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.

4

If the start throttle speed is too high, turn the adjuster 
screw A anticlockwise until the cutting attachment 
stops. Then turn adjuster screw A clockwise a further 
1/2 turn.

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 
mesh. If your machine has this type of muffler, you should 
clean the mesh at least once a week. This is best done 
with a wire brush. On mufflers without a catalytic 
converter the mesh should be cleaned weekly, or 
replaced if necessary. On mufflers fitted with a catalytic 
converter the mesh should be checked, and if necessary 
cleaned, monthly. If the mesh is damaged it should be 
replaced. If the mesh 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 mesh will cause the machine to overheat and 
result in damage to the cylinder and piston.

CAUTION!  Never use a machine with a defective muffler.
