A slight correction of the setting may be 
necessary if engine power is not 
satisfactory:

:

Check the standard setting. 

:

Warm up the engine. 

:

Turn high speed screw (H) slightly 
clockwise (leaner) – no further than 
stop.

If the setting is too lean there is 
a risk of engine damage due to 
insufficient lubrication and 
overheating.

The carburetor adjusts automatically to 
any change in operating conditions (e.g. 
cutting at high altitude). 

The automatic adjustment process can 
be speeded up as follows: 

:

Run the engine for about 10 
seconds at full throttle – with the 
chain and bar mounted. 

:

Perform five uniform cross cuts at 
full throttle.

:

If the engine is low on power, check 
the spark arresting screen in the 
muffler.

:

Allow muffler to cool down.

Remove the screw (1).
Pull out spark arresting screen (2).
:

Clean spark arresting screen if 
necessary – if screen is damaged or 
coked up, fit a new one.

:

Refit the spark arresting screen.

:

Insert screw and tighten down.
