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 MultiTool must
not run.
MultiTool runs when the engine is idling
N Turn the idle speed screw (LA)
counterclockwise until the MultiTool
stops moving and then turn the
screw about another 1/2 to 3/4 turn
in the same direction.
WARNING
If the MultiTool continues to run when
the engine is idling, have your machine
checked and repaired by your servicing
dealer.
N If the engine is down on power,
check the spark arresting screen in
the muffler.
N Wait for the muffler to cool down.
N Use the combination wrench to
unscrew the spark arrestor.
N Clean the spark arrestor screen. If
the screen is damaged or heavily
carbonized, fit a new one.
N Insert the spark arrestor and tighten
it down firmly with the combination
wrench.
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).
