Try to find the highest idling speed, turning the low speed 
needle L clockwise respectively counter-clockwise. When the 
highest speed has been found, turn the low speed needle L 1/
4 turn counter-clockwise.

CAUTION!  If the cutting attachment rotates when the engine 
is idling the idle adjustment screw T should be turned anti-
clockwise until the cutting attachment stops.

Adjust the idle speed using the idle adjustment screw T, if it is 
necessary to readjust. First turn the idle adjustment screw T 
clockwise until the cutting attachment starts to rotate. Then 
turn the screw anticlockwise until the cutting attachment 
stops. The idle speed is correctly adjusted when the engine 
will run smoothly in every position. The idle speed should also 
be well below the speed at which the cutting attachment starts 
to rotate.

The high speed jet H affects the engine power, speed, 
temperature and fuel consumption. If the high speed jet H is 
set too lean (screwed in too far) the engine speed will be too 
high and cause engine damage. Do not let the engine run at 
full speed for more than 10 seconds.

Note that the engine should be loaded when you adjust the 
high speed jet H. You should therefore fit the trimmer head 
T35 (2.7 mm cord) before adjusting the high speed jet. The 
cord length should be standard, i.e. to the knife on the trimmer 
guard.

Apply full throttle and turn the high speed jet H very slowly 
clockwise until the engine slows down. Then turn the high 
speed jet H very slowly anticlockwise until the engine starts to 
run unevenly. Now turn the high speed jet H slowly clockwise 
a little way until the engine runs smoothly. 

CAUTION!  For optimum adjustment of the carburettor, 
contact a qualified dealer/service workshop that has a 
revolution counter at their disposal. 

When the carburetor is correctly adjusted the machine will 
accelerate without hesitation and burble a little at maximum 
speed. It is also important that the cutting attachment does 
not rotate at idle. If the low speed jet L is set too lean it may 
cause starting difficulties and poor acceleration.

If the high speed jet H is set too lean it will result in less power, 
less performance, poor acceleration and/or damage to the 
engine.

If both the L and H jets are set too rich it will results in 
acceleration problems or too low a working speed.
