide an optimum fuel-air
mixture under most operating
conditions.
Adjusting Idle Speed
Engine stops while idling
N
Warm up the engine for about
3 minutes.
N
Turn the idle speed screw (LA)
slowly clockwise until the engine
runs smoothly – the cutting blades
must not run.
Cutting blades run when engine is idling
N
Turn the idle speed screw (LA)
counterclockwise until the cutting
blades stop running and then turn
the screw about another 1/2 to 3/4
turn in the same direction.
WARNING
If the cutting blades continue moving
when the engine is idling, have your
power tool checked and repaired by your
servicing dealer.
If there is a loss of engine power, the
machine is difficult to start or runs poorly
at idle, first check the spark plug.
Install a new spark plug after
approximately 100 operating hours or
earlier if the electrodes are
eroded/corroded.
The wrong fuel mix (too much engine oil
in the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition
of the spark plug. These factors cause
deposits to form on the insulator nose,
which may degrade performance.
Removing the Spark Plug
N
Shut off the engine.
N
Remove the spark plug boot (1).
N
Unscrew the spark plug (2).
