use a muffler if the spark arrestor screen is missing 
or defective.
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.
Starter
Replacing the starter cord
Loosen the screws that hold the starter against the 
crankcase and remove the starter.
Pull out the cord approx. 30 cm (12 inches) and hook 
it into the notch in the rim of the pulley. Release the 
recoil spring by letting the pulley rotate slowly 
backwards.
Undo the bolt in the centre of the pulley and remove 
the drive disc (A), drive disc spring (B) and the pulley 
(C). Insert and secure a new starter cord in the starter 
pulley. Wind approx. 3 turns of the starter cord on the 
starter pulley. Fit the starter pulley so that the end of 
the recoil spring (D) hooks into the starter pulley. Now 
assemble the drive disc spring, drive disc and the bolt 
in the centre of the pulley. Carry the starter cord 
through the hole in the starter housing and the starter 
handle. Tie a good knot on the starter cord.
Tensioning the recoil spring
Hook the starter cord in the notch in the pulley and 
turn the starter pulley about 2 turns clockwise.
Note! Check that the pulley can be turned an 
additional 1/2 turn when the starter cord is pulled all 
the way out.
Stretch the line with the handle. Move your thumb and 
release the line. See the figure below.
!
WARNING! When the recoil spring is 
wound up in the starter housing it is 
under tension and can, if handled 
carelessly, pop out and cause personal 
injury.
Care must be exercised when replacing 
the return spring or the starter cord. 
Wear protective glasses and protective 
gloves.
