Adjusting the start throttle speed
The correct start throttle speed is set by means of an 
adjuster on the rear of the handle next to the cable. Use 
this screw (4 mm Allen screw) to increase or decrease the 
start throttle speed.
Proceed as follows:
1
Run the machine at idle.
2
Press the start throttle lock as described under the 
heading Starting and stopping.
3
If the start throttle speed is too low (below 4000 rpm), 
turn the adjuster screw A clockwise until the cutting 
attachment starts to rotate. Then turn A clockwise a 
further 1/2 turn.
Muffler
CAUTION!  Some mufflers are fitted with a catalytic 
converter. See chapter on Technical data to see whether 
your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to 
direct the exhaust gases away from the operator. The 
exhaust gases are hot and can contain sparks, which may 
cause fire if directed against dry and combustible 
material.
 Some mufflers are equipped with a special spark arrestor 
screen. If your machine has this type of muffler, you 
should clean the screen at least once a week. This is best 
done with a wire brush.
 On mufflers without a catalytic converter the screen 
should be cleaned weekly, or replaced if necessary. On 
mufflers fitted with a catalytic converter the screen should 
be checked, and if necessary cleaned, monthly. If the 
screen is damaged it should be replaced.
 If the screen 
is frequently blocked, this can be a sign that the 
performance of the catalytic converter is impaired. 
Contact your dealer to inspect the muffler. A blocked 
screen will cause the machine to overheat and result in 
damage to the cylinder and piston.
CAUTION!  Never use a machine with a defective muffler.
Cooling system
To keep the working temperature as low as possible the 
machine is equipped with a cooling system.
The cooling system consists of:
1
Air intake on the starter.
2
Fins on the flywheel.
3
Cooling fins on the cylinder.
4 mm
!
WARNING! Mufflers fitted with catalytic 
converters get very hot during use and 
remain so for some time after stopping. 
This also applies at idle speed. Contact 
can result in burns to the skin. 
Remember the risk of fire!
