N Pull out the spark arresting
screen (2)
N Clean the dirty spark arresting
screen, replace if damaged or
heavily carbonized
N Refit the spark arresting screen
N Insert the screw
N Install the chain sprocket cover
N If the muffler plugs are missing or
damaged, mount new plugs
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 Move the Master Control lever to the
stop position (0).
N Disengage the chain brake.
N Rotate the captive nut (1)
counterclockwise until it hangs
loosely in the sprocket cover.
N Remove the sprocket cover (2) with
captive nut.
