WARNING
If the working tool or cutting attachment
continues to run when the engine is
idling, have your machine 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).
Checking the Spark Plug
N
Clean dirty spark plug.
N
Check electrode gap (A) and
readjust if necessary – see chapter
"Specifications."
N
Use only resistor type spark plugs of
the approved range.
Rectify problems which have caused
fouling of spark plug:
–
too much oil in fuel mix,
–
dirty air filter,
–
unfavorable running conditions, e.g.
operating at part load.
